FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with lipase is indexed in search engines, such as www.google.com or others, a nonsystematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about lipase, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to lipase, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on lipase. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to lipase, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on lipase. The Editors

CHAPTER 1. STUDIES ON LIPASE Overview In this chapter, we will show you how to locate peer-reviewed references and studies on lipase.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and lipase, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “lipase” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Exercise Training, Without Weight Loss, Increases Insulin Sensitivity and Postheparin Plasma Lipase Activity in Previously Sedentary Adults Source: Diabetes Care. 26(3): 557-562. March 2003. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: This article reports on a study undertaken to determine the effects of exercise, without weight loss, on insulin sensitivity (S1) postheparin plasma lipase activity (PHPL), intravenous fat clearance rate (K2), and fasting lipids in sedentary adults. Exercise increased S1 and both lipoprotein lipase and hepatic (liver) lipase activities without altering BMI (body mass index), waist circumference, K2, or fasting lipids. Correlations between changes in LPL and the total-to- HDL cholesterol ratio and

changes in the LPL-to-HL ratio and waist circumference were significant. The authors conclude that exercise, without weight loss, increases S1 and PHPL activity in previously sedentary adults, without changing K2 or fasting lipid levels. Therefore, even modest amounts of exercise in the absence of weight loss positively affect markers of glucose and fat metabolism in previously sedentary, middle-aged adults. 1 figure. 1 table. 26 references.
Federally Funded Research on Lipase The U.S. Government supports a variety of research studies relating to lipase. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to lipase. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore lipase. The following is typical of the type of information found when searching the CRISP database for lipase: •
Project Title: ALCOHOL AND CHRONIC DISEASE AMONG VULNERABLE POPULATIONS Principal Investigator & Institution: Rimm, Eric B.; Associate Professor; Nutrition; Harvard University (Sch of Public Hlth) Public Health Campus Boston, Ma 02115 Timing: Fiscal Year 2004; Project Start 01-SEP-1997; Project End 31-MAR-2009 Summary: (provided by applicant): Among healthy populations, the benefits of moderate alcohol consumption are well documented. However, more than 7.5 million Americans are survivors of myocardial infarction (MI) and the epidemic of obesity has given rise to an even larger unhealthy population with dyslipidemia,hypertension, low HDL-C, and hyperglycemia (i.e. metabolic syndrome). The influence that alcohol has on prognosis among these "at risk" groups is crucial for informed decision-making by patients, physicians, and policy-makers. We propose to examine alcohol and chronic disease in vulnerable populations among 121,700 women (32,826 with stored blood samples) in the Nurses' Health Study (1976-2006) and 51,529 men (18,100 with stored blood samples) in the Health Professionals Follow-up Study (1986-2006). First, we will study alcohol intake and risk of mortality among an estimated 3,345 women and 2,835 men with confirmed incident non-fatal MI. Secondly, using blood markers of dyslipidemia and abnormal glucose homeostasis, we will examine alcohol and coronary heart disease (CHD) among participants with metabolic syndrome in a nested case control (1:2) study among the projected 680 women and 534 men who provided blood samples and subsequently developed CHD. Finally, because the purported benefit of

alcohol consumption is attributed principally to increased HDL-C, we will examine CHD risk associated with gene-alcohol interactions in genes that modulate HDL-C levels. Specifically, alcohol dehydrogenase-3, hepatic lipase, lipoprotein lipase, cholesteryl ester transport protein, and endothelial lipase. The well characterized large cohorts of women and men with stored blood samples provide an unparalleled opportunity to elucidate the health effects of alcohol among high risk patients. Furthermore, knowledge of populations that may benefit from alcohol (or be at greatest risk) will help in the understanding of the pathophysiology of CHD and aid in the development of more complete clinical guidelines for the growing population of individuals at risk for coronary disease and mortality.

LIPID
METABOLISM
AND
Principal Investigator & Institution: Chan, Lawrence; Professor of Medicine; Molecular and Cellular Biology; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 15-DEC-1993; Project End 30-NOV-2005 Summary: (provided by applicant): The primary objective is to advance our knowledge of lipid metabolism and atherosclerosis using animal models. A major area is the role of 12/15-lipoxygenase (LO) in atherosclerosis. 12/l5LOs are lipid-peroxidizing enzymes that oxygenate polyenoic fatty acids to their corresponding hydroperoxy derivatives. 12/15LOs have proatherogenic properties via their capacity to oxidize LDL, as well as antiatherogenic activities via their predominantly anti-inflammatory action. We previously showed that macrophage-specific 15LO overexpression in rabbits protects against atherosclerosis. In pilot experiments we found that, compared to 12/15LO+/+ apoE-/- mice, 12/15LO-/- apoE-/- mice are protected against atherosclerosis, a finding that is at variance with that of. A major goal of this application is to examine the biochemical milieu associated with 12/15LO expression that may underlie the divergent effects of the enzyme on atherosclerosis. Another major area is the role of intracellular lipolysis in lipid homeostasis. We produced perilipin (plin) knockout mice that displayed constitutional activated lipolysis. Perilipin is a major adipose lipid droplet protein that regulates the activity of hormone-sensitive lipase. Plin-/- mice were lean and resistant to diet-induced obesity. Breeding the plin-/- alleles into ob/ob and db/db mice reversed their obesity phenotype. Interestingly, ruptured atherosclerotic plaques in humans and advanced plaques of apoE-/- mice expressed perilipin. We will investigate the role of 12/15LO and perilipin with 5 specific aims. In the first 2 aims, we will study atherosclerosis development in 12/15LO-/- apoE-/- and 12/15LO+/+ apoE-/- mice, and, identify and quantify the eicosanoids and other metabolites in the atherosclerotic aortas from the 2 genotypes. In aims 3 and 4, to obtain mechanistic insight into the obesity-resistant phenotype of plin-/- mice, we will perform biochemical and molecular characterization as well as in vivo stable isotope and energy expenditure experiments on plin+/+ and plin-/- mice with and without ob/ob or db/db background. The creation of non-obese ob/ob and db/db mice (i.e., those that also inherited the plin-/- alleles) provides a unique opportunity to study the role of leptin in lipid and carbohydrate homeostasis in the presence and absence of obesity. Since perilipin, a lipid dropletassociated protein, is expressed in atherosclerotic lesions, in the last aim and in collaboration with we will compare the atherosclerosis susceptibility and plaque morphology of plin-/- and plin+/+ mice bred into apoE-/- and LDLR-/- background. We believe that the mechanistic experiments proposed will advance our understanding of lipid and carbohydrate metabolism, energy homeostasis, and atherosclerosis.

Project Title: ANTHRACYCLINE CARDIOTOXICITY--OXIDATIVE STRESS Principal Investigator & Institution: Sarvazyan, Narine; Associate Professor; Physiology; Texas Tech University Health Scis Center Health Sciences Center Lubbock, Tx 79430 Timing: Fiscal Year 2002; Project Start 01-APR-1999; Project End 31-MAR-2004 Summary: Doxorubicin and its derivatives are among the most potent anticancer drugs known. Unfortunately their therapeutic efficacy is severely restricted by a doseaccumulated cardiotoxicity. Our preliminary results using adult rat cardiomyocytes as a working model, have shown evidence for the mechanism which could explain how reactive oxygen species generated by doxorubicin provoke myofibrillar degeneration while not causing severe oxidative damage. Specifically, 1) we visualized directly doxorubicin accumulation in cardiac mitochondria and subsequent increase in intracellular oxidation in living cardiomyocytes, 2) observed that doxorubicin administration is associated with redistribution of the protein kinase C epsilon isoform from cytosol to myofibrils, and 3) detected disruption of the periodicity of actin staining after repetitive exposure of myocytes to clinically relevant drug concentrations. Based on these data we propose the following sequence of events: doxorubicin rapidly accumulates in cardiac mitochondria; it then initiates lipid peroxidation via formation of superoxide and drug complexes with transition metals; and although the degree of lipid peroxidation is small and no significant membrane damage occurs, it leads to the activation of phospholipases; lipase thereupon release several second messengers, including arachidonic acid, activating a specific protein kinase C isoform; the kinase then initiates myofibrillar degeneration. To support the above hypothesis we aim to 1) establish a causal relationship between observed doxorubicin-induced kinase translocation and increased free radical formation; 2) to determine whether doxorubicininduced free radicals and/or protein kinase C translocation are prerequisites for changes in myocyte myofibrillar organization and cell contractility; 3) to uncover role of phospholipase A2 in doxorubicin-induced activation of kinase and ensuing changes in myofibrillar organization and contractility. The proposed experiments aim to reveal explicit pathways through which reactive oxygen species are involved in anthracyclineinduced cardiomyopathy. The studies will also provide new information about kinases involvement in myofilament degeneration and interaction between reactive oxygen species and signal transduction pathways.

Project Title: ANTIBODIES TO LIPOPROTEIN LIPASE AND ATHEROSCLEROSIS Principal Investigator & Institution: Reichlin, Morris; Vice President of Research; Oklahoma Medical Research Foundation Oklahoma City, Ok 731045005 Timing: Fiscal Year 2002; Project Start 05-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Premature atherosclerosis in patients with Systemic Lupus Erythematosus (SLE) has been recognized for the past 25 years. As much as a 50fold increase in risk for coronary artery disease has been found in SLE patients compared to controls and an increased risk for thrombotic cerebrovascular disease has also been recognized. In the past decade lipid abnormalities have been recognized in SLE patients that are "proatherogenic". These include elevated LDL cholesterol, low HDL cholesterol and elevated triglyceride levels that are not due to nephrotic syndrome. Careful clinical studies suggest that conventional risk factors such as age, sex, smoking, hypertension, etc., do not completely account for the prevalence of premature

atherosclerosis. Indeed, there appears to be an element of risk conferred by the lupus process itself We postulate that this mechanism of the SLE associated risk lies in autoimmune events that perturb lipid homeostasis in the direction of elevated triglycerides and cholesterol. We further suggest that part of this effect is due to an immune response to lipoprotein lipase which occurs in 50% of SLE patients and promotes hypertriglyceridemia. In addition, autoantibodies to apolipoprotein A-1, Apo B and Apo E may perturb lipid transport and promote decreased HDL cholesterol and increased LDL cholesterol. Our plan is to combine our expertise in autoantibody research with epidemiologic methods. We will conduct a prospective study of SLE patients and their matched controls to evaluate these immune responses on lipid levels, in the presence of conventional risk factors and confounders, and their association with premature atherosclerosis. Recognition of autoimmune mechanisms that promote elevated triglycerides could lead to specific interventions as therapy or even possibly prevention of premature atherosclerosis.

Project Title: ANTIGEN SPECIFIC RESPONSES TO BORRELIA Principal Investigator & Institution: Benach, Jorge L.; Professor, Molecular Genetics and Microb; Molecular Genetics & Microbiol; State University New York Stony Brook Stony Brook, Ny 11794 Timing: Fiscal Year 2002; Project Start 01-DEC-1993; Project End 31-MAY-2003 Summary: (Adapted from the applicant's abstract): The main and long term goal of this application is to understand the mechanism of action of bactericidal antibodies in Borrelia infections. A number of monoclonal antibodies have been discovered that can kill Borrelia burgdorferi without the assistance of complement, and the Fab fragments of the antibodies have the same bactericidal activity. Earlier studies showed that these antibodies function by lysis of the outer membrane in a Ca++ dependent medium process. This application is based on the hypothesis that complement independent bactericidal antibodies represent a novel and fundamental mechanism of host resistance in infections with Borrelia, and possibly in infections with other bacteria. The Research Plan is based on three underlying hypotheses that support the main goal of this application to characterize the mechanisms by which bactericidal antibodies can destroy Borrelia spp. The first approach will be to examine the antibodies themselves for possible catalytic properties which could result in a breakdown of the antigen leading to changes in the physical association of the antigen with other outer membrane molecules. The possibility that the antibodies could induce unique conformational changes in their antigens, which in turn could affect the topology and integrity of the outer membrane will also be evaluated. The second approach will be to test the hypothesis that the antibody-antigen complex induces the activation of lytic enzymes through an outer membrane signal transduction mechanism. Specifically, the identification and role of lipases and phospholipases in Borrelia will be evaluated. Such enzymes exist in these organisms and should be involved in the lysis of the outer membrane. If this mechanism of killing Borrelia is found to occur, it will represent a novel, and overlooked form of host defense. The third approach will be to test the possibility that bactericidal antibodies are a major form of host defense in Borrelia infections. Passive immunization studies will be conducted with the bactericidal antibodies in complement deficient (transgenic) mice to determine their role in preventing infection in a complement independent manner. Other studies will be involved in raising targeted bactericidal antibodies to antigens expressed in vivo. The possibility that the bactericidal antibodies may select more invasive phenotypes will also be evaluated.

Project Title: APO E GENOTYPE AND HDL CHANGES WITH EXERCISE TRAINING Principal Investigator & Institution: Hagberg, James M.; Professor; Kinesiology; University of Maryland College Pk Campus College Park, Md 20742 Timing: Fiscal Year 2002; Project Start 01-JUN-1998; Project End 31-MAY-2004 Summary: (Adapted from the Applicant's Abstract): Abnormal plasma lipids are a major modifiable risk factor for cardiovascular (CV) disease in older persons. Polymorphic variation at numerous gene loci independently and via interactions with environmental factors affect plasma lipid levels. A cross-sectional study and preliminary data suggest that apolipoprotein E (APO E) genotype affects the HDL-C and HDL2-C increases that occur with exercise training. Thus, in healthy, sedentary, middle-aged and older subjects, the investigators will test their primary hypothesis: HDL-C and HDL2-C levels increase more with exercise training in APO E2/3 than in APO E3/4 genotype individuals. Preliminary data also indicate that lipoprotein lipase (LPL) Pvull genotype affects HDL-C and HDL2-C increases resulting from exercise training. Thus, they will test their secondary hypothesis: HDL-C and HDL2-C levels increase more with exercise training in LPL Pvull -/- than in LPL Pvull +/+ or +/- genotype individuals. Exploratory analyses will determine if variations at another LPL and 3 hepatic lipase (HL) gene loci affect the exercise training-induced HDL-C and HDL2-C increases and if, as with preliminary data, LPL and HL activities change differently with exercise training among genotype groups. After screening subjects for APO E genotype, they will be stabilized on an AHA Step I diet. Subjects then complete Baseline Testing, 6 months of exercise training and Final Testing. If VO2max, body composition, or intra-abdominal fat change differently among genotype groups with exercise training, they will be included in linear regression models to assess the independent effects of genetic and non-genetic variables on lipid changes with exercise training. Results consistent with the hypotheses will identify persons who obtain the greatest CV disease risk reductions, resulting in the optimal stratifying of exercise training to those benefiting the most. Conversely, identifying persons who will improve their lipoprotein lipids the least with exercise training would allow them to focus on interventions that might be more efficacious for them.

Project Title: BEHAVIOR MODIFICATION AND PHARMACOTHERAPY FOR OBESITY Principal Investigator & Institution: Wadden, Thomas A.; Professor; Psychiatry; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-AUG-1999; Project End 31-JUL-2003 Summary: Obesity is one of our nation's most serious health problems. The treatment of this disorder experienced a serious setback last year when two popular weight loss medications -- fenfluramine and dexfenfluramine -- were withdrawn from the market because of concerns that they were associated with valvular heart disease. Despite this unfortunate occurrence, it appears that pharmacotherapy will play an increasingly important role in the management of obesity in the next decade. In November 1997, the Food and Drug Administration approved sibutramine, a serotonin and norepinepherine re-uptake inhibitor, for "weight loss and maintenance of weight loss". Orlistat, a gastric and pancreatic lipase inhibitor, is now being considered for similar approval, with

several other medications likely to follow. Previous studies indicate that optimal weight losses and improvements in health are likely to be obtained when behavioral and pharmacologic interventions are combined. Behavior therapy facilitates adherence to exercise and medication recommendations, whereas pharmacotherapy, by reducing hunger and increasing satiety, aids efforts to consume a reduced calorie diet. Long-term pharmacotherapy also holds promise of improving the maintenance of weight loss, a shortcoming of behavioral treatment. The proposed study will examine, in an 18-month trial, the separate and combined effects of behavior therapy and pharmacotherapy for obesity. A total of 296 obese men and women (BMI greater than 32 kg/m2) will be randomly assigned to one of four conditions: 1) Medication (i.e., sibutramine) Plus Standard Care; 2) Medication Plus Individual Behavior Modification (provided by a physician in brief visits); 3) Medication Plus Group Behavior Modification; or 4) Group Behavior Modification Alone. We predict that subjects treated by medication, combined with either individual or group behavior modification, will achieve significantly greater weight losses and improvements in health than those treated by Medication Plus Standard Care. This will result from the latter subjects' significantly better adherence to diet, exercise, and medication recommendations. We also predict that subjects treated by medication plus behavior modification (in individual or group sessions) will achieve significantly greater weight losses (particularly during the last 9 months) than persons who receive Group Behavior Modification Alone. If confirmed, the above findings will have important implications for treating obesity in primary care. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CELL SIGNALING: MACROVASCULAR COMPLICATIONS OF DIABETES Principal Investigator & Institution: Bornfeldt, Karin E.; Pathology; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 30-SEP-1998; Project End 30-NOV-2005 Summary: (provided by applicant): A majority of people with diabetes die of cardiovascular disease caused by atherosclerosis that is accelerated by diabetes. The factors that drive diabetes-accelerated atherosclerosis are still poorly understood. Our recent studies on a new porcine model show that diabetes in combination with elevated lipid intake causes increased accumulation and proliferation of arterial smooth muscle cells (SMCs) in lesions of atherosclerosis. The increased SMC proliferation occurs concomitant with hyperglycemia and elevated levels of plasma triglycerides. High glucose levels are not sufficient to induce SMC proliferation, but certain fatty acids common in triglycerides (oleate and linoleate) stimulate SMC proliferation in the presence of insulin-like growth factor I (IGF-I). We propose that diabetes leads to an increased amount of IGF-I and of lipoprotein lipase in lesion macrophages, and that lipoprotein lipase degrades triglycerides into free fatty acids that act in synergy with IGF-I to stimulate SMC proliferation. Our goal for the next five years is to address the following questions: 1. Do oleate and linoleate enhance the growth-promoting effects of IGF-I on SMCs? 2. How do oleate and linoleate synergize with the growth-promoting action of IGF-I in SMCs? 3. Does lipoprotein lipase produced by lipid loaded macrophages increase SMC proliferation by generating oleate and linoleate? 4. Does glucose or lipids associated with diabetes stimulate SMC proliferation, lipoprotein lipase and IGF-I in lesions of atherosclerosis and does lack of macrophage-derived lipoprotein lipase result in reduced SMC proliferation? We will use several animal models of diabetes-associated atherosclerosis, isolated arterial SMCs for signal transduction studies as well as a co-culture model of monocyte derived macrophages

and SMCs. Increased understanding of the regulation of SMC proliferation and accumulation in diabetic lesions of atherosclerosis may provide the basis information necessary for development of highly specific drugs that can prevent lesion progression and formation of vulnerable lesions that are likely to cause the clinical symptoms of cardiovascular complications in diabetes.

Project Title: CELL SURFACE ACTIVITIES IN LIPOPROTEIN CATABOLISM Principal Investigator & Institution: Orlando, Robert A.; Assistant Professor; Biochem and Molecular Biology; University of New Mexico Albuquerque Controller's Office Albuquerque, Nm 87131 Timing: Fiscal Year 2002; Project Start 18-SEP-2000; Project End 30-NOV-2003 Summary: adapted from applicant's abstract): Studies in this application propose to investigate this apparent synergistic relationship between HSPG and LRP or megalin, that is necessary for lipoprotein/lipase clearance by cells. Using quantitative biochemical procedures we will determine if ligands are 1) transferred to the endocytic receptors for internalization following their initial binding to HSPG, or 2) if the HSPG and endocytic receptors are cointernalized with bound ligand. These studies will aid in determining if LRP and megalin can regulate ligand sequestration or lipolytic enzyme activities by controlling the amount of HSPG that is present on the cell surface through endocytosis. We also plan to identify the proteoglycan-like molecule that coprecipitates with megalin and LRP, and determine if disrupting its interactions with LRP and megalin prevents the uptake of lipoproteins by cells. As a second goal, studies are proposed to quantitatively evaluate the changes in LRP and megalin expression during adipocyte differentiation, and assess the functional role of these receptors in intracellular lipid accumulation. Supporting data have found that expression of LRP and megalin in differentiating adipocytes is responsive to glucocorticoid- and cAMPdependent signaling pathways. Based on this observation the applicant plans to identify and characterize the cis- and trans-activating elements in the promoters of LRP and megalin that are responsible for regulating their expression levels during adipocyte development. Together, these studies will help 1) better define the functional roles of LRP and megalin in lipoprotein clearance, 2) begin to understand the molecular basis of their tissue-specific expression, and 3) advance our knowledge of cardiovascular health and disease such as atherosclerosis and obesity.

Project Title: CENTRAL OOBESITY SYNDROME IN A SUBSET OF TYPE 1 DIABETES Principal Investigator & Institution: Brunzell, John D.; Prpfessor of Medicine; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 01-SEP-1976; Project End 31-MAR-2007 Summary: (provided by applicant): Project 2 started as an ancillary study of lipoprotein metabolism to the NIH sponsored clinical trial of intensive diabetes therapy in type 1 diabetics to prevent microvascular disease called the Diabetes Control and Complication Trial (DCCT). The Epidemiology of Diabetes Intervention and Complications (EDIC) is a ten year non-interventional follow-up of DCCT to evaluate the natural history of macrovascular and nephropathy complications in type 1 diabetes. In DCCT, we found that atherogenic small dense LDL were increased with hyperglycemia, microalbuminuria and were increased in that subset of subjects who gained excess

weight as a complication of intensive diabetes therapy during DCCT. Those who gained weight with intensive diabetes therapy were centrally obese, insulin resistant, hypertensive, dyslipidemic and had type 2 diabetic parents. This suggests they had inherited the metabolic-central obesity syndrome in addition to type 1 diabetes. This new proposal will use the phenotypes of 1) excessive weight gain with intensive diabetes therapy and 2) the presence of small dense LDL particles as markers of the central obesity-insulin resistance metabolic syndrome that occurred in this subset of type 1 subjects during intensive diabetes therapy. These markers of the central obesity syndrome will be used to predict the occurrence of cardiovascular events and the development or progression of microalbuminuria during the course of EDIC. Candidate genes for development of the central obesity syndrome and for the interaction of excess weight gain with the development of hypertension will be examined. Intraabdominal fat by CT scan and postheparin plasma hepatic lipase will be measured to further develop the phenotype associated with the excessive weight gain with intensive therapy and with development of nephropathy in the Seattle cohort and three Minnesota cohorts of EDIC. The development of the central obesity syndrome with intensive diabetes therapy in type 1 diabetic patients may predispose them to increased risk of cardiovascular disease and nephropathy. If so, modifications of clinical therapy will need to be made in this subset of individuals. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CHARACTERIZATION OF A NOVEL LYSOPHOSPHOLIPASE Principal Investigator & Institution: Huang, Ying; Pharmacology; Upstate Medical University Research Administration Syracuse, Ny 13210 Timing: Fiscal Year 2002; Project Start 02-AUG-2002; Project End 31-JUL-2004 Summary: (provided by applicant): Numerous studies have demonstrated that phospholipids and lysophospholipids act as lipid mitogens that affect cell proliferation and survival by altering various cell signaling pathways. Intracellular levels of phospholipids and lysophospholips are tightly regulated by their respective lipases and thus, the expression and activity of these enzymes is critical for cellular homeostasis. We have cloned a cDNA that encodes a novel putative lysophospohlipase. In view of its predicted molecular mass of 34 kDa, we have named it LPL34 (lysophospholipase 34). Our preliminary results indicate that the LPL34 mRNA is highly expressed in normal colon mucosa but absent or reduced in established colon cancer cell lines. Analysis of primary colon tumors and their matching normal tissues also revealed that the expression of LPL34 is absent or reduced in 4/4 tumor tissues. Consistent with these results, expression of exogenous LPL34 in cancer cells lacking endogenous LPL34 results in growth inhibition. We have proposed studies to further examine the role of LPL34 in digestive diseases such as colon cancer. We will analyze a larger pool of fresh-frozen and paraffin-embedded tissue specimens for the expression of LPL34 at both mRNA and protein levels. We will also investigate a correlation between LPL34 status and clinicopathological features. To investigate the molecular basis of LFL34-mediated growth suppression, we will study the effect of LPL34 on PI3-K/Akt and ERKdependent mitogenic and survival signaling pathways. To determine whether lipase activity is critical LPL34-mediated growth suppressive effect, site-directed mutagenesis approach will be used to mutate the conserved lipase motif 'GHSMG' and effects of mutated LPL34 on cell growth and mitogenic signaling pathways will be investigated. These are exploratory /developmental studies that, upon conclusion, will provide us with sufficient new data and reagents that will form the basis of future in-depth studies

Project Title: COMMON VARIANTS IN CANDIDATE GENES AND PREMATURE MI RISK Principal Investigator & Institution: Schwartz, Stephen Marc.; Assistant Professor; Epidemiology; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2001; Project Start 15-SEP-1998; Project End 31-AUG-2004 Summary: (Adapted from Investigator's Abstract) Inherited factors play a role in the pathogenesis of myocardial infarction (MI), and there is growing interest in identifying common genetic susceptibility markers that interact with common environmental exposures to contribute to the occurrence of MI in the population. The preliminary data address the contribution of common genetic and environmental factors to the risk of MI among women under 45 years of age. Those data show that common polymorphisms in genes coding for two clotting factors, coagulation Factor V and coagulation Factor II, are risk factors for MI only among cigarette smokers in this sample. These relationships, and others observed, provide strong evidence of gene-environment interactions between thrombotic and atherosclerotic factors in early-onset MI. The plan is to extend this work to investigate the relationship of common putative susceptibility genotypes to the occurrence of early-onset MI in both men and women. One intent is to determine whether the risk of early-onset MI is related to interactions between environmental factors (e.g., cigarette smoking, exercise, alcohol consumption) and common polymorphisms in genes coding for thrombotic factors (coagulation Factor V, coagulation Factor II, plasminogen activator inhibitor-1, and beta-fibrinogen) and atherosclerotic factors (the adhesion molecule E-selectin and metalloproteinase stromelysin-1; the lipid metabolism enzymes paraoxinase, lipoprotein lipase, cholesterol ester transfer protein; and the apolipoproteins apolipoprotein E and apolipoprotein B). Additionally, there are plans to determine whether the risk of early-onset MI is related to interactions between plasma lipoprotein(a) levels (which are largely genetically determined) and environmental risk factors and/or polymorphisms in the candidate genes. Interactions among candidate polymorphisms will also be assessed. Cases will be all 18-49 year old male (n=386) and 18-59 female (n=386) residents of King, Pierce and Snohomish counties, Washington State, newly diagnosed with a first, non-fatal MI during a 3.25 year period. Demographically similar controls (n=772) will be ascertained and recruited through random digit telephone dialing. Cases and controls will be interviewed in person to assess medical and behavioral characteristics related to MI risk. A venous blood sample will be obtained and processed into aliquots of plasma and white cells. DNA extracted from the white cells will be tested using the polymerase chain reaction (PCR), PCR/restriction fragment length polymorphisms (RFLP), and oligonucleotide ligation assays to determine the genotypes of interest. Plasma will be tested for lipid, lipoprotein, and homocysteine concentrations. Analyses will address both the overall association between the genotypes and MI risk, along with posited gene-environment and gene-gene interactions. In addition to providing powerful tests of the Specific Aims, this large study will provide a unique resource for testing future hypotheses regarding the role of common genetic susceptibility factors in the pathogenesis of early-onset MI among both men and women.

Project Title: CORTISOL, CENTRAL OBESITY, AND INSULIN RESISTANCE Principal Investigator & Institution: Purnell, Jonathan Q.; Associate Professor; Medicine; Oregon Health & Science University Portland, or 972393098 Timing: Fiscal Year 2002; Project Start 15-AUG-2000; Project End 31-JUL-2004 Summary: (adapted from the application) Central (visceral) obesity contributes to an excess risk of diabetes, dyslipidemia, hypertension, and premature death from coronary heart disease. A feed-back loop model of weight regulation has emerged from recent studies of animals and humans: afferent hormones signal amount of fat mass to the central nervous system; weight regulation centers in the hypothalamus interpret these signals and control efferent systems including appetite, energy expenditure, and enzymes in the fat cell, such as lipoprotein lipase, that facilitate partitioning of energy into lipid storage. It is proposed in this grant that the hypothalamic-pituitary-adrenal axis is an effector system of hypothalamic weight regulatory centers and that increased cortisol production rates in the obese state directly regulate enzyme transcription in the fat cell to promote lipid uptake and central fat distribution. Cross sectional data from lean and obese humans using stable isotope enrichment determined by mass spectroscopy demonstrate that increases in cortisol production rates across the physiological range are associated with increased adipocyte lipoprotein lipase activity, accumulation of fat mass independent of non-fat mass, increased visceral fat, and increased insulin resistance. These findings, however, do not establish whether increased cortisol production causes, or is simply associated with these variables. To directly test whether cortisol enhances lipid uptake, fat mass accumulation, increased visceral fat mass, and insulin resistance, it is proposed to study the effect of administration of increasing doses of hydrocortisone (including doses within the physiological replacement range) in subjects with complete adrenal failure on these parameters. Finally, leading cellular candidates for the regulation of adipocyte lipoprotein lipase gene expression and fat cell differentiation, including PPAR-gamma and C/EBP, will be measured in adipose samples from the subjects in these studies to provide a mechanistic link between peripheral signaling systems such as cortisol and the adipocyte enzymes involved with fat partitioning. These studies will not only provide insight into the mechanisms of central obesity and its metabolic consequences, they also have great importance to clinicians who care for subjects with adrenal insufficiency as to the consequences of recommended replacement doses of cortisol on risk factors for heart disease.

Project Title: ENDOCANNABINOID SITES AS THERAPEUTIC TARGETS Principal Investigator & Institution: Makriyannis, Alexandros; Board of Trustees' Distinguished Profess; None; University of Connecticut Storrs Unit 1133 StorrsMansfield, Ct 06269 Timing: Fiscal Year 2003; Project Start 30-SEP-1994; Project End 31-MAR-2006 Summary: (provided by applicant): Marijuana is the most widespread illegal drug of abuse in Western societies. Its main active ingredient, delta-9-tetrahydrocannabinol, acts by binding to specific membrane receptors called cannabinoid receptors. Activation of these receptors exerts intense effects in humans, suggesting that endogenous cannabinoid (endocannabinoid) substances may contribute in important ways to brain functions such as cognition, mood and pain sensation. Several endocannabinoid substances have been identified, including anandamide and 2-arachidonylglycerol (2AG). Anandamide and 2-AG are released from neuronal and non-neuronal cells and
14
Lipase
activate cannabinoid receptors with high affinity. After release, anandamide and 2-AG undergo a rapid inactivation process, which may play an important role in terminating their biological actions. They may be taken up by cells via high-affinity transport system(s) and then broken down by distinct enzymatic activities: anandamide by fatty acid amide hydrolase (FAAH) and 2-AG by monoacylglycerol lipase (MGL). In initial studies, we have molecularly cloned a cDNA encoding for rat brain MGL and provided evidence that this enzyme may serve an important function in 2-AG inactivation. Based on these results, we propose to develop novel chemical probes that act as substrates or inhibitors for brain MGL. The first aim of the proposed research is to define the structural requirements involved in the recognition and hydrolysis of 2-AG by MGL, and develop a pharmacophore profile for MGL inhibition. In initial experiments we have molecularly cloned a cDNA encoding for rat brain MGL and developed an adenovirus-mediated MGL over-expression system in mammalian HeLa cells. Using this system, we will explore the structure-activity relationships of 2-AG hydrolysis by rat brain MGL. Specifically, we will design and synthesize novel 2-AG analogs and test them for their ability to serve as substrates or inhibitors for MGL and enhance 2-AG signaling in intact cells. The second aim of the proposed research is to develop chemically reactive 2-AG analogs, which may serve as covalent MGL ligands. Covalent, radioactively labeled ligands for MGL may be useful tools in molecular studies of this enzyme. We will design and synthesize potential covalent ligands for MGL based on the structure of 2-AG, and test them for their ability to interact irreversibly with MGL. These studies will set the stage for the elaboration of potent and selective inhibitors that target either 2-AG or anandamide deactivation and may open novel therapeutic avenues for the treatment of neuropsychiatric and substance abuse disorders.

Project Title: ENZYMATIC TOOLS FOR DEGRADING TISSUE AND PRESERVING RNA Principal Investigator & Institution: Latham, Gary J.; Senior Scientist; Ambion, Inc. Austin, Tx 787441832 Timing: Fiscal Year 2002; Project Start 27-SEP-2002; Project End 31-AUG-2003 Summary: (provided by applicant): Intact RNA is an obligate starting material for expression profiling technologies that can link specific molecular events with disease phenotypes. RNA isolations from tissue currently require invasive mechanical force to disrupt the cellular architecture. Such mechanical approaches are tedious and potentially inefficient. They also expose the operator to possible biohazards. As a result, the development of a "closed system" for RNA isolation is needed to enable the highthroughput recovery of RNA from tissues such as biopsies using a safeguarded platform that can process dozens or hundreds of tissues at once. We proposed to achieve this goal through the use of "MELT" (Multi-Enzymatic Liquefaction of Tissue) technology. This technology will harness the degrading power of enzymes that have evolved together as a biological tool set for the decomposition of complex food sources. We refer to this tool set as an "enzyme community." Since some enzyme communities (e.g., the secreted enzymes of bacterial pathogens) mimic the spectrum of activities needed to digest tissue, these collections are an ideal repository for tissue-degrading enzymes. We propose to characterize and blend enzyme activities to create a MELT reagent that can rapidly degrade tissues, "freeze" mRNA expression profiles, and stabilize the RNA for downstream analyses.

