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 aortic stenosis is indexed in search engines, such as www.google.com or others, a non-systematic 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 aortic stenosis, 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 aortic stenosis, 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 aortic stenosis. 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 aortic stenosis, 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 aortic stenosis. The Editors

CHAPTER 1. STUDIES ON AORTIC STENOSIS Overview In this chapter, we will show you how to locate peer-reviewed references and studies on aortic stenosis.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and aortic stenosis, 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 “aortic stenosis” (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: •
Uremic Cardiomyopathy: Reducing the Cardiac Burden in End-Stage Renal Disease Source: Journal of Critical Illness. 13(10): 613-615, 619-623. October 1998. Contact: Available from Cliggott Publishing Company. 55 Holly Hill Lane, Greenwich, CT 06831-0010. (203) 661-0600. Summary: Left ventricular (LV) hypertrophy and dilatation and systolic dysfunction are common in patients receiving hemodialysis and are associated with significantly decreased survival and increased morbidity. In this article, the authors discuss abnormalities of LV structure and function. They cover the diagnosis of uremic cardiomyopathy, review data on the prevalence and outcomes of LV dysfunction, and explore interventions relevant to the management of these patients. Echocardiography is the standard diagnostic tool for cardiomyopathy in patients with end-stage renal disease

Aortic Stenosis
(ESRD). The use of echocardiography to differentiate diastolic from systolic dysfunction can help guide patient management. With few controlled clinical trials specifically examining cardiomyopathy in uremic patients, management generally follows guidelines from studies in the general population. Aims of therapy are to improve quality of life by controlling symptoms of heart failure, ischemic heart disease, cardiac arrhythmias, and dialysis-associated hypotension; and to correct modifiable risk factors, such as hypertension, anemia, uremia, malnutrition, and aortic stenosis. Drug therapy requires great caution in this patient population, and should be begun only after careful consideration of risk and benefit. 1 figure. 6 tables. 38 references. (AA-M). •
Williams Syndrome Source: Journal of Clinical Pediatric Dentistry. 19(4): 301-304. Summer 1995. Summary: This article reports a case of Williams syndrome, a disorder characterized by multiple anomalies, including mental deficiency, an unusual Elfin facies, supravalvular aortic stenosis, and many other cardiovascular anomalies, prenatal and postnatal growth deficiencies, infantile hypercalcemia, impaired renal function and nephrocalcinosis, microcephaly, perceptual and motor function problems, micrognathia, and many dental anomalies. Williams syndrome is a rare syndrome, but it can usually be diagnosed first at dental clinics because of the typical oral and facial features. The authors report the case of an 8 year old Turkish boy with Williams syndrome, giving particular attention to the oral and dental anomalies and the dental treatment procedures that can be followed for these patients. The etiology of high caries rate and anomalies such as delayed dentition (both present in this case) are from delayed mineralization, which is related to infantile hypercalcemia. Since dental treatment of patients with mental retardation is difficult when only using local anesthesia, general anesthesia may be preferred. But many cases cannot be rendered with general anesthesia because of the severity of the cardiac problems. Because of these systemic problems and mental retardation, early dental evaluation and parental counseling for preventive dental regimens have an utmost significance in these medically compromised patients. 8 figures. 2 tables. 9 references. (AA-M).

Williams Syndrome: Report of a Case Source: Oral Surgery, Oral Medicine, Oral Pathology. 74(6): 756-759. December 1992. Summary: Williams syndrome is a rare anamoly, consisting of idiopathic hypercalcemia that is normally accompanied by aortic stenosis, moderate mental retardation, and a characteristic elfin face. This disease can eventually be detected in the dental or orthodontic clinic, because people with this syndrome have severe dental abnormalities. In this article, a unique case of this type is reported. The authors note that, although the genetic bases of the disease are not clear, an underlying disorder may exist, implying a dominant autosomal inheritance with a great variety of forms. 7 figures. 14 references. (AA-M).

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 aortic stenosis. 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 aortic stenosis. The following is typical of the type of information found when searching the CRISP database for aortic stenosis: •
Project Title: ALTERED SIGNALING IN CARDIAC HYPERTROPHY AND FAILURE Principal Investigator & Institution: Scholz, Peter M.; Professor; Surgery; Univ of Med/Dent Nj-R W Johnson Med Sch Robert Wood Johnson Medical Sch Piscataway, Nj 08854 Timing: Fiscal Year 2001; Project Start 01-JUL-1988; Project End 30-JUN-2002 Summary: Adaptation of the heart to chronic pressure overload leads to cardiac hypertrophy and alterations in signal transduction to compensate for increased sympathetic tone and work. These adaptive changes lead to increases in cGMP levels down regulation of beta adrenergic receptors. The hypothesis of this proposal is that the negative functional effects of cGMP contribute to compensation in hypertrophy and that, when this endogenous brake fails, heart failure develops. The specific aim is to determine if the mechanism of cGMP's negative impact is through changes in cAMP via the cGMP-dependent cAMP phosphodiesterases (PDE) or through interactions of protein kinase G on A and C, to elucidate which of these mechanisms causes the hypertrophied heart to decompensate by contrasting the alterations in the signaling cascade of the compensated with that of failing hypertrophied heart (rapid pacing) and to confirm their relevance by further chronic alteration of the cAMP PDEs. Cardiac myocytes isolated from adult dogs with normal, hypertrophied (aortic stenosis model) and failing hearts will be used to determine the effects of postproduction changes in signaling on function (video edge detection) and O2 consumption (PO2 electrode). The relative importance of these mechanisms in controlling regional function and O2 costs will be tested in the intact heart. The in vivo experiments will be conducted in anesthetized, open-chest dogs 6 months after induction of hypertrophy with or without failure and compared to controls. Regional myocardial work will be assessed from segment length (ultrasonic dimension crystals) and contractile force (miniature force gauges). O2 consumption of the same area will be determined from regional blood flow (radioactive microspheres or flow probe) and regional O2 saturation of hemoglobin (microspectrophotometry). These physiological measurements will be combined with biochemical assays for cAMP, cGMP, the respective phosphodiesterases and protein kinases A, G and C and correlated with Ca transient measurements. The ultimate goal is to determine the mechanism that initiates decompensation and leads to congestive heart failure. Impact of the proposal: the understanding of these mechanisms will permit the

Project Title: CARDIAC ANGIOTENSIN: HYPERTROPHY AND FAILURE Principal Investigator & Institution: Lorell, Beverly H.; Associate Professor of Medicine; Beth Israel Deaconess Medical Center St 1005 Boston, Ma 02215 Timing: Fiscal Year 2001; Project Start 01-JUN-1995; Project End 31-JUL-2005 Summary: (the applicant's description verbatim): The angiotensin II type 2 (AT2) receptor predominates in the left ventricle (LV) in hypertrophy and heart failure, and AT2 receptor activation suppresses growth and promotes apoptosis in vitro. This project will test the overall hypothesis that AT2 receptor signaling in vivo mediates anti-growth and pro-apoptotic effects in pressure overload hypertrophy. We will use transgenic mice with ventricular targeted overexpression of the AT2 receptor driven by the MLC2V promoter which are subjected to ascending aortic stenosis. Functional consequences will be studied by echocardiography and hemodynamic measurements, analysis of isolated myocyte contraction and intracellular ion regulation using fluorescence video microscopy, and confocal microscopy analysis of in situ cell morphology and apoptosis. Signaling pathways will be studied by immunohistochemistry and immunoblotting using antibodies to specific signaling molecules and identification of phosphorylation state. The Specific Aims are: Aim 1. To determine if AT2 receptor overexpression in transgenic mice suppresses in vivo hypertrophic growth in response to chronic systolic pressure overload from aortic stenosis. We predict that AT2 receptor overexpression severely depresses the development of LV hypertrophy, and promotes the rapid development of heart failure and premature death. Aim 2. To test the hypothesis that AT2 receptor overexpression promotes myocyte apoptosis in mice with pressure overload. Apoptosis will be identified by in situ Tunel and ligase assays using confocal microscopy, and complementary measurement of cytochrome c leakage to the cytosol. Aim 3. To determine if AT2 receptor overexpression in vivo modifies myocyte contractile function, and interferes with Ang II mediated inotropy. These experiments will employ measurements of contractility as well as intracellular pH and Ca2+ in isolated mouse myocytes, and test the hypothesis that AT2 receptor activation suppresses the coupling of Ang II with forward Na+-H+ exchange. Aim 4. To determine if AT2 receptor overexpression in vivo activates the kinin-cGMP pathway. In vitro studies suggest that this system contributes to AT2 receptor signaling, but its contribution, if any, in the adult heart is not understood. Measurements will be made of cGMP levels and kininogenase activation in LV tissues (and atrial tissues in which the transgene is minimally expressed). In addition, the functional effects of inhibition of this pathway on cardiac growth and hemodynamic performance will be tested in vivo in mice with AT2 overexpression, in presence and absence of pressure overload. These integrated molecular physiology studies, which examine in vivo and cellular cardiac physiology, will provide new insights regarding cardioprotective versus deleterious effects of AT2 receptor activation in hypertrophy and heart failure.