Project Title: ETIOLOGY OF NEPHROPATHY AND HYPERTENSION IN AASK PATIENT Principal Investigator & Institution: Lipkowitz, Michael S.; Medicine; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2002; Project Start 01-AUG-2000; Project End 31-JUL-2005 Summary: (adapted from the application) We will study the etiology of hypertension and nephropathy in the majority of the 1094 African-American patients in the AfricanAmerican Study of Kidney Disease in Hypertension (AASK). The AASK study is an NIH sponsored clinical multicenter trial comparing the effect of two levels of blood pressure control and three antihypertensive regimens on progression of hypertensive nephropathy in African Americans. There is a disproportionate number of African Americans with hypertensive target organ damage, suggesting a genetic susceptibility in this population; paradoxically, few studies have been performed to evaluate such genetic predisposition to disease in this high risk population. The patients of the AASK study offer a unique opportunity to prospectively determine the genetic factors involved in hypertension and hypertensive target organ damage within a high risk and understudied population. The proposed studies will immortalize white blood cells from patients to provide a renewable source of tissue and DNA from this unique study group, and follow two approaches in assessing the etiology of hypertension, nephropathy, and their sequelae: 1. Studies are proposed to determine whether polymorphisms in candidate genes for hypertension, renal failure, and cardiac disease, including renin-angiotensin system genes, insulin resistance (beta3-adrenergic receptor and lipoprotein lipase) genes, Liddle's syndrome (beta and gammaENaC) genes, and others are related to hypertension or renal failure, severity/rate of progression of renal disease, severity/refractoriness of hypertension, electrocardiographic left ventricular hypertrophy, cardiovascular morbidity and mortality, and overall morbidity and mortality. 2. Additional studies will employ a new technique, mapping by admixture linkage disequilibrium (MALD), which uses the linkage disequilibrium caused by recent admixture of founder populations to localize genes linked to a particular phenotype within a 5-20 centiMorgan region in a genome-wide screen. By utilizing microsatellite markers from the carefully phenotyped patients of the AASK Study it should be possible to identify regions of interest containing genes associated with hypertension, renal failure, and the outcomes described above for candidate genes.

Project Title: EVASION OF NADPH OXIDASE BY SALMONELLA LIPASES Principal Investigator & Institution: Mccollister, Bruce D.; Medicine; University of Colorado Hlth Sciences Ctr P.O. Box 6508, Grants and Contracts Aurora, Co 800450508 Timing: Fiscal Year 2004; Project Start 01-JUL-2004; Project End 31-MAR-2009 Summary: (provided by applicant): The ability of Salmonella to survive within professional phagocytes is paramount to its pathogenicity, as strains incapable of survival in mononuclear phagocytes are severely attenuated in mice. Survival of Salmonella within phagocytes is tightly associated with its ability to halt maturation of the phagosome along the endocytic pathway. We have recently discovered that Salmonella pathogenicity island 2 (SPI2)-encoded effector proteins remodel the phagosome by interfering with the TNFalpha/TNFRp55 signaling cascade that directs delivery ofNADPH oxidase-containing vesicles to the vicinity of the Salmonella phagosome. I plan to test the hypothesis that, by cleaving glucosylceramide, glucosylceramidase interferes with TNFRp55 signaling and blocks migration of NADPH

oxidase-harboring vesicles to the vicinity of the Salmonella phagosome. The specific aims are: 1) To determine the role of glucosylceramidase in the pathogenesis of Salmonella infections. Glucosylceramidase mutants will be constructed to examine the effect on both survival of Salmonella in macrophages and inhibition NADPH oxidase trafficking. 2) To examine the effect of Salmonella-encoded glucosylceramidase on macrophage lipid metabolism. Wildtype and glucosylceramidase-deficient Salmonella will be used to infect macrophages to assess global changes in the sphingomyelin pathway. Purified glucosylceramidase will be tested for lipid metabolizing activity, and immunocytochemistry will be used to visualize the effect of glycosylceramidase on trafficking of NADPH oxidase-containing vesicles. 3) To determine the role of glucosylceramidase on avoiding IFN( activated trafficking of NADPH oxidase. In this section, I will elucidate the mechanisms by which IFN\gamma stimulates antiSalmonella activity dependent upon the NADPH oxidase. The ability of IFNgamma to stimulate glucosylceramide synthesis will be examined as well. These studies will not only enhance our understanding of Salmonella pathogenesis but will also identify potential targets for the development of new therapeutic strategies against intracellular pathogens.

Principal Investigator & Institution: Nicklas, Barbara J.; Associate Professor; Internal Medicine; Wake Forest University Health Sciences Winston-Salem, Nc 27157 Timing: Fiscal Year 2002; Project Start 01-JUL-2002; Project End 30-JUN-2007 Summary: (provided by applicant) Aerobic exercise (AEX) intensity may be an important factor affecting the selective loss of abdominal fat when combined with a hypocaloric diet (DIET). The goal of this study is to determine the cellular mechanisms by which AEX intensity affects the loss of abdominal (both subcutaneous and visceral) adipose tissue under conditions of equal energy deficit in postmenopausal women with abdominal obesity. The hypothesis is that, compared to DIET alone or DIET with lowintensity AEX, DIET with high-intensity AEX will augment the loss of abdominal fat and improvements in metabolic cardiovascular disease (CVD) risk factors due to greater reductions in lipoprotein lipase (LPL) activity, and to greater increases in lipolysis, in abdominal, relative to gluteal, adipose tissue. The specific aims are: 1) to determine the cellular mechanisms by which DIET alone, or DIET combined with low- or highintensity AEX, affects region-specific fat loss by measuring changes in abdominal and gluteal adipose tissue LPL activity and lipolysis in postmenopausal women with abdominal obesity; and 2) to determine the effects of DIET alone, or DIET combined with low- or high-intensity AEX on lipoprotein lipids, glucose tolerance, and insulin levels in these women. We also will measure messenger ribonucleic acid (mRNA) levels of genes that may be involved in the regulation of regional fat storage to begin to determine how DIET with and without AEX of different intensities affects gene expression to alter body fat distribution. Body composition and fat distribution (DXA and computed tomography), LPL activity, lipolysis, mRNA expression of genes from gluteal and abdominal adipose tissue, and lipoprotein lipids and glucose tolerance will be measured before and after six months of DIET with high-intensity AEX, DIET with low-intensity AEX, or DIET alone in 120 (40 per treatment group) overweight (BMI=2535 kg/m2), postmenopausal women with abdominal obesity (waist circumference greater than 88 cm). The degree of caloric restriction during DIET will be adjusted so that total caloric deficit (about 2800 kcals/wk) will be similar between treatments. Both

AEX groups will expend 400 kcal/wk in exercise energy expenditure and will reduce dietary intake by about 2400 kcal/wk (about 340 kcal/day). Identification of the mechanisms by which DIET with and without AEX of different intensities affects regional uptake and mobilization of triglyceride to alter body fat distribution will have important clinical implications for the development of the most effective treatment to promote the preferential loss of abdominal fat and improve CVD metabolic risk factors in older women with abdominal obesity.

Project Title: EXTRACELLULAR REGULATION OF LIPOPROTEIN LIPASE ACTIVITY Principal Investigator & Institution: Goldberg, Ira J.; Professor of Medicine; Medicine; Columbia University Health Sciences Po Box 49 New York, Ny 10032 Timing: Fiscal Year 2002; Project Start 01-APR-1991; Project End 31-MAR-2005 Summary: Lipoprotein lipase (LpL) is the principal enzyme responsible for hydrolysis of triglyceride in circulating lipoproteins. Changes in LpL activity are a basic mechanism used to modulate uptake of free fatty acids and perhaps fat-soluble vitamins by tissues. Regulation of LpL involves a number of post-secretory processes. By investigating these processes basic biological insights into the interaction of proteins with heparan sulfate proteoglycans (HSPGs) have been obtained. In this renewal, a series of experiments are proposed to understand how LpL is transferred from its sites of synthesis, principally adipocytes and myocytes, to the luminal surface of endothelial cells. Aim 1 is to determine the pathways required for LPL transport across endothelial cell monolayers. We have observed that LpL transcytosis across endothelial monolayers is reduced by RAP, the 39 kDa inhibitor of the LDL receptor related protein and other receptors in this family. In this Aim we will assess the role of these receptors and HSPGs in the transcytosis of normal and mutant LpL. The importance of this pathway and the association of LpL with proteoglycans will also be studied in vivo. Aim 2 proposes to study how LPL interaction with HSPGs regulates HSPG binding. Using these mice and new mice expressing a tethered dimer of mutated LpL, the importance of LpL-HSPG interactions will be studied. Aim 3 will study how the VLDL receptor and other RAPsensitive receptor, and LpL monomizerization participate in the physiological regulation of LPL actions. We will assess the importance of LpL transcytosis pathways in wildtype and heterozygous LpL transcytosis pathways in wild type and heterozygous LpL knockout mice, the role of RAP-sensitive receptors in regulation of LpL activity with feeding/fasting, and modulation of tissue LpL in mice that cannot covert dimeric LpL to inactive monomers. These experiments will provide information about how a secreted protein transfers from the subendothelial space into the bloodstream and the importance of protein dimerization and HSPG binding in this process. Moreover by understanding the regulation of LpL activity, these investigations will may means to change human caloric and vitamin disposal; processes that are often abnormal in humans with lipoprotein disorders and diabetes.

Summary: Graves' ophthalmopathy (GO) is an autoimmune eye disorder closed associated with Graves' hyperthyroidsim. There is convincing experimental evidence that the orbital fibroblast (including the preadipocyte fibroblast subpopulation) is the target cell in GO. However, the autoantigen against which the immune response is directed is unknown. The thyrotropin receptor (TSHr) is a prime candidate to be the orbital autoantigen because its involvement would help to explain the close clinical and laboratory associations between GO and hyperthyroidism. In recent studies, the PI has demonstrated the present of TSHr mRNA and protein in orbital adipose/connective tissues from patients with GO, wile TSHr expression was not apparent in normal orbital tissues. In addition, she showed that orbital preadipocyte fibroblasts, cells lacking fucntional TSHr, can be differentiated in vitro into mature TSHr-bearing adipocytes. These and other findings led to hypothesize that: 1)expression of TSHr in the orbit in GO is linked to the induction of adipogenesis in orbital preadipocyte fibroblasts, and that; 2) the adipocyte TSHr is the orbital autoantigen recognized by orbital-infiltrating lymphocytes in GO. The PI plans to examine these hypotheses using our system of cultured orbital preadipocyte fibroblasts derived from pateints with GO. In specific aim I, she will define the fibroblast-like cells present in the orbit in GO and identify factors that modulate adipogenesis in these cells. Experiments in Aim II are designed to characterize the obital TSHr and to clarify the link between TSHr expression and adipogenesis in the orbi. In Aim III, she will determine whether cloned orbitalinfiltrating lymphocytes from patients with GO recognize TSHr, or other antigens that are processed "naturally" by autologous antigen-presenting cells. The main goal of the research program is to increase understanding of the orbital immune response in GO in order that novel and more specific therapeutic and preventive strategies for this condition might be developed.

LIVER
LIPOPROTEIN
Principal Investigator & Institution: Ginsberg, Henry N.; Professor; Medicine; Columbia University Health Sciences Po Box 49 New York, Ny 10032 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2008 Summary: (provided by applicant): Lipotoxicity involves the excess delivery of fatty acids (FA) to sites other than adipose tissue. In vivo, fatty acids (FA) can arrive at the liver bound to albumin or as components of TG (TG)-enriched remnant lipoproteins (chylomicron and VLDL). In the latter instances, FA can be liberated from remnants by the action of hepatic lipase bound to capillaries in the hepatic vascular bed or released from lysosomes after receptor-mediated internalization of remnant lipoproteins. In addition to exogenously derived FA, increased availability of FA may result form their synthesis in the liver from acetylCoA via lipogenesis. The latter pathway has been linked recently to insulin resistance and hyperinsulinemia. The liver is unique in that it is able to "unload" excess FA in bulk form by assembling and secreting apoBlipoproteins. There are few data, however, concerning the effects of FA from each of the sources described above on the two-step process of apoB-lipoprotein assembly: the first step involves the targeting of nascent apoB across the ER membrane and assembly of a lipid-poor primordial lipoprotein, while the second step involves the bulk addition of core lipid to the primordial particle and the formation of the mature TG-rich apoBlipoprotein. Importantly, it is not known if each of the pathways involved in providing increased FA within the hepatocyte impacts equally on FA synthesis and oxidation, genes involved in TG synthesis, or genes involved in the assembly and secretion of

apoB-lipoproteins. The link between insulin resistance/hyperinsulinemia and increased VLDL secretion is also incompletely defined. In particular, the relative importance of hepatic lipogenesis versus plasma FA uptake by the liver in the increased apoBlipoprotein secretion observed in insulin resistant animal models and humans has not been studied. The experiments proposed in this project are directed at unanswered questions related to FA regulation of apoB-lipoprotein assembly and secretion, including: (1) the effects of plasma albumin-delivered FA on each of the steps in apoBlipoprotein assembly and the expression of genes involved in maintaining hepatic lipid homeostasis; (2) the effects TG-rich remnant-like particle-delivered FA on apoBlipoprotein assembly and gene expression; and (3) the relative importance of insulin resistance/hyperinsulinemia versus increased plasma FA availability in the reaulation of apoB-lipoprotein assemblv and secretion.

Project Title: MUTATIONS
FUNCTIONAL
CHARACTERIZATION-LIPOPROTEIN
LIPASE
Principal Investigator & Institution: Kamboh, M Ilyas.; Professor; Human Genetics; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2003; Project Start 24-JAN-2003; Project End 31-DEC-2006 Summary: (provided by applicant): Lipoprotein lipase (LPL) enzyme plays a pivitol role in lipid metabolism by hydrolyzing triglyceride (TG) rich lipoprotein particles. Many diseases, including coronary heart disease (CHD), atherosclerosis and obesity seem to be directly or indirectly related to abnormalities in LPL function. A Hind lll polymorphism in intron 8 of the LPL gene has been shown to be associated with plasma TG and HDLcholesterol levels and with the risk of CHD. However, the biological mechanism behind this association is unknown. Previous studies have suggested that the intron 8 sequence, which encompasses the Hind lll site as well as intron 9 and non-coding exon 10 of the LPL gene, contain regulatory elements important for LPL transcription and translation. In this proposal we will determine if the nucleotide change in intron 8 by itself is responsible for the effect by disrupting an intronic enhancer element (Aim 1) and what is the role of the 3' region (intron 8, intron 9, exon 10) in regulating LPL transcription (Aim 2). In addition, we have identified a putative insulin response element (IRE) in non-coding exon 10 of the human LPL gene following sequence comparison of LPL genes from various species. The putative IRE sequence was targeted for mutation detection and we identified a 5 bp deletion mutation. We propose to characterize this new mutation further by performing functional and molecular studies (Aim 3). The proposed molecular and functional studies will characterize the functional significance of the LPL Hind lll and exon 10 mutations and may lead to identification and characterization of LPL regulatory elements in intragenic and 3 untranslated region of the gene.

ApoE
20
Lipase
(apolipoprotein E) remains the best-defined genetic risk factor for late onset Alzheimer disease (AD). ApoE is involved in cholesterol transport and, in AD, is associated with Abeta deposits. A number of in vitro and invivo studies have shown that apoE binds to the Abeta peptide, and affects both its clearance and its aggregation. ApoE is cleared by a family of cell surface receptors, members of the low-density lipoprotein (LDL) receptor family. We found expression of these receptors in subsets of cells in the CNS, focusing our attention primarily on the LDL receptor related protein, LRP. Polymorphisms in LRP may also affect the risk of AD, and in vitro, LRP can promote endocytosis of Abeta complexed to LRP ligands. In this proposal, we will continue to focus on endocytosis of apoE and Abeta via this family of receptors, but we will also expand our studies to look at other members of the LDL receptor family, including the VLDL receptor and apoE receptor 2. In addition, we will address newly identified functions of these receptors as signal transduction molecules. For example, in response to ligand binding, these receptors have been shown to affect calcium influx, protein phosphorylation, and glial activation. We propose that the deposition of apoE and related molecules on Abeta deposits in the AD brain affects the function of surrounding neurons and glia via these receptors. These ligand-receptor interactions could help explain the connection between amyloid deposits and formation of phospho-tau positive neurites in the AD brain. Aim 1. We hypothesize that clearance of apoE and lipoprotein-associated molecules interact with the VLDL receptor and apoEr2. A) We will test whether apoE isoforms, apolipoprotein J (apoJ) and lipoprotein lipase (LPL) are cleared by the VLDL receptor or apoEr2. B) We will test whether these receptors, present on microglia and neurons, act as clearance mechanisms for Abeta. C) We will measure the presence of apoJ and LPL in the AD brain, testing whether either affects the processes of amyloid deposition and dystrophic neurite formation. D) We will determine if polymorphisms in these genes may also affect the risk of AD. Aim 2. We hypothesize that the signaling functions of apoEr2 and the VLDL receptor cause neuronal dysfunction seen in AD. A) We will test whether these receptors interact with several hypothesized signal transduction molecules (including disabled) invivo. B) We will test whether these molecules are important for calcium influx and neurite outgrowth in neurons and activation of glia. C) We will test whether these molecules are involved in the phosphorylation of tau observed in neurofibrillary tangles of AD brains.

Project Title: GENES CAUSING SPONTANEOUS OBESITY Principal Investigator & Institution: Warden, Craig H.; Associate Professor; Pediatrics; University of California Davis Sponsored Programs, 118 Everson Hall Davis, Ca 956165200 Timing: Fiscal Year 2002; Project Start 01-JUN-1998; Project End 31-MAY-2003 Summary: The long-term goal of this research is to investigate the mechanisms of spontaneous obesity in mice. Previous work has identified 4 chromosomal regions (mouse chr. 6,7,12,and 15) or loci (QTLs) that contribute to obesity in spontaneously obese BSB mice. BSB mice were produced by a backcross of (Mus spretus x C57BL/6J) F1 x B6. Preliminary data on an available congenic mouse strains confirm that the locus on chr. 7 affects adiposity. The objective of this present proposal is to identify the genes underlying these obesity loci. Congenic mouse strains carrying the spretus chromosomal regions as donor DNA on the B6 background will be created. As co-incident QTLs for obesity, plasma cholesterol and hepatic lipase (HL) activity on mouse chr. 7 were found, the already constructed B6 HL knockout will used to test the hypothesis that alterations of HL activity determine these cholesterol and/obesity loci. BSB backcrosses with the HL KO B6 mouse will yield animals both homozygous and heterozygous for the HL knock-out. QTLs at chromosome 7; will be compared and contrasted in these two groups. The mouse chr. 6,7, and 1 loci include within their 90 percent confidence intervals, respectively, the obese, tubby, and uncoupling protein 2-genes. Molecular and biochemical studies of these candidate genes will be performed to test whether differences are likely to explain the observed effect on the trait. If there are differences in the coding portion of the spretus and B6 leptin, then the biological consequence of the differences will be tested. The chromosome 6 locus was linked to just one of the four fat pads measured in BSB mice. Leptin mRNA levels in the four fat pads will be determined to examine their correlations with plasma leptin and fat pad sizes. They have already found that spretus and B6 UCP2 differ for 2 amino acids, so uncoupling activity of UCP2 from these strains will be examined.

Lipase
Timing: Fiscal Year 2002; Project Start 30-SEP-1994; Project End 31-AUG-2004 Summary: Hepatic lipase is a 476 amino acid glycoprotein that catalyzes phospholipid and triglyceride hydrolysis in circulating lipoproteins. Hepatic lipase activity varies widely among individuals, and this variation has been associated with inter-individual differences in the plasma concentrations of high density lipoproteins (HDL), particularly the HDL2 subfraction, the rates of low density lipoprotein (LDL) synthesis and catabolism, and in the size distribution of LDL. Preliminary data from our laboratory suggest that ethnic differences in hepatic lipase activity may also be responsible for the well known differences in plasma HDL concentrations between African American and white American men. Since these studies are based on correlations between phenotypes, however, they are subject to confounding by secondary factors such as obesity and plasma triglyceride concentrations that may have independent effects on hepatic lipase activity and lipoprotein metabolism. Therefore it is difficult to infer from these studies whether or not the relationship between hepatic lipase activity and plasma lipoprotein concentrations is causal. Thus a key question that remains unanswered by these studies is "does primary variation in hepatic lipase activity cause variation in plasma lipoprotein metabolism in humans?" A second question that remains unanswered is what causes the wide variation in hepatic lipase activity observed in otherwise healthy individuals? These two questions provide the focus of this competing continuation. In the first two Specific Aims, we will compare individuals with genetically defined hepatic lipase activities to determine: i) whether genetic variation in hepatic lipase activity accounts for the well known differences in plasma HDL-C concentrations between African American and white men, and ii) whether primary differences in hepatic lipase activity cause differences in plasma lipoproteins. In the third Specific Aim, we will determine whether genetic polymoprhism in hepatic lipase contributes to the very high hepatic lipase activities commonly seen in white Men. These studies will help to determine the role of variation in hepatic lipase activity in determining plasma HDL concentrations, and LDL size distribution, two important risk factors for coronary artery disease.

Project Title: GENETICS AND REGULATION OF HEPATIC LIPASE Principal Investigator & Institution: Deeb, Samir; Research Professor; Medicine; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 31-AUG-2006 Summary: (provided by applicant): The long-term goals of this proposal are to define mechanisms of regulation of hepatic lipase (HL) levels in humans and to determine how genetic variation at the HL gene locus modulates these levels under a variety of physiological and pathological states. HL plays a key role in lipoprotein metabolism by catalyzing the hydrolysis of triglycerides and phospholipids. A high level of HL is associated with two important metabolic risk factors for atherosclerosis: diminished concentrations of plasma high density lipoprotein cholesterol (HDLC) and an increased prevalence of small, dense low density lipoprotein (LDL) particles. Various studies, including those of our group, have shown that a significant proportion (20-25%) of the variability in HL activity is explained by a common genetic variation in the regulatory sequences of the HL gene, and that ethnic/racial background, gender and intraabdominal fat accumulation are other important modulating factors. The underlying hypotheses of this proposal are: first, that additional variants in the HL gene are responsible for variation in HL activity and the associated lipoprotein profiles in different ethnic/racial groups. Second, that high hepatic lipase activity is a risk for the

development of cardiovascular disease. Third, that transcription factors whose activity is modulated by ligands would be excellent targets for drug design. Fourth, that HL activity is modulated by the commonly used drugs that modulated lipids. Our preliminary results support these hypotheses. The specific aims are to: 1) Identify a small set of genetic markers that would predict levels of HL activity and the associated lipoprotein phenotypes. 2) Define all hepatic lipase gene variants that are associated with risk for cardiovascular disease. 3) Identify and characterize transcription factors that regulate hepatic lipase gene expression. 4) Determine in human subjects the impact of perturbation of lipid metabolism and insulin resistance on HL activity. The results of these studies will provide insights into the metabolic and molecular bases of interindividual variation in HL activity and the associated plasma lipoprotein profiles. Key transcription factors that regulate HL activity could serve as targets for novel pharmaceutical for inducing a favorable lipoprotein profile. The genetic markers would be valuable in predicting cardiovascular risk as well as response to therapy. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Principal Investigator & Institution: Hsueh, Willa A.; Professor of Medicine and Chief; Medicine; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 01-AUG-1999; Project End 31-JUL-2004 Summary: The theme of this investigation is the hypothesis that insulin resistance (IR), hyperinsulinemia and a subset of components of the IR syndrome promote changes in the vasculature leading to atherosclerosis, and that there are common genes linking these factors and coronary artery disease (CAD). We have developed a multidisciplinary approach incorporating gene mapping in animals and in man with human and animal physiologic analyses that involve extensive phenotyping of traits related to IR and atherosclerosis to test this hypothesis, Because of their family structure and the high prevalence of IR, Mexican American (MA) families with CAD represent an ideal ethnic group in which to identify genes linking to both IR and CAD and to determine the critical physiologic relationships of IR and hyperinsulinemia and its associated metabolic changes to vascular structural alterations leading to atherosclerosis. Exciting preliminary data in MA families supports both our hypothesis and the overall feasibility of completing the goals outlined in this grant application. Three experienced teams of senior research investigators and three supportive cores constitute a highly focused, collaborative, integrated investigation that features expertly designed and performed phenotyping; innovative methods of mathematical genetic analysis pioneered and successfully applied by members of our team; state of the art genetic mapping technology through the newly created UCLA Human Genetics Department; and physiologic investigation of the role of hyperinsulinemia and IR in atherosclerosis through novel mechanisms leading to vascular damage including the role of paraoxonase, hepatic lipase and alterations in lipid turnover, as well as lipid oxidation. An important theme of this program project is gene->cell->tissue->animal- >human>gene translation. The combination of detailed human and animal phenotyping, comprehensive genetic mapping, novel tissue investigations and lipid turnover studies outlined herein provides a powerful, multi- dimensional approach to identify genes and pathophysiologic mechanisms linked to atherosclerosis.

Principal Investigator & Institution: Arnett, Donna K.; Associate Professor; Epidemiology; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2002; Project Start 01-SEP-1999; Project End 31-AUG-2004 Summary: The Genetics of Hypertension Associated Treatments (GenHAT) is proposed as a prospective study to examine whether the association between selected hypertensive genes and combined fatal coronary heart disease and nonfatal myocardial infarction in high-risk hypertensives is modified by the type of antihypertensive treatment, leading to differential risks of coronary heart disease (CHD). Such genetreatment interactions might shed important light On the variation in patient response to antihypertensive agents, and improve our ability to pick the right antihypertensive for specific patients. GenHAT will be an ancillary study to ALLHAT (the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial). ALLHAT recruited 42,515 hypertensives and randomized them to one of four antihypertensive agents (lisinopril, chlorthalidone, amlodipine, and doxazosin); followup will be completed in March, 2002. GenHAT will characterize hypertension genetic variants and determine their interaction with antihypertensive treatments in relation to CHD. DNA from frozen clots stored at the ALLHAT Central Laboratory will be used to genotype variants of hypertension genes (angiotensinogen -6, angiotensin converting enzyme insertion/deletion, angiotensin type- 1 receptor, alpha-adducin, beta2 adrenergic receptor, lipoprotein lipase, and 10 new hypertension variants expected to be discovered during the course of the study). In addition to the primary aim, a number of secondary aims will be undertaken to evaluate gene- treatment interactions in relation to other endpoints, including all-cause mortality, stroke, heart failure, left ventricular hypertrophy, decreased renal function, peripheral arterial disease, and blood pressure lowering. Because of the ethnic and gender diversity of ALLHAT, we will also assess effects of these variants on outcomes in key subgroups (age >65 years, women, African Americans, Type II diabetics), and whether the gene-treatment interactions in relation to outcomes are consistent across subgroups. This proposal has the advantages of (1) incorporation into an already funded clinical trial, and (2) collaboration with experienced investigators in genetic analysis (Drs. Boerwinkle and Eckfeldt) and clinical trials (Drs. Davis and Ford). It will, therefore, provide an important and cost-efficient contribution to the knowledge and understanding of the treatment of hypertension.

A-I (apo A-I), Scavenger Receptor class b1 (sr- bi), Hepatic lipase (HL), and Lecithin Cholesterol Acyl Transferase (LCAT). A basic assumption in these studies is that alterations in the expression of genes known to be involved in HDL metabolism will affect the expression of other genes also participating in the metabolism of this lipoprotein. The novel genes identified from these studies will be prioritized for further biological characterization based on a variety of parameters including: level of expression change, clustering of expression patterns between mice of different HDL mutant genotypes, and sequence or expression pattern similarities to other genes known to participate in lipoprotein metabolism. The function of a limited number of novel "HDL candidate" genes (approximately 10) will be assessed each year through their over-expression in transgenic mice coupled with careful analysis of the consequence of transgene over-expression over-expression on lipoprotein metabolism. In these studies we will be utilizing a combination of new technologies and previously developed experimental substrates to address the fundamental question of what genes are directly or indirectly involved in the metabolism of HDL in vivo.

Principal Investigator & Institution: Rader, Daniel J.; Director, Preventive Cardiology; Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2004; Project Start 01-MAR-1996; Project End 31-MAR-2009 Summary: (provided by applicant): Plasma levels of high-density lipoprotein (HDL) cholesterol and its major HDL apolipoprotein, apoA-I, are inversely associated with atherosclerotic cardiovascular disease. Plasma HDL cholesterol and apoA-I levels are determined in part by the rate at which they are catabolized, but the mechanisms that modulate their catabolism in vivo remain incompletely understood. Both acute inflammatory states, such as sepsis, and chronic inflammatory states, such as the metabolic syndrome, are associated with low levels of HDL cholesterol and apoA-I, primarily due to increased catabolism. A major underlying hypothesis of this project has been that extracellular phospholipases are upregulated in response to inflammation and modulate systemic HDL metabolism through hydrolysis of HDL phospholipids. We cloned and characterized a new member of the lipase gene family that we termed endothelial lipase (EL). In the current cycle of this project, we have demonstrated that overexpression of EL in mice causes markedly reduced HDL due to increased catabolism, and antibody inhibition of EL in mice causes increased HDL due to reduced catabolism. In this competing renewal proposal, we will focus our efforts on EL toward achieving a greater understanding of its structure-function relationships, metabolic interactions with other genes that influence HDL, association with atherosclerosis, and its relationship to human physiology and pathophysiology. Specific Aim 1: To investigate the differences between EL and its highly homologous relatives LPL and HL with regard to the molecular basis of the lipid and lipoprotein preferences of EL compared with LPL and HL. Specific Aim 2: To test the hypothesis that in the liver, EL interacts with HL and SR-BI to influence HDL metabolism, selective uptake of cholesterol, and reverse cholesterol transport. Specific Aim 3: To determine the effects of chronic hepatic-specific EL expression on atherogenesis in mice. To compare these results with the effects of endothelial-specific EL expression on atherosclerosis. To test the hypotheses that endothelial EL expression influences endothelial physiology. Specific Aim 4: To test the hypothesis that EL is increased in inflammatory conditions in humans and may contribute to the reduced HDL-C levels associated with these

conditions. A recent editorial stated: "Perhaps the most important questions concerning endothelial lipase are: a) does it play an important role in HDL metabolism in humans, and b) does it play a significant role in atherogenesis?" This proposal addresses both of these issues and also addresses key structure-function questions and potential genegene interactions with regard to EL and its effects on HDL metabolism. The results of these studies should provide important new insight into the role of EL in HDL metabolism and atherogenesis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: HEPATIC METABOLISM OF DIET DERIVED LIPOPROTIENS Principal Investigator & Institution: Cooper, Allen D.; Professor; Palo Alto Medical Foundation Res Inst 795 El Camino Real Palo Alto, Ca 94301 Timing: Fiscal Year 2002; Project Start 01-JUL-1986; Project End 30-NOV-2003 Summary: The overall objective is to understand how chylomicron remnants contribute to atherosclerosis. The goal of the current proposal is to elucidate the mechanisms of the hepatic removal of these particles. Remnants accumulate in the blood during the postprandial period implying that there are times when their removal becomes limiting. The hypothesis to be tested is that the initial rate of chylomicron remnant removal is determined by the number of LDL receptors, and the capacity of the liver to sequester the particles before internalizing them (sequestration space). The size of the sequestration space is defined by heparan-sulfate-proteoglycans, and the affinity of the space for remnants is modified by the presence of hepatic lipase. The steady state rate of removal is determined by transfer from sequestration to LDL receptors and the LRP. The latter, is determined in part, by co-factors, particularly hepatic apoE. Three specific aims are proposed. First, to complete studies utilizing the isolated perfused mouse liver to characterize the remnant removal process. Isolated mouse liver perfusion was validated as a technique for studying remnant removal. Data demonstrates that both the LDL receptor and the LRP are saturable components of this process, and that there may be an additional mechanism for removal; apoE is absolutely required for rapid remnant removal, but the hepatic secretion of apoE is required for only one component of the process. Mice deficient in LDL receptors and the LRP, as well as apoE, will be utilized to complete these studies. Second, methodologies will be developed to determine the size of the sequestration space and the rate of egress from this space. The use of confocal microscopy with fluorescent labeled remnants and fluorescent markers for both endothelial cells and hepatocytes will allow determination of where remnants are accumulating, what fraction of the accumulated remnants are in the space of Disse, and the rate at which they leave this space. A multi-compartment model for analysis of the isotope removal data is being developed to determine the affinities and capacities of the components of the removal process. Using the animals of the third specific aim, this will identify which molecules contribute to these components. As a back up strategy, cell separation techniques can be used to accomplish the goals of the first two methods. The third specific aim will examine the nature of the determinants of the process. Mice that express varying fixed levels of LDL receptors will be used to study the role of this molecule in initial removal, as well as egress from sequestration. A similar strategy will be utilized for the LRP by creating truncated but functional, LRP-like molecule. Mice with different isoforms of apoE will be studied to evaluate how this affects its function as a co- factor, and as a portion of the capture mechanism. This group of studies will also evaluate the role of LPL in remnant removal in the liver. In the last group, the amount, location and enzymatic activity of hepatic lipase in the liver will be varied, to learn whether it serves as a co-factor for the LRP, or whether it serves as a determinant

for the sequestration space, or both. In addition, attempts will be made to vary the syndecan content of the liver to test the role of this HSPG as a major determinant of the sequestration space. Together, it is anticipated that these studies will provide a concrete model for remnant removal, as well as identify the key elements in this mechanism, at which therapeutic intervention might be directed.

It also includes study of the influence of mutations and polymorphisms in key genes involved in HDL metabolism with the objective of identifying genomic determinants of HDL speciation and the genetic basis of HDL deficiency disorders. Specific Aims: 1) To complete the isolation and characterization of the native molecular species of human HDL using selected affinity immunosorption. The stoichiometry of constituent proteins and lipids in those species will be established by immunochemical methods and mass spectroscopic analysis. 2) To continue to isolate novel proteins from human HDL and elucidate their gene structures. Candidates are proteins discovered by mass spectroscopic analysis that are not present in sequence databases. 3) To characterize the HDL species that are substrates and products of SR-Bl, -hepatic lipase (HL), phospholipid transfer protein (PLTP), and - mediated reactions. 4) To develop methods for quantitative measurement of individual HDL species in plasma. 5) To study the composition and distribution of plasma HDL species of HDL deficient subjects. 6) To determine the impact of mutations andpolymorphisms in the HL, PLTP, SR-BI, the ABCA1 transporter, and apolipoprotein L genes on the metabolism of individual molecular species of HDL.

The particular focus of Project 3 is on following up significant evidence of linkage and association that has been detected in the current grant period. Two chromosomal regions will be the primary targets of this effort, a region on chromosome 2 that has shown linkage to a quantitative trait locus (QTL) for leptin levels (LOD=7.5) and association between leptin levels and polymorphisms in the pro-opiomelanocortin gene (p<0.005) and a region on chromosome 15 that has shown linkage to a QTL for a variety of HDL size phenotypes (LODs 2.1 to 3.8) and association between these traits and a variant in the promoter region of the hepatic lipase gene (p<0.001). The previously detected associations with
28
Lipase
strong candidate genes in these two regions will be exploited to focus the initial search on polymorphism in or near these genes. To identify single nucleotide polymorphism (SAPS) in these genes, 20 kb in and around pro-opiomelanocortin and hepatic lipase will be sequenced in 48 individuals from the families that show linkage to these regions and associations with previously typed markers in these genes. All SAPS will be genotyped that have a frequency of at least 5% in the set of 500 individuals in 10 large polymorphism will be initially assessed using combined linkage/disequilibrium and conditional measured genotype methods. When all polymorphism in a given region have been genotype in the 10 large pedigrees, newly developed statistical functional gnomic methods will be applied that are designed to identify functional polymorphism by teasing apart variants which affect the trait from those in linkage disequilibrium with them. SAPS showing evidence of association will be typed in a second set of 500 individuals for replication. Finally, Project 3 will also genotype 50 micro satellite markers in new regions of interest identified by Projects 1 and 2 for purposes of finemapping as well as 20 SAPS in positional candidate genes in these new regions.

Highest exposures occur in children and in minorities. Infants and children appear especially susceptible to disruptors, because of their disproportionately heavy exposures and the vulnerability of their still forming organs to any disruption of the hormonal signaling that irreversibly shapes early development. Yet little is known, either of children's pathways of exposure, or of the human developmental toxicity of EDs. To address these gaps, the Mount Sinai Center for Children's Environmental Health and Disease Prevention Research proposes, 1) to characterize the levels and sources of children's exposures to contemporary-use EDs in the urban built environment; 2) to study relationships between EDs and neurobehavioral development; 3) to study relationships among ED exposures, diet, physical activity, and somatic growth; 4) to characterize previously unexplored enzymatic polymorphisms that may modulate individual susceptibility to EDs; and 5) to develop and deploy culturally appropriate, evidence-based strategies in East Harlem to improve children's diets, increase physical activity, reduce obesity, reduce ED exposures, and promote good health. Project 1, the Community-based Prevention Research Project (CBPR), Growing Up Healthy in East Harlem, is built on a longstanding partnership with the East Harlem community. It will study levels and sources of urban children's exposures to EDs and assess relationships among ED exposures, diet, physical activity, obesity, and use of personal care products. Project 2, an ongoing prospective epidemiological study, will analyze new and previously banked biological samples to examine associations between pre- and postnatal exposures to EDs and growth and development in a cohort study of urban children. This project will also continue to assess the developmental effects in this cohort of early exposures to neurotoxicants-organophosphates, pyrethroids, PCBs, and lead-that have been its focus for the past 5 years. Project 3, a molecular genetic study, will assess gene-environment

interactions that may influence individual susceptibility to EDs by identifying and characterizing polymorphisms and variations in expression levels of PON1, lipase, and UGT-glucuronyltransferase enzymes involved in ED metabolism. A new Community Outreach and Translation Core (COTC) will use scientific information from the Center to educate and empower community leaders in East Harlem and to inform policy makers and health professionals regionally and nationally about links between the urban environment and children's health. The Center will contain an Exposure Assessment Core that collaborates with the laboratories of the Center for Disease Control and Prevention (CDC) National Center for Environmental Health, a Biostatistics and Data Management Core and an Administration Core. The Center will support two new investigators in children's environmental research. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: LIPID BINDING PROTEINS IN OBESITY/DIABETES SYNDROMES Principal Investigator & Institution: Bernlohr, David A.; Professor and Head; Biochem/Mole Biol/Biophysics; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2002; Project Start 12-AUG-1998; Project End 30-JUN-2006 Summary: (provided by applicant): In the United States, one in every three individuals is considered very overweight or obese. More than a cosmetic issue, obesity is a positive correlate to cardiovascular disease, hypertension, atherosclerosis and diabetes. The discovery of leptin as an adipocyte-derived secreted cytokine has expanded our view of the fat cell beyond being a repository for caloric excess to a dynamic cell type functioning in the assessment and integration of overall energy homeostasis. The focus of the laboratory is on the linkage between obesity, fatty acid metabolism and lipolysis with an emphasis on fatty acid trafficking in the adipocyte and NIDDM. The laboratory studies fatty acid carriers of the adipocyte, specifically the products of the FABP4 and FABP5 genes. In fat cells, these proteins form 1:1 non-covalent complexes with fatty acids and other hydrophobic monoacyl lipids. aP2 (FABP4) and KLBP (FABP5) each form a physical complex with the hormone-sensitive lipase (HSL), the key rate-limiting enzyme of lipolysis that hydrolyzes triacylglycerol to fatty acids. Consistent with the association of aP2 with the HSL, FABP4 null mice exhibit reduced basal and hormonestimulated lipolysis suggesting fatty acid binding proteins affect the process by removing end-product fatty acids from the lipase reaction and facilitating their efflux from the cell. FABP4 null mice exhibit protection from obesity-linked insulin resistance without reduction in fat mass or leptin levels. Double FABP4-FABP5 null mice have lower fat mass and leptin levels. Conversely, transgenic mice that overexpress KLBP in fat cells under the aP2 promoter, have elevated fat cell mass and are more insulin resistant than are wild type animals. We hypothesize that FABPs stimulate lipolysis via interaction with HSL and that the disruption of the interaction results in a quantitative difference in both the molecular species and abundance of fatty acids that are lipolyzed from the fat cell. Such changes in lipolysis-derived fatty acids affect the availability of fatty acids linked to the development of insulin resistance. To test this hypothesis we propose to: Specific Aim A: Evaluate lipolysis in vivo and in situ from low and high fat fed mice harboring either disrupted FABP genes or the aP2-KLBP transgene. Correlate the rate and extent of lipolysis to insulin resistance in such animal models. Specific Aim B: Examine the physical interaction of FABPs with HSL in vitro. Assess the role of FABPs in regulating the activity of HSL and map the interaction domains of the two proteins. Specific Aim C: Assess the association of FABPs with HSL in 293 cells and 3T3-

Project Title: LIPID SIGNAL TRANSDUCTION /OSCILLATORY INSULIN SECRETION Principal Investigator & Institution: Corkey, Barbara E.; Professor; Boston Medical Center Gambro Bldg, 2Nd Fl, 660 Harrison Ave, Ste a Boston, Ma 02118 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2005 Summary: (provided by applicant): Insulin secretion oscillates, possibly due to oscillatory metabolism of glycolysis, mitochondrial energy production, anaplerosis and lipolysis. These oscillations generate important signals underlying oscillations in electrical activity, ion fluxes and, ultimately, secretion. We hypothesize that FFA may participate as coupling factors to synchronize islet metabolic signal transduction and insulin secretion and to provide communication between peripheral fat cells and islets. This may be achieved by recruiting beta cells, increasing synchrony among beta cells or enhancing responsiveness of beta-cells to glucose. We further presume that FFA and their release by hormone sensitive lipase (HSL) generate important signals that regulate insulin secretion in response to fuel stimuli and elevation of cAMP. We predict that animal models deficient in PFK-M (phosphofructokinase-M) or HSL will demonstrate the critical importance of glycolytic and lipolytic pathways in insulin secretion. Aim 1 will determine the effect of FFA on glucose-induced mitochondrial metabolic oscillations of individual cells within the intact islet. The role of endogenous FFA as a signaling molecule will be studied by monitoring the synchronized metabolic activity in the intact HSL deficient islet. Aim 2 will determine the relationship between oscillatory changes in lipid partitioning and lipolysis in beta cells and islets and GSIS and the effect of FFA on these parameters. Intracellular distribution and movement in real time of fluorescent FFA will be monitored using confocal imaging of beta cells and islets. In addition FFA and glycerol release from stimulated cells will be temporally correlated with insulin secretion and measurements made in Aim 1. Aim 3 will test the hypothesis that FFA promote secretion via direct modulation of voltage-gated L-type calcium channels. Aim 4 will test the hypothesis that oscillatory FFA release from fat cells via HSL-mediated lipolysis plays a role in synchronized insulin secretion from islets. Sequential co-perifusion of isolated fat cells and pancreatic islets will be undertaken. Aim 5 will test the hypothesis that regulation of HSL in the R-cell occurs via oscillatory inhibition by long chain-CoA. Aim 6 will study the mechanism whereby HSL-deficiency in beta-cell results in altered GSIS. Aim 7 will test mechanisms of secretory and electrical synchronization in the intact perfused pancreas and its relationship to islet and single cell studies.

Project Title: LIPOLYTIC MECHANISMS OF PPAR ACTIVATION Principal Investigator & Institution: Plutzky, Jorge; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2004; Project Start 01-JAN-2004; Project End 31-DEC-2007 Summary: (provided by applicant): Peroxisome Proliferator-Activated Receptors (PPARs) are ligand-activated nuclear receptors central to the transcriptional regulation of adipogenesis, glucose control and lipid metabolism. More recent work establishes PPAR expression and effects in the vasculature, including endothelial cells (EC). Despite
Studies
31
these advances, major unresolved issues persist. One central unanswered question in the PPAR field is the nature of endogenous PPAR ligands, which might recapitulate the effects of synthetic PPAR agonists, or how such natural mediators are produced under physiologic conditions. Similarly, despite extensive studies implicating PPARs in lipid biology, little data exists regarding the links between pathways of lipid metabolism and subsequent PPAR activation. Such insight could have major implications for metabolic disorders and atherosclerosis. Data is presented establishing lipoprotein lipase (LPL), the central enzyme in triglyceride-rich lipoprotein metabolism, as an endogenous mechanism for PPARalpha activation. In vitro and in vivo evidence, using both gain of function (LPL overexpression) and loss of function (PPARalpha-deficiency) models, support this claim. LPL-mediated PPAR-alpha activation is independent of LPL's known non-enzymatic effects and is selective as to PPAR (PPARalpha>>PPARdelta> PPARgamma), lipoprotein substrate (VLDL>>LDL>HDL), and lipase- absent with other fatty acid-releasing lipases tested. Furthermore, monoacylglycerol (MAG), a LPLspecific product, is identified as a novel PPARalpha activator contributing to these LPL responses. Our central hypothesis is that lipolysis is a major pathway for endogenous PPAR activation, with distal effects determined by the varying nature of lipoprotein substrate, lipase, and targeted PPAR. This proposal outlines experiments to define lipolytic mechanisms for PPAR activation across these same parameters. Unique contributors to LPL-mediated PPARalpha activation, as suggested by preliminary data, will be studied, including MAG as a little studied signaling molecule and mechanisms of ligand delivery. Key lipolytic variables of lipoprotein substrate and other tiglyceride lipases will be examined in terms of their PPARalpha, -delta, and -gamma effects. These studies include measures of lipolytic PPAR responses on available well-characterized VLDL and plasma samples from both mice and humans. The existence of genetic LPL variants in mouse models and in humans, which have a range of LPL activity, will be utilized in vitro and in vivo to determine how graded LPL function alters wellestablished PPAR responses. These LPL models include the otherwise lethal LPLdeficient mice rescued by transient LPL expression. Through these programmatic efforts, insight will be gained into lipolysis as a mechanism for selective endogenous PPAR activation, and its distal transcriptional effects.

Project Title: LIPOPROTEIN LIPASE AND PREECLAMPSIA Principal Investigator & Institution: Hubel, Carl A.; Assistant Professor of Ob/Gyn; Magee-Women's Health Corporation 204 Craft Ave Pittsburgh, Pa 152133180 Timing: Fiscal Year 2002; Project Start 15-FEB-2000; Project End 31-JAN-2005 Summary: Preeclampsia is a leading cause of maternal death and increases perinatal death five-fold. There is compelling evidence that maternal endothelial dysfunction contributes to the pathogenesis of preeclampsia. Hypertriglyceridemia, decreases in high density lipoprotein (HDL) cholesterol, and abnormally small-sized low density lipoprotein (LDL) particles are characteristic features of preeclampsia. We have proposed that these lipid abnormalities promote endothelial dysfunction in preeclampsia through the generation of oxidative stress. Lipoprotein lipase (LPL) plays a vital role in the clearance of triglycerides from the circulation. The importance of LPL defects in the development of cardiovascular disease is increasingly recognized. Several common variations in the LPL gene promote the triad of increased triglyceride, decreased HDL cholesterol, and small-sized LDL. The dyslipidemic effects of these functional variants are accentuated by pregnancy. In our Caucasian population, a sum total of 18.8% of preeclamptics are heterozygous for either the N291S or D9N coding

Lipase
sequence variants of the LPL gene, compared with 4.6% of normal pregnancy controls. Accordingly, Aim 1 is to test whether these observations can be generalized to other populations. We will compare the prevalence of the four most common, functional variants in the LPL gene in Caucasians and African-Americans from western Pennsylvania, and in Icelandic women. Aim 2 is to sequence the coding and promoter regions of the LPL gene to identify other functional variants, which will then be genotyped in cases and controls. We posit that variations in the LPL gene the predispose to dyslipidemia are over-represented in women with preeclampsia. Aim 3 is to compare plasma lipids, lipid peroxidation products, and markers of endothelial dysfunction in women with preeclampsia stratified by genotype. We hypothesize that, among women with preeclampsia, those carrying LPL variants with reduced enzymatic activity will display an especially adverse blood profile. In Aim 4, we will measure plasma LPL enzyme activity in women 12 weeks postpartum to further test the hypothesis that a constitutional deficiency in LPL (hormonally and/or genetically mediated) is associated with preeclampsia. In Aim 5, we will explore the effects of heterozygous LPL deficiency on endothelial regulation of vascular function during pregnancy, using the LPL knockout mouse. This systematic approach will help to clarify the link between dyslipidemia and the pathogenesis of preeclampsia and could provide clues to prevention or treatment of the disorder.

Project Title: LIPOPROTEIN LIPASE, NUTRITION AND NERVE MYELINATION Principal Investigator & Institution: Eckel, Robert H.; Professor of Medicine,; Medicine; University of Colorado Hlth Sciences Ctr P.O. Box 6508, Grants and Contracts Aurora, Co 800450508 Timing: Fiscal Year 2002; Project Start 01-JAN-1990; Project End 30-NOV-2003 Summary: Lipoprotein lipase (LPL) is a hydrolytic enzyme which releases fatty acids and monoacylglyerol from nutrient-dependent triglyceride-rich lipoproteins [chylomicrons and very low density lipoproteins (VLDL)] and regulates the partitioning of these lipid fuels to tissues. This process has been studied most extensively in adipose tissue and muscle. However, LPL is also made in other sites including the nervous system, where the lipase is found in the brain, spinal cord and peripheral nerve. In the peripheral nerve, in vitro experiments have suggested, but not yet proven, that function of LPL is to enhance the uptake of chylomicron and VLDL triglyceride fatty acids to Schwann cells for myelin phospholipid synthesis. The studies outlined in this proposal will further this understanding by: 1) determining the sites of LPL expression within the peripheral nerve and defining the role of LPL in myelin synthesis nd peripheral nerve regeneration; 2) assessing the expression and regulation of peripheral nerve LPL in animal models of diabetic peripheral neuropathy; and 3) evaluating the efficacy of retroand adenovirally mediated human LPL (hLPL) gene delivery to augment myelination following peripheral nerve injury, and reverse and/or retard the neuropathy of diabetes mellitus. A combination of experiments in rodents and cultured Schwann cells will be utilized. To more specifically determine the role of the LPL in peripheral nerve in rodents (Specific Aim #1), the cells of origin and response of LPL to crush injury will be examined in normal rats and mice, and in transgenic mice without LPL in the peripheral nerve. In Specific Aim #2, several models of diabetic mellitus with already characterize peripheral neuropathy will determine if LPL expression in the peripheral nerve injury is impaired +/- crush injury. Finally, in Specific Aim #3, an important series of experiments will determine the efficacy of the delivery of LPL to augment myelination in regenerating nerves and in rodents with diabetic peripheral neuropathy. Two viral

gene delivery systems will be evaluated for their ability to deliver hLPL to rat sciatic nerve: retrovirus-mediated gene delivery, which targets dividing cells, and adenovirusmediated gene delivery, which introduces genes into non-dividing cells. The method that better facilitates sciatic nerve recovery from crush injury will then be administered to rodent models of diabetic neuropathy in an attempt to improve peripheral nerve myelination. Overall, these studies should provide a comprehensive understanding of the role of LPL in the peripheral nerve. Moreover, we are hopeful that new insights into the treatment of peripheral neuropathies will also ensue. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

RECEPTOR,
BINDING
Principal Investigator & Institution: Bradley, William A.; Professor of Medicine; Medicine; University of Alabama at Birmingham Uab Station Birmingham, Al 35294 Timing: Fiscal Year 2002; Project Start 01-FEB-2000; Project End 31-JAN-2005 Summary: ApoB is essential to life yet excess apoB100 or apoB48 is atherogenic and associated with increased risk of cardiovascular disease. We identified and cloned a new, unique receptor (R) for dietary triglyceride-rich lipoproteins (TGRLP), the apoB48 R. It is constitutively expressed on monocyte-macrophages (MM), including human atherosclerotic foam cells and bone marrow precursors, and endothelial cells (ECs), cells intimately involved in hemostasis and atherothrombogenesis as well as hemopoiesis, immune function and tissue nutrition. Although we have documented that the apoB48 R binds to apoB48, major questions remain on the precise mechanism(s) of binding and why normal VLDL and LDL have low affinity for this R--which microdomain of apoB48 is necessary for R binding and how the other apoB regions, apoproteins, and lipid constituents modulate binding of lipoproteins to this R. Our published and preliminary data support the hypotheses that (1) an apoB48 microdomain that is required for binding is at or near the lipoprotein lipase binding site, is not releaseable by trypsin, is not in a heparin binding domain, and is masked in normal VLDL and LDL; (2) apoB48 R binding affinity is greater in large particles (Sf greater than 100) than in small particles (Sf less than 100); and (3) apoE inhibits binding to the apoB48 R. This ensures sufficient uptake of larger nutrient-rich (lipids and lipid-soluble vitamins) dietary particles by cells responsible for tissue nutrition, immune function and hemopoiesis, cells with high nutritional requirements, and directs smaller apoB lipoproteins to the liver, as observed in vivo. We propose multiple approaches to define the R-binding apoB48 microdomain (Aim 1) and to define modulators of this interaction (Aim 2), using native, modified, and model lipoproteins, monoclonal antibodies, C-terminal truncated apoB, molecularly engineered apoB mutant constructs, and cell and ligand blotting studies. Knowledge of the basic biochemical determinants and molecular mechanisms that govern the interactions of TGRLP with the apoB48 R are crucial to meaningful intervention to prevent excess, atherothrombogenic uptake by this route while preserving sufficient nutrient uptake or, conversely, to enhance uptake in subjects with multiple pathologies due to defective or deficient apoB.

Lipase
Timing: Fiscal Year 2002; Project Start 01-APR-2000; Project End 31-MAR-2004 Summary: (Adapted from the Investigator's Abstract) Methylmercury (MeHg) is a significant environmental contaminant that continues to pose a great risk to human health. Considerable attention in the scientific and health policy fora is focused on the question of whether MeHg intake from a diet high in fish is associated with aberrant CNS function. A number of recent studies (Kjellstrom et al., 1986, 1989; McKeon-Eyssen et al., 1983; Grandjean et al., 1997) suggest that fetal exposure at levels attained by mothers eating fish regularly during pregnancy are associated with neurological deficits in their offspring. Astrocytes play a key role in MeHg-induced excitotoxicity. [1] MeHg preferentially accumulates in astrocytes. [2] MeHg potently and specifically inhibits glutamate uptake in astrocytes. [3] Neuronal function is secondary to disturbances in astrocytes. [4] co-application of nontoxic concentrations of mercury and glutamate leads to the typical appearance of neuronal lesions associated with excitotoxic stimulation. [5] MeHg induces swelling in astrocytes. These observations are fully consistent with MeHg-induced dysregulation of excitatory amino acid homeostasis, and indicate that a glutamate-mediated excitotoxic mechanism is involved. The working hypotheses of the proposal outline a number of critical target sites for MeHg-induced neurotoxicity. In Specific Aim 1.0 we will test the hypothesis that activation of the astrocyte-specific enzyme, cytosolic phospholipase A2 (cPLA2) and the ensuing hydrolysis and release of arachidonic acid (AA) are mediators of glutamate release upon exposure to MeHg. We will investigate the lipase(s) involved, and determine the relationship between cPLA2 activation, regulatory volume decrease (RVD), and glutamate release. In specific Aim 2.0, we will test the hypothesis that MeHg-induced increased extracellular glutamate concentrations will competitively inhibit cystine transport into astrocytes, leading to diminished supply of cysteine for neuronal glutathione (GSH) synthesis. In Specific Aim 3.0, we will test the hypothesis that modification of cysteine residues by MeHg is associated with altered glutamate transport, and that it is regulated by the chemical redox-state of reactive cysteine residues in the astrocyte-specific glutamate transporters, GLAST and GLT1. The studies will be carried out in rat primary cultures of neurons and astrocytes, as well as Chinese hamster ovary (CHO-K1) cells (where transporters can be over expressed in cells that lack the endogenous glutamate transporter). Our approach will encompass a broad array of methods, including molecular biology, electrophysiology, radiolabel trans-membrane fluxes, and electrical impedance measurements of cell volume.

Project Title: MEMBRANE STRUCTURE AND ENZYME ACTIVITY Principal Investigator & Institution: Brockman, Howard L.; Professor; Hormel Institute; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2002; Project Start 01-MAR-1992; Project End 31-MAY-2006 Summary: (provided by applicant): Translocation of proteins to phospholipid membranes involves specific protein structures and can be triggered by the presence in the interface of a non-phospholipid lipid "second messenger," like diacylglycerol The long-range goal of this research is to understand how interactions between phospholipids and non-phospholipid second messengers regulate peripheral protein binding to interfaces and the subsequent expression of catalytic activity. Its focus is pancreatic triacylglycerol lipase (PTL) and its cofactor protein, colipase (COL), for which lipids like diacylglycerols are activators as well as lipase substrates. PTL and two other members of its gene family, lipoprotein lipase and hepatic lipase, are the primary regulators of the distribution of lipids to and from peripheral tissues. Hence, they are

35
highly relevant targets in the treatment of diseases of lipid homeostasis like obesity and atherosclerosis. To function properly, the lipid-binding motif of the N-terminal domain of PTL must bind to the lipid-water interface in its catalytically-efficient or 'open' conformation. The role of the C-terminal domain of PTL in this is unclear. In the fluid lipid interfaces at which PTL functions, phospholipids and lipase substrates form dynamic complexes that mix with uncomplexed lipids. We hypothesize that complexes inhibit the rate of protein adsorption and, hence, lipolysis. We further hypothesize that once PTL and COL bind, they rearrange lipid species in the interface to help overcome the inhibition. Apolipoprotein C-II, the cofactor for lipoprotein lipase, appears to act similarly to COL despite its lack of structural homology. To test these hypotheses, we propose 1) to define the role of lipid complexes in regulating the association of PTL's domains and COL to interfaces. To accomplish this we will use radiometric and fluorometric methods to measure initial rates of COL and PTL domain binding as a function of interfacial composition and packing; 2) to determine the ability of each of the three lipid associating motifs of PTL and COL to perturb lipid lateral organization. To accomplish this we will fluorimetrically determine the extent to which each bound protein motif is able to laterally redistribute lipid species in interfaces; 3) to determine the interfacial requirements for the binding of PTL's catalytic domain in the catalyticallyefficient conformation. To accomplish this we will chemically and spectroscopically determine how PTL catalytic domain binding and conformation are regulated; 4) to define the functional similarities of the PTL-COL lipolytic system with the serum lipoprotein lipase-apolipoprotein C-II system. To accomplish this the techniques used in aims 1-3 will be applied to these proteins. With its unique focus on the role of lipid interfacial structure in regulating protein binding, this research will provide a specific mechanistic understanding of how cofactor proteins enable lipolysis to occur at physiologically relevant interfaces. More broadly, it will help to explain how lipid second messengers regulate protein translocation associated with signaling events in cells.

Project Title: MENOPAUSE, LPL GENOTYPE AND METABOLISM AFTER WEIGHT LOSS Principal Investigator & Institution: Goldberg, Andrew P.; Professor; Medicine; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002; Project Start 01-SEP-2000; Project End 31-JUL-2005 Summary: This research is designed to determine whether obese postmenopausal women with a common polymorphism in the lipoprotein lipase (LPL) PvuII gene, i.e. the (+) allele have less favorable metabolic responses to weight loss (WL) treatment than women without the LPL PvuII cut-site (-/-). The hypothesis is that the LPL PvuII genotype affects fasting muscle and adipose tissue and LPL activity and the metabolic responses to hypocaloric feeding-induced WL in a dose-dependent manner to affect the magnitude of the reduction of total and visceral fat, and improvements in glucose/insulin and lipoprotein lipid metabolism following WL in postmenopausal women. Specific aims determine whether obese women who are homozygous for the LPL PvuII (+) cut-site, i.e. the (+/+) genotype, have greater increases in adipose tissue LPL and decreases in muscle LPL activity and larger decreases in resting metabolic rate (RMR) and fat oxidation than heterozygotes during hypocaloric diets, that are associated with: 1) the loss of less total body and visceral fat; and 2) smaller improvements in lipid and glucose metabolism than women without the cut-site, i.e., (/-). We will study healthy, obese (Body Mass Index, 30-40 kg/m2) 50-60 year old

Lipase
women within 5 years of menopause. The statistical power to test our hypothesis is based on preliminary data showing differences in adipose tissue LPL responses to WL between LPL PvuII (+/+) and (-/-) genotypes, and requires 27 women/genotype. Subjects will be entered prospectively based on their LPL genotype to ensure a homogeneous group of obese menopausal women are studied to eliminate confounding factors of gender, age, duration from menopause and body composition on the metabolic responses to WL treatment. Metabolic studies are performed on prepared calculated weight maintaining eucaloric diets for 2-3 weeks at baseline and after 6-mo WL to ensure metabolic stability, and on hypocaloric diets after the short-term study to assess metabolic responses to negative energy balance. We will measure muscle and adipose tissue LPL activity, RMR, fat oxidation, total and visceral body fat (DXA and CT scans) lipoprotein lipids and. glucose/insulin responses during an oral glucose tolerance test. Following the post-WL metabolic evaluations, subjects enter a 6- mo follow-up period followed by metabolic testing to assess long- term metabolic adaptations and weight regain by genotype. Collectively, these findings will enhance our understanding of obesity by assessing the gene-metabolic mechanisms underlying the predisposition of some obese women to more favorable metabolic health benefits from WL. This would allow the targeting of WL treatments to women more likely to respond, and pharmacologic and other treatments to those less likely to respond to WL. This optimistic outcome would reduce prevalence of obesity and risk for CVD in older women. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: METABOLIC REGULATION OF LIPOPROTEIN LIPASE IN ADIPOCYTES Principal Investigator & Institution: Currie, Richard A.; Scientific Review Administrator; Wheeler Institute for Biomedical Res Jhu Bayview, Alpha Center Baltimore, Md 21224 Timing: Fiscal Year 2002; Project Start 01-MAR-1993; Project End 31-JUL-2003 Summary: (adapted from the applicant's abstract): In this application Dr. Currie plans to extend studies from the previous funding period on the role and mode of action of Nuclear Factor Y (NF-Y) in the transcriptional regulation of the lipoprotein lipase (LPL) gene during adipocyte differentiation. Five hypotheses are proposed: 1) Reiterated AThook motifs in HMG-I(Y) both bind AT-rich DNA sequences as well as stabilize the CCAAT-box complex; 2)Reversible phosphorylation of PC4 regulates the stability of NFY subunit interaction, and indirectly the CCAAT-box complex; 3)HMG-I(Y) and PC4 provide functional links between NF-Y, Oct-1 and components of the Pol II complex in the assembly of the pre-initiation complex; 4)The NF-Y complex is associated with additional, currently unidentified protein which modulate transactivation potential; and 5) The histone acetyltransferases GCN5 and P/CAF remodel the chromatin around the LPL promoter CCAAT-box through their interaction with NF-Y. In order to eventually test these hypotheses, three specific aims will be pursued: I) The functional roles of PC4, HMG-I(Y), GCN5, and P/CAF in modulation NF-Y mediated transcription will be studied. II) Additional NF-Y subunit associated components will be identified and purified and their functional properties in the native NF-Y complex studied. III) An in vitro cell-free transcription system based on purified components will be established in order to study the biochemical roles of NF-Y, Oct-1, and their associated cofactors in the transcriptional regulation of the human LPL gene.

Project Title: METABOLISM OF INTRAVENOUS LIPID EMULSIONS Principal Investigator & Institution: Deckelbaum, Richard J.; Director, Professor of Pediatrics; Institute of Human Nutrition; Columbia University Health Sciences Po Box 49 New York, Ny 10032 Timing: Fiscal Year 2003; Project Start 30-SEP-1992; Project End 31-AUG-2007 Summary: (provided by applicant): Our objective is to characterize pathways whereby intravenous (IV) lipid emulsions, commonly used clinically as nutritional support, deliver specific types of triglyceride (TG) to tissues and cells. With increasing recognition of the importance of omega-3 (omega-3) very long chain fatty acids (FA) (omega3-VLC FA) in multiple biological pathways, our major goal is to delineate mechanisms for delivery of these omega3 FA to different tissues, and to define the effects of this delivery on selected cellular endpoints related to cell TG and cholesterol metabolism. Recent evidence indicates that routes for blood clearance and tissue uptake of fish oil omega3 TG are very different from those of omega6 soy oil long chain TG (LCT). For example, removal of (omega3 VLCT) emulsions from blood seems to depend far less on intravascular lipolysis than does LCT emulsions. While substantial amounts of both emulsions are delivered to tissues as intact TG, this pathway is likely more important for omega3 TG particles. Omega3 TG particles are less dependent on "classical" lipoprotein receptor related clearance pathways, than are LCT. FA derived from omega3 TG appear to act as stronger inhibitors than LCT in sterol regulatory element (SRE) dependent gene expression-genes that are involved in both TG and cholesterol syntheses. The proposed research will systematically define mechanisms whereby TG composition, particle size, and specific ligand related pathways contribute to LCT vs. omega3-VLCT clearance and metabolism in different tissues and cell types. Aim 1 will use physical-chemical approaches (e.g., 13C-NMR) to clarify how omega3-TG and FA affect the properties of the emulsion particle surface, and how this in turn affects lipoprotein lipase and apoprotein E binding, structure, and function. Aim 2 utilizes in vitro cell culture experiments and Aim 3 in vivo mouse models to differentiate metabolic pathways for omega3-VLCT/FA and omega6 TG/FA, and how these differences affect expression of genes related to TG and cholesterol homeostasis. Studies in Aim 4 will test if hypotheses generated from cell and mouse models are likely to occur in humans -- by protocols whereby omega3-VLCT and LCT emulsions are infused in healthy volunteers. Our analyses will differentiate between mechanisms for clearance and metabolism omega3 vs. omega6 TG and FA. Our studies will allow new insight as to how fish oil derived emulsions reach different tissue, undergo metabolic processing, and regulate expression of certain genes, and will also provide carefully characterized models for the study of human lipid and lipoprotein metabolism.

Project Title: MOBILIZATION OF TRIACYLGLYCEROL STORES IN INSECTS Principal Investigator & Institution: Arrese, Estela L.; Biochem and Molecular Biology; Oklahoma State University Stillwater Stillwater, Ok 74078 Timing: Fiscal Year 2002; Project Start 01-FEB-2002; Project End 31-JAN-2007 Summary: (provided by the applicant): Unlike vertebrates, where the stored fatty acids are mobilized as free fatty acids, a great number of insects, mobilizes fatty acids as an-1, 2-diacylglycerol (DG). The mobilization of TG stores requires the action of a TG-lipase, whose activity is hormonally regulated. The substrate of the lipase (TG) is found in large intracellular lipid droplets, which are constituted by a core of TG surrounded by a complex surface layer of phospholipids and proteins. On the other hand, the TG-lipase

Lipase
localizes in the cytosol of lipolytically unstimulated fat body cells. Lipolysis involves the interaction of the lipase with the surface of the lipid droplet. It is known that activation of lipolysis promotes both an increase of intracellular calcium concentration and activation of amp-dependent protein kinase (A-kinase) but the basic mechanisms involved in how phosphorylation-dephosphorylation reactions modulate the rate of lipolysis is unknown. Moreover, little is known about the relevance and nature of the structural and compositional changes that affect the lipid droplet when lipolysis is hormonally activated. These changes must ultimately affect the interaction of the lipase with the lipid substrate and the concomitant activation of lipolysis. DG moves from the lipid droplet to the plasma membrane by an uncharacterized mechanism. It appears that after the conversion of TG into DG on the surface of the lipid droplets, DG would be transferred to a cytosolic carrier, which in turn would target the delivery of DG across the plasma membrane. The overall goals of this project are to establish the mechanisms regulating lipolysis by determining the factors that promotes the interaction between TG-lipase and its substrate, the lipid droplet and to define the mechanism of intracellular transport of DG. Clearly the elucidation of these mechanisms is of fundamental importance in insect biochemistry and physiology. These studies will provide comprehensive information on the lipolytic process in insects and this knowledge could also contribute to the broad field of lipid metabolism and transport in vertebrates.