Studies

Timing: Fiscal Year 2001 Summary: Elastin is the major extracellular matrix component of large blood vessels. It is the protein responsible for the elastic recoil properties of these tissues and plays an important role in defining vascular will compartments. Several human diseases have recently been linked to mutations in elastin. The objective of this proposal is to better understand how these mutations alter the functional properties of the elastic fiber leading, ultimately, to vascular pathology. Our focus will be supravalcular aortic stenosis, an inherited obstructive vascular disease that causes significant narrowing of large systemic and pulmonary arteries. Recently, autosomal dominant SVAS has been linked to the elastin (ELN) locus on chromosome 7. There are two possible explanations for how mutations in elastin cause SVAS: 1) haploinsufficiency, where a half dose of normal elastin is being produced, or 2) abnormal elastic fibers arising from dominant negative elastin mutations. To test these possibilities, we propose to combine in vitro assays for elastin assembly with expression of mutant proteins in transgenic mice to identify the mechanism whereby mutant proteins alter elastic fiber structure and, ultimately, vascular function. Our specific aims are; 1) To characterize ELN mutations in patients with sporadic and autosomal dominant SVS. 2) Determine if the mutant elastin allele is expressed in cells from patients with SVAS. 3) Ascertain whether mutant tropoelastin is capable of incorporating into, or disrupting normal elastic fibers. 4) Develop mouse models that express common ELN mutations found in SVAS and determine how these mutations alter vascular development and function. In addition to providing answers to the pathogenesis of SVAS, these studies will undoubtedly be instructive in identify domains of elastin that play a critical role in the normal function of this important protein.

Project Title: ELASTIN GENE MUTATIONS IN SKIN AND VASCULAR DISEASES Principal Investigator & Institution: Urban, Zsolt; None; University of Hawaii at Manoa 2500 Campus Rd Honolulu, Hi 96822 Timing: Fiscal Year 2001; Project Start 01-SEP-1999; Project End 31-AUG-2003 Summary: The overall goal of this proposal is to understand the role of mutations in the elastin gene in the pathogenetics and pathobiology of two heritable diseases of elastic tissue, supravalcualar aortic stenosis (SVAS) and autosomal dominant cutis laxa (ADCL). Elastin is the major protein in elastic fibers and responsible for the recoil properties of all elastic tissues, including skin and blood vessels. Over the last few years, several investigators, including ourselves, have demonstrated that mutations in the elastin gene are responsible for two phenotypically distinct heritable disorders. SVAS is an autosomal dominant vascular disease characterized principally by arterial wall stenosis, with no obvious pulmonary or dermal phenotype. In contrast, ADCL is primarily a skin disorder characterized by inelastic skin with minimal vascular disease. Both disease have been shown recently to be due to mutations in the elastin gene. While it is not clear how mutations in the gene will result in two separate diseases, from preliminary results presented in the proposal, it seems that the nature of the mutations in the elastin gene will determine either a vascular or a dermal phenotype. The four specific aims that we have outlined in this proposal are intended to elucidate the detailed relationship between the type of mutations in the elastin gene and the influence of these mutations on both tissues morphogenesis, and elastin fiber assembly and elastin tissue function. Changes in elastin gene expression are a characteristic feature of many common elastic tissue disorders ranging from aortic aneurysms to keloids and we expect new insights from our proposed work on SVAS and ADCL to have a significant