Project Title: MODIFICATION OF HELICOBACTER PYLORI LIPID A Principal Investigator & Institution: Trent, Michael S.; Microbiology; East Tennessee State University Box 70565 Johnson City, Tn 37601 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2005 Summary: (provided by applicant): The outer membrane of Gram-negative bacteria consists of a unique molecule known as lipid A that serves as the membrane anchor for lipopolysaccharide (LPS). Lipid A (endotoxin) is the component of LPS responsible for the stimulation of the host innate immune system involved in Gram- negative sepsis. The lipid A of Escherchia coli is a hexa-acylated disaccharide of glucosamine that is substituted at the 1- and 4'- positions with phosphate and glycosylated at the 6' position with two Kdo (3-deoxy-D-manno-octulosonic acid) moieties. Nine enzymes are required for biosynthesis of Kdo2- lipid A, the minimal LPS required for E. coli growth under normal laboratory conditions. Since lipid A is required for bacterial growth, it has become an interesting target for the design of novel antibacterial agents. Although single copies of the lipid A biosynthetic genes are found in nearly all Gram-negative bacterial genomes including those of Helicobacter pylori, the lipid A of the latter is underacylated with the phosphate groups either absent or modified. The primary focus of the present study is the identification of novel enzymes required for the modification of H. plyori lipid A and initial studies to evaluate the importance of such modifications during infection. Secondly, the lipid A structure of Helicobacter heilmannii will be investigated. H. pylori is now considered the causative agent of gastric and duodenal ulcers and H. heilmannii has recently been found associated with human gastritis. The specific aims of the current proposal are: (I) characterization and cloning of lipid A deacylases of H. pylori; (II) characterization and cloning of genes required for modification of the phosphates of H. pylori lipid A; (III) relevance of H. pylori lipid A modifications during infection; and (IV) isolation, purification, and structural characterization of key lipid A species of H. heilmannii. The completion of these aims will not only further the understanding of the lipid A biosynthetic pathway in H. pylori

Principal Investigator & Institution: Kolattukudy, Pappachan E.; Professor and Directpr; None; University of Central Florida 12443 Research Pky, Ste 207 Orlando, Fl 328283252 Timing: Fiscal Year 2003; Project Start 30-SEP-1993; Project End 31-DEC-2007 Summary: (provided by applicant): Tuberculosis remains the leading cause of preventable deaths. Natural spread of multidrug resistant tuberculosis and the potential use of such strains by terrorists make discovery of new targets for antimycobacterial therapy a very critical need. Cell wall lipids constitute a major physical and chemical defensive barrier that helps the pathogen evade the host defenses and antimycobacterial drugs. Therefore, synthesis of such unique lipids that are critical for infection can be suitable targets for new antimycobacterial drugs. Multiple methyl branched lipids such as dimycocerosyl phthiocerol (DIM) have been shown to be virulence factors. Elucidation of the biochemical reactions and the nature of the enzymes involved in the biosynthesis of such virulence factors is required for developing novel drags. To this end we propose to: 1. Elucidate the functions of lipase genes and their possible role in pathogenesis, a) Express and characterize the catalytic capabilities of lip gene products and determine whether disruption of specific lip genes will result in the absence of a specific class of acyl-lipids or absence of a specific group of esterified fatty acids, and determine whether the mutations affect virulence, b) Directly test whether the expressed lip gene products can release the acyl chains from the expressed synthases in vitro. 2. Elucidate the biological function of tes genes and their possible role in virulence, a) Express tes genes and characterize the catalytic capabilities of their products, b). Disrupt the three tes genes, determine the effects on lipid metabolism by using 14C-labeled acetate and 14C-labeled propionate as radiotracers and determine the effect of the mutations on virulence of the pathogen in the murine model. 3. Elucidate the function of wes genes, a) Express the wes genes and test whether these gene products are involved in the esterification of the methyl branched acids generated by the large synthases to the hydroxyl groups in the ultimate acceptors, b) Determine the consequences of disrupting the wes genes on lipid metabolism and test the virulence of mutants that show novel biochemical phenotypes. 4. a) Elucidate the role of the novel ( subunit in the enzyme that catalyzes the synthesis of methylmalonyl-CoA, the building block for the multiple methyl branched virulence factors, b) Determine whether disruption of accD4 and accD5 affect propionyl-CoA carboxylation, and methyl branched lipid synthesis in M. tuberculosis and its virulence. c) Determine the possible role of succinate as a source for methylmalonyl-CoA. The results of this study are likely to give information and tools for screening chemical libraries to discover new types of drug candidates directed at novel targets in M. tuberculosis and thus help in combating multidrug resistant tuberculosis.

Timing: Fiscal Year 2002; Project Start 01-JUL-1984; Project End 31-DEC-2005 Summary: The theme of this proposal is the examination of altered states of triglyceride metabolism contributing to coronary artery disease. The program addresses this theme using the mouse and human homology at the pathological, physiological, biochemical, genomic and molecular levels. Of the 5 projects in this proposal, Projects 3 will mostly involve studies in mice while 2 projects principally involve studies in humans, with 5 cores providing phenotyping, genotyping, sequencing, positional cloning, biostatistical and administrative support. Our major approach will be use genetic defects in mice and humans to identify underlying genes that contribute to altered states of triglyceride metabolism. We will emphasize familial combined hyperlipidemia (FCHL), a genetically complex disease characterized by increased plasma triglyceride metabolism. We will emphasize familial combined hyperlipidemia (FCHL), a genetically complex disease characterized by increased plasma triglyceride and/or cholesterol levels which accounts for up to 20% of premature coronary artery disease. Dr. Lusis' project will extend previous genetic studies in mice to systematically delineate genetic factors contributing to triglyceride metabolisms. Notably, will combine forces with Dr. Peltonen's Project to identify the gene affected by Hyplip1, a mutation in the mouse that causes combined hyperlipidemia and co- localizes with a homologous FCHL locus in humans. Dr. Wong's Project will focus on the structure-function properties of lipoprotein lipase (LPL), an enzyme central to triglyceride metabolism, as well as identifying genetic loci that affect LPL expression and may contribute to the LPL deficiency observed in FCHL. Dr. Reve's Project will isolate the genes, and characterize the function of the corresponding gene products, for two mouse mutations affecting triglyceride metabolism, fatty liver dystrophy (fld) and combined lipase deficiency (cld); these mutations are characterized by insulin resistance (fld) and LPL deficiency (cld) that often associated with FCHL. Dr. Rotter's project will use a combination of genome wide linkage and candidate gene association approaches to characterize genetic risk factors for coronary artery disease in human populations by identifying genes for lipid and lipoprotein variation in FCHL. Dr. Peltonen's project, using the power of a discrete population isolate (the Finn's) will perform fine mapping of a recently identified FCHL locus to isolate the predisposing FCHL gene by a positional cloning approach. Importantly, the Finnish FCHL locus is syntenic with mouse Hyplip1, and Project V will assist in isolating the mouse gene to complement and aid in the identification of the homologous human FCHL gene. Thus, the 5 projects provide a coordinated approach to identifying major genes affecting triglyceride metabolism and predisposing to coronary artery disease.

Summary: Marijuana is the most widespread illegal drug of abuse in Western societies. The main active ingredient of marijuana, Delta9- tetrahydrocannabinol (THC), binds to selective G protein-coupled receptors, called cannabinoid receptors. Activation of these receptors by THC exerts profound behavioral effects in humans. This suggests that endogenous neurotransmitter substances that engage cannabinoid receptors may serve important physiological and pathological functions. Although an endogenous cannabinoid ligand, anandamide, was recently identified, evidence indicates that additional ligands may exist. On the basis of our preliminary results, we propose to test the hypothesis that 2- arachidonylglycerol (2-AG), a product of phospholipid metabolism, constitutes a second endogenous ligand for brain cannabinoid receptors. To test this hypothesis it will be necessary to show that the enzymatic machinery for the formation and inactivation of 2-AG is present in neurons. Moreover, it will be necessary to demonstrate that 2-AG binds to and activates neuronal cannabinoid receptors. The first aim of the proposed research is to investigate the mechanisms responsible for 2-AG production, using rat brain neurons in primary culture. Preliminary experiments have shown that these neurons produce substantial amounts of 2-AG. The proposed studies will identify the transmembrane signalling systems and enzyme pathways underlying 2AG production. The second aim of our proposed research is to determine whether neural activity is necessary for the formation of 2-AG. Preliminary experiments have demonstrated that, in superfused slices of rat hippocampus, high-frequency electrical stimulation of an identified excitatory pathway (the Schaffer collaterals) results in the marked accumulation of 2-AG. We will examine whether 2-AG formation is stimulated by levels of neural activity that are likely to occur in vivo, and investigate the ion channels and neurotransmitter receptors involved in this response. The third aim of our proposal is to characterize the pharmacological properties of 2-AG in cortical neurons in culture. Initial experiments have indicated that 2-AG activates neuronal cannabinoid receptors. We will determine the potency, efficacy and selectivity of 2-AG in eliciting such response. The fourth aim of the proposed research is to identify the biochemical mechanisms involved in the biological inactivation of 2-AG. Preliminary results suggest that 2-AG is hydrolyzed enzymatically to arachidonate and glycerol, two products that do not activate cannabinoid receptors. We will use subcellular fractions of rat brain tissue to identify and characterize the enzyme activity that mediates 2-AG hydrolysis. In conclusion, by demonstrating that 2-AG meets the necessary criteria of an endogenous cannabinoid ligand, our studies will shed new light on the mechanisms of marijuana abuse and help develop new strategies in the treatment of neurological, psychiatric and substance abuse disorders.

Project Title: NOVEL PROTEASE FORMULATION BASED ON CROSSLINKED CRYSTALS Principal Investigator & Institution: Shenoy, Bhami C.; Altus Biologics, Inc. 625 Putnam Ave Cambridge, Ma 021394807 Timing: Fiscal Year 2003; Project Start 01-JUL-2000; Project End 31-MAR-2005 Summary: (provided by applicant): Design of stable and efficient formulation of proteins for therapeutic use as drugs has been a major focus of biotechnology and pharmaceutical companies. In the Phase I grant, we developed a stable, active formulation of protease from Aspergillus melleus, TheraCLEC-Protease, for use in the treatment of chronic abdominal pain in chronic pancreatitis and also along with TheraCLEC-Lipase and amylase for the treatment of malabsorption as a result of pancreatic insufficiency in cystic fibrosis and chronic pancreatitis. TheraCLEC-Protease

exhibited product characteristics superior to commercially available pancreatic enzyme products. TheraCLEC-Protease exhibited a very high level of activity against casein and stability under low pH and towards various proteases present in the intestine. Moreover, in the preliminary investigations, the TheraCLEC-Protease did not show any toxicity. Based on these results in Phase II, we will prepare a drug product prototype for use in the treatment of abdominal pain in chronic pancreatitis and along with TheraCLEC-Lipase for use in the treatment of pancreatic insufficiency, azotorrhea and steatorrhea in cystic fibrosis and chronic pancreatitis patients. As a first step, we will crystallize and crosslink the protease with methods developed in Phase I Subsequently, we will mix TheraCLEC-Protease with TheraCLEC-Lipase and amylase for use in a final formulation or alone depending on the disease and type of treatment. The final formulation will be tested for efficacy in digesting proteins and fats in dogs with ligated pancreatic ducts. Using radiolabeled TheraCLEC-Protease, we will follow the lack of absorption into the systemic circulation. In addition, we will test the subacute, subchronic and long-term effects of feeding TheraCLEC-Protease in two species. If successful, a TheraCLEC-Protease prototype will provide an efficient treatment for abdominal pain. TheraCLEC-Protease will be ready to enter clinical trials, and will provide a novel treatment for pancreatic insufficiency in chronic pancreatitis and cystic fibrosis along with TheraCLECLipase.

Principal Investigator & Institution: Tontonoz, Peter J.; Associate Professor; Pathology; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 01-FEB-2001; Project End 31-JAN-2006 Summary: The long-term goal is to understand the mechanisms by which lipids regulate gene expression in vascular cells and thereby influence the development cardiovascular disease. The interaction of oxidized low-density lipoprotein with cells of the artery wall is central to the pathogenesis of atherosclerosis. Oxidized lipids not only serve as the substrate for macrophage lipid accumulation, but are also thought to contribute to lesion development through regulation of adhesion molecules and cytokines. This proposal is focused on defining the role of the nuclear receptor PPARgamma in regulating macrophage gene expression and function in response to oxidized lipids. PPARgamma is expressed at high levels in macrophage-derived foam cells of atherosclerotic lesions and is transcriptionally activated by oxidized fatty acid components of oxLDL. Multiple functions have been proposed for this receptor in macrophages, including promotion of cell differentiation, modulation of cytokine expression, and regulation of lipid uptake and metabolism. However, the true role of this transcription factor in macrophage physiology and vascular disease remains unclear. The first aim is to identify target genes of PPARgamma in monocytic cells. The identity of these genes should provide valuable insight into the nature of the processes controlled by this receptor. Preliminary data has identified the nuclear oxysterol receptor LXRa and lipoprotein lipase as regulatory targets for PPARgamma. The second aim is to characterize gene expression and function in genetically defined macrophages that over express or lack PPARgamma. The importance of PPARgamma in regulating lipid metabolism, cytokine production and mediating the biological effects of oxidized lipids on macrophage gene expression will be tested. The third aim is to analyze the role of PPARgamma in macrophage function and atherogenesis in vivo through creation of a macrophage-specific deletion of the

PPARgamma gene. These aims are expected not only to advance our understanding of the biologic function of PPARgamma but also to clarify mechanisms by which lipid mediators regulate gene expression during pathologic processes such as inflammation and atherosclerosis.

Project Title: ORGANOPHOSPHORUS PESTICIDE TOXICOLOGY Principal Investigator & Institution: Casida, John E.; Professor of Entomology; Environmntl Sci Policy & Mgmt; University of California Berkeley Berkeley, Ca 947205940 Timing: Fiscal Year 2003; Project Start 01-DEC-1997; Project End 30-JUN-2007 Summary: (provided by applicant): Organophosphorus (OP) insecticides are the principal cause of pesticide-related human poisonings. Recent restrictions on the use of chlorpyrifos and diazinon reflect continuing concern for human health, particularly children. The two principal targets of OP toxicant action are acetylcholinesterase (AChE) for acute toxicity and neuropathy target esterase (NTE) for OP-induced delayed neuropathy (OPIDN). This research focuses on noncholinergic effects, based in part on findings with collaborators on nullizygous AChE-knockout mice (AChE -/-) and heterozygous NTE-knockout mice (NTE ). AChE -/- mice are extremely sensitive to chlorpyrifos oxen (CPO) (intraperitoneal LD50 0.45 mg/kg) compared with their wildtype littermates (LD30 3 mg/kg), establishing the importance of an unidentified nonAChE target for acute lethality. The first specific aim is to identify this non-AChE target in mammals. Mouse brain proteins from AChE -/- and wild-type mice will be radiolabeled in vitro and ex vivo with [3H-ethyl]CPO. Differential protein labeling in the AChE -/- and wild-type mice with very low levels of [3H]CPO will allow selection, purification and identification of the candidate alternate target of OP acute poisoning. The second aim is to establish the function of NTE in OPIDN using mice as the model. The NTE mice have a 40% reduction in NTE activity, making them ideal for toxicological investigations. The studies will focus on the association of NTE levels with behavioral and neuropathological changes, the sensitivity of NTE and wild-type mice to ethyl octylphosphonofluoridate and other OP delayed toxicants, validation of the mouse model for OPIDN and the mechanism by which lowered NTE induces hyperactivity and delayed toxicity. The third aim is to define the mechanisms of toxicity from disruption of signal transduction pathways, and more specifically those mediated by lysophospholipase, diacylglycerol lipase, and the muscarinic acetylcholine receptor. The last goal is to define the mechanisms and significance of two secondary targets of OP pesticides: altered endocannabinoid action by OP phosphorylation at a nucleophilic site coupled to the cannabinoid receptor-1 (CB1) agonist site; kynurenine formamidase (KFase) structure and function relative to teratogenesis and diazinon oxen action in the brain. Knowledge gained on OP pesticide toxicology is also applicable to OP nerve gases as chemical warfare and terrorism agents.

Project Title: PERILIPIIN AND LIPOLYSIS Principal Investigator & Institution: Greenberg, Andrew S.; None; Tufts University Boston Boston, Ma 02111 Timing: Fiscal Year 2004; Project Start 15-JAN-1999; Project End 31-MAR-2008 Summary: (provided by applicant): Adipocyte lipolysis contributes significantly to the pathogenesis of obesity-associated diseases by increasing levels of circulating free fatty acids (FFA). FFA promote insulin resistance and type 2 diabetes. My laboratory's longterm goal is to elucidate molecular mechanisms of lipolysis regulation. The proposed studies will investigate structure / function relationships of Perilipin A (Peri A), a lipid droplet- associated phosphoprotein that regulates lipolysis mediated by hormone sensitive lipase (HSL) and non-HSL lipase(s). Peri A acts dually as a suppressor of basal lipolysis (in the absence of hormonal stimulation) and as a potent enhancer of protein kinase A (PKA)-stimulated lipolysis (in the presence of hormonal stimulation). Despite its important regulatory role, the primary sequences and the mechanism(s) by which Peri A regulates lipase actions have not been determined. Our preliminary studies indicate that Perilipin regulates lipolysis via multiple regulatory domains, which exhibit surprising lipase specificity. The proposed studies will 1) identify the minimal domains of Peri A that modulate basal and PKA-stimulated lipolysis by HSL and non-HSL lipase(s), 2) determine the relative role of PKA phosphorylation sites in PKA- stimulated lipolysis by HSL and non-HSL lipase, and 3) define the in vivo effects of altered Peri A expression, Peri A truncations and Peri A PKA site mutants using Peri A transgenic and Peri null mice. Our adipocyte and systemic studies will measure basal lipolysis, lipolytic response to beta-adrenergic agents, and antilipolytic response to insulin. These studies will provide in vivo proof of concept tests of how Peri A expression levels, regulatory domains, and phosphorylation sites regulate basal and stimulated lipolysis. These data will be directed to the prevention and treatment of diabetes, hyperlipidemia and other obesity - associated disorders. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: PERILIPINS AND CELLULAR TRIACYLGLYCEROL METABOLISM Principal Investigator & Institution: Brasaemle, Dawn L.; Nutritional Sciences; Rutgers the St Univ of Nj New Brunswick Asb Iii New Brunswick, Nj 08901 Timing: Fiscal Year 2002; Project Start 15-AUG-2000; Project End 31-JUL-2004 Summary: (Adapted from the Investigator's Abstract): Obesity is a health problem that is reaching epidemic proportions in the United States and has become a major and growing factor contributing to an increased prevalence of Type II diabetes and an increased risk of premature death from cardiovascular disease. Despite the need for therapeutic options to control obesity, little is known about the intracellular mechanisms that regulate fat storage and release in adipose tissue. Fatty acids, the body's major energy currency, are stored as triacylglycerols in large intracellular lipid droplets in adipocytes. The perilipins are the most abundant proteins on the surfaces of lipid droplets in adipocytes and are also found in steroidogenic cells. The proposed studies test the hypotheses that 1) perilipins facilitate triacylglycerol storage by forming a protective barrier against cytosolic lipases, and 2) phosphorylation of perilipins facilitates lipolysis in lipolytically stimulated adipocytes by attenuating the barrier to facilitate lipase access to stored triacylglycerols. The Specific Aims of the proposed research are to 1) define the structural domains of perilipin A required for its targeting

These aims will be tested by the expression of intact and mutant perilipin A in cultured cells that lack perilipins followed by assays for lipid storage and release, and the presence of the mutant perilipins on lipid droplets.

Project Title: PHARMACOGENETICS OF THE STATIN RESPONSE Principal Investigator & Institution: Schaefer, Ernst J.; Professor; None; Tufts University Boston Boston, Ma 02111 Timing: Fiscal Year 2003; Project Start 29-SEP-2003; Project End 31-AUG-2007 Summary: (provided by applicant): Coronary heart disease (CHD) is the leading cause of death and disability in our society. Most CHD deaths occur in subjects over 70 years of age. Significant independent CHD risk factors are age, gender, elevated low density lipoprotein (LDL) cholesterol (C), decreased high density lipoprotein (HDL) C, hypertension, smoking, diabetes, elevated lipoprotein (a) or Lp(a) (LDL C> 50% reduction), and elevated C-reactive protein. In this response to RFA HL-03-001 (ancillary pharmacogenetic studies), we propose to study 2804 male and 3000 female participants in the Prospective Study of Pravastatin in the Elderly at Risk (PROSPER), who were selected for age 70-82 years, having vascular disease coronary, cerebral or peripheral) or increased CHD risk due to smoking, hypertension or diabetes and total cholesterol levels between 4.0 and 9.0 mml/L or 151 and 340 mg/dl. In this randomized controlled trial pravastatin decreased LDL C 34% and triglyceride 12% and raised HDL C 5%. Creactive protein and Lp(a) values have already been measured. Fatal and nonfatal myocardial infarction (MI) were decreased by 19%, and fatal MI 24%, but increased risk of new cancer were noted in the pravastatin group over 3.2 years as compared to the placebo group (all p<0.01) (Lancet 360: 1623-30, 2002). Benefit was greatest in subjects with low HDL C (<1.1 lmml/L or 43 mg/dl). No benefit of pravastatin versus placebo on cognitive function or stroke was noted. We and others have shown that statins increase large alpha 1 migrating apolipoprotein A-I containing HDL, decrease plasma lathosterol, a marker of cholesterol synthesis, and increase plasma betasitosterol, a marker of cholesterol absorption as well as decrease cholesterol ester transfer protein (CETP) mass. We propose to measure HDL subspecies, CETP mass, lathosterol, and beta-sitosterol in the 292 subjects who developed CHD while on pravastatin and in a control group (n=292) who did not develop CHD on pravastatin. We propose to isolate DNA in all subjects, carry out sequencing for single nucleotide polymorphism detection in 5 male and 5 female hyper-responders and the same number of hypo-responders (LDL C <10% reduction) and then genotyping at all SNPs on the two 292 patients groups, and the informative SNP detection on the entire 5804 cohort at the following gene loci: ATP binding cassette transporters G5 and G8 (ABCG5, ABCG8), CETP; HMG CoA reductase, apolipoprotein E, lipoprotein and hepatic lipase, microsomal transfer protein, C-reactive protein, connexin, plasminogen activator type I inhibitor and stromelysin I. These genes have been selected because of our own preliminary studies, and their known key role in cholesterol absorption and lipoprotein metabolism or CHD. We hypothesize that response to pravastatin in terms of lowering of LDL C, triglycerides and C-reactive protein, and HDL C raising will be related to specific genotypes and haplotypes. We also hypothesize that subjects with the greatest LDL Cand C-reactive protein-lowering, the greatest increase in large alpha HDL particles, the greatest reduction in lathosterol and the least increase in beta-sitosterol will have the

greatest benefit in CHD risk reduction, and that these changes will be related to specific genotypes and haplotypes of the candidate genes being examined. These results can be used to formulate guidelines for identifying elderly subjects for statin treatment to prevent future CHD. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Principal Investigator & Institution: Michaeli, Tamar H.; Developmtl & Molecular Biology; Yeshiva University 500 W 185Th St New York, Ny 10033 Timing: Fiscal Year 2003; Project Start 15-MAR-2003; Project End 31-DEC-2006 Summary: (provided by applicant): The objective of the proposed research is to elucidate the contribution of the camp phosphodiesterase, PDE7A, to the regulation of glucose homeostasis. Since cAMP antagonizes insulin action, cAMP phosphodiesterases can augment insulin signaling by reducing levels of cAMP pools relevant to insulin action. In particular, PDE3B augments insulin signaling in fat and liver. PDE3B, however, is not expressed in skeletal muscle. Our studies established PDE7A as a cAMP specific phosphodiesterase expressed to high levels in skeletal muscle as the particulate PDE7A2 splice variant. Our targeted disruption of the PDE7A gene in mice yielded PDE7KO mice with defects in glucose homeostasis - glucose intolerance and insulin resistance. PDE7KO mice, however, are not hyperinsulinemic and their insulin secretion in response to injected glucose is indistinguishable from that of wild type mice. Consistent with the abundant expression of PDE7A2 in skeletal muscle, and with the strong contribution of skeletal muscle to whole body glucose disposal, PDE7KO mice are impaired in insulin stimulated glucose uptake by skeletal muscle, but not by adipose tissue. Based on these observations, we hypothesize that a primary defect in PDE7KO mice is the disposal of glucose by skeletal muscle. The experimental program will examine in vivo defects of PDE7KO mice in glucose disposal, glucose and lipid metabolism, cAMP and insulin signaling, in skeletal muscle, and in liver and adipocytes. The contribution of pancreatic beta-cells to PDE7KO phenotypes will also be assessed. Thus, the aim of the proposal is to at understand the cross talk between the insulin and the cAMP signaling pathways and mechanisms underlying diabetogenic, metabolic perturbations in glucose homeostasis.

Project Title: PHOSPHOLIPID SYNTHESIS BY GIARDIA LAMBLIA Principal Investigator & Institution: Das, Siddhartha; Associate Professor; University of Texas El Paso El Paso, Tx 79968 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 31-MAY-2007 Summary: (provided by applicant): The ancient protist, Giardia lamblia colonizes the small intestine of humans and animals. This protozoan parasite lacks mitochondria, highly evolved Golgi structures, and other organelles typical of higher eukaryotes. Nonetheless, it has developed unique metabolic pathways that allow this parasite to survive and multiply in the small intestine by scavenging lipid molecules from the host. Various investigators have shown that Giardia trophozoites are unable to synthesize the majority of their own lipids and cholesterol de novo; rather, they depend mostly on supplies from outside sources. Naturally, the questions of how they scavenge and utilize exogenous lipids for metabolic purposes are extremely important. Earlier we have shown that exogenous phospholipids, once internalized, can be remodeled via

deacylation/reacylation and headgroup exchange reactions, which allow Giardia to alter lipids and generate parasite-specific phospho and glycophospholipid molecules. In addition, recent results from our laboratory suggest that transbilayer/ cellular movement of fluorescent-conjugated sphingolipids is dependent on actin filaments and the microtubule network, suggesting the presence of sophisticated lipid transport machinery in Giardia. The major goal of this proposal is to investigate the underlying mechanisms of lipid transport and metabolism in this early-diverging protozoan cell. Therefore, the specific aims are: Aim-1 to investigate the transbilayer lipid transport and trafficking, and the possible role of giardial actin/microtubule cytoskeleton in these processes; Aim-2 to investigate and characterize the regulatory enzyme(s) of phospholipid deacylation/reacylation reactions (i.e., phospholipase/lysophospholipase) by molecular/biochemical methodologies; Aim-3 to study the key enzymes of headgroup exchange pathways, and finally Aim-4 to test the effects of various inhibitors/analogs of lipid metabolic enzymes on in vitro growth of this water-borne pathogen. These studies will yield valuable information regarding lipid synthesis/remodeling by mucosal protozoa, and will lay the foundation for future investigations on novel chemotherapies against Giardia and other related protozoan parasites.

Project Title: PLEIOTROPIC EFFECTS ON OBESITY AND LIPOPROTEINS Principal Investigator & Institution: Comuzzie, Anthony G.; Associate Scientist; Southwest Foundation for Biomedical Res San Antonio, Tx 782450549 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2008 Summary: Obesity is an important risk factor for atherosclerosis. However, the reasons for the relationship between these disorders are still poorly understood. Evidence from body composition studies suggests that adiposity is highly correlated with several important endocrine measures including phenotypes related to glucose and lipoprotein metabolism. Little is known regarding the genes that influence adiposity and their pleiotropic effects on these endocrine parameters and on correlated risk factors for atherosclerosis such as lipoprotein phenotypes. In this Project, we will measure several adiposity-related phenotypes including total body fat (estimated using bioimpedance), and serum concentrations of several adipocyte derived endocrine factors (e.g., leptin, adiponectin, acylation stimulating protein, and TNFalpha) in pedigreed baboons. To better examine the underlying genetic determinants of variable gene expression, we will also continue to measure quantitative mRNA levels of several candidate genes (the leptin, lipoprotein lipase, and glucose transporter 4 genes) as well as three additional genes (the leptin receptor, adiponectin, and resistin genes) in biopsied omental fat tissue. We will detect and localize quantitative trait loci (QTLs) influencing adiposityrelated phenotypes and test hypotheses regarding their pleiotropic effects on lipoprotein traits and genotype ? age interaction. Localization of quantitative trait loci will be accomplished via a genomic screen using candidate gene and STR polymorphisms in a single pedigree of 750 non-inbred baboons. Statistical linkage analyses will be performed using the multipoint variance component method which makes efficient use of all available information and which we have extended to accommodate the complications of inbred pedigrees. When a quantitative trait locus is found, we will utilize multivariate linkage analysis to determine if adiposity-related genes have pleiotropic effects on lipoprotein phenotypes. Finally we will attempt to identify strong positional candidate genes in the regions of promising QTLs and will use combined linkage/disequilibrium analyses and a novel Bayesian quantitative trait nucleotide

Project Title: POLYMORPHISMS OF B1 AND B2 RECEPTOR GENES AND OBESITY Principal Investigator & Institution: Lima, John J.; Professor; Nemours Children's Clinic 807 Children's Way Jacksonville, Fl 322078482 Timing: Fiscal Year 2002; Project Start 15-JUN-2001; Project End 31-MAY-2004 Summary: Obesity has been associated with insulin resistance, hyperinsulinemia, noninsulin-dependent diabetes mellitus, hypertension and a higher risk of cardiovascular disease and death. Genetic, metabolic and environmental factors are known to contribute to obesity. Genes that are involved in the regulation of catecholamine function may be important because of the role catecholamines play in energy expenditure and lipolysis. Ninety percent of fat in the body is stored in white adipose tissue as triglycerides, which are broken to free fatty acids and glycerol through the action of hormone-sensitive lipase. Lipolysis is stimulated by beta1, beta2 and beta3 adrenergic receptors in human adipocytes, with the beta1 and beta2 adrenergic receptors (beta1 and beta2 AR) being the most dominant subtypes. Catecholaminestimulated lipolysis is reduced in obesity, which is thought to be due to defects in the beta2 AR-signaling pathway. Mis-sense mutations in the beta1 AR gene results in polymorphisms at nucleic acid 145 (A->G), which results in a substitution of Ser for Gly at position 49, and at nucleic acid 1165 (G- >C, which results in a substitution of Gly for Arg and position 389. Beta1 AR polymorphisms have functional significance; whether or not they associate with obesity is unknown. Mutations in the 5' leader and coding regions of the human beta2 AR gene give rise to several polymorphisms, which can after receptor density and function. The working hypotheses of this submission are that polymorphisms at position 389 and haplotypes of beta2 AR polymorphisms in the 5' leader and coding regions associate with obesity. Specific Aim #1: to compare the beta1 AR allele frequencies and genotypes in healthy obese and non- obese subjects. The hypothesis driving this specific aim is that obesity associates with the Gly 389 beta1 AR allele. Specific Aims #2: to compare the distribution of beta2 AR haplotypes in healthy obese (Body Mass Indexes > 30) and non-obese (BMI < 25) subjects. Beta2 AR haplotypes will be determined by PCR and direct sequencing. The thesis driving this specific aim is that obesity associates with the Arg19-Gly16- Glu27 beta2 AR haplotype. The distribution of beta2 AR haplotypes in 118 non-obese and 118 otherwise healthy obese subjects will be compared. The results of this study will determine whether polymorphisms in beta1 and beta2 AR allels associate with obesity. The information obtained from our studies are important in designing clinical trials of interventions designed to reduce body weight.

Project Title: POSTPRANDIAL VITAMIN A Principal Investigator & Institution: Blaner, William S.; Professor; Medicine; Columbia University Health Sciences Po Box 49 New York, Ny 10032 Timing: Fiscal Year 2004; Project Start 01-AUG-2004; Project End 30-JUN-2009 Summary: (provided by applicant): Dietary vitamin A is absorbed in the intestine where it is converted to retinyl ester. This retinyl ester is packaged along with other dietary lipids into nascent chylomicrons and secreted into the lymphatic system. Upon entering

49
the general circulation the chyiomicrons undergo metabolism that gives dse to chylomicron remnants that are cleared from the circulation by liver and other tissues. Approximately 66-75% of chylomicron remnant retinyl ester is taken up by the liver where it is either resecreted into the circulation as retinol bound to retinol-binding protein (RBP) or stored in hepatic stellate cells. The remaining postprandial vitamin A is cleared by extrahepatic tissues. At present, there is only very limited understanding of the biochemistry that underlies the uptake and processing of postprandial vitamin A, either by the liver or by other tissues. Our studies will provide new biochemical understanding of these processes. We are proposing to identify factors and to investigate mechanisms responsible for the uptake and processing of postprandial vitamin A within the liver and in extrahepatic tissues, especially focusing on heart and mammary tissue. All of our studies will be carried out in knockout and transgenic mice. In Aim 1, we propose to investigate how chylomicron remnant retinyl ester is taken up by hepatocytes and how the newly absorbed vitamin A is transferred from hepatocytes to hepatic stellate cells for storage. We will investigate the roles that RBP and cellular retinol-binding protein, type I (CRBPI) have in this process. Uptake of postprandial vitamin A into the heart will be examined in Aim 2. Unlike the liver, the heart does not store vitamin A. However, the heart has a relatively high need for retinoic acid for maintaining cellular health. In Aim 2, we will examine the roles that RBP and cellular retinol-binding protein, type III (CRBPIII) have in facilitating cardiac retinoic acid synthesis from postprandial vitamin A and in retinol resecretion from the heart. In Aim 3 we plan to explore how postprandial vitamin A is taken up and processed by mammary tissue for incorporation into milk. Our preliminary data indicate that postprandial vitamin A is an important source of the vitamin A present in milk. Here, we will focus on the roles that RBP, CRBPI, CRBPIII and lipoprotein lipase have in facilitating postprandial vitamin A incorporation into milk.

Principal Investigator & Institution: Johnson, Julia A.; St. Luke's-Roosevelt Inst for Hlth Scis New York, Ny 10019 Timing: Fiscal Year 2003; Project Start 01-FEB-2003; Project End 30-NOV-2005 Summary: (provided by applicant): The candidate for this Research Career Award (K01) plans through this application to receive additional training in conducting animal and clinical research, with a special emphasis in learning cell and molecular biology techniques commonly employed in studying adipocyte biology. Her ultimate goal is to attain independent funding to continue her research in adipose tissue metabolism and development as it relates to obesity and the metabolic syndrome. The New York Obesity Research Center is well-equipped to offer her further instruction and training in these areas. Thiazolidinediones, drugs commonly used in the treatment of type 2 diabetes mellitus, improve insulin sensitivity and hyperlipidemia partly through inducing repartitioning of lipid towards adipose tissue storage. These drugs are ligands for the transcription factor peroxisome proliferator activated receptor gamma (PPAR gamma), which is a regulator of adipocyte differentiation. Weight gain is a common side effect of these drugs, but it is unclear which individuals are most susceptible to gaining weight during treatment. These PPAR gamma agonists also have been shown to redistribute adipose tissue from visceral to subcutaneous compartments in type 2 diabetic subjects. It is not known which PPAR gamma agonist-induced changes in adipose tissue metabolism are responsible for the fat redistribution and improvement in insulin

sensitivity. The Specific Aims of this application are as follows: (1) To determine changes in adipose tissue metabolism and respiratory quotient that accompany PPAR gamma agonist-mediated increased insulin sensitivity in nondiabetic obese insulinresistant human subjects. (2) To examine regional variation in PPAR gamma agonistmediated effects in vitro on metabolism and gene expression, in different subcutaneous abdominal and visceral fat depots from morbidly obese human subjects. (3) To examine whether PPAR gamma agonists mediate changes in adipose tissue that may alter susceptibility to weight gain in rodents when exposed to a high fat diet, post-treatment. The results of these studies will assist physicians in predicting which patients will best respond to thiazolidinedione therapy, and will help to develop strategies to minimize weight gain during and after treatment with PPAR gamma agonists.

Project Title: PRENATAL EXPOSURES AND PREECLAMPSIA PREVENTION Principal Investigator & Institution: Roberts, James M.; Director, Magee-Womens Research Institut; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 01-DEC-2001; Project End 30-NOV-2002 Summary: In this proposal we test the role of oxidative stress in the pathophysiology of preeclampsia. Oxidative stress generates free radicals that injure tissues, especially vascular endothelial cell function as components of oxidized LDL (ox-LDL), alter endothelial cell structure and function. Data from our lab and others support alterations of endothelial cell function as a component of the pathophysiology of preeclampsia. In addition, preliminary data from our group indicates potential generation of pro oxidants by preeclamptic placenta. We demonstrated increased xanthine oxidase/dehydrogenase, an enzyme which can generate superoxide, in invasive cytotrophoblast from preeclamptic women. We recently demonstrated material in the blood or plasma of preeclamptic women that increases ascorbate oxidation in vitro. We propose to characterize the activity. Whether these findings indicate cause or effect or are an epiphenomenon cannot be answered by available data. We propose definitively testing a causal role. We will study circulating markers of oxidative stress before, during and after preeclampsia. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: PROTEASE INHIBITOR RELATED ADIPOGENESIS IN HIV INFECTION Principal Investigator & Institution: Agrawal, Krishna C.; Regents Professor and Chairperson; Pharmacology; Tulane University of Louisiana New Orleans, La New Orleans, La 70112 Timing: Fiscal Year 2002; Project Start 01-AUG-2001; Project End 31-MAY-2004 Summary: (Provided by applicant) The clinical use of HIV-1 protease inhibitors (PIs) in highly active anti-retroviral therapy (HART) has led to significant improvements in the prognosis and quality of life in HIV-1 infected patients. However, long-term use of PIs has resulted in side effects such as peripheral lipodystrophy, hyperlipidemia, insulin resistance, and disruption of the adipogenic process. Our preliminary studies have shown that PIs suppress adipogenic differentiation in 3T3-L1 cells and the addition of TNFalpha further suppressed the rate of adipogenesis. In contrast, the insulin sensitizing agent, troglitazone, blocked this suppression even in TNFalpha sensitized cells. The primary goal of the proposed research is to investigate the molecular

51
mechanisms involved in the PI-induced modulation of adipogenesis and to test the hypothesis that preadipocytes are sensitized by HIV-1 induced inflammatory cytokine TNFalpha and/or HIV-1 Tat protein, to PI-induced disruption of adipogenesis. This will be achieved by the following specific aims: 1.) To determine the in vitro effects of PIs on adipogenic differentiation in human bone marrow stromal progenitor cells. Transcripts of early, middle and late genetic markers i.e., pref-1, lipoprotein lipase (LPL) and GAPDH, respectively will be determined. Levels of nuclear transcription factors, PPARgamma and C/EBP-alpha will be determined by transient transfection assays and gel mobility shift assays. 2.) to determine the sensitizing effect of the HIV-1 induced inflammatory cytokine, TNFalpha and/or HIV-1 Tat protein on PI-induced inhibition of adipogenic differentiation in human bone marrow stromal progenitor cells. 3.) To determine the in vitro effects of PIs on the activity of ECM degrading proteases in human stromal adipogenic progenitor cells. Fibrinolytic activity in undifferentiated and differentiated cells will be monitored by using a chromogenic plasmin substrate. The ECM production at different stages of differentiation will be determined by SDS-PAGE electrophoresis and the activation of ECM degrading proteolytic enzymes (MMPs) will be monitored by gelatin zymography. Real time RT-PCR studies will monitor gene expression of tPA, PAI-1/2 and MMPs/TIMPs which are involved in the fibrinolytic cascade. 4.) To investigate the ameliorative effects of insulin sensitizers on PI-induced lipodystrophy. We will investigate the efficacy of thiazolidinediones (rosiglitazone and pioglitazone) and biguanides (metformin) in suppressing the effects of PI-induced inhibition of adipogenic differentiation. These studies will delineate the molecular mechanisms that may be responsible for the adipogenic side effects induced by the PIs in the presence of HIV infection.

Project Title: REGULATION OF CYTIDYLYTRANSFERASE IN FETAL RAT LUNG Principal Investigator & Institution: Mallampalli, Rama K.; Professor; Internal Medicine; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2002; Project Start 01-APR-1996; Project End 31-DEC-2005 Summary: (provided by applicant): Surfactant deficiency plays an integral role in the pathogenesis of neonatal lung diseases such as RDS and acute lung injury. Although surfactant replacement therapy has made an impact in RDS, it is not totally effective. An alternative strategy to increase the alveolar surfactant pool is by stimulating biosynthesis. Surfactant synthesis is tightly controlled by the rate-limiting enzyme, cytidylyltransferase (CT). CT activity is inhibited by sphingolipids and stimulated by fatty acids. However, prior studies administering fatty acids in vivo to stimulate surfactant production have had mixed success with associated toxicity. Thus, the goal of this proposal is to develop a novel and safe approach to stimulating surfactant synthesis in fetal lung by the use of very low density lipoproteins (VLDL) and lipoprotein lipase (LPL). This revised competing renewal expands from recent advances in our laboratory made through support of the existing grant showing that 1) fatty acids carried within very low density lipoproteins (VLDL) are potent stimulators of CT activity in vitro in the presence of LPL and 2) oxidized lipoproteins inhibit surfactant synthesis,. These observations led to the hypothesis that native lipoprotein loading and oxidized lipoproteins differentially regulate the CT enzyme. We will investigate whether loading with native lipoproteins (VLDL) increases CT activity by altering fatty acids and sphingolipids associated with the enzyme (AIM 1). We will also investigate how modified (oxidized) lipoproteins acutely down-regulate surfactant synthesis by inducing CT proteolysis (AIM 2). Our hypothesis will be tested, in vivo, by maternal

Lipase
administration of lipoproteins in pregnant rats and with analysis conducted in primary fetal type II cells. These in vivo studies will be supplemented with use of a lipoproteinresponsive type II (MLE12) cell line. The unique contributions of this proposal impacting the field of surfactant metabolism include: 1) mechanistic studies with potential clinical application by which native lipoproteins control CT function posttranslationally (AIM 1) and 2) studies investigating CT regulation at the level of protein stability (AIM 2).

Project Title: REGULATION OF EPITHELIAL CELL MOTILITY BY VILLIN Principal Investigator & Institution: Khurana, Seema; Associate Professor; Physiology; University of Tennessee Health Sci Ctr Memphis, Tn 38163 Timing: Fiscal Year 2004; Project Start 01-APR-2004; Project End 31-MAR-2009 Summary: (provided by applicant): The PI proposes to determine and characterize the role of villin and its ligands (phosphatidylinositol 4,5- bisphosphate (PIP2) and actin) in epithelial cell motility. Active cell motility regulates many important intestinal epithelial cell functions, including: ion transport proteins via endocytosis and exocytosis, crucial for absorption of nutrients; intestinal restitution, important to maintain homeostasis in the presence of large osmotic and mechanical stress; the movement of cells along the crypt-villus axis; the invasion and propagation of enteropathogens; immune surveillance and inflammation; as well as neoplastic tumor cell dissemination and metastasis. Villin is an actin nucleating, capping, severing, and bundling protein. Villin binds and regulates two ligands that are known to regulate cell motility, phospholipase C-gamma1 (PLC-gamma1) as well as the substrate of the lipase namely, phosphatidylinositol 4,5-bisphosphate (PIP2). Recent studies with villin knock out mice have demonstrated that villin is necessary to regulate epithelial cell motility. In addition, villin shares sequence homology with other proteins of its family including gelsolin, which have been shown to regulate cell motility in vivo. Our working hypothesis is that villin's ability to regulate phosphoinositide-mediated signal transduction pathways and the actin cytoskeleton is important to epithelial cell physiology and pathophysiology involving changes in cell motility. To accomplish our overall study objectives we will characterize the villin-PIP2 interaction using the following approaches: reconstitution in vitro using recombinant villin proteins; endogenous villin expression in the intestinal epithelial cell line, Caco-2; and over expression of villin and enzymes that regulate intracellular PIP2 levels, in the villin null intestinal cell line, IEC-6 using a tetracyclineregulated system. To determine unequivocally the role of villin in the epithelial cell motility, we will use villin knock out mice. These studies promise the prospect of modifying motility for enhancement of normal physiology and for amelioration of disease. Inhibition of epithelial cell motility can be significant in several diseases, including inflammatory bowel disease, celiac disease, and colon cancer.

53
LPL regulation is complex. We have described regulation of LPL translation in response to catecholamines, thyroid hormone, and in diabetes. Our recent studies have described an RNA binding protein that inhibited translation through binding to the 3'UTR of the LPL mRNA. We have now identified a member of the RNA binding complex as the alpha catalytic subunit of cAMP dependent protein kinase (PKA). In addition, we have produced transgenic mice that express an LPL gene (LPLt) that lacks the RNA binding motif on the 3'UTR. Our future aims are to better characterize the role of PKA in LPL regulation, and to better understand the role of translation in the physiologic regulation of LPL. Hypothesis 1. Protein kinase A (PKA) is involved in the translational regulation of LPL. Aim 1. Characterize the binding of the PKA C subunit to LPL mRNA: tissue specificity and involvement of other proteins. Aim 2. Determine the sequence and kinase activity of the C subunit involved in translational regulation. Aim 3. Characterize the motif on the 3'UTR of LPL that is involved in C binding. Aim 4. Determine whether LPL translation is altered in PKA knockout mice. Hypothesis 2. Regulation of LPL translation is important physiologically. Aim 1. Examine the translational regulation of both LPLt and wild type LPL (LPLwt) in response to epinephrine, thyroid hormone, and phorbol ester in isolated adipocytes from transgenic mice. Aim 2. Examine the regulation of LPLt and LPLwt in adipose tissue of transgenic mice following the induction of streptozotocin-diabetes or hypothyroidism, and the in vivo administration of epinephrine. Aim 3. Examine the mechanism by which the expression of LPLt in transgenic mice is accompanied by a down regulation of wild type LPL.

Project Title: RESOLUTIONS IN BRANCHED ALKANES USING LIPASE IN BEADS Principal Investigator & Institution: Neau, Steven H.; Pharmaceutical Sciences; University of Missouri Kansas City Kansas City, Mo 64110 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2005 Summary: (provided by applicant): The long-term goals of this research are to investigate and characterize fresh and freeze-dried macromolecule-loaded polysaccharide-based hydrogel beads for applications in chemical reactions, and their application in macromolecule delivery for therapeutic purposes. The use of these beads for therapeutic peptide and protein delivery will be pursued, in particular for site specific delivery of these agents to the colon following oral administration. Various chemical reactions can be investigated using entrapped enzymes. The long-term goals include applications of these beads in reactions where the catalysis is well characterized, such that the bead performance (and not the reaction) is studied. The proposed research incorporates lipase into these beads for easy recovery and subsequent delivery. The solvents are straight chain and methyl-branched alkanes to test the hypothesis that branching can enhance the activity and enantioselectivity of lipase. The short-term goal is the resolution of the pharmacologically active enantiomer of a drug that is a racemic mixture, ibuprofen, by enantioselective esterification by a lipase that is free or entrapped in the chitosan bead. Isolation of the active, enantiomer will become a regulatory requirement because administration of only the active enantiomer can reduce the toxicity and dose. Resolution using an entrapped lipase offers a rapid, enantioselective reaction; repeated applications since the enzyme can be recovered; and economical terminal resolution in the synthesis sequence. In the first study, the solvent system, consisting of water at a known activity in an alkane, will be optimized for the fastest reactions and the highest enantioselectivity. Michaelis-Menten parameters will be evaluated and compared. In the second study, lipase-loaded chitosan hydrogel beads

are fabricated. The successful rugged, spherical matrix can entrap the enzyme, minimally interfere with activity, and allow substrate and product diffusion. Permeability of the bead will be investigated by measuring the substrate diffusion coefficient within the bead. Reaction parameters of the entrapped enzyme will be compared to those of the free enzyme in the third study. The stability of the bead, the efficiency of the lipase entrapment, and the reduction in lipase activity as a function of repeated applications will also be evaluated in the third study.

Project Title: RETINOID METABOLISM IN HEPATITIC STELLATE CELLS Principal Investigator & Institution: Bosron, William F.; Professor; Biochem and Molecular Biology; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-JUL-2006 Summary: (provided by applicant): The overall goal of this proposal is to understand the role of specific rat retinoid metabolizing enzymes (especially retinyl ester hydrolases) in the regulation of retinoid metabolism in hepatic stellate cells. Hepatic stellate cells are the main reservoir of Vitamin A in the liver where it is stored mainly as retinyl palmitate in highly visible intracellular lipid droplets. When animals are exposed to hepatotoxins or humans chronically abuse alcohol, the stellate cells become activated and transform into myofibroblast-like cells. These transformed cells are the sites of collagen and extracellular matrix protein formation in alcohol-induced hepatic fibrosis. One of the earliest events in stellate cell activation is the hydrolysis of retinyl esters and the depletion of the intracellular lipid droplets. The most likely retinyl ester hydrolase candidates are the members of the families of broad substrate specificity lipases and carboxylesterases. The specific retinyl ester hydrolases expressed in hepatic stellate cells and the mechanisms for regulation of their activity during stellate cell activation is not known. In preliminary data, we show that the five most common rat liver carboxylesterases with retinyl palmitate activity are not highly expressed in stellate cells. However, the hormone-sensitive lipase gene is expressed in rat hepatic stellate cells and it has retinyl palmitate hydrolase activity in vitro. The goals of the grant are to identify the specific retinyl ester hydrolases (lipases and carboxylesterases) that are expressed in isolated rat liver cells (stellate cells, Kupffer cells, hepatocytes) by real-time, quantitative PCR of RNA and immunofluorescence microscopy of stellate cells with enzyme-specific antibodies. The expression of retinyl ester hydrolases and retinol dehydrogenases will be correlated with retinoid autofluorescence in lipid droplets and expression of cellspecific markers in cultured rat stellate cells as they undergo activation to myofibroblast-like cells. When feasible, we will measure retinyl palmitate hydrolase activity and perform protein gel electrophoresis of cellular extracts with esterase activity staining. We will examine the kinetics of purified rat stellate cell retinyl ester hydrolases and examine the effects of enzyme activators and inhibitors. Inhibitors of retinyl ester hydrolysis in stellate cells may be an effective therapeutic strategy for arresting stellate cell activation early in hepatic fibrosis.

Although several reports suggest that aberrant cholesterol metabolism may play a role in AMD pathogenesis, the underlying cell biology of this process is unclear. Published work from our laboratory demonstrates that the lipofuscin component A2E delays the degradation of rod outer segment lipids in retinal pigment epithelial (RPE) cells without affecting protein processing. The first specific aim of this proposal will extend this work by investigating the mechanistic aspects of A2E-induced phospholipid and cholesterol accumulation in the RPE. Lysosomal lipase activities, transcriptional activation and enzyme-substrate interactions will be studied in the presence and absence of A2E. The second specific aim will examine the roles of the LDL receptor, the scavenger receptor class B type l, caveolin-1 and the ATP-binding cassette transporter A1 in polarized lipoprotein internalization and cholesterol/phospholipid efflux pathways in the RPE and investigate how A2E affects these processes.

Project Title: ROLE OF SPHINGOMYELIN IN LIPOPROTEIN METABOLISM Principal Investigator & Institution: Subbaiah, Papasani V.; Professor; Rush University Medical Center Chicago, Il 60612 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2007 Summary: (provided by applicant): The long term objective of this proposal is to investigate the physiological role of sphingomyeIin (SPH) in plasma, where it is the most abundant phospholipid next to phosphatidylcholine (PC). In contrast to its functions in membrane cholesterol metabolism and signal transduction, the role of SPH in the metabolism of plasma lipoproteins has received little attention, although its concentration is significantly increased in atherosclerosis and aging. Based on preliminary data, the PI proposes that SPH modulates plasma lipolytic activities, reverse cholesterol transport pathways, and lipid peroxidation reactions, thereby preventing excessive turnover and premature degradation of PC and cholesterol.The PI will test the hypothesis that SPH, by virtue of its structural similarities to PC, competitively inhibits not only LCAT, as he previously showed, but also other lipolytic enzymes that hydrolyze PC, such as hepatic lipase and secretory phospholipases A2. He will also investigate the mechanism(s) involved in the inhibition of these activities, by employing monolayer techniques, enzyme kinetics, and structural modifications of the SPH molecule. The role of SPH in the exchange of free cholesterol and cholesteryl ester (CE) between lipoproteins, and in the selective uptake of HDL CE by various cells in culture will be studied by manipulating the SPH concentration of native lipoproteins and recombinant HDL (rHDL) particles. Since the surface concentration of CE determines its transfer rate, the effect of SPH on the partitioning of CE into surface lipids of rHDL will be investigated by [13C] NMR. The possible role of membrane SPH in the function of SR-B1 receptor will also be investigated.The PI proposes to test the novel hypothesis that SPH inhibits lipid peroxidation by retarding the propagation of lipid peroxy radicals and that the increased oxidative susceptibility of small dense LDL, compared to buoyant LDL, is due to the low SPH/PC ratio in the former. He will correlate the oxidizability of various LDL subfractions and synthetic liposomes with their SPH/PC ratios. The mechanism by which SPH inhibits lipid peroxidation will be investigated by using structural analogs of SPH, by oxidizing fluorescent probes which are specifically localized in the surface or core of lipoproteins, and by studying the effects of SPH on membrane fluidity and lateral diffusion rates.The results from these studies should

Project Title: SECRETION AND BIOSYNTHESIS OF INSULIN Principal Investigator & Institution: Mcdaniel, Michael L.; Professor; Pathology and Immunology; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2002; Project Start 01-MAY-1977; Project End 31-JAN-2007 Summary: (provided by applicant) Type 2 diabetes is associated with obesity and elevated plasma levels of free fatty acids (FFA) and triacylglycerides (TAG). Obesity is also associated with the development of insulin resistance in insulin-sensitive tissues that results in hyperglycemia and hyperinsulinemia. b-cell failure in obesity-associated type 2 diabetes is believed to correlate with the intracellular accumulation of lipids that contribute to defects in insulin secretion and/or insulin and growth factor signaling necessary to maintain sufficient b-ceIl mass. The overall goal of this proposal is to define the cellular mechanisms whereby FFA and TAG exert their inhibitory effects on b-cell function in obesity-associated type 2 diabetes. Our recent studies have identified lipoprotein lipase (LpL) in b-cells, a key enzyme for catalyzing the hydrolysis of lipoprotein-associated TAG, to produce FFA for local cellular uptake. Our overall hypothesis is that LpL serves as a gatekeeper for the physiological import of FFA into bcells analogous to that described for adipocytes. Furthermore, our new findings indicate that elevated concentrations of glucose and insulin enhance LpL enzyme activity in bcells that may explain how b-cells continue to accumulate lipids in the setting of hyperglycemia and hyperinsulinemia associated with type 2 diabetes. In specific aim 1, we will: 1) further characterize the ability of nutrients, glucose and amino acids, and insulin to regulate LpL activity, expression and intracellular localization in rodent and human islets and b-cell lines, 2) assess the role of rapamycin, an inhibitor of mTOR, to regulate LpL and: lipid levels, and 3) evaluate LpL function in vivo. In specific aim 2, we will 1) examine the effects of enhanced FFA uptake by overexpression of FATP1 and ACS1, 2) characterize lipid droplet associated proteins, ADRP, perilipins and HSL, and 3) determine the regulation of lipid droplet synthesis and breakdown by phosphorylation and overexpression of lipid droplet associated proteins. Mitochondria exert a major role in glucose-stimulated insulin secretion, and mitochondrial activation is required for normal signal transduction. Recent studies suggest that FFA up-regulate mitochondrial uncoupling proteins (UCP) proposed to dissipate the proton gradient across the mitochondrial inner membrane. In specific aim 3, we will: 1) determine the role of UCP in mediating b-cell function by overexpressing UCP-2 in islets and b-cell lines, 2) assess the modulation of UCP-2 by increased levels of FFA in vitro and in vivo as described in specific aims 1 and 2. This experimental approach will be used to delineate the link between FFA and b-cell mitochondrial dysfunction. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: SELECTIVE UPTAKE FROM LDL:ROLE OF THE PLASMA MEMBRANE Principal Investigator & Institution: Seo, Toru; Medicine; Columbia University Health Sciences Po Box 49 New York, Ny 10032 Timing: Fiscal Year 2002; Project Start 15-FEB-2002; Project End 31-DEC-2004 Summary: (provided by applicant) The applicant's long-term goal is to determine the cholesterol delivery mechanisms and their regulation. Cholesterol delivery to cells and

tissues is a critical process in maintaining normal cell function. Specifically, regulatory roles of free cholesterol (FC) and free fatty acids (FFA) on cholesterol delivery have been of interest since they affect cell lipid metabolism at various levels; influx and efflux of lipoproteins as well as direct effects on cell receptors and lipogenic processes at genetic levels. The proposed studies will examine selective uptake (SU) as a mechanism for cell cholesterol delivery and its regulation by FC and FFA, and will allow the applicant to expand his research competition. New techniques such as fluorescent microscopy and use and generation of transgenic mice used in studies herein will provide new skills for future studies. Our previous studies demonstrated that J774 macrophages incubated with FFA increased not only LDL uptake by the LDL receptor (LDLR), but also markedly stimulated SU of cholesteryl esters (CE) from LDL. Although LDL uptake via LDLR is a primary cholesterol delivery pathway, other pathways such as SU are important in cells and tissues with little or no LDLR. Since an initial step of SU likely involves the CE transfer to the plasma membrane, the role of the plasma membrane, particularly FC and sphingolipid rich membrane rafts, as a CE acceptor will be determined by assessing transfer of (3H) cholesteryl ethers from LDL core to isolated membranes or large unilamellar vesicle (LUV) as model membranes. Moreover, since FC modulates membrane fluidity, changes in FC content in membranes on CE transfer from LDL will be examined (Aim 1). Similarly, potential roles of FFA on regulating SU will be examined by directly intercalating various FFA, or altering phospholipid content in the plasma membrane that occurs in cells incubated with FFA (Aim 2). The second step of SU, internalization of membrane CE, will be addressed by using fluorescently labeled LDL, where LDL-CE and apolipoprotein B (apoB) will be traced with fluorescent BODIPY and ALEXA, respectively. Studies will be performed to determine what cell organelles are required for CE internalization by disrupting various cell organelles with specific inhibitors. We will determine whether membrane rafts are required for CE internalization and whether FFA affect raft-mediated CE trafficking by in situ colocalization of CE and membrane rafts in the presence or absence of FFA. Also, two different SU pathways, mediated by lipoprotein lipase vs. FFA, will be compared to determine whether CE internalization by these pathways are different (Aim 3). Finally, the physiological relevance of LDL SU in tissues will be determined using mutant mice and whether dietary intakes of different fats modulate cholesterol delivery to tissues via SU from LDL and whether macrophage specific expression of LpL stimulates cholesterol delivery to extrahepatic tissues (Aim 4). Roles of SU and its regulation by FC and FFA will be delineated and results from these studies will provide further understanding on mechanisms of cholesterol delivery to cells.

Project Title: STRUCTURE-FUNCTION ANALYSIS OF COLIPASE AND LIPASE Principal Investigator & Institution: Lowe, Mark E.; Professor of Pediatrics and Director; Pediatrics; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2002; Project Start 01-AUG-1996; Project End 31-MAR-2006 Summary: The long-term goal of this project is to describe the biochemical mechanisms of the lipolytic enzymes responsible for dietary fat digestion. Dietary fats provide a major source of energy, essential fatty acids, a vehicle for fat-soluble vitamins, and components of cellular membranes. Fats eaten in excess adversely affect health increasing the risk of cardiovascular disease and obesity. Before fats can be absorbed, they must be digested. Lipases in the stomach and duodenum digest dietary fats. This proposal focuses on the lipase responsible for the majority of fat digestion, pancreatic triglyceride lipase, and another pancreatic protein, colipase, which is required, by
58
Lipase
pancreatic triglyceride lipase for activity. We propose that specific interactions among lipase, colipase, lipids, and bile salts, which are necessary for absorption of the fatty acids released by lipase, dictate the function of pancreatic triglyceride lipase. The first specific aim is to characterize the mechanisms that mediate specific interactions among lipase, colipase, bile salts, and lipids. We will substitute selected amino acids in lipase or colipase by site-specific mutagenesis to identify functionally important regions of both proteins. The second specific aim is to determine the mechanisms that trigger the conversion of lipase from an inactive to an active conformation. In aqueous solution lipase is inactive. When lipase encounters the lipid substrate its conformation changes and it becomes active. We will follow the conformational change by tryptophan fluorescence to determine the factors that influence this critical conformational change. The last specific aim is to develop an expression system for labeling recombinant colipase with stable isotopes. The ability to label colipase with stable isotopes will enable NMR studies of the conformation of colipase in aqueous solutions under different conditions. We will test various culture conditions to improve our current system for the production of 15N labeled colipase and we will develop a system for economically labeling colipase with 13C and 15N. These studies will determine the biochemical details of the interactions between lipase, colipase, lipids, and bile salts that impact lipase function. The results will ultimately permit us to manipulate these interactions for therapeutic purposes. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: STUDIES OF REGIONAL FAT DISTRIBUTION AND ENERGY BALANCE Principal Investigator & Institution: Weigle, David S.; Associate Professor of Medicine; Medicine; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 01-MAR-2001; Project End 31-JAN-2006 Summary: The studies in this application are designed to better understand the regulation of body fat mass and the mechanisms determining body fat distribution in humans. Three Specific Aims are proposed: 1. To determine whether experimentallyinduced or spontaneous variations in plasma leptin levels predict subsequent changes in body composition. The protocols employed will also elucidate the mechanism by which high carbohydrate diets induce satiety and weight loss, and the mechanism of involuntary weight loss in the elderly. 2. To examine the relationships among central body fat redistribution, changes in adipogenic gene expression, and atherogenic changes in plasma lipids and insulin sensitivity. The model for this work will be the body fat redistribution that occurs in subjects receiving aggressive antiretroviral therapy for HIV infection. 3. To determine whether changes in uncoupling protein (UCP) gene expression act to attenuate diet-induced changes in body fat mass. This study will use the technology developed for Specific Aim 2 to ascertain whether muscle and fat UCP expression change in parallel with energy expenditure following experimental weight gain and weight loss in human subjects. The applicant has successfully trained several young physician investigators in patient-oriented and basic research, and a plan to continue doing so is presented.

Project Title: STUDY OF THE DYNAMIC BINDING, STRUCTURE-FUNCTION OF CIII Principal Investigator & Institution: Breyer, Emelita D.; Chemistry; Georgia State University University Plaza Atlanta, Ga 30303
Studies
59
Timing: Fiscal Year 2003; Project Start 15-JUL-2003; Project End 30-JUN-2008 Summary: (provided by applicant): Recent study shows that Apolipoprotein CIII (CIII) specifically binds and inhibits Lipoprotein Lipase (LpL) and Hepatic Lipase (HL) enzymes. The significance of the N-terminal domain in stabilizing the lipid-protein interaction and displacing Apolipoprotein E (E) was also identified (1). Our previous study that confirms the ability of CIII to displace E (2), sets up the stage for further structure-function studies evaluating the factors that enable CIII to displace E, and inhibits both HL and LpL. These functions should be investigated in correlation to CIIl's ability to bind to the lipoprotein particle (Lp) with varying size and composition. The cooperative and complex conformational modification of CIII binding to Lp and LpL/HL suggests that this study requires a factorial design experiment that can extract latent variable (factors) from collinear measurements of the protein's physico-chemical properties and structure (X-matrix), and relate these factors to the extracted latent variables from the Y-matrix consisting of the protein's functions. This study will be the first attempt to evaluate the structural factors in CIII that is responsible for the above functions in a systematic way using a factorial designed experiments. By using our model structure of CIII generated by homology with E crystal structure followed by molecular mechanics modeling, we are able to identify significant residues in CIII that may give us information regarding the difference in its function with respect to E and CII. Structural factors such as helix length, positive helix cap, loop flexibility, and hydrophobicity of side chains will be evaluated using different constructs in order to assess their contribution to the different functions of CIII. This approach is designed to give us a surface plot describing how the structural factors of CIII correlate with its functions. A more structured search and prediction of Clll analog that has a high lipid binding ability but with lipase inhibitory sites replaced by either the activating site of CII or E can be made using this approach.

Project Title: THE ROLE OF HEPATIC LIPASE IN CHOLESTEROL HOMEOSTATIS Principal Investigator & Institution: Dichek, Helen L.; Pediatrics; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 01-JUL-2001; Project End 31-MAY-2006 Summary: The enzyme hepatic lipase (HL) is central to cholesterol homeostasis. HL participates in the regulation of plasma cholesterol levels, a major risk factor for atherosclerosis. It also mediates steroid hormone production, by controlling access to exogenous cholesterol in steroid-producing tissues. In turn, increased production of the adrenal steroid cortisol (corticosterone in mice) as occurs in stress, depression and certain tumors of adrenal and pituitary origin, modulates the development of atherosclerosis: increased cortisol levels are linked to an increased risk for atherosclerosis. However, HL's precise role in atherosclerosis is unknown. HL exerts its role via at least two functions. Its catalytic function processes lipoproteins for both receptor-mediated endocytosis and selective cholesterol uptake. Its bridging function facilitates interactions between lipoproteins, receptors, and the plasma membrane, thereby modulating lipoprotein cholesterol flux. This proposal seeks to establish the respective contributions of the catalytic and bridging functions to the cellular uptake of lipoprotein cholesterol and atherosclerosis by generating transgenic mice that express wildtype HL and functional mutants of HL. These mice will be bred with mice deficient in endogenous HL(hl-/-) and with h1-/- mice that are also deficient in the low density lipoprotein (LDL) receptor to generate Ldlr-/-hl-/- mice. (The Ldlr-/- mice serves as a model for diet-induced atherosclerosis). Thus, we will determine the effect of the
60
Lipase
expression of wildtype and mutant HLs on plasma lipid and lipoprotein concentrations, composition and size, and lipoprotein turnover. The mechanisms of lipoprotein cholesterol uptake will be examined in primary hepatocyte cultures from the livers of these mice by determining the effects of wildtype and mutant HL on cellular binding and uptake of labeled lipoproteins in the presence of specific inhibitors of cellular receptors. The effect of expression of wildtype and mutant HL on atherosclerosis development will be established in high-fat diet fed wildtype and mutant HL expressing mice on the Ldlr-/-hl-/-background. In addition this proposal seeks to establish the role of HL in regulating the adrenal steroidogenic response to stress and to identify the contribution of the catalytic function of HL to the adrenal steroidogenic response to stress. This will be accomplished by determining plasma corticosterone response, adrenal cholesterol content and adrenal expression of receptors and enzymes involved in cholesterol metabolism, in response to chronic pharmacologic stimulation of corticosterone production in wildtype- and mutant HL-expressing mice and compared to nontransgenic mice.

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with lipase, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “lipase” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for lipase (hyperlinks lead to article summaries):

PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND LIPASE Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and lipase.
Finding Nutrition Studies on Lipase The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “lipase” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. PATENTS ON LIPASE Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “lipase” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on lipase, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Lipase By performing a patent search focusing on lipase, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We

protease agent in a suitable vehicle and an effective amount of a sacrificial lipase substrate and/or a sacrificial protease substrate in a suitable vehicle. Excerpt(s): The present invention relates to a composition for the prophylaxis and/or treatment of diaper dermatitis or similar dermal irritation and methods for making and using the composition. More particularly, the present invention relates to a composition including an enzyme inhibitor system, a sacrificial substrate system or a combined system for the prophylaxis and/or treatment of tissue irritation due to enzyme activity, especially protease and lipase enzyme activity, and methods for making and using such compositions. The compositions of the present invention are especially useful in inhibiting the activity of lipase and protease enzymes present in expressed feces that cause diaper dermatitis or similar dermal conditions or in tissues exposed to bodily fluids or any fluid containing lipase and protease enzymes or the exposure of tissues to any composition (solid, liquid, emulsion, dispersion, etc.) containing lipase and protease enzymes. Diaper dermatitis is a phenomenon frequently encountered by parents of small children or by patients in nursing homes who are required to wear a diaper. Although the dermatitis is treatable, occurrence and persistence often results in unhappy children and sleep deprived parents. In severe cases, it results in painful decubitus ulcers. Many ointments and powders exist on the market for treating and preventing diaper dermatitis, but most function by merely forming a barrier between the skin and expressed feces.