Project Title: FUNCTION OF GENES IN WILLIAMS SYNDROME DELETION REGION Principal Investigator & Institution: Francke, Uta; Professor; Genetics; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2001; Project Start 01-JUL-2001; Project End 31-MAY-2006 Summary: (provided by applicant): With the Human Genome Project promising to provide a catalog of all human genes in the near future, the main challenge of research in the next century is that of functional genomics. The processes that control gene activation and repression in a developmental-stage and cell-type specific manner are fundamental to understanding normal development and discovering the causes of human disease. Spontaneously recurring microdeletions are ideal for a systematic study of the downstream effects of hemizygosity for the defined set of genes in the deletion. Williams-Beuren syndrome (WBS), a neurodevelopmental disorder with a distinct profile of cognitive and behavioral features serves as a model system to study the genetic and molecular basis of cognition, speech, language, and visuo-spatial processing. WBS is caused by recurrent uniform deletions of 1.6 Mb of DNA from chromosome 7q11.23, that arise by inter- or intrachromosomal recombination between flanking duplicated regions. Within the deletion, 16 genes have been identified and characterized. They function as transcription factors, in DNA replication, chromatin assembly, translation, signal transduction and as structural proteins. Only one, the elastin gene has been linked to a specific manifestation, supravalvular aortic stenosis. To evaluate the functional consequences of hemizygosity for the other genes, humans with partial deletions will be identified and mouse models generated with corresponding deletions in the conserved syntenic region on mouse chromosome 5. Target genes of transcription factors and signaling molecules will be identified by microarray studies, comparing gene expression patterns in various tissues from affected humans and deletion mice. Development of a molecular phenotype of WBS links cognitive neuroscience to molecular genetics. Insights gained into the molecular pathways, that lead from the chromosomal deletion to the specific cognitive, behavioral and learning disabilities may have relevance for common developmental disorders, such as attention deficit/hyperactivity disorder and autism, as well as for understanding normal developmental processes.

Project Title: GORDON RESEARCH CONFERENCE ON ELASTIN & ELASTIC FIBERS Principal Investigator & Institution: Sakai, Lynn Y.; Associate Professor; Gordon Research Conferences Box 984, 512 Liberty Ln West Kingston, Ri 02892 Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2002 Summary: (provided by applicant): The Elastin and Elastic Fibers Gordon Research Conference will meet for the 12th time in summer of 2001. This Conference is the premier meeting for scientists interested in elastic fiber biology, biochemistry, and pathophysiology. It is also of interest to scientists working in related areas of connective tissue biochemistry and to those interested in cardiovascular, pulmonary, skin, and skeletal biology. The Elastin and Elastic Fibers Gordon Conference is a unique opportunity for senior and junior scientists from around the world to gather every other year and discuss the latest and most cutting edge developments in research. Since changing its name from the Elastin Gordon Conference (1993 and previous years) to the Gordon Conference on Elastin and Elastic Fibers (1995 and subsequent years), this Conference has been moving from a meeting devoted to a single molecule (elastin) to a broader meeting covering elastic fiber structure, biology, and pathophysiology. Recent Conferences have showcased the discoveries that mutations in genes for elastin and for the fibrillins are mutated in the human genetic disorders supravalvular aortic stenosis and Williams Syndrome (ELN), the Marfan syndrome (FBNI), and congenital contractural arachnodactyly (FBN2). The 2001 Conference will highlight investigations of how mutations in elastic fiber components result in connective tissue pathophysiology. In addition, new insights into the function of elastic fiber components (emilin, the fibulins, the latent TGFb binding proteins) will be discussed based upon gene targeting experiments in mice and other functional studies. Finally, interactions between growth factors and elastic fiber components will be a new emphasis at this Conference.

Project Title: INTRACELLULAR TRAFFICKING OF TROPOELASTIN Principal Investigator & Institution: Davis, Elaine C.; Assistant Professor; Cell Biology; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2001; Project Start 15-DEC-1998; Project End 30-NOV-2002 Summary: Elastic fiber assembly is a complicated process that involves the organization of tropoelastin monomers on a microfibril scaffold and the subsequent crosslinking of these monomers into an insoluble elastin matrix. In the vessel wall, elastic fibers form concentric lamellae that are critical for the structural integrity and function of the vessel. Increasing evidence suggests that in virtually all vascular diseases, some aspect of elastic fiber assembly or structure is affected. Our ability to study these aberrant changes, however, is presently restricted by our limited knowledge of how elastic fibers normally assemble in developing tissues. Although significant advances have been made in the characterization of elastic fiber components, we know remarkably little about the intracellular events involved in their targeting and eventual secretion from the cell. Recently, we have shown that within the secretory pathway, tropoelastin is a ligand for a 65-kD FK506 binding protein (FKBP65). Since little is known about FKBP65, our first specific aim is to fully characterize the protein by determining its temporal and tissue specific distribution, establishing its intracellular location and topography, and identifying additional ligands for the protein. Since members of the FKBP family are peptidyl- prolyl cis-trans isomerases that have been implicated in folding and trafficking events, the association of tropoelastin with FKBP65 raises the intriguing hypothesis that FKBP65 plays a role in the folding and/or transport of tropoelastin to membrane assembly sites. Our second specific aim, therefore, is to test this hypothesis by studying the direct binding of tropoelastin to FKBP65 in in vitro assays, determining if FKBP65 has isomerization activity on tropoelastin-specific peptides, and investigating the role of FKBP65 in tropoelastin expression, secretion and assembly by treating cells with the immunosuppressant drug, FK506, to disrupt the FKBP65-tropoelastin interaction. In our third specific aim, we will extend our present studies on the intracellular trafficking of tropoelastin by identifying additional proteins and chaperones that associate with tropoelastin in the secretory pathway and by characterizing the post-Golgi transport of the protein based on our preliminary data that supports a role for an acidic compartment in the transport of tropoelastin to the cell surface. Results from these studies will not only provide fundamental information concerning the intracellular events required for normal elastic fiber assembly, but will ultimately establish an important basis for future studies on elastic fibers in a number of vascular diseases, such as supravalvular aortic stenosis, hypertension and aortic aneurysms.

Project Title: LOAD INDUCED CARDIAC HYPERTROPHY IN THE ADULT MAMMAL Principal Investigator & Institution: Cooper, George I.; Medicine; Medical University of South Carolina 171 Ashley Ave Charleston, Sc 29425 Timing: Fiscal Year 2001; Project Start 01-AUG-1993; Project End 31-JUL-2003 Summary: The hypothesis upon which this Program Project Grant is based is that hemodynamic loading of the heart is the primary regulator of its structure and function. While the prediction of this hypothesis are equally applicable to cardiac physiology, the question which we have chosen as the subject of these studies is that of how increased load interacts directly with the heart to explain the causes and consequences of cardiac hypertrophy. In this context, the five individual projects form a closely interrelated set
Studies

of studies. In Project #1, Dr. McDermott, who has used cardiocytes and tissue loaded in vitro, and myocardium loaded in vivo, to define translational control in hypertrophy, will extend this work to the question of whether the increased translationally active eIF4E that he finds is causally linked to hypertrophy. In Project #2, Dr. Carabello will build on this studies showing less hypertrophy in mitral regurgitation than aortic stenosis, with ventricular remodeling in the former but not in the latter, by asking how failure to re-normalize wall stress induces this process. In Project #3, Dr. Menick will extend his discovery of elements requisite for cardiac expression of the Na-Ca exchanges gene, as well as a novel element important for cardiac expression and hypertrophic upregulation, to studies of transcriptional regulation of a gene encoding a protein critical to calcium homeostasis in hypertrophy. In Project #4, Dr. Cooper will extend his work showing augmented microtubules in hypertrophied myocardium and microtubule stabilization and upregulation of microtubule proteins, to an attempt to establish a cause-and-effect relationship between these changes in gene expression and contractile dysfunction, with an emphasis on the role of isoform-specific changes in tubulin expression. Also, in a new initiative, we will explore our recent discovery suggesting that hypertrophic microtubule alterations may have a role in the altered beta-adrenergic receptor function suggesting that hypertrophic microtubule alterations may have a role in the altered beta- adrenergic receptor function characteristic of cardiac hypertrophy. In the new Project #5, Dr. Zile will exploit his development of a unique, phenotypically stable isolated adult cardiocyte model to study the signalling pathways by which load is coupled to growth in the adult cardiocyte. Thus, the first and fifth projects are concerned with causes of load-induced cardiac hypertrophy in the adult, with the first focused on inducting of increased protein synthesis, and the fifth focused on signals for that induction. The other three projects are concerned with consequences of load-induced cardiac hypertrophy in the adult, being focused on mechanisms by which changes in structural and regulatory elements, whether intracellular or extracellular, alter contractile function and its regulation in cardiac hypertrophy.

Project Title: MEDIATORS OF VASCULAR CALCIFICATION AND BONE DISEASE Principal Investigator & Institution: Giachelli, Cecilia M.; Associate Professor; Bioengineering; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-MAY-2005 Summary: (provided by applicant): Vascular calcification is an actively regulated process contributing to increased morbidity and mortality in, patients with uremia, diabetes, aortic stenosis and bioprosthetic heart valves. Epidemiological studies have linked vascular calcification with osteoporosis and cardiovascular disease, suggesting that common regulatory mechanisms exist, and that ectopic calcification may increase the risk of heart disease. In human blood vessels and valves, both diffuse calcification and ectopic bone have been observed under pathological conditions. The relationship between these types of mineralization is unclear. It is also unknown if media or intimal vascular calcification contributes to formation and/or progression of atherosclerotic lesions. We hypothesize that mineral deposition in blood vessels involves mediators including osteopontin (OPN), osteoprotegerin (OPG) and matrix gla proteins (MGP), that also critically control formation of the skeleton, and that once mineral forms in the vessel wall, an adaptive response ensues and initiates cellular differentiation and inflammatory mechanisms that 1) lead to neointima formation and hence increased susceptibility to plaque formation, and 2) mimic endochondral bone formation that may