Enzymatic methods for polyunsaturated fatty acid enrichment Inventor(s): Breton; Gildas (Penanguer, Concarneau, FR F-29900) Assignee(s): none reported Patent Number: 6,537,787 Date filed: March 13, 1998 Abstract: A process for obtaining polyunsaturated fatty acid concentrates comprising subjecting a fish oil containing docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), to a selective enzymatic hydrolysis in position 1, 3 or 2, to obtain a mixture of free fatty acids, monoglycerides and diglycerides, separating the constituents of this mixture, collecting the free fatty acids which are purified by crystallization from urea, to increase the EPA and DHA content, decomplexing the isolated fatty acids by an interesterification between the free fatty acids concentrated into polyunsaturated fatty acids and the crude oil, in the presence of a lipase specific for position or steric hindrance, to obtain a mixture enriched with polyunsaturated fatty acid triglycerides which is separated and freed from the free fatty acids and a process for enrichment with polyunsaturated fatty acids (EPA, DHA) of phospholipids by an enzymatic route, as well as in the synthesis of monoacylglycerols of polyunsaturated fatty acids of the n3 series, by enzymatic synthesis starting with a 1,2-dialkylene glycerol which are useful in the domain of foodstuffs, cosmetics and pharmacology. Excerpt(s): A subject of the present invention is new processes for the production of polyunsaturated fatty acid esters in a pure or concentrated form. A more particular subject of the invention is processes for the production of esters of polyunsaturated fatty acids of the.omega.-3 series starting with glycerides of fatty acids extracted from fish oils, phospholipids, or 1,2-dialkyene glycerols, using an enzymatic treatment.

Esterification or hydrolysis with substrate treated un-dried immobilized lipolytic enzyme Inventor(s): Kase; Minoru (Ibaraki, JP), Komatsu; Toshiteru (Ibaraki, JP), Shimizu; Masami (Ibaraki, JP), Shimizu; Masao (Ibaraki, JP) Assignee(s): Kao Corporation (Tokyo, JP) Patent Number: 6,716,610 Date filed: December 2, 1999 Abstract: A lipolytic enzyme such as lipase is adsorbed on a porous anion-exchange resin carrier to obtain an immobilized enzyme without drying. The un-dried immobilized enzyme is contacted with a fat or oil for a time which may be about 2 hours to about 24 hours to stabilize the immobilized enzyme, and the immobilized enzyme is recovered from the fat or oil. The recovered immobilized enzyme is then used for esterifying or hydrolyzing a substrate. Water content of the un-dried immobilized enzyme may be 20% or more be weight such as 20-60%. Prior to immobilization, the resin carrier may be treated with a lypophylic aliphatic acid which preferably has 8 to 18 carbons. Excerpt(s): The present invention relates to a process for preparing an immobilized enzyme showing a high activity with a less loss in the enzyme activity, which is used for hydrolysis of fats and oils, ester-exchange of fats and oils, and esterification of aliphatic acids and alcohols. The term of "fats and oils" means an inclusion of a fat, an oil, a lard, a grease and so on. In hydrolyzing fats and oils by a lipolytic (or fat and/or oildecomposing) enzyme, an immobilized enzyme prepared by immobilizing a lipolytic enzyme onto an inorganic or organic carrier is used for efficient use of the enzyme. To raise the absorptivity of the enzyme onto a carrier and to improve an enzyme activity, various studies have been made, and for example, JP-A 9-257 discloses a process for producing an immobilized enzyme carrier prepared by immobilizing a lipase onto an inorganic carrier treated with a silane coupling agent having a special functional group, washing and drying it, and impregnating it with an aliphatic acid. Even by this method, however, the amount of the adsorbed enzyme and the enzyme activity remain still insufficient. Further, an immobilized enzyme prepared by immobilizing a lipolytic enzyme called lipase onto a carrier is used as an enzyme mainly for use in reactions for the object of ester-exchanging (ester-interchanging or transesterifying) fats and oils and esterifying aliphatic acids and alcohols. These reactions are advantageously conducted at concentrations of water as low as possible (1000 ppm or less) to inhibit hydrolysis, and thus the immobilized enzyme is forcibly dried to give only several % water content in the carrier, since the immobilized enzyme is prepared.

Expression methods Inventor(s): Dalrymple; Michael (Dalgety Bay, GB), Lundberg; Lennart (Billdal, SE), Stromqvist; Mats (Ume.ang., SE) Assignee(s): AstraZeneca AB (Sodertalje, SE) Patent Number: 6,525,241 Date filed: July 18, 1999 Abstract: The present invention relates to human bile salt-stimulated lipase (BSSL) obtainable from transgenic sheep. The invention further relates to transgenic sheep whose germ cells and somatic cells contain a recombinant nucleotide molecule comprising a nucleotide sequence encoding for human BSSL. The invention also relates to methods for producing said transgenic animals, as well as to methods for producing human BSSL derived from transgenic animals. In addition, the invention provides the use of compositions comprising BSSL in the treatment of diseases relating to exocrine pancreatic insufficiency, and for improvement of the utilization of dietary lipids in preterm born infants. Excerpt(s): Bile Salt-Stimulated Lipase (BSSL) is the major lipolytic activity present in human milk (Wang & Johnson, 1983; Wang & Hartsuck, 1993). As its name implies, the enzyme is not active in the milk but is activated in the intestine by bile salts. In mammals a similar enzyme activity is also secreted from the pancreas into the intestine. The cDNA sequences for both the mammary and pancreatic enzyme are identical indicating that they are the product of a single gene (Reue et al., 1991; Lidberg et al., 1992). BSSL shares with other pancreatic lipases a triacylglycerol hydrolase activity but BSSL is the only intestinal lipase which hydrolyses cholesterol ester and other fatty acid esters, such as vitamin A ester. The protein is stable to both proteases and the acid environment in infant stomachs. These unique activities and the large quantity of BSSL in human milk suggest that this enzyme is physiologically important. The cDNA sequence (SEQ ID NO: 2) and deduced amino acid sequence (SEQ ID NOS: 3and 4) of BSSL have been disclosed by Nilsson et al. (1990); in U.S. Pat. No. 5,200,183 (Oklahoma Medical Research Foundation); and in WO 91/18923 (Astra AB). Human BSSL is a glycoprotein consisting of 772 amino acids. The C-terminal portion is composed of 16 repeats each of 11 amino acids having consensus PVPPTGDSGAP (SEQ ID NO: 5). The genomic DNA sequence (SEQ ID NO: 1) encoding human BSSL is disclosed by Lidberg et al. (1992) in U.S. Pat. No. 5,616,483 (Astra AB). Web site: http://www.delphion.com/details?pn=US06525241__

Fatty acid polyol ester-coated lipase complex immobilized on insoluble matrix Inventor(s): Basheer; Sobhi (Sakhnine, IL) Assignee(s): Enzymotec, Ltd. (Nazareth Illit, IL) Patent Number: 6,605,452 Date filed: March 23, 1999 Abstract: A lipase preparation is prepared containing a surfactant-coated lipase complex immobilized onto an insoluble matrix. A preferred surfactant is a fatty acid polyol ester such as sorbitan monostearate (SMS). The lipase preparation may be provided in granulated form or in an organic solvent, and can be used in esterifying, inter-esterifying, trans-esterifying and alcoholysing reactions with no added water. The
172
Lipase
lipase preferably has 1,3-positional specificity with respect to triacylglycerols, and the insoluble matrix may be modified with a fatty acid derivative. A lipase in aqueous medium is contacted with a surfactant to coat the lipase with the surfactant, and the coated lipase is immobilized onto an insoluble matrix to produce the lipase preparation which may be dried such as by freeze drying. Alternatively, the lipase may be first contacted with the insoluble matrix, and thereafter with the surfactant. Excerpt(s): The present invention relates to an insoluble matrix immobilized surfactantcoated lipase complex, to a method of preparing same and to the use of same as a biocatalyst for catalyzing, for example, inter- and/or trans-esterification of oils and fats in hydrophobic organic media. The novel procedures include two steps. In the first step, the enzyme is activated by being coated with a surfactant. In the second step, the enzyme is immobilized on the matrix of choice. These steps can be executed in any order. Enzymatic modification of the structure and composition of oils and fats is of great industrial and clinical interest. This process is accomplished by exploiting regiospecific lipases in inter-esterification and/or trans-esterification reactions utilizing fats or oils as substrates (Macrea, A. R., 1983, J. Am. Oil Chem. Soc. 60: 291-294). Using an enzymatic process, it is possible to incorporate a desired fatty acyl group on a specific position of a triacylglycerol molecule, whereas conventional chemical inter-esterification does not possess regio-specificity. Conventionally, chemical reactions are promoted by sodium metal, sodium alkoxide or cobalt chloride that catalyze acyl migration among triglyceride molecules, leading to the production of triglycenrdes possessing randomly distributed fatty acyl residues (Erdem-Senatalar, A., Erencek, E. and Erciyes, A. T., 1995, J. Am. Oil Chem. Soc. 72: 891-894). Web site: http://www.delphion.com/details?pn=US06605452__ •
Gastric emptying-promoting composition Inventor(s): Kondo; Takaharu (Kani, JP) Assignee(s): Amano Pharmaceutical Co., Ltd. (Aichi, JP) Patent Number: 6,656,464 Date filed: December 21, 1998 Abstract: Compositions having an effect of promoting gastric emptying. These compositions comprise a lipase which was found to have an effect of promoting gastric emptying together with lipase activity-free ingredient(s) acting on the digestive tracts such as a prokinetic, a histamine H.sub.2 receptor antagonist, a proton pump inhibitor and/or a stomachic ingredient. They are efficaciously employed as medicaments for ameliorating or treating chronic gastrointestinal symptoms such as sinking feelings, heartburn and heaviness in the stomach, i.e., complaints about the digestive tracts. Excerpt(s): This invention relates to compositions having an effect of promoting the gastric emptying. More particularly, it relates to medicaments containing a lipase preparation which is a digestive enzyme. The medicaments of the present invention are efficaciously used in ameliorating or treating chronic gastrointestinal symptoms such as sinking feelings, heartburn and heaviness in the stomach, i.e., complaints about the digestive tracts. Even healthy people often notice subjective gastric symptoms (sinking feelings, heartburn, anorexia, etc.) in the everyday life. These symptoms are caused by stress, overeating, excessive intake of alcoholic drinks and intake of drugs. Moreover, it is frequently observed that the stress of the complicated current social structure or side effects of medicaments result in chronic gastrointestinal symptoms such as sinking

Human lipase proteins, nucleic acids encoding them, and uses of both of these Inventor(s): Kapeller-Libermann; Rosana (Chestnut Hill, MA), Khodadoust; Mehran (Chestnut Hill, MA) Assignee(s): Millennium Pharmaceuticals, Inc. (Cambridge, MA) Patent Number: 6,558,936 Date filed: October 1, 1999 Abstract: The invention provides isolated nucleic acids encoding human lipase proteins and fragments, derivatives, and variants thereof. These nucleic acids and proteins are useful for diagnosis, prevention, and therapy of a number of human and other animal disorders associated, for example, with aberrant lipid metabolism or aberrant pancreatic activity. The invention also provides antisense nucleic acid molecules, expression vectors containing the nucleic acid molecules of the invention, host cells into which the expression vectors have been introduced, and non-human transgenic animals in which a nucleic acid molecule of the invention has been introduced or disrupted. The invention still further provides isolated polypeptides, fusion polypeptides, antigenic peptides, and antibodies. Diagnostic, prognostic, screening, and therapeutic methods involving use of compositions of the invention are also provided. The nucleic acids and polypeptides of the present invention are useful as modulating agents in regulating a variety of cellular processes relating to mono-, di-, and triglyceride metabolism and pancreatic function. Excerpt(s): Lipids are esters of long chain fatty acids (generally C.sub.14 to C.sub.24 saturated and unsaturated fatty acids in animal fats) and polyols such as glycerol, glycerol phosphates, alkyl glyceryl ethers, glycerol phosphoryl-choline, glycerol phosphoryl-serine, glycerol phosphoryl-ethanolamine, and the like. Lipids, in the form of cell membranes and fats, for example, constitute a significant proportion of animal body weight (e.g., about 5% to 25% of body weight in normal humans). Lipids are not water-soluble, and generally do not cross biological membranes efficiently by simple diffusion. Dietary lipids are taken up primarily by hydrolysis of fatty acyl moieties from their corresponding polyol moiety and diffusion of the two moieties across the gut wall (although limited uptake of intact lipids occurs). Following absorption, lipids are reformed by reestablishment of ester bonds between polyol and fatty acyl moieties, and lipids are delivered throughout the body in esterified form (generally in lipoproteincontaining particles such as chylomicrons, very low, intermediate, low, and high density lipoprotein particles, and the like). Prior to uptake by cells (either for storage or for metabolism), lipids must again be hydrolyzed in order to facilitate passage across the cell membrane. Thus, enzymes which catalyze formation and hydrolysis of the ester bonds between fatty acyl moieties and polyol moieties of lipids must be present at several physiological locations, and the particular activities catalyzed by these enzymes (`lipases` ) varies depending on the physiological location and function of the enzyme. A number of lipase enzymes have been characterized in various organisms, including in humans. However, it is far from clear that all physiologically relevant lipases have been discovered or characterized. The present invention provides novel nucleotide and amino acid sequence information corresponding to one or more human lipases.

Immobilization of enzymes on particulate porous carriers for use in organic mediums Inventor(s): Christensen; Morten Wurtz (Lyngby, DK), Kirk; Ole (Virum, DK), Pedersen; Christian (Roedovre, DK) Assignee(s): Novozymes A/S (Bagsvaerd, DK) Patent Number: 6,582,942 Date filed: August 29, 2000 Abstract: An immobilized enzyme is prepared for use in organic mediums essentially devoid of free water. An enzyme-containing liquid medium is contacted with a particulate porous carrier which preferably has a particle size of 200-1000.mu.m and a surface area of 20-1000 m.sup.2 /g to adsorb the enzyme on the carrier, and volatile components of the liquid medium contained by the carrier are removed. The carrier may have a hydrophilic surface, and an amount of liquid medium is used to prevent agglomeration of the carrier. Alternatively, the carrier has a hydrophobic surface, and the addition of a hygroscopic substance suppresses agglomeration of the carrier by absorbing excess liquid. The hygroscopic substance may be removed during the removal of volatile components. Contacting of the enzyme-containing liquid and carrier can be in a fluidized bed where immobilization and removing volatile components are conducted simultaneously, or contacting can be in mixer followed by removing volatile components in a fluidized bed. The enzyme-containing liquid may be atomized onto the carrier in the fluidized bed or in the mixer. Enzymes immobilized include lipase, and the immobilized lipase can be used in trans-esterification reactions. Excerpt(s): The invention relates to a process for producing an immobilized enzyme preparation for use in a mainly organic medium essentially devoid of free water, and use of the immobilized enzyme preparation for organic synthesis. Immobilized enzymes are known to be used for organic synthesis. The most commonly immobilized enzymes are lipases used for esterification reactions in mainly organic media essentially devoid of free water. Web site: http://www.delphion.com/details?pn=US06582942__

Lipase inhibiting compositions Inventor(s): de Smidt; Passchier Christiaan (Pamplona, ES), Hadvary; Paul (Biel-Benken, CH), Lengsfeld; Hans (Basel, CH), Schmid; Marcel (Reinach, CH), Small; Donald MacFarland (Quincy, MA), Steffen; Hans (Liestal, CH), Tardio; Joseph (St. Louis, FR) Assignee(s): Hoffman-La Roche Inc. (Nutley, NJ) Patent Number: 6,703,369 Date filed: September 13, 2000 Abstract: A pharmaceutical composition contains at least one inhibitor of lipases and at least one fatty acid ester of polyol. In this composition, the fatty acid ester has a melting point above the body temperature and the polyols are chosen from the group consisting of sugars, sugar derivatives, and mixtures thereof. Excerpt(s): The present invention relates to pharmaceutical compositions comprising at least one lipase inhibitor. Lipase inhibitors include lipstatin and orlistat. The latter is also known as tetrahydrolipstatin or THL and is derived from a natural product excreted by Streptomyces toxytricini. This class of compounds was found to exhibit in vitro as well as in vivo activity against various lipases, such as lingual lipase, pancreatic lipase, gastric lipase, and carboxylester lipase. Its use for the control or prevention of obesity and hyperlipidemia is described, for instance, in U.S. Pat. No. 4,598,089. Orlistat is currently administered at doses of 120 mg per meal and dosing is independent of the body mass of the human subject. Orlistat acts locally in the gastrointestinal (GI) tract and prevents lipase from digesting triglycerides and subsequently inhibits the formation of absorbable lipid degradation products. For this reason, systemic availability of the lipase inhibitors is not required; instead, local residence in the gastrointestinal tract is preferred.

(product of Novo Nordisk A/S). There is an ever existing need for providing novel lipases with improved properties, in particular improved washing properties in commercial detergents, including detergents with a high content of anionic surfactants. The present invention relates to such novel lipases. Web site: http://www.delphion.com/details?pn=US06624129__ •
Lipase-catalysed esterification of marine oil Inventor(s): Haraldsson; Gudmundur G. (Reykjavik, IS), Kristiansson; Bj.o slashed.rn (Reykjavik, IS), Thorstad; Olav (Heistad, NO) Assignee(s): Norsk Hydro ASA (Oslo, NO) Patent Number: 6,518,049 Date filed: November 2, 2001 Abstract: Marine oil compositions which contain EPA and DHA as free acids are esterified with glycerol in the presence of a lipase catalyst under reduced pressure and essentially organic solvent-free conditions to form a free fatty acid fraction enriched in at least one of EPA and DHA. Excerpt(s): This invention relates to the lipase catalysed esterification of marine oils. It is well known in the art to refine oil products of various kinds, including marine oils, with the aid of lipase catalysts whose specificity under the refining conditions employed enhances the recovery of a desired product. For example, in PCT/WO95/00050 we disclosed a process for treating an oil composition containing saturated and unsaturated fatty acids in the form of triglycerides to transesterification reaction conditions with a C.sub.1-6 alcohol such as ethanol under substantially anhydrous conditions in the presence of a lipase active to preferentially catalyse the transesterification of the saturated and monounsaturated fatty acids. With the preferred lipases, Pseudomonas sp. lipase (PSL) and Pseudomonas fluorescens lipase (PFL) it was possible to prepare from marine oil sources concentrates containing more than 70% by weight of the commercially and therapeutically important omega-3 polyunsaturated fatty acids EPA (eicosapentaenoic acid, C20:5) and DHA (docosahexaenoic acid, C22:6) in the form of glycerides.

Method of producing activated lipase Inventor(s): Ichikawa; Sosaku (Ibaraki, JP), Maruyama; Tatsuo (Ibaraki, JP), Nabetani; Hiroshi (Ibaraki, JP), Nakajima; Mitsutoshi (Ibaraki, JP), Seki; Minoru (Tokyo, JP) Assignee(s): Bio-Oriented Technology Research Advancement Institution (), Japan as represented by Director of National Food Research Institute (Ibaraki, JP), Ministry of Agriculture, Forestry and Fisheries (Tokyo, JP) Patent Number: 6,528,293 Date filed: October 12, 1999 Abstract: A method is disclosed for activating a lipase by adding a solution of lipase in an aqueous buffer at a pH near neutrality to an organic phase, e.g., tetradecane. Under these conditions lipase is activated as a function of an organic-and-water boundary surface between the organic and water phases. The lipase that is activated in this manner remains active even after lyophilization to remove the water and the organic phase. This activated lipase efficiently catalyzes a fat reforming reaction in non-aqueous and nano-aqueous conditions. Excerpt(s): The present invention relates to a method of activating of an enzyme such as lipase, etc., to reaction of such activated enzyme including reformation of fat, and further to a method of deactivating the enzyme once it is activated. Conventionally, the production of many useful products has been achieved with use of enzymes. In particular, lipase was widely used for reforming fat so as to produce edible oil, soap, glycerin, dairy or milk products, etc., because of the versatility thereof. Today where resources, energy, and ecological problems are discussed daily on a global scale, many expectations are applied to efficient and safe production of important materials (i.e., fatty acids, etc.) in the chemical industry, as well as to high-performance materials to which much attention is paid in the fields of pharmaceuticals and foodstuffs, with the use of the enzyme which can be represented by lipase.

Method of reducing gastrointestinal side effects associated with orlistat treatment Inventor(s): Barbier; Pierre (Rixheim, FR), Hadvary; Paul (Biel-Benken, CH), Lengsfeld; Hans (Basel, CH) Assignee(s): Hoffmann-La Roche Inc. (Nutley, NJ) Patent Number: 6,756,364 Date filed: July 25, 2001 Abstract: A pharmaceutical combination or composition containing a lipase inhibitor, preferably orlistat, and a bile acid sequestrant is useful for treating obesity. Excerpt(s): The present invention relates to pharmaceutical combinations, compositions and methods for treating obesity. Bile acids are synthesized in the liver and enter the bile as glycine and taurine conjugates. They are released in salt form in bile during digestion and act as detergents to solubilize and consequently aid in digestion of dietary fats. Following digestion, bile acid salts are mostly reabsorbed in the ileum, complexed with proteins, and returned to the liver through the hepatic portal vein. The small amount of bile acid salts which are not reabsorbed by active transport are excreted via the distal ileum and large intestine as a portion of fecal material. Reducing reabsorption of bile acids within the intestinal tract can lower levels of bile acid circulating in the
178
Lipase
enterohepatic system thereby potentially reducing emulsification in the upper intestinal tract of dietary fat and reducing intestinal absorption of fat soluble drugs. One method of reducing the amount of bile acids that are reabsorbed, is oral administration of compounds that sequester the bile acids within the intestinal tract and cannot themselves be absorbed. Orlistat (also known as tetrahydrolipstatin and sold under the brand name XENICAL.RTM.) is a potent inhibitor of gastrointestinal lipases, i.e. lipases that are responsible for breaking down ingested fat (gastric lipase, carboxylester lipase, pancreatic lipase). As a consequence of this, unabsorbed fat is excreted in the feces. Pancreatic lipase is the key enzyme for the hydrolysis of dietary triglycerides. Triglycerides that have escaped hydrolysis are not absorbed in the intestine. Pharmacological studies with human patients demonstrate potent inhibition of fat absorption and medically relevant reduction of body weight was achieved using lipase inhibitors. However, in a subgroup of the patients, unpleasant gastrointestinal side effects such as oily spotting, fatty/oily stools, fecal urgency, increased defecation and fecal incontinence are observed. Accordingly, there is a need in the art for lipase inhibiting compositions that minimize or suppress the side effects caused by inhibitors of digestive lipases.

Method of stabilizing graham flour, and cracker produced from said flour Inventor(s): Adrianson; Tim Michael (Oak Ridge, NJ), Gannon; Diane Louise (Perrysburg, OH), Howey; Edward Douglas (Toledo, OH), Levine; Harold Ira (Morris Plains, NJ), Mozeke; Patricia Ann (Bedminster, NJ), Slade; Louise (Morris Plains, NJ), Wilhelm; Carolyn Louise (Hackettstown, NJ) Assignee(s): Kraft Foods Holdings, Inc. (Northfield, IL) Patent Number: 6,616,957 Date filed: November 28, 2000 Abstract: A process is provided for making reduced fat, low fat or no-fat graham-based crackers and flour for the production thereof. The process for making the flour includes providing whole wheat berries having a moisture content of from about 15% by weight to about 20% by weight, radiating the berries with infrared (IR) energy, optionally maintaining the berries at an elevated temperature of from about 80.degree. C. to about 110.degree. C. for a period of time up to about one hour, and cooling, drying and comminuting the treated berries. The moisture content of the berries can be adjusted by moistening or tempering the berries prior to treatment with IR energy. The moisture content, optional tempering conditions, amount of irradiated IR energy, the elevated temperature, and the various treatment periods are sufficient to inactivate lipase and lipoxygenase in the berries yet insufficient to gelatinize more than about 20% of the starch in the berries. The graham flour has excellent shelf-life stability, and can be used to obtain machinable doughs on a mass production, continuous basis. Baked goods made from the flour have a surprisingly crunchy texture. Excerpt(s): The present invention relates to processes for making graham-based flours which exhibit low rancidity and extended shelf-life and to baked goods having a crunchy texture made from such flours. The present invention also relates to reduced fat, low fat, or no-fat baked goods, such as graham crackers and snacks, produced from such flours. Whole cereal grains and graham flour provide a high dietary fiber content but also provide natural lipids and enzymes, such as lipase and lipoxygenase (LPO), which may deleteriously interact during storage. The interaction of the lipids and
Patents 179
enzymes can lead to rancidity problems such as off-flavors and odors in baked goods made from graham flour. Generally, to avoid rancidity problems in baked goods, graham flour is employed which is less than about ten days old. Rancidity in cereal products may be due to hydrolytic (enzymatic) or oxidative degradation reactions, or both. Often, hydrolysis may predispose products to subsequent oxidative rancidity. Nature has provided a number of protective features in seeds to prevent rancidity and spoilage, enabling seeds to survive periods of adverse conditions before attaining an appropriate environment for germination and growth. Rancidity is less likely to develop when lipid materials, for example, seed oil, are unable to interact with reactants or catalysts such as air and enzymes. One protective feature in cereal grains is the provision of separate compartments for storing lipids and enzymes so that they cannot interact.

Method of treating high plasma cholesterol levels Inventor(s): Hadvary; Paul (Biel-Benken, CH), Lengsfeld; Hans (Basel, CH), Steffen; Hans (Liestal, CH) Assignee(s): Hoffmann-La Roche Inc. (Nutley, NJ) Patent Number: 6,562,329 Date filed: July 25, 2001 Abstract: A method prevents or treats diseases associated with high plasma cholesterol levels. In addition, this method reduces plasma cholesterol levels. The method comprises administering a lipase inhibitor, e.g. orlistat, and a pharmaceutically acceptable bile acid sequestrant. Excerpt(s): The present invention relates to a new method for the prevention and treatment of diseases associated with high plasma cholesterol levels (hypercholesterolemia). Bile acid sequestrants have been proposed for use in lowering circulating blood cholesterol levels. Biologically, cholesterol is eliminated from the body by conversion to bile acids and excretion as neutral steroids. Bile acids are synthesized from cholesterol in the liver and enter the bile as glycine and taurine conjugates. They are released in salt form in bile during digestion and act as detergents to solubilize and consequently aid in digestion of dietary fats. Following digestion, bile acid salts are mostly reabsorbed in the ileum, complexed with proteins, and returned to the liver through hepatic portal veins. The small amount of bile acid salts which are not reabsorbed by active transport are excreted via the distal ileum and large intestine as a portion of fecal material. Bile acids are synthesized from cholesterol transported in lipoproteins in the liver. Therefore, reabsorption of bile acids, which can be present as the corresponding salts or conjugates, from the intestine conserves lipoprotein cholesterol in the bloodstream. As such, reducing reabsorption of bile acids within the intestinal tract can lower levels of bile acid circulating in the enterohepatic system thereby promoting replacement of bile acids through synthesis from cholesterol, in the liver. The result is a lowering of circulating blood cholesterol levels. One method of reducing the amount of bile acids that are reabsorbed, is oral administration of compounds that sequester the bile acids within the intestinal tract and cannot themselves be absorbed. The sequestered bile acids consequently are excreted. As a consequence of gastrointestinal lipase inhibition, unabsorbed fat is egested in the faeces. Pancreatic lipase is the key enzyme for the hydrolysis of dietary triglycerides. Triglycerides, which have escaped hydrolysis are not absorbed in the intestine. Orlistat

Nutritional composition for improving the efficacy of a lipase inhibitor Inventor(s): Portman; Robert (Fair Haven, NJ) Assignee(s): Pacific Health Laboratories, Inc. (Woodbridge, NJ) Patent Number: 6,558,690 Date filed: December 14, 2001 Abstract: A nutritional intervention composition is provided for enhancing the efficacy of an orally administered lipase inhibitor comprising a protein component of at least a glycomacropeptide or caseinmacropeptide, at least one C.sub.12-18 fatty acid comprising at least oleic acid and a fiber preferably comprising both soluble and insoluble fibers. The composition is administered concurrently with the lipase inhibitor to negate the action of the latter in inhibiting the release of cholecystokinin (CCK) which, in turn, reduces the feeling of satiety and stimulates appetite. These effects are all countered by the subject compositions which stimulate release of CCK and increase the level of bile in the intestine. These effects achieved by the subject nutritional intervention compositions, while not directly increasing the effectiveness of the lipase inhibitor, nonetheless enhance its efficacy. Excerpt(s): The present invention relates to a nutritional composition that is taken with a lipase inhibitor prior to the consumption of a meal which enhances the efficacy of the lipase inhibitor by increasing CCK levels and enhancing and extending post meal satiety. Lipase inhibitors are being prescribed for weight reduction in obese patients. A lipase inhibitor functions by inhibiting gastric and pancreatic lipases, thereby rendering them temporarily unavailable to hydrolyze dietary fat in the form of triglycerides into absorbable free fatty acids and monoglycerides. The undigested triglycerides are excreted without being metabolized. As the undigested triglycerides are not absorbed, the resulting caloric deficit may have a positive effect on weight control. Clinical studies have shown that lipase inhibitors, taken prior to consuming a meal containing a moderate amount of fat, significantly increase the excretion of fat. In this fashion, a lipase inhibitor produces weight loss by blocking a percentage of fat that would normally be absorbed. Indeed, it has been shown that lipase inhibitors, such as the prescription drug tetrahydrolipstatin, generically known as Orlistat, are effective in obesity management. Cholecystokinin (CCK) is a peptide released following the consumption of food which is a major satiety signal in humans. Studies have shown that individuals receiving CCK demonstrate a reduction in caloric intake of from about 1622%. Although the full mechanism whereby CCK exerts its effect on satiety is not known, there appear to be two components, a central component involving CCK receptors in the brain and a peripheral component involving the stomach and small intestine. When food is consumed, CCK releasing protein (CCKRP) is released in the small intestine. CCKRP stimulates CCK release from intestinal cells. Web site: http://www.delphion.com/details?pn=US06558690__

The present invention further relates to a process for the production of Percyquinnin and to the use of Percyquinnin and its pharmaceutically acceptable salts as pharmaceuticals, in particular to their use as inhibitors of lipase. Excerpt(s): This invention relates to a compound named Percyquinnin, its pharmaceutically acceptable salts and derivatives, and to methods for obtaining the compound. One method of obtaining the compound is by cultivation of the Basidiomycete Stereum complicatum, ST 001837 (DSM 13303). The present invention further relates to a process for the production of Percyquinnin, to the fungus ST 001837 (DSM 13303), to the use of Percyquinnin and its pharmaceutically acceptable salts and derivatives as pharmaceuticals, in particular to their use as lipase inhibitors, and to pharmaceutical compositions comprising Percyquinnin or a pharmaceutically acceptable salt or derivative thereof. Lipid metabolism normally keeps a delicate balance between synthesis and degradation. When the balance is upset, hyperlipidemia may occur, which in turn can cause atherosclerosis, hypertension, diabetes etc. Modulators of lipid metabolism may be expected to be useful in controlling these and other disorders. Inhibition of lipolysis in non-insulin-dependent diabetes mellitus (NIDDM) is supposed to reduce hyperglycemia. The initial event in the utilization of fat as an energy source is the hydrolysis of triacylglycerol by lipases, e.g., hormone sensitive lipase, and monoacylglycerol lipase. Hydrolyses of triacylglycerols may lead to increased levels of glycerol and fatty acids in the blood. Lipase inhibitors may be expected to reduce both plasma fatty acid levels and hyperglycemia with reduced side effects. Web site: http://www.delphion.com/details?pn=US06596518__

Excerpt(s): The present invention relates to compositions containing lipase inhibitors, e.g. orlistat, and the use of said compositions for treating, reducing or preventing functional dyspepsia after ingestion of meals, especially of fat containing or fat rich meals. Functional dyspepsia is a condition characterized by sensations of gastric

fullness, nausea, bloating, gastric distress, etc., after intake of meals (even small meals), especially after intake of fat containing or fat rich meals. A large number of people are afflicted by this condition, continuously or more regularly in response to fat rich meals or fat rich meal items. The arrival of lipid in the small intestinal lumen normally causes gastric relaxation, modulation of phasic motor activity, and pancreaticobiliary secretion. However, in patients with functional dyspepsia, lipids often provoke postprandial symptoms. Gastric and pancreatic lipases in the intestinal lumen hydrolyze triglycerides to free fatty acids, which may act on brain centers involved in dyspeptic symptoms.

Plant lipases Inventor(s): Cahoon; Edgar B. (Wilmington, DE) Assignee(s): E. I. du Pont de Nemours and Company (Wilmington, DE) Patent Number: 6,673,988 Date filed: September 22, 2000 Abstract: This invention relates to an isolated nucleic acid fragment encoding a lipase. The invention also relates to the construction of a chimeric gene encoding all or a portion of the lipase, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the lipase in a transformed host cell. Excerpt(s): This invention is in the field of plant molecular biology. More specifically, this invention pertains to nucleic acid fragments encoding lipases in plants and seeds. True lipases act at an oil-water interface; they constitute a ubiquitous group of enzymes catalyzing a wide variety of reactions, many with industrial potential. Lipases have been grouped into families according to their amino acid sequence, enzymatic specificity, and differential expression. A family of lipolytic enzymes with members in Arabidopsis thaliana, rice and corn has been described (Brick et al. (1995) FEBS Lett. 377:475-480). It is possible to change the structure of fats and oils by manipulating the lipase specificity ending with products containing the desired fatty acid at a specific position on the glycerol backbone. Lipases play important roles in pathogen defense and in activating membrane formation. Web site: http://www.delphion.com/details?pn=US06673988__

It is advantageous and possible to obtain the lipase on a large scale relatively simply by fermentation processes. Preference is given to employing lipases from Pseudomonas species. Excerpt(s): The invention relates to a process for polycondensation of organic silicon compounds in the presence of an enzyme. Silicones and silicates are of industrial-scale importance. Silicates are employed, for example, as phase material in chromatography. There are numerous processes for their preparation. Processes leading to amorphous silicates, for example, start from orthosilicic acid which is condensed in aqueous solution with acid or base catalysis (A. F. Holleman, E. Wiberg, Lehrbuch der Anorganischen Chemie [Textbook of Inorganic Chemistry], Walter de Gruyter Verlag, Berlin N.Y. 1985, 91st-100th edition, pp. 757-764). Silicones can be prepared by condensation of silanols, silanediols and silanetriols (A. F. Holleman, E. Wiberg, Lehrbuch der Anorganischen Chemie, Walter de Gruyter Verlag, Berlin N.Y. 1983, 91st100th edition, pp.786-788). In novel processes developed in the last few years it is possible to condense organic silicon compounds under mild conditions. Enzymes are employed as catalysts. The reactions can be carried out at from pH 6 to pH 8. In 1998 a suitable enzyme has been isolated for the first time from a marine sponge, as described in J. N. Cha, K. Shimizu, Y. Zhou, S. C. Christiansen, B. F. Chmelka, G. D. Stucky, D. E. Morse, Proc. Natl. Acad. Sci. USA 1999, 96, 361-365. The enzyme is composed of three subunits, the so-called silicateins. Extracting the enzyme is relatively costly. Besides polycondensation in buffer solution, the organic silicon compounds (EtO).sub.4 Si and (EtO).sub.3 SiPh have been converted directly using air-dried enzyme. Moreover, WO 00/35993 describes employing synthetic homopolymers composed of cysteine and block polypeptides composed of lysine and cysteine for polycondensation of silicon alkoxides, metal alkoxides and derivatives thereof into silicates, polysiloxanes and polymetaloxanes. It is an object of the present invention to provide a further process for the polycondensation of organic silicon compounds, which can be carried out at from pH 6 to 8, and to find a suitable catalyst for this reaction.