explain the appearance of ectopic bones in calcified vascular lesions. In order to identify common mechanisms! controlling bone and vascular calcification, and to understand the relationship between vascular calcification, cartilaginous metaplasia, and arterial lesion development, three aims are proposed. Aim I will determine the mechanism of medial vascular calcification, neointimal formation, and cartilaginous metaplasia in MGP X OPN mutant mice. Aim 2 will determine the mechanism of bone and tooth defects found in MGP X OPN mice. Aim 3 will determine the effect of hyperlipidemia on cartilaginous metaplasia, vascular calcification and osteoporosis in a mouse model of atherosclerosis.

Project Title: MOLECULAR DETERMINANTS OF PEDIATRIC HEART DISEASE Principal Investigator & Institution: Kelly, Daniel P.; Pediatrics; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2001; Project Start 01-JAN-1999; Project End 31-DEC-2003 Summary: The long term objective of this Pediatric SCOR is to determine the molecular bases of defective human cardiac morphogenesis and myocardial function which results in congenital heart disease (CHD) and pediatric cardiomyopathy (CM). The underlying hypothesis is that single gene defects at multiple loci in the human genome cause most pediatric cardiac structural and myopathic diseases. Two corollaries will also be explored, that (i) genetic abnormalities at the same locus have variable expressivity and can result in different phenotypes and (ii) genotype- phenotype correlations exist. A multi-disciplinary approach encompassing 14 investigators, 6 clinical and laboratory projects, and 4 core units at three locations is proposed. Molecular genetic studies of a St. Louis family with dominantly-inherited dilated CM; CM or sudden death secondary to mutations in mitochondrial fatty acid oxidation enzymes; patients with CHD associated with at the human at the human 8p23 locus encompassing the GATA-4 gene, a critical transcription factor in heart; elastin in heart; elastin mutations in supravalvar aortic stenosis; and dominantly-inherited atrial septal defects (ASD) mapped to 5p and 5q are the clinical focus. Mouse gene ablation and transgenic models to delineate (i) the pathogenesis of CM and sudden death in fatty acid oxidation defects, (ii) the essential role and downstream targets of GATA-4 expressed in mouse embryonic endoderm for mesoderm-mediated and downstream morphogenesis, (iii) the mechanisms by which elastin mutations disrupt elastic fiber assembly and vasculogenesis, and (iv) the mechanisms by which mutant mouse homologs of genes defective in human familial ASD result in CHD will be created. The molecular role of syndecans in determination of left-right asymmetry will be studied in the uniquely-manipulable Xenopus embryo system as a model for mechanisms underlying human heterotaxy syndromes and CHD. Characterization of defective human genes causing pediatric heart disease and the mechanisms through which mutations alter cardiac development and myocardial function is necessary before manipulations to prevent CHD and inherited CM are feasible.

Summary: (provided by applicant): This proposal is for a new K08 application which proposes a detailed plan for the candidate's research and a 4-year goal driven plan for further career development. The candidate's career goal is to become a successful independent scientific investigator. A career development plan is described that delineates the specific goals over the award period and the mechanisms that will be used to achieve them. Through didactic training and ongoing supervision through mentors and advisory committee, the candidate expects to 1) further develop as a basic science investigator, 2) conduct the proposed study with the highest degree of quality 3) present and publish studies in valvular heart disease at National conferences and leading journals 5) compete for advanced sources of funding and 6) develop insights in to the pathogenesis of valvular heart disease. The underlying mechanism for the pathogenesis of calcific aortic stenosis is unknown. This trend is becoming more pronounced with the aging population. Clinical studies indicate parallel risk factors for vascular atherosclerosis and aortic valve disease, the principle causative factor is elevated cholesterol levels. Due to these clinical observations, the PI has developed a translational approach to studying aortic valve disease. It is our hypothesis that calcification of the aortic valve is a direct result of valvular cellular transformation to an osteoblast phenotype that is initiated by hypercholesterolemia. The PI plans to test the hypothesis by the following specific Aims: Aim 1: Using the in vivo rabbit model, analyze the effects of hypercholesterotemia with and without statins in the atherosclerotic and proliferative aortic valve. Aim 2: Using the in vivo rabbit model, analyze the effects of hypercholesterolemia with and without statins in the calcification and mineralization of aortic valve. Aim 3: Using the in vivo rabbit model, determine the specific signaling pathways in the aortic valve which mediate the development of aortic valve atherosclerosis and osteoblastogenesis. Aim 4: Imaging the in vivo rabbit model of aortic valve disease. These studies provide the first in vivo model of aortic valve calcification which correlate the epidemiologic studies of atherosclerotic risk factors to the development of calcific aortic valve disease. If hypercholesterolemia stimulates the development of calcification in the aortic valve then the use of medical therapy such as HMG CoA reductase medications may have a role in the medical therapy of calcific aortic stenosis.

Project Title: POTENTIAL ROLE OF TFII-I IN IMMUNODEFICIENCY Principal Investigator & Institution: Roy, Ananda L.; Professor; Pathology; Tufts University Boston Boston, Ma 02111 Timing: Fiscal Year 2001; Project Start 01-MAR-2000; Project End 28-FEB-2005 Summary: TFII-II is an important multi-functional transcription factor that links events to transcription in several genes. TFII-I is constitutively associated with Bruton's tyrosine kinase (Btk), a non-receptor tyrosine kinase that is essential for normal B cell function, as its mutation causes X-linked agammaglobulinemia (XLA) in humans and Xlinked immune deficiency (xid) in mice. We propose that TFII-I is an important and novel component in linking Btk-mediated signaling to transcription in B cells. Furthermore, the TFII-I gene gets deleted in William's syndrome (WS) which is a neurodevelopmental disorder with multi-system manifestations, including supravalvar aortic stenosis, hypercalcemia in infancy, mental retardation and cognitive defects. Thus, TFIII appears to be involved in two genetic disorders: William's Syndrome and X-linked agammaglobulinemia (XLA). Knowledge gained from these studies may help us better understand a critical Btk dependent pathway that links B cell receptor mediated signal transduction to B cell specific transcription. These studies may also ultimately help
14
Aortic Stenosis
identify potential target gene(s) that are affected by mutations in Btk. Importantly, these studies may establish possible connections between the neuro-developmental disorders (as in WS) and immuno-developmental disorders (as in XLA). Toward a better understanding of TFII-I function in Btk mediated immune response, we will first map the region(s) in TFII-I important for its physical and functional interactions with BTK. We will determine by deletion and point mutation the region(s) in TFII-I that is important for its interaction with Btk, followed by mapping the sites in TFII-I that are tyrosine phosphorylated by Btk in vitro and in vivo by a combination of site directed mutagenesis, phosphopeptide, finger printing, and mass spectrometric analysis. We will also analyze these mutants in functional transient transfection assays. To determine the functions of TFII-I and its biochemical interactions with Btk in B cells, we will employ in vivo transcriptional analysis. To determine the functions of TFII-I and its biochemical interactions with Btk in B cells, we will employ in vivo transcriptional analysis followed by the interaction studies by co- immunoprecipitation and ectopic expression of mutant forms of TFII-I in B cells. We will also stably express wild type and mutant forms of TFII-I, and Btk in B cell lines, and genetically delete TFII-I from chicken B cells. Finally, to ascertain the localization of TFII-I in the absence and in the presence of non-activated versus activated Btk, first, we will co-express various mutants of TFII-I with Btk in COS cells. Subsequently, we will employ freshly isolated primary splenic B cells derived from wild type, xid and Btk-/- mice and study the localization and tyrosine phosphorylation of TFII-I in the absence and in presence of B cell receptor signaling.