Methods of making (all-rac)-.alpha.-tocopherol and (all-rac)-.alpha.-tocopherol acetate are also provided. The major commercial form of vitamin E is its acetate derivative, synthesized by acetylation of (all-rac)-.alpha.tocopherol, e.g. with acetic anhydride. Industrial syntheses of (all-rac)-.alpha.tocopherol are based on the condensation of trimethylhydroquinone (TMHQ) with isophytol, phytol or a derivative thereof, such as a phytyl halide. TMHQ is normally obtained from 2,3,6-trimethylphenol which is expensive, however, and acidic catalysts have to be used for the condensation of the TMHQ with isophytol, phytol or a derivative thereof, such as a phytyl halide.

Processes for synthesis and purification of nondigestible fats Inventor(s): Howie; John Keeney (Oregonia, OH), Trout; James Earl (West Chester, OH) Assignee(s): The Procter & Gamble Co. (Cincinnati, OH) Patent Number: 6,566,124 Date filed: September 15, 2000 Abstract: A process for removing digestible fat from a crude reaction mixture comprising nondigestible fat and at least one digestible fat selected from the group consisting of digestible fats having fatty acid chains, comprising the steps of: (1) treating the crude reaction mixture with an aqueous solution comprising lipase at a pH sufficient to obtain soaps from the fatty acid chains; and (2) removing the soaps. Excerpt(s): This patent application cross-references and incorporates by reference copending patent application "Synthesis of Higher Polyol Fatt) Acid Polyesters by Transesterification", filed in the name of Trout et al. and co-pending application "Improved Processes for Synthesis and Purification of Nondigestible Fats Using Lipase", filed in the name of Trout et al., both applications filed on the same date as this application. This invention relates to low-temperature atmospheric pressure processes for the purification of polyol fatty acid polyesters or other nondigestible fats that have a digestible fat, such as a triglyceride, in the final product. More particularly, this invention relates to processes for purifying nondigestible fats from a crude reaction mixture by use of an aqueous solution comprising lipase. The food industry has recently focused attention on polyol fatty acid polyesters for use as low-calorie fats in food products. Triglycerides (triacylglycerols) constitute about 90% of the total fat consumed in the average diet. One method by which the caloric value of edible fat could be lowered would be to decrease the amount of triglycerides that is absorbed in the human
186
Lipase
system, since the usual edible triglyceride fats are almost completely absorbed (see Lipids, 2, H. J. Deuel, Interscience Publishers, Inc., New York, 1955, page 215). Low calorie fats which can replace triglycerides are described in Mattson, et al., U.S. Pat. No. 3,600,186. Mattson, et al. disclose low calorie, fat-containing food composition in which at least a portion of the triglyceride content is replaced with a polyol fatty acid ester having at least four fatty acid ester groups, with each fatty acid having from eight to twenty-two carbon atoms.

Product for topical application containing a lipase and a hydroxy acid precursor Inventor(s): Guth; Gerard (Montmorency, FR), Maurin; Emmanuelle (L'Isle-Adam, FR), Sera; Daniel (L'Hay les Roses, FR) Assignee(s): L'Oreal (Paris, FR) Patent Number: 6,488,928 Date filed: October 24, 1995 Abstract: The present invention concerns a product for topical application, capable of releasing a hydroxy acid on the skin, containing a lipase as enzyme and at least one precursor of the hydroxy acid. The precursor is an ester of the hydroxy acid, containing at least one ester functional group having a saturated or unsaturated, linear or branched chain and from 2 to 25 carbon atoms. According to a preferred form, the precursor and the lipase are packaged so as not to be in contact with one another until the time of application to the skin. Excerpt(s): The present invention concerns a product for topical application which is capable of releasing a hydroxy acid on the skin, and the use thereof in imparting softness to the skin, including the scalp. The present invention also concerns a process for the cosmetic and/or dermatological treatment of the skin, particularly for the treatment of acne, wrinkles and fine lines, and the use of the present product therein. Hydroxy acids are increasingly used in the cosmetics or dermatological fields for caring for the face and/or the body, and more especially, for giving the face a luminous and radiant complexion, and therefore a healthy, smooth and younger appearance, and for causing the disappearance of blackheads due to acne. Unfortunately, hydroxy acid compounds are generally provided in compositions having a pH of less than or equal to 4, for the purpose of maintaining the activity of these acids. The application of these compositions to the skin has the major disadvantage of causing stinging, itching and stabbing pains, which can produce great discomfort. The use of these acidic compositions for users with sensitive skin is therefore often out of the question. Web site: http://www.delphion.com/details?pn=US06488928__

Solid detergents with active enzymes and bleach Inventor(s): Scepanski; William H. (Bloomington, MN) Assignee(s): Sunburst Chemicals, Inc. (Bloomington, MN) Patent Number: 6,777,383 Date filed: March 27, 2002
Patents 187
Abstract: A detergent composition is described which is a solid homogeneous, evenly dispersed composition containing anionic and nonionic surfactants, soil suspending agents, chelating or sequestering agents, and alkaline builders. The detergent compositions will contain either active enzymes, an oxygen releasing bleaching agent or both. The active enzymes can be protease, amylase or lipase enzymes. Said composition can be used for laundry washing or hard surface cleaning. Manufacturing procedures and methods of use are described. Excerpt(s): The invention relates to solid detergents. The invention relates more specifically to solid detergents having enzymes and stable oxygen-releasing bleaching agents that are stable upon storage of the detergent. Detergent systems for laundry, warewashing, hard surface cleaning (food plant, institutional, industrial, transportation), and numerous other similar applications have long been available where powders are manually scooped into water and dissolved. The resulting detergent solution is applied to the surface or article being cleaned. Also, concentrated liquid detergents have been found to be highly desirable by certain consumers. Important considerations in the selection of a detergent composition include ease of handling, cleaning ability and stability of the product during storage. The basic ingredients of a detergent are surfactants, which emulsify and suspend soils, and alkaline builders, which saponify fats and oils. One advantage of powder detergents is the high concentrations of active ingredients because few or no inert ingredients are required. In powder detergents, high levels of inorganic or organic salts can be used to raise alkalinity and soften water by chelating or sequestering water hardness ions. The powdered detergents can be used to provide oxidizing agents (bleaches) or reducing agents (for example, sodium thiosulfate) and granular enzyme materials, which can be blended into free flowing powder detergents. The oxidizing or reducing agents and the enzymes are stable in the powdered detergents with no significant loss of activity on extended storage.

Stabilized rice bran deer feed, attractant and browse supplement Inventor(s): Chastain; Jason N. (Stuttgart, AR) Assignee(s): Producers Rice Mill, Inc. (Stuttgart, AR) Patent Number: 6,616,924 Date filed: June 2, 2000 Abstract: Deer attractant and feed comprising stabilized rice bran and calcium carbonate is disclosed. Limestone is added to the rice during the milling process. The residue from this process, rice bran and a small amount of pulverized limestone, is the cooked in an extruder, resulting in stabilized rice bran. The extrusion process destroys lipase activity and reduces the free fatty acid content to under 4%. The product contains about 12.5% or more protein, and preferably has a 2:1 ratio of calcium to phosphorous. Because of the balanced nutritional analysis and the addition of calcium carbonate to the feed, the product aids in promoting overall deer growth as well as bone growth in bucks. The product also acts as a deer attractant, moving deer toward sources of adequate food supplies and away from cultivated gardens and crops. Excerpt(s): Traditional deer feeds and attractants, such as corn and salt, are not optimal for deer's health. Regulations have been enacted, such as those adopted by the Texas A&M Animal Health Divisions, concerning the use of feed grains contaminated by
188
Lipase
aflatoxins. Needs exist for deer feeds and attractants that are beneficial to deer and herds. The present invention is for deer attractant and feed comprising mostly of stabilized rice bran. Web site: http://www.delphion.com/details?pn=US06616924__ •
Synthesis of B-keto esters Inventor(s): Cordova; Armando (La Jolla, CA), Janda; Kim D. (La Jolla, CA) Assignee(s): The Scripps Research Institute (La Jolla, CA) Patent Number: 6,642,035 Date filed: January 26, 2001 Abstract:.beta.-keto esters are prepared by way of a lipase-catalyzed transesterification. The synthetic methodology provides a simple scheme for the synthesis of optically active.beta.-keto esters that are useful building blocks and starting materials for natural product synthesis. Moreover, the methodology employs mild, solvent-free conditions. The methodology may also be employed for resolving racemic alcohols. Excerpt(s): The invention relates to the synthesis of.beta.-keto esters. More particularly, the invention relates to a highly chemo- and stereoselective synthesis of.beta.-keto esters via a polymer-supported lipase catalyzed transesterfication.beta.-keto esters are noteworthy in that they represent an important class of organic building blocks used in the synthesis of complex natural products (S. Benetti, et al., Chem Rev. 1995, 95, 1065). A seemingly straight-forward method to prepare these molecules is through an alcohol based transesterification (J. G. Gilbert, et al., J. Org. Chem. 1988, 53, 449; D. F. Taber, et al., J. Org. Chem. 1985, 50, 3618). Yet the synthesis of allylic and propargylic.beta.-keto esters is not trivial by this route due to their acid/base lability and sigmatropic rearrangement of the.beta.-keto ester. To circumvent these problems a report has appeared describing the heating of alcohols with.beta.-keto esters in toluene (C. Mottet, et al., J. Org. Chem. 1999, 64, 138;). However, the reaction times were lengthy and yields variable for many of the substrates. Another mild method uses crystalline microporous nanosilicates (zeolites) as the catalyst for the transesterification in refluxing toluene to avoid potential side reactions, but here the yields were even lower compared to the former case (B. S. Balaji, et al., J. Chem. Soc. Chem. Commun. 1996, 707). Furthermore, none of these or any of the conventional methods display stereoselectivity or chemoselectivity between aliphatic alcohols or phenols. What is required is a general method of synthesizing.beta.-ketoesters either as racemates or as single enantiomers. What is required is a general method for resolving alcohol racemates. Candida antarctica lipase B (CALB) immobilized on a macroporous poly(propylene) resin (Novozym 435) catalyzed the transesterification of.beta.-keto esters under environmentally safe conditions. The reactions were performed by simply solubilizing the alcohols in methyl or ethyl.beta.-keto esters and then treating the reaction mixture with the lipase under reduced pressure. The.beta.-keto ester products were obtained in high yields (>90%) and CALB was chemoselective in the acylation of aliphatic alcohols in the presence of phenols. In addition, CALB was able to resolve sec-alcohols with high enantioselectivity. This is a general route to prepare.beta.-keto esters by lipase-catalyzed transesterification and it can be of ample use due to its mild, solvent-free conditions. Moreover, it also provides a simple protocol to produce optically active.beta.-keto esters that are useful building blocks and starting materials for natural product synthesis.

Lipase
inhibitor such as orlistat, and glucomannan such as konjac as well as methods for utilizing such compositions and kits for carrying out this method. Excerpt(s): The field of this invention is the field of combating obesity utilizing compositions containing lipase inhibitors. Adverse effects which occasionally are observed in patients treated with lipase inhibitors are anal leakage of oil (oily spotting) and fecal incontinence. Oily spotting results from physical separation of some of the ingested but unabsorbed dietary fat from the bulk of the fecal mass in the colon. In U.S. Pat. No. 5,447,953 it has been shown that by combining a lipase inhibitor with substantial amounts of water insoluble crude fibers, the inhibiting effect on fat absorption can be increased. International Patent Application WO 00/09123 demonstrates that by combining a lipase inhibitor such as orlistat with low amounts of chitosan or a derivative or a salt thereof, the phenomenon of anal leakage of oil can be strongly reduced. Various approaches to control oily leakage have been discussed. Among such strategies are i) use of a surfactant to stabilize the oil/water interface in order to prevent coalescence of the oil emulsion in the colon, ii) enhancing water viscosity in the colon to reduce both intensity and frequency of droplet-droplet interactions and by that reducing the probability of coalescence, iii) physical absorption of oil by a lipophilic compound, or iv) increasing the natural stool mass by facilitating bacterial growth in the colon.

Biotin-peg-substrate for a lipase assay Inventor(s): Fowler, Anne; (Forest Farm Estate, GB), Hawes, Calvin Richard; (Forest Farm Estate, GB), James, David Martin; (Forest Farm Estate, GB), Poulsen, Fritz; (Bagsvaerd, DK), Price-Jones, Molly Jean; (Forest Farm Estate, GB), Tornqvist, Hans; (Bagsvaerd, DK) Correspondence: Amersham Biosciences; Patent Department; 800 Centennial Avenue; Piscataway; NJ; 08855; US Patent Application Number: 20040014133 Date filed: December 9, 2002 Abstract: Disclosed is a compound of Formula (I), wherein: L is a linking agent; B is a binding agent; X is an atom or group suitable for attaching L to the glycerol chain; and R is a straight chain saturated or unsaturated alkyl group having from 8 to 30 carbon atoms, substituted with M' or M" wherein at least one of M' and/or M" is a detectable label. The compound can be used as a lipase substrate in a solid phase-based assay system, such as a scintillation proximity assay, to detect lipase enzyme activity. Excerpt(s): The present invention describes a novel substrate for use in an assay for lipase enzyme activity. In particular, this novel substrate can be labelled and used in a homogeneous assay. Lipases are enzymes that catalyse the hydrolysis of triacylglycerols in the first step in recovering stored fatty acids for energy production. The sequence of hydrolysis from the three positions on glycerol depends on the specificity of the particular lipase involved. Lipase enzyme activity is an important function and its strict regulation is necessary to ensure healthy metabolism. For example, lipases in adipose tissue are key enzymes for the release of major energy stores. Their activity is under hormonal control to ensure that triacylglycerol hydrolysis is balanced with the process of triacyglycerol synthesis to assure adequate energy stores and yet avoid levels of fatty acids becoming so high as to cause adverse effects.

Drugs and foods improving the quality of life and process for producing the same Inventor(s): Ando, Kunio; (Kanagawa, JP), Fukuda, Akio; (Tokyo, JP), Igusa, Kazuo; (Shizuoka, JP), Kawai, Juri; (Tokyo, JP), Ogasawara, Toshichika; (Shizuoka, JP), Suzuki, Seikichi; (Kanagawa, JP) Correspondence: Birch Stewart Kolasch & Birch; PO Box 747; Falls Church; VA; 220400747; US Patent Application Number: 20040018190 Date filed: May 23, 2003 Abstract: The present invention relates to drugs and foods produced by applying a method whereby a biological activity can be efficiently exerted in the case of orally administering a biologically active protein.The oral composition according to the present invention contains at least one biologically active protein as the active ingredient and has a means of controlling the release. According to the composition of the present invention, at least 10% of the active ingredient is delivered to the lower digestive tract while sustaining its activity. Namely, the biologically active protein is not degraded in the stomach but delivered to the small intestine, which makes it possible to ensure the exertion of its drug's effect exert a hitherto unknown effect. It is preferable that the biologically benefical active protein contained in the composition according to the present invention is lactoferrin, immunoglobulin, lysozyme, an amylase, a protease, a lipase or a digestive enzyme inhibitor. Excerpt(s): This invention relates to drugs and foods produced by applying a method whereby a biological activity can be efficiently exerted in the case of a biologically active protein is orally administered. Namely, the present invention relates to drugs and foods wherein orally administered biologically active proteins passe through the stomach without being activated and reach the digestive tract lower than the duodenum (i.e., the action site) while sustaining its biological activity. Further, the present invention relates to diseases which can be newly treated/prevented by these drugs or foods. The method according to the present invention, wherein a biologically active protein can be delivered to the action site without being degraded, is highly efficacious for exerting biological properties. The small intestinal mucosa, which controls the digestion and absorption of foods, has fine villi covering its surface and the villi are further coated with smaller villi. Owing to this structure, the surface area of the mucosa is extremely enlarged. According to one estimate, the surface area of the human digestive tract Is 1.5 times larger than a tennis court and the small intestine accounts for major part. It is said that 150 trillion enteric gastrointestinal microflora inhabit the inner cavity of the gastrointestinal tract which can be regarded as outside of the living body. Namely, the human body is in contact with the outside over such a large area and nothing but a thin
Patents 193
mucous layer is provided as a partition wall between the body and the outside. This thin mucous layer seemingly responds to various external stimulations. However, it is almost unclear how the mucosa responds to a stimulus coming into contact with it, which part of the mucosa accepts a stimulation, and so on. That is to say, the stimulation-response mechanism of the mucosa still remains unknown. Anyway, it is true that the digestive tract mucosa plays an extremely important role In vivo. As a good example of the response of the intestinal mucosa to a stimulation, the function of the mucosa as a barrier against the invasion of intestinal microflora may be cited. That is to say, intestinal microflora would scarcely invade beyond the barrier so long as an animal is in good health. Once an animal suffers stress due to a surgical operation, trauma, burn, etc. or dies, the intestinal microflora immediately begin to invade into its body beyond the mucous layer. In the normal state, it is therefore supposed that some protection mechanism operates to prevent the intestinal microflora continuously trying to invade. In addition to the intestinal microflora, it is considered that the intestinal mucosa is stimulated by viruses, toxins present in foods and so on. Although it is considered that the intestinal mucosa having such a large area should carry some sensors receiving stimulation and reactors reacting when the sensors receive stimuli, it is scarcely known what kinds of sensors operate therein. For example, it has been clarified that a lactoferrin receptor exists In the intestinal mucosa, However, it has never been known how lactoferrin reacts after binding to the receptor.

Enzymatic modification of sterols using sterol-specific lipase Inventor(s): Basheer, Sobhi; (Sachnin, IL), Plat, Dorit; (Adi, IL) Correspondence: Banner & Witcoff; 1001 G Street N W; Suite 1100; Washington; DC; 20001; US Patent Application Number: 20040105931 Date filed: June 5, 2003 Abstract: The invention relates to a process for the selective alcoholysis of a free sterol, by contacting said free sterol with a fat-based product, optionally with the addition of carboxylic fatty acid(s) and/or ester derivative(s) thereof that are not derived from said fat-based product, in the presence of an immobilized lipase complex which may optionally be surfactant-coated, which complex possesses a high level of sterol-specific alcoholytic and/or esterfication activity and minimal acidolytic and transesterification activities. The fat-based product is a nutritional product or food, particularly butterfat, or a cosmetic or cosmetic or cosmetic-related product. The process may be used for preparing substantially cholesterol-free fat-based products, particularly products containing butterfat, by selectively esterfying any free cholesterol contained therein by the immobilized, preferably surfactant coated lipase. The invention also relates to a process for the in situ enrichment of a fat-based product with esterified phytosterol ester(s). In this process, the esterification of the phytosterol is simultaneously accompanied by esterification of any free cholesterol present in said fat-based product. Excerpt(s): The present invention is concerned with the use of lipases for the selective alcoholysis and/or esterification of sterols. More specifically, the invention relates to the use of lipases for the selective alcoholysis and/or esterification of free cholesterol in foods, particularly in butterfat. The present invention further relates to a process for in situ enriching a fat-based product with esterified phytosterol ester(s) and simultaneously depleting the free cholesterol content of said fat-based product. Sterols
194
Lipase
are alcohols containing a steroid nucleus linked to an 8 to 10-carbon side-chain and a hydroxy group. Such compounds have a wide distribution in the plant and animal kingdoms. The most prevalent plant sterol is ergosterol, while the animal sterol of greatest significance is cholesterol. In recent years it has been increasingly recognized that certain lipid components present in food, including cholesterol, constitute significant risk factors in the pathogenesis of atherosclerotic disease. As a result of research in this field, there have been many attempts to develop methods for modifying the composition of many widely consumed food products, such that the levels of potentially harmful lipid and lipid-like substances are reduced. Of particular prominence in this field are those studies directed at reducing the cholesterol content of food products. In this regard, there is a general interest in developing methods of modifying important dietary fats, such as butterfat, for use in the preparation of low- or zero-cholesterol containing foodstuffs such as butter and ice cream.

Enzymes cooated with ionic liquid Inventor(s): Kim, Mahn-Joo; (Pohang-city, KR), Lee, Jae Kwan; (Suwon-city, KR) Correspondence: Baker & Botts; 30 Rockefeller Plaza; New York; NY; 10112 Patent Application Number: 20040087462 Date filed: September 10, 2003 Abstract: Disclosed is an ionic liquid-coated enzyme, wherein the ionic liquid is an organic salt which presents as a liquid phase at a temperature of about 150.degree. C. or below. The ionic liquid-coated enzyme according to the present invention remarkbly improves enzyme functions, such as enantioselectivity and stability, when the enzyme which may be lipase is coated with an ionic liquid. Further, even in the case of when the ionic liquid-coated enzyme is reused, the enantiomeric excess, enantioselectivity, and activity are not degenerated. The coated enzyme is usable as a catalyst for providing a chiral intermediate required in the synthesis of chiral pesticides, medicines, natural chemicals, and so on. Excerpt(s): The present Invention relates to an enzyme coated with an Ionic liquid and more particularly, to the preparation and use of an enzyme coated with an ionic liquid, which shows better enantioselectivity than its uncoated counterpart and can be repeatedly reused with no significant loss in catalytic activities. Enzymatic kinetic resolution of racemic substrates using hydrolytic enzymes provides a useful methodology for the preparation of optically active compounds. Among the hydrolytic enzymes, lipases (lipid-hydrolyzing enzymes) are of great use since they show broad substrate specificity. Lipases are particularly useful in the resolution of racemic alcohols and their esters In organic solvents. However, they often exhibit unsatisfactory enantioselectivity, resulting in a poor resolution. Accordingly, It is highly important to develop new methods for enhancing the lipase enantioselectivity. Various techniques have been so far developed for solving the enantioselectivity problem, A representative approach is the coating of enzyme with a lipid (Okahata, Y.; Hatano, A.; Ijiro, K Tetrahedron: Asymmetry 1995, 6, 1311) or a surfactant (Huang, S. Y.; Chang, H. L; Goto, M. Enzyme Microb. Technol., 1998, 22, 552). However, these methods are rather complicated to follow and cause loss in enzyme activities.

Feline pancreatic lipase composition and method of preparing and using such composition Inventor(s): Steiner, Jorg M.; (College Station, TX), Williams, David A.; (College Station, TX) Correspondence: Bracewell & Patterson, L.L.P.; Attention: J. Wendy Davis, PH.D.; P.O. Box 61389; Houston; TX; 77208-1389; US Patent Application Number: 20030207333 Date filed: May 2, 2003 Abstract: A novel form of lipase, namely feline pancreatic lipase (also termed feline classical pancreatic lipase) has an N-terminal amino acid sequence as shown in SEQ ID NO. 1. A method of purifying this lipase includes collecting pancreatic tissue from cats, delipidating the pancreatic tissue to produce a delipidated pancreatic extract, extracting pancreatic lipase from the delipidated pancreatic extract, and eluting the extracted

Lipase
pancreatic lipase through various columns. This lipase can be used for measuring pancreatic lipase immunoreactivity in serum thereby diagnosing pancreatitis in cats. To do so, antiserum against feline pancreatic lipase is prepared, and immunoassays are then performed in serum samples using this antiserum. In the event that increased concentration of pancreatic lipase immunoreactivity above the control range is detected in the serum, the cat might have pancreatitis. Excerpt(s): This nonprovisional application claims priority of U.S. Provisional Patent Application Serial No. 60/377,522, filed on May 3, 2002. The present invention relates generally to the field of biology and medicine. More particularly, the present invention relates to feline pancreatic lipase compositions, methods for preparing such compositions, and methods for employing such compositions to detect the concentration of pancreatic lipase in cat serum for diagnosis and management of pancreatitis. Lipases are water-soluble enzymes that hydrolyze water-insoluble substrates into more polar lipolysis products (Petersen and Drabl.o slashed.s, 1994). In 1856 Claude Bernard identified the first lipase (Petersen and Drabl.o slashed.s, 1994). Since then a plethora of lipases has been identified in microorganisms, plants, and animals (Lin et al., 1986; Jaeger et al., 1994; Petersen and Drabl.o slashed.s, 1994; Mukherjee and Hills, 1994; Lawson et al., 1994). Lipases share a common triad of amino acids (serine, aspartic or glutamic acid, and histidine) in the active site, which is also shared with serine proteases (Svendsen, 1994). Another common feature of almost all lipases are glycosylation site motifs (Antonian, 1988). Many lipases have been shown to be related phylogenetically. The pancreatic lipase gene family is a large gene family with 9 subfamilies (Petersen and Drabl.o slashed.s, 1994; Carrire et al., 1997; Carrire et al., 1998; Hirata et al., 1999). In addition there are other groups of phylogenetically related lipases, and yet other lipases that do not belong to a defined gene family (Anderson and Sando, 1991).

Isolated human lipase proteins, nucleic acid molecules encoding human lipase proteins, and uses thereof Inventor(s): Beasley, Ellen M.; (Darnestown, MD), Di Francesco, Valentina; (Rockville, MD), Yan, Chunhua; (Boyds, MD) Correspondence: Celera Genomics CORP.; Attn: Wayne Montgomery, Vice Pres, Intel Property; 45 West Gude Drive; C2-4#20; Rockville; MD; 20850; US Patent Application Number: 20040121441 Date filed: September 2, 2003 Abstract: The present invention provides amino acid sequences of peptides that are encoded by genes within the human genome, the lipase peptides of the present invention. The present invention specifically provides isolated peptide and nucleic acid molecules, methods of identifying orthologs and paralogs of the lipase peptides, and methods of identifying modulators of the lipase peptides. Excerpt(s): The present invention is in the field of lipase proteins that are related to the lysosomal acid lipase subfamily, recombinant DNA molecules, and protein production. The present invention specifically provides novel peptides and proteins that effect protein phosphorylation and nucleic acid molecules encoding such peptide and protein molecules, all of which are useful in the development of human therapeutics and diagnostic compositions and methods. The lipases comprise a family of enzymes with the capacity to catalyze hydrolysis of compounds including phospholipids, mono-, di-,
Patents 197
and triglycerides, and acyl-coa thioesters. Lipases play important roles in lipid digestion and metabolism. Different lipases are distinguished by their substrate specificity, tissue distribution and subcellular localization. Lipases have an important role in digestion. Triglycerides make up the predominant type of lipid in the human diet. Prior to absorption in the small intestine, triglycerides are broken down to monoglycerides and free fatty acids to allow solubilization and emulsification before micelle formation in conjunction with bile acids and phospholipids secreted by the liver. Secreted lipases that act within the lumen include lingual, gastric and pancreatic lipases, each having the ability to act under appropriate pH conditions. Modulating the activity of these enzymes has the potential to alter the processing and absorption of dietary fats. This may be important in the treatment of obesity or malabsorption syndromes such as those that occur in the presence of pancreatic insufficiency.

Schroder; (Ballerup, DK), Munk, Signe; (Kobenhavn K, DK), Patkar, Shamkant Anant; (Lyngby, DK), Svendsen, Allan; (Horsholm, DK), Vind, Jesper; (Vaerlose, DK) Correspondence: Novozymes North America, INC.; 500 Fifth Avenue; Suite 1600; New York; NY; 10110; US Patent Application Number: 20040053360 Date filed: July 3, 2003 Abstract: Attaching a peptide extension to the C-terminal amino acid of a lipase reduces the tendency to form odor. This may lead to lipase variants with a reduced odor generation when washing textile soiled with fat which includes relatively short-chain fatty acyl groups (e.g. up to C8) such as dairy stains containing butter fat or tropical oils such as coconut oil or palm kernel oil. Excerpt(s): The present invention relates to lipase variants with reduced potential for odor generation and to a method of preparing them. It particularly relates to variants suited for use in detergent compositions, more particularly variants of the Thermomyces lanuginosus lipase showing a first-wash effect and a reduced tendency to form odors when washing cloth soiled with milk fat. Lipases are useful, e.g., as detergent enzymes to remove lipid or fatty stains from clothes and other textiles, as additives to dough for bread and other baked products. Thus, a lipase derived from Thermomyces lanuginosus (synonym Humicola lanuginosa, EP 258 068 and EP 305 216) is sold for detergent use under the tradename Lipolase.RTM. (product of Novo Nordisk A/S). WO 0060063 describes variants of the T. lanuginosus lipase with a particularly good first-wash performance in a detergent solution. WO 9704079, WO 9707202 and WO 0032758 also disclose variants of the T. lanuginosus lipase. In some applications, it is of interest to minimize the formation of odor-generating short-chain fatty acids. Thus, it is known that laundry detergents with lipases may sometimes leave residual odors attached to cloth soiled with milk (EP 430315).

Accordingly, the invention provides a method of generating genetic diversity into lipolytic enzymes by family shuffling of two or more homologous genes which encode lipolytic enzymes. The DNA shuffling technique is used to create a library of shuffled genes, and this is expressed in a suitable expression system and the expressed proteins are screened for lipolytic enzyme activity. The expressed proteins may further be screened to identify lipolytic enzymes with improved properties. The invention also provides a polynucleotide comprising a nucleotide sequence encoding a lipolytic enzyme and a lipolytic enzyme (a polypeptide with lipolytic enzyme activity). Excerpt(s): The present invention relates to a method of generating diversity into lipolytic enzymes by the use of the so-called family shuffling of homologous genes. The invention also relates to polynucleotides for use in the method, and to lipolytic enzymes encoded by the polynucleotides. The lipase of Thermomyces lanuginosus (also known as Humicola lanuginosa) is known to be useful for various industrial purposes such as detergents and baking (EP 258068, WO 9404035). Its amino acid and DNA sequences are shown in U.S. Pat. No. 5,869,438. The prior art describes the modification of the amino acid sequence of the T. lanuginosus lipase to create variants with the aim of modifying the enzyme properties. Thus, U.S. Pat.

Method for preparing chiral amines Inventor(s): Ahn, Yangsoo; (Seoul, KR), Choi, Yoon Kyung; (Kyungju-city, KR), Kim, Mahn-Joo; (Pohang-city, KR), Kim, Mi Jung; (Bucheon-city, KR) Correspondence: Baker & Botts; 30 Rockefeller Plaza; New York; NY; 10112 Patent Application Number: 20040077864 Date filed: August 5, 2003 Abstract: Disclosed is a method of preparing chiral amine. The method includes reacting ketoxime, palladium, lipase, acyl-donating compound, and tertiary amine to prepare amide, and amide is hydrolyzed. Excerpt(s): The present invention relates to a method of preparing chiral amines, and more preferably, to a method of preparing chiral amines by simple procedures using starting materials which are easy to handle. The procedures for preparing chiral amines are classified into two categories: chemical procedures using metal catalysts and biochemical procedures using an enzyme catalyst. The chemical procedure and the biochemical procedures have complementary advantages and shortcomings. Thus, the combination of the two catalysts has been attempted the preparation of chiral amines. Till now, only one method reported by a German group (Reetz, M. T; Schimossek, K. Chimia, 1996, 50. 668) utilized the enzyme-metal combination for preparing chiral amines. In this method, a chiral amine was prepared as optically pure amide by dynamic kinetic resolution from the mixture of racemic 1-phenylethylamine as a substrate, palladium as a racemization catalyst, and lipase as a selective acylation catalyst. The optically pure amide is formed by selective acylating the desired enantiomer with an acylating agent in the presence of lipase while the other enantiomer is simultaneously racemized in situ by the action of the palladium catalyst. The reaction was performed at a temperature of 50 to 55.degree. C. for 9 days, and the conversion was 75 to 77%. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Method for preparing flour doughs and products made from such doughs using glycerol oxidase Inventor(s): Madrid, Susan Mampusti; (Vedboek, DK), Poulsen, Charlotte Horsmans; (Bradbrand, DK), Rasmussen, Preben; (Kirke Hyllinge, DK), Soe, Jorn Borch; (Mundelstrup, DK), Zargahi, Masoud R.; (Arhus C., DK) Correspondence: Frommer Lawrence & Haug; 745 Fifth Avenue- 10th FL.; New York; NY; 10151; US Patent Application Number: 20040071853 Date filed: June 16, 2003 Abstract: Method of improving the rheological properties of a flour dough and the quality of bread, alimentary paste products, noodles and cakes wherein glycerol oxidase or a combination of glycerol oxidase and a lipase is added to the dough and dough improving compositions comprising these enzymes. The strength of (B/C ratio) and the gluten index of the dough was improved and in the resulting products the improvements were higher specific volume, increased crumb pore homogeneity and reduced average crumb pore diameter. Excerpt(s): The present invention relates to the field of food manufacturing, in particular to the preparation of improved bakery products and other farinaceous food products. Specifically, the invention concerns the use of glycerol oxidase as a dough strengthening agent and improvement of the quality of baked and dried products made from such improved doughs. There is also provided a method of improving the properties of doughs and baked product by combined use of glycerol oxidase and a lipase. The "strength" or "weakness" of doughs is an important aspect of making farinaceous finished products from doughs, including baking. The "strength" or "weakness" of a dough is primarily determined by its content of protein and in particular the content and the quality of the gluten protein is an important factor in that respect. Flours with a low protein content is generally characterized as "weak". Thus, the cohesive, extensible, rubbery mass which is formed by mixing water and weak flour will usually be highly extensible when subjected to stress, but it will not return to its original dimensions when the stress is removed. Flours with a high protein content are generally characterized as "strong" flours and the mass formed by mixing such a flour and water will be less extensible than the mass formed from a weak flour, and stress which is applied during mixing will be restored without breakdown to a greater extent than is the case with a dough mass formed from a weak flour. Strong flour is generally preferred in most baking contexts because of the superior rheological and handling properties of the dough and the superior form and texture qualities of the finished baked or dried products made from the strong flour dough.

Method for the production of (1S, 4R)-(-)-4-hydroxy cyclopent-2-enyl esters Inventor(s): Wisdom, Richard; (Hattersheim, DE) Correspondence: Clariant Corporation; Industrial Property Department; 4000 Monroe Road; Charlotte; NC; 28205; US Patent Application Number: 20040126855 Date filed: December 12, 2003
Patents 201
Abstract: Process for the preparation of (1S, 4R)-4-hydroxy cyclopent-2-enyl esters comprising the steps of:a) reacting a cis-cyclopent-1-ene-3,5-diol, or racemic or a partially resolved4-hydroxy cyclopent-2-enyl ester, with a suitable ester donor in the presence a lipase from Alcaligenes sp. andb) recovering and purifying the produced (1S, 4R)-4-hydroxy cyclopent-2-enyl ester.The reaction is preferably carried out at a temperature in the range from 10.degree. C. to room temperature. Excerpt(s): The instant application refers to a new method for the production of (1S, 4R)(-)-4-hydroxy cyclopent-2-enyl esters, preferably (1S, 4R)-(-)-4-hydroxy cyclopent-2-enyl acetate and -proprionate and its derivatives. (1S, 4R)-(-)-4-Hydroxy cyclopent-2-enyl acetate has been identified as a very useful synthon in the preparation of prostaglandins and other cyclopentanoid products (M. Nara et al, Tetrahedron 36 (1980) 3161; M. Harre et al, Angew. Chemie 94 (1982) 496; Johnson C R. et al., J. Am. Chem. Soc, 115, 1101411015, (1993)). As a result, numerous approaches have been described over the years to prepare this material. Many of these approaches utilise the selective ability of enzymes and, in particular esterases and lipases, to recognise and preferentially produce the preferred enantiomer. Two related enzymatic routes to the required compound have been described. Firstly it is possible to utilise an enzyme to selectively hydrolyse cis-3,5diacetoxy cyclopent-1-ene, which may readily be prepared by the method described by Deardorff (Deardorff et al., Tetrahedron Letters 26, (46), pp 5615-5618 (1985)). Laumen et al. (Laumen et al., Tetrahedron Letters, 25 (51), pp 5875-5878, (1984)) screened a number of enzymes to identify their selectivity. U.S. Pat. No. 4,618,690 describes an example with Pig liver esterase in which a yield of the required enantiomer of 86% on starting cis-3,5-diacetoxy cyclopent-1-ene is obtained, however the ee is only 66%. Although it was possible to increase ee to 86% on one crystalisation and thereafter probably higher on subsequent recrystalisations, this would significantly reduce yields. It is known that commercial preparations of pig liver esterases are a mixture of variants, and it may be that use of a single cloned and expressed variant may give higher selectivity. A recent patent, U.S. Pat. No. 6,448,051 identifies a range of organisms of Trichosporon sp which show high selectivity in their hydrolysis of cis-3,5-diacetoxy cyclopent-1-ene and which produce the required enantiomer of 4-hydroxy cyclopent-2-enyl acetate. Yields of over 80% are described, however in the best case this process uses whole cells at a ratio of 1 part cell biomass to 1 part substrate and the concentrations of product in the biotransformation are less than 1%. Thus as well as the problems of product extraction from aqueous biological solutions, which are known to sometimes cause emulsion problems, the volumetric yields are low. It would be unlikely that the process as described would be suitable for large scale production in a chemical facility. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Method of purifying crude xanthophylls Inventor(s): Hukami, Tadashi; (Toyama, JP), Ikai, Hisato; (Hisato, JP), Ikushima, Heiji; (Toyama, JP), Nagao, Toshihiro; (Osaka, JP), Shimada, Yuji; (Osaka, JP), Sugihara, Akio; (Hyogo, JP), Tominaga, Yoshio; (Osaka, JP) Correspondence: Flynn Thiel; Boutell & Tanis; 2026 Rambling Road; Kalamazoo; MI; 49008-1699; US Patent Application Number: 20040115758 Date filed: January 15, 2004 Abstract: There is disclosed herein a process for purifying a crude xanthophyll which is characterized by acting a lipase on the crude xanthophyll, which is obtained by
202
Lipase
extracting algae with a solvent, in the present of water under an acidic condition without adjusting the pH whereupon the contaminating neutral lipids (mono-, di- and triglycerides) are selectively hydrolyzed, subjecting the lipase-treated liquor to oil/water separation and removing free fatty acids from the oil layer fractioned thereby elevating the content of xanthophyll. Excerpt(s): The present invention relates to a process for purifying crude xanthophylls, and more particularly it relates to a process for purifying crude xanthophylls, which makes it possible to provide high quality of xanthophylls so that they may be widely used in the fields of a food, a medicine, quasi-drugs, a cosmetic, a cultivation and so on, by hydrolyzing fatty esters of glycerin, principal contaminant derived from the raw material for preparing xanthophylls, with a lypase and removing the resultant hydrolyzate thereby increasing the content of xanthophyll components efficiently and further removing particular odor derived from the raw material. The xanthophylls, one kind of carotenoids are compounds containing one or more hydroxyl groups in the cyclic structure moiety of the molecular skeleton and are present in two or three forms of xanthophyll (free form), mono- and di-esters thereof depending on the number of hydroxyl group. Synthetic xanthophylls or natural ones derived from animal and vegetable are known. As astaxanthin, astaxanthin monoester and astaxanthin diester (hereinafter, referred to as "astaxanthins" collectively) being one of the representative xanthophylls, both the synthetic ones and natural ones derived from animal and vegetable have been commercially sold. Specifically, they may be obtained from an animal such as a crab, a shrimp, a krill and the like by extraction, and they may also be obtained by squeezing oil from algae, for example green algae such as Haematococcus, chlorella, Scenedesmus and the like; from yeasts such as Falfa rhodozyma and the like; or from microorganisms such as bacteria, alternatively by extraction from them through organic solvents such as acetone, ethylacetate, dichloroethane and the like or otherwise an edible oil. The astaxanthins have been expected for utilization as a natural coloring agent, an antioxidant, a health food, a cosmetic and a medicine because they convert into provitamin A after taken in the body and because they have remarkable antioxidant action (Eiji Yamashita; "Food and Development" vol. 27, No. 3, p 38-40 (1992)). Various processes are reported for extracting xanthophylls from a vegetable, green algae, bacteria, cruschimata, etc. If specifically astaxanthins are explained taking as the example, the followings are: a process for extracting astaxanthins with an alkyl ester of a fatty acid (Japanese Patent Application Laid-Open No. Sho 58-88358), a process for extracting them with trichloromonofluoromethane (Japanese Patent Application LaidOpen No. Hei 2-255711), a process wherein a shell of a shrimp or a crab is dipped in hydrochloric acid to remove calcium present in the shell and then the resultant shell is dipped in a sodium hydroxide solution for a neutral treatment and removal of the protein present in the shell and subsequently the resultant shell is dipped in a solvent comprising 80% of alcohol for brewing and 20% of water at a temperature of 78.+.5.degree. C. to separate and extract astaxanthin from the solvent (Japanese Patent Application Laid-Open No. Hei 9-301950), etc. Also, in case of yeasts, there is reported a process wherein the cell walls of yeast after cultivation are broken physically or by acting a cell wall decomposing enzyme thereon and then astaxanthin is extracted from the ruptured cell walls with a mixed solution of hexane and ethanol (Japanese Patent Application Laid-Open No. Hei 7-41687), or a process wherein the cell walls of Falfa rhodozyma yeast are ruptured by heat-treatment at a temperature of 40.degree. C. or more (Japanese Patent Application Laid-Open No. Hei 8-214870). Also, as processes for extracting astaxanthins from algae, for example a process wherein Haematococcus is subjected to a physical rupturing treatment and thereafter astaxanthins are extracted (WO 89/06910), a process wherein the cell walls are ruptured by the application of
Patents 203
turbulent flow under high pressure and the ruptured cell walls are dried and astaxanthins are extracted with an organic solvent (Japanese Patent Application LaidOpen No. Hei 9-111139) or a process wherein algae containing astaxanthins for example Haematococcus is treated with acetone heated (to 40.degree. C.-boiling point) and then treated with a cell wall decomposing enzyme which comprises the respective components of.beta.-1,3-glucanase,.beta.-1,4-glucanase and.beta.-glucuronidase to extract astaxanthins (Japanese Patent Application Laid-Open No. Hei 11-56346) is reported. In addition, a process for extracting astaxanthins from krill crust in a supercritical state (carbon dioxide) (Japanese Patent Application Laid-Open No. Hei 6200179) or a process for extracting them from bacteria is reported.

Methods for processing crustacean material Inventor(s): Nielsen, Per Munk; (Hillerod, DK) Correspondence: Novozymes North America, INC.; 500 Fifth Avenue; Suite 1600; New York; NY; 10110; US Patent Application Number: 20030185939 Date filed: March 11, 2003 Abstract: The inventor has found that enzymatic treatment of crustaceans with lipolytic enzymes promotes the extraction of coloured pigment. Accordingly, the invention relates to a method for recovering coloured pigment, e.g. astaxanthin, and/or chitin or chitosan and/or lysolecithins from crustaceans. Lipolytic enzyme(s) may e.g. be lipase or phospholipase. The lipolytic enzyme treated crustacean material may be subjected to additional process steps, including treatment with non-lipolytic enzymes such as e.g. protease. The process of the invention provides several suitable products and several uses of such products. Furthermore, the invention also relates to the cosmetic and consumable products (feed and food (including beverages) products and additives produced therefrom. Excerpt(s): The present invention relates to methods for enzymatically processing crustaceans in order to provide useful products therefrom. The usage of carotenoid pigments such as astaxanthin is increasing in the field of food and feed additives as a colorant and/or as an anti-oxidant, in particular for aquacultered fish. Aquatic animals, like terrestrial animals, generally cannot synthesize astaxanthin or other carotenoids but several of these animals, including crustaceans, accumulate astaxanthin present in their diet. Crustaceans have the capability of converting carotenes to astaxanthin. Salmonid fish and red sea bream fish accumulate dietary astaxanthin but these fish cannot convert other carotenes to astaxanthin. Thus, the astaxanthin present in salmonid fish must be derived directly from dietary source. Currently synthetic astaxanthin is employed as feed additive for coloration of farmed fish for providing its desired characteristic reddish colour. However, consumer concerns have resulted in an increased demand for providing natural astaxanthin to substitute the synthetically produced astaxanthin. This should also be seen in the light of the current general preference for natural products. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Methods for using lipases in baking Inventor(s): Golightly, Elizabeth J.; (Davis, CA), Rey, Michael W.; (Davis, CA), Spendler, Tina; (Herlev, DK) Correspondence: Novozymes Biotech, INC.; 1445 Drew Ave; Davis; CA; 95616; US Patent Application Number: 20030180418 Date filed: May 5, 2003 Abstract: The present invention relates to methods for preparing a dough, comprising incorporating into the dough a composition comprising an effective amount of a lipase which improves one or more properties of the dough or a baked product obtained from the dough. The present invention also relates to methods for preparing a baked product. The present invention also relates to compositions comprising an effective amount of such a lipase for improving one or more properties of a dough and/or a baked product obtained from the dough. The present invention further relates to doughs or baked products and to pre-mixes for a dough. Excerpt(s): The present invention relates to methods for preparing a dough and/or baked product with a lipase. The strength of a dough is an important aspect of baking for both small-scale and large-scale applications. A strong dough has a greater tolerance of mixing time, proofing time, and mechanical vibrations during dough transport, whereas a weak dough is less tolerant to these treatments. A strong dough with superior rheological and handling properties results from flour containing a strong gluten network. Flour with a low protein content or a poor gluten quality results in a weak dough. Dough "conditioners" are well known in the baking industry. The addition of conditioners to bread dough has resulted in improved machinability of the dough and improved texture, volume, flavor, and freshness (anti-staling) of the bread. Nonspecific oxidants, such as iodates, peroxides, ascorbic acid, potassium bromate and azodicarbonamide have a gluten strengthening effect. It has been suggested that these conditioners induce the formation of interprotein bonds which strengthen the gluten, and thereby the dough. However, the use of several of the currently available chemical oxidizing agents has been met with consumer resistance or is not permitted by regulatory agencies.

Modulation of endothelial lipase expression Inventor(s): Dobie, Kenneth W.; (Del Mar, CA) Correspondence: Marshall, Gerstein & Borun; 6300 Sears Tower; 233 South Wacker Drive; Chicago; IL; 60606-6357; US Patent Application Number: 20040115653 Date filed: December 12, 2002 Abstract: Compounds, compositions and methods are provided for modulating the expression of endothelial lipase. The compositions comprise oligonucleotides, targeted to nucleic acid encoding endothelial lipase. Methods of using these compounds for modulation of endothelial lipase expression and for diagnosis and treatment of disease associated with expression of endothelial lipase are provided. Excerpt(s): The present invention provides compositions and methods for modulating the expression of endothelial lipase. In particular, this invention relates to compounds,

particularly oligonucleotide compounds, which, in preferred embodiments, hybridize with nucleic acid molecules encoding endothelial lipase. Such compounds are shown herein to modulate the expression of endothelial lipase. Atherosclerosis is the major causative factor of heart disease and stroke, and the leading cause of death in Western countries is cardiovascular disease. Dyslipidaemia is a primary contributor to atherosclerosis. Because triglycerides are insoluble in the bloodstream, they are packaged for plasma transport into micelle-like lipoprotein particles composed of protein and phospholipid shells surrounding a non-polar core of acylglycerols, free cholesterol, and cholesterol esters. Lipoproteins have been classified into five broad categories on the basis of their functional and physical properties: chylomicrons (which transport dietary lipids from intestine to tissues); very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL) and low density lipoproteins (LDL), (all of which transport triacylglycerols and cholesterol from the liver to tissues); and high density lipoproteins (HDL) (which transport endogenous cholesterol from tissues to the liver, as well as mediating selective cholesteryl ester delivery to steroidogenic tissues). All of these particles undergo continuous metabolic processing and have somewhat variable properties and compositions. Plasma concentrations of LDL and HDL are directly and inversely related, respectively, to the risk of atherosclerotic cardiovascular disease (Krieger, Proc. Natl. Acad. Sci U.S.A. 1998, 95, 4077-4080). HDL protect the arterial wall from the development of atherosclerosis by promoting efflux of excess cholesterol from cells in the arterial wall and returning it to the liver for excretion into the bile, as well as by protecting LDL from oxidation, thereby reducing the inflammatory response of epithelial cells, inhibiting the coagulation pathway, and promoting the availability of nitric oxide. The metabolism of HDL is influenced by several members of the triacylglycerol (TG) lipase family of proteins, which hydrolyze triglycerides, phospholipids and cholesteryl esters, generating fatty acids to facilitate intestinal absorption, energy production or storage. Of the TG lipases, lipoprotein lipase (LPL) influences the metabolism of HDL cholesterol by hydrolyzing triglycerides in triglyceride-rich lipoproteins, resulting in the transfer of lipids and apolipoproteins to HDL and is responsible for hydrolyzing chylomicron and VLDL in muscle and adipose tissues. Hepatic lipase (HL) hydrolyzes HDL triglyceride and phospholipids, generating smaller, lipid-depleted HDL particles, and plays a role in the uptake of HDL cholesterol (Jin et al., Trends Endocrinol. Metab., 2002, 13, 174-178; Wong and Schotz, J. Lipid Res., 2002, 43, 993-999). Endothelial lipase (also known as EDL, EL, LIPG, endothelial-derived lipase and endothelial cell-derived lipase) was identified using differential display to isolate mRNAs which were differentially regulated in response to oxidized-LDL (Jaye et al., Nat. Genet., 1999, 21, 424-428). Independently, the human endothelial lipase gene was identified in human umbilical vein endothelial cells (HUVECs) undergoing tube formation in a model of vascular formation (Hirata et al., J. Biol. Chem., 1999, 274, 1417014175). Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Nutritional supplement containing alpha-glucosidase and alpha-amylase inhibitors Inventor(s): Murray, Mary A.; (Irvine, CA), Roh-Schmidt, Haeri; (Ada, MI), Roufs, James B.; (Santa Monica, CA) Correspondence: Brinks Hofer Gilson & Lione; Post Office Box 10395; Chicago; IL; 60610; US Patent Application Number: 20040091554 Date filed: November 7, 2002 Abstract: A nutritional supplement composition contains inhibitors of alpha-glucosidase and alpha-amylase substantially in the absence of lipase inhibitors. The composition can include touchi extract and phaseolamin as the alpha-glucosidase and alpha-amylase inhibitor, respectively. A method of limiting the absorption of carbohydrates contained in a foodstuff includes administering the nutritional supplement composition prior to consumption of the carbohydrates, and a method of promoting weight loss in an individual includes administering the nutritional supplement composition to the individual over a period of days. Excerpt(s): The present invention relates to nutritional supplement compositions containing alpha-glucosidase and alpha-amylase inhibitors. More specifically, the invention relates to nutritional supplement compositions that include effective amounts of alpha-glucosidase and alpha-amylase inhibitors substantially in the absence of lipase inhibitor. The present invention also relates to methods of limiting the absorption of carbohydrates contained in a foodstuff, and to methods of promoting weight loss in an

individual. Carbohydrates are nutritional compounds that are present in a wide array of foodstuffs. They are a group of numerous different compounds that occur in a variety of sizes and configurations. All carbohydrates are composed of one or more sugar units linked together through glycosidic bonds. Complex carbohydrates, such as starch, are relatively large molecules consisting of numerous repeating units formed into a multibranched chain structure. Monosaccharides and disaccharides, on the other hand, are simple carbohydrates that comprise single and double sugar units, respectively. The human body digests complex carbohydrates by breaking them into relatively simple units, monosaccharides, and then absorbing these units into a tissue, such as the intestine. A variety of digestive enzymes work in a stepwise manner to break the complex carbohydrates into the absorbable units. In an initial step, salivary and pancreatic enzymes known as amylases break large carbohydrates into smaller units of oligo- and disaccharides. In one of the final steps of carbohydrate digestion, alphaglucosidase enzymes in the brush border of the small intestine break the disaccharides maltose and sucrose into their respective monosaccharide units, which can then be absorbed by the body.

Excerpt(s): This application is a divisional of U.S. patent application Ser. No. 09/912,957, filed Jul. 25, 2001, currently pending. The present invention relates to pharmaceutical combinations, compositions and methods for treating obesity. Bile acids are synthesized in the liver and enter the bile as glycine and taurine conjugates. They are released in salt form in bile during digestion and act as detergents to solubilize and consequently aid in digestion of dietary fats. Following digestion, bile acid salts are mostly reabsorbed in the ileum, complexed with proteins, and returned to the liver through the hepatic portal vein. The small amount of bile acid salts which are not reabsorbed by active transport are excreted via the distal ileum and large intestine as a portion of fecal material. Reducing reabsorption of bile acids within the intestinal tract can lower levels of bile acid circulating in the enterohepatic system thereby potentially reducing emulsification in the upper intestinal tract of dietary fat and reducing intestinal absorption of fat soluble drugs. One method of reducing the amount of bile acids that are reabsorbed, is oral administration of compounds that sequester the bile acids within the intestinal tract and cannot themselves be absorbed.

The process is of particular application for the production of (-)-menthol. Excerpt(s): THIS invention relates to a process for producing (-)-menthol and similar compounds. Menthol has been the subject of much research in the flavour industry. The molecule of menthol has three asymmetric carbon atoms, and hence, a total of eight optically active isomers are possible. The eight isomers are (-)-menthol, (+)-menthol, (-)isomenthol, (+)-isomenthol, (-)-neomenthol, (+)-neomenthol, (-)-neoisomenthol and (+)neoisomenthol. Of all of these isomers only (-)-menthol has a strong refreshing character and is widely used in perfumes and medicines. Thus, the isolation of (-)-menthol from the other isomers is industrially important. As previously discussed, reacemic menthol contains four stereoisomeric pairs of menthols. The isolation of (-)-menthol from this isomeric mixture can be performed chemically via crystallisation, freeze-drying or distillation. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

ESQ.; International Flavors & Fragrances INC.; 521 West 57th Street; New York; NY; 10019; US Patent Application Number: 20040001819 Date filed: April 22, 2003 Abstract: The present invention provides kPGE and derivative polypeptides which are capable of being produced by genetic recombination and used to produce EMCs. This invention further provides nucleic acid sequences encoding kPGE and derivative polypeptides which can be used to create recombinant host cells that express kPGE and derivative polypeptides. A further subject of the present of invention is a fusion polypeptide called polyHis-enterokinase which increases expression of esterases and lipases when fused to the N-terminal of the esterase or lipase. This invention also provides a method for treating animals with an esterase or lipase deficiency by administering rkPGE to the animal in a therapeutically effective amount. Excerpt(s): Throughout this specification, various references are identified by a number in parantheses. The citation to the reference corresponding to the identified number can be found in the section entitled References Cited preceding the claims. The references in that section are hereby incorporated by reference. Esterases (also referred to as lipases) are enzymes that cleave triglycerides (fats or lipids) or esters into carboxylic acids (fatty acids) and mono- and di-glycerides. For an explanation of the slightly different definitions given to lipases and esterases see Siezen, R. J. and van den Berg, (37). A pregastric esterase is an esterolytic or lipolytic enzyme secreted by the oral tissues of mammals. Animal esterases in an unpurified form called rennet have been used in the production of dairy food products and, in particular, the production of enzyme modified cheeses or EMCs. (8), (9), (10), (17), (18), (33), (40), and (41). In particular, cheeses like Romano and Provolone have a "peppery" or "piccante flavor due to the fatty acid composition created by the enzyme in the rennet paste. (26), (37). Traditionally EMCs are prepared by esterases obtained from the gullet of slaughtered animals from which a rennet paste or powder is obtained. The rennet is used to treat whey to impart flavor into the cheese product. Kid pregastric estersase (kPGE or kid PGE) in rennet paste is contaminated with proteins which are found in the gullet of the kid and other substances used in the preparation of the rennet. It would be useful to have an uncontaminated kPGE to produce EMC's. Such EMC's could be produced in a manner acceptable to kosher and vegetarian consumers. A recombinant kPGE (rKPGE) could be produced in very pure form free of the other substances found in the present commercial rennet formulations.

The reaction produces lower molecular weight fatty acids and.beta.-mono- and diglycerides. The resultant lipids are absorbed into digestive tract cells with the aid of emulsifying bile acids. The triglycerides are re-synthesized in the endoplasmic reticulum as chylomicrons. See review by Pullinger and Kane, "Lipid Metabolism and Transport," in MOLECULAR BIOLOGY AND BIOTECHNOLOGY, Meyers, ed., VCH Publishers, New York, 1995.

The invention also relates to the construction of a chimeric gene encoding all or a portion of the triacylglycerol lipase, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the triacylglycerol lipase in a transformed host cell. Excerpt(s): This application is a divisional of U.S. application Ser. No. 09/699,652, filed Oct. 30, 2000 which is a continuation of International Application No. PCT/US99/09280, filed Apr. 29, 1999 now expired, which claims the benefit of U.S. Provisional Application No. 60/083,688, filed Apr. 30, 1998 now expired. The entire content of these applications is herein incorporated by reference in their entirety. This invention is in the field of plant molecular biology. More specifically, this invention pertains to nucleic acid fragments encoding triacylglycerol lipases in plants and seeds. True lipases attach triacylglycerols and act at an oil-water interface; they constitute a ubiquitous group of enzymes catalyzing a wide variety of reactions, many with industrial potential. Triacylglycerol lipases catalyze the transformation of triacylglycerol and water into diacylglycerol and a fatty acid anion. Human gastric lipase, rat lingual lipase, and human hepatic lysosomal lipase amino acid sequences are homologous but are unrelated to porcine pancreatic lipase apart from a 6 amino-acid sequence around the essential Ser-152 of porcine pancreatic lipase (Bodmer, M. W. (1987) Biochim Biophys Acta 909:237-244). These enzymes are glycosylated, contain a hydrophobic signal peptide, and belong to a gene family of acid lipases (Ameis, D. et al. (1994) Eur J Biochem 219:905-914). Lysosomal acid lipase (LAL) is a hydrolase essential for the intracellular degradation of cholesteryl esters and triacylglycerols and participates in the mobilization of seed oil during germination. No plant triacylglycerol lipase cDNAs of this class are currently listed in GenBank. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

In a preferred embodiment, this disclosure relates to compositions comprising polymeric foam materials made from high internal phase emulsions, where such foams are useful for sequestering lipophilic materials. Further disclosed are compositions comprising open-celled polymeric foams wherein the compositions are useful for the purpose of sequestering aqueous and/or hydrophilic materials present in the gastrointestinal tract, thereby ameliorating diarrhea. Kits comprising the compositions and methods of using the compositions and kits are also described. Excerpt(s): This application claims priority under Title 35, United States Code.sctn. 119(e) from Provisional Application Serial No. 60/277,058, filed Mar. 19, 2001 and under Title 35, United States Code.sctn. 120 from U.S. patent application Ser. No. 10/083,218, filed Feb. 26, 2002 and U.S. patent application Ser. No. 10/251,376, filed Sep. 20, 2002. The present invention relates to compositions comprising an open-celled polymeric foam wherein the compositions are useful for sequestering lipophilic materials present in the gastrointestinal tract, thereby inhibiting the absorption of such lipophilic materials by the body. The invention further relates to compositions comprising the open-celled polymeric foam wherein the compositions are useful for ameliorating side effects associated with the use of lipase inhibitors. This invention further relates to compositions comprising an open-celled polymeric foam wherein the compositions are useful for the purpose of sequestering aqueous and/or hydrophilic materials present in the gastrointestinal tract, thereby ameliorating diarrhea. This invention additionally relates to kits comprising the compositions and methods of using the compositions and kits. Approximately one third of Americans aged 20 to 74 are considered to be obese, and approximately half of Americans in this age group are considered to be overweight. Obesity is also considered to be a growing problem in other industrialized countries and in developing countries where large numbers of people have become accustomed to Western-influenced high-caloric diets. It has been estimated that obesity contributes to 50% of chronic diseases in Western societies and is responsible for approximately 70% of preventable deaths in the U.S.A. Health care costs associated with obesity are substantial. As a result of these factors, the development of compositions to effect weight-loss is the subject of significant commercial interest.

PRICE: $11.95 plus shipping and handling. ISBN: 019508554X. Summary: This chapter on pancreatic conditions is from a book that offers advice on how to take care of and avoid the whole complex of disturbances categorized as indigestion. The pancreas is a key digestive gland that manufactures digestive enzymes to digest starch (amylase), break down fats (lipase), and digest proteins (trypsinogen and chymotrypsinogen, among others). The pancreas includes the Islets of Langerhans which make the hormones, including insulin (which regulates blood sugar levels and sugar metabolism), glucagon (which raises blood sugar), somatostatin (which turns off the intestinal juices), and vasoactive intestinal polypeptide (which turns off stomach juices, silences the gallbladder, and stimulates the intestines). The author notes that the pancreas is very sensitive to the action of certain drugs, alcohol, caffeine, and trouble in the gallbladder. The pancreas can malfunction as acute pancreatitis or in a slower more insidious form known as chronic pancreatitis. The author reviews the risk factors for pancreatitis, the symptoms of acute and chronic difficulties with the pancreas, the causes of pancreatitis, diagnostic considerations, and treatment for acute pancreatitis. The pancreas has great recuperative properties that can restore it even after a severe attack. The individual who has recovered from pancreatitis need not suffer any chronic disturbance in digestion or metabolism, provided that no further damage is done to the gland again. If repeatedly insulted, however, by alcohol, undiagnosed gallbladder disease, toxic drugs, or uncorrected metabolic diseases, the pancreas can develop serious problems leading to diabetes or malnutrition.

Gender, Genetics, and Obesity Source: Bethesda, MD: National Institute of Diabetes and Digestive and Kidney Diseases, 1992, 60 minutes. Contact: WIN, 1 WIN WAY, Bethesda, MD 20892-3665. Summary: In this lecture, Dr. Greenwood discusses current understanding of the impact of gender and genetics on obesity and describes animal and human studies that offer clues about why it is so difficult to treat obesity. Data strongly suggest that increased incidence and prevalence of obesity in the United States is not caused solely by increased caloric intake. Dr. Greenwood describes the different patterns of obesity that tend to occur in men and in women and evidence from various studies suggesting that fat distribution may be the factor contributing most to the health risk of obesity. The lecture goes on to discuss animal models that suggest the vulnerability to obesity may be the result of aberrant nutrition partitioning, whereby a higher than normal proportion of nutrients are deposited in fatty tissue, leaving other tissues (notably skeletal muscle) relatively deprived. Dr. Greenwood and her colleagues propose that
222
Lipase
overeating is an adaptive response to this process, which they believe may be regulated by lipoprotein lipase, an enzyme manufactured by fat cells. Dr. Greenwood also examines research on weight cycling, a phenomenon in which an individual loses weight, gains it back, loses it again, and so on. Evidence gleaned from studies in both rats and humans suggests that weight cycling may be an independent risk factor for increased morbidity and mortality, and may also be associated with the decreased effectiveness of weight loss methods. However, Dr. Greenwood notes that no long-term studies have been conducted on the effects of weight cycling, and that this is an important area for future research. The lecture concludes with the observation that weight loss advice should address the need for physical fitness and permanent lifestyle change and diet composition over caloric restriction.

CHAPTER 9. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for lipase. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with lipase. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/.
PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee. If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Coffee Break: Tutorials for Biologists18 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.19 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.20 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
18 Adapted 19
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 20 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on lipase can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to lipase. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to lipase. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “lipase”:

Lipase
Laboratory Tests http://www.nlm.nih.gov/medlineplus/laboratorytests.html Liver Diseases http://www.nlm.nih.gov/medlineplus/liverdiseases.html Metabolic Disorders http://www.nlm.nih.gov/medlineplus/metabolicdisorders.html Pancreatic Diseases http://www.nlm.nih.gov/medlineplus/pancreaticdiseases.html Preventing Disease and Staying Healthy http://www.nlm.nih.gov/medlineplus/preventingdiseaseandstayinghealthy.html You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to lipase. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to lipase. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with lipase. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about lipase. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “lipase” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “lipase”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “lipase” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months.

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.21
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

LIPASE DICTIONARY The definitions below are derived from official public sources, including the National Institutes of Health [NIH] and the European Union [EU]. Abdomen: That portion of the body that lies between the thorax and the pelvis. [NIH] Abdominal: Having to do with the abdomen, which is the part of the body between the chest and the hips that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs. [NIH] Abdominal fat: Fat (adipose tissue) that is centrally distributed between the thorax and pelvis and that induces greater health risk. [NIH] Abdominal Pain: Sensation of discomfort, distress, or agony in the abdominal region. [NIH] Aberrant: Wandering or deviating from the usual or normal course. [EU] Acceptor: A substance which, while normally not oxidized by oxygen or reduced by hydrogen, can be oxidized or reduced in presence of a substance which is itself undergoing oxidation or reduction. [NIH] ACE: Angiotensin-coverting enzyme. A drug used to decrease pressure inside blood vessels. [NIH]
Acetone: A colorless liquid used as a solvent and an antiseptic. It is one of the ketone bodies produced during ketoacidosis. [NIH] Acetylcholine: A neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications. [NIH] Acetylcholinesterase: An enzyme that catalyzes the hydrolysis of acetylcholine to choline and acetate. In the CNS, this enzyme plays a role in the function of peripheral neuromuscular junctions. EC 3.1.1.7. [NIH] Acetyltransferases: Enzymes catalyzing the transfer of an acetyl group, usually from acetyl coenzyme A, to another compound. EC 2.3.1. [NIH] Acne: A disorder of the skin marked by inflammation of oil glands and hair glands. [NIH] Actin: Essential component of the cell skeleton. [NIH] Acute renal: A condition in which the kidneys suddenly stop working. In most cases, kidneys can recover from almost complete loss of function. [NIH] Acyl: Chemical signal used by bacteria to communicate. [NIH] Acylation: The addition of an organic acid radical into a molecule. [NIH] Adaptation: 1. The adjustment of an organism to its environment, or the process by which it enhances such fitness. 2. The normal ability of the eye to adjust itself to variations in the intensity of light; the adjustment to such variations. 3. The decline in the frequency of firing of a neuron, particularly of a receptor, under conditions of constant stimulation. 4. In dentistry, (a) the proper fitting of a denture, (b) the degree of proximity and interlocking of restorative material to a tooth preparation, (c) the exact adjustment of bands to teeth. 5. In microbiology, the adjustment of bacterial physiology to a new environment. [EU] Adenosine: A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine
250
Lipase
derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. [NIH] Adenovirus: A group of viruses that cause respiratory tract and eye infections. Adenoviruses used in gene therapy are altered to carry a specific tumor-fighting gene. [NIH] Adipocytes: Fat-storing cells found mostly in the abdominal cavity and subcutaneous tissue. Fat is usually stored in the form of tryglycerides. [NIH] Adipose Tissue: Connective tissue composed of fat cells lodged in the meshes of areolar tissue. [NIH] Adjustment: The dynamic process wherein the thoughts, feelings, behavior, and biophysiological mechanisms of the individual continually change to adjust to the environment.

Abdominal body fat is thought to be associated with a rapid mobilization of fatty acids rather than resulting from other fat depots, although it remains a point of contention. If abdominal fat is indeed more active than other fat depots, it would then provide a mechanism by which we could explain (in part) the increase in blood lipid and glucose levels. The latter have been clearly associated with an increased risk for cardiovascular disease, hypertension, and type 2 diabetes. The gynoid type (pear-shaped) of body fat is usually seen in women.

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