Project Title: REGULATION OF ENDOTHELIAL MMP EXPRESSION AND FUNCTION Principal Investigator & Institution: Galis, Zorina S.; Associate Professor; Medicine; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2007 Summary: (provided by applicant): Numerous observations support the connection between atherosclerotic lesion progression and disturbed blood flow. Changes that allow lesion development require the matrix-degrading action of matrix metalloproteinases (MMPs), which have emerged as key agents of vascular wall remodeling. Due to their destabilizing action, understanding MMP control and function may have important applications for managing acute cardiovascular events. However, little is known about MMP regulation in endothelial cells (EC), the flow sensor of the arterial wall. We propose to investigate the hypothesis that disturbed flow mediates the action of EC MMPs. Previous in vitro studies indicate that oscillatory shear increases oxidative stress in cultured EC and decreases cell viability. We previously demonstrated that reactive oxygen species (ROS) increase MMP expression and activity. We presently hypothesize that shear-induced oxidative stress increases EC MMP production and activity, specifically of the inducible MMP-9, in areas of disturbed flow. We further propose that increased MMP activity has functional consequences related to degradation of EC basement membrane, including increased EC turnover, and potentially EC loss, responsible to plaque erosion, the major failure mode of otherwise stable plaques. To investigate this potential mechanism, which would connect disturbed blood flow, oxidative stress, and endothelial dysfunction via increased MMP activity, we propose these specific aims: I. To investigate whether shear or ROS modulate expression and/or activity), of EC MMP-2 and -9; 2. To identify regulatory elements involved in MMP-9 induction by shear or ROS; 3. To investigate whether effects of disturbed shear upon EC MMP expression/activity are mediated, via oxidative stress; 4.

To assess whether EC MMPs mediate increased basement membrane degradation and cell turnover under disturbed shear. Unidirectional and disturbed blood flow will be modeled in vitro using cultured human and mouse EC and in vivo, by creating a stenosis by banding of mouse aorta. We will investigate EC MMP transcriptional regulation, mRNA stability, protein, and activity. Computed flow patterns of the aortic stenosis will be superimposed with the in vivo map of EC MMP induction obtained from transgenic mouse overexpressing the MMP-9 promoter driving a LacZ reporter (MMP-9/LacZ), and with maps of EC dysfunction and loss. Specific contribution of MMPs and oxidative stress will be verified in vitro and in vivo using chemical inhibitors and relevant strains of genetically deficient mice. Our preliminary results support our hypothesis and demonstrate the feasibility of these studies, which should help elucidate the contribution of EC-derived MMPs to endothelial dysfunction and progression of atherosclerosis towards acute clinical events.

CARDIAC
LOADING--HYPERTROPHY
VS
Principal Investigator & Institution: Carabello, Blase A.; Professor and Vice Chairman; Medical University of South Carolina 171 Ashley Ave Charleston, Sc 29425 Timing: Fiscal Year 2001 Summary: During our initial funding period, we examined the mechanisms by which volume overload versus pressure overload caused hypertrophy. We found that despite severe volume overload, there was no increase in protein synthesis rate and that hypertrophy occurred by accumulation due to a decrease in degradation rate. This mechanism produced substantially less hypertrophy than in pressure overload where an increase in protein synthesis rate causes robust cardiac growth. The inadequate hypertrophy in mitral regurgitation, in myocardial infraction and in even some subjects with aortic stenosis, leads to increased wall stress and cardiac dilatation. Although cardiac dilatation initially permits the left ventricle to eject an increased stroke volume, dilatation eventually leads to increasing wall stress, and left ventricular dysfunction. Building on our observations during the first funding period we will now explore a key mechanism leading to the maladaptive situation of cardiac dilatation with increased wall stress. We will test the hypothesis that when there is inadequate hypertrophy to normalize diastolic wall stress, dilatation occurs and this dilation is in large part due to activation of matrix metalloproteases (MMP's). Specific aims of the current funding period are to 1). to examine matrix metalloprotease activity in five situations: a) normal dogs, b) dogs with aortic stenosis manifesting adequate hypertrophy, and no dilatation, c) dogs with aortic stenosis, inadequate hypertrophy, and cardiac dilatation, d) dogs with myocardial infarctions and dogs with mitral regurgitation, 2) to examine extracellular matrix and collagen architecture in connection with MMP activation, 3) to use MMP inhibitors to prevent activation and remodeling, and 4) to identify mechanisms controlling MMP activity. Using our models of human diseases we will define one of the major mechanisms of cardiac dilatation, will establish the regulation of MMP's and will further test our hypothesis by inhibiting dilatation with an MMP inhibitor. These studies will enhance both the scientific understanding of cardiac remodeling and also will address a major clinical problem causing significant cardiac mortality and morbidity.

Project Title: ROLE OF SEROTONIN IN SYMPATHETIC FUNCTION Principal Investigator & Institution: Scrogin, Karie E.; Pharmacol & Exper Therapeutics; Loyola University Medical Center Lewis Towers, 13Th Fl Chicago, Il 60611 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2007 Summary: Following a critical amount of blood loss, compensatory neural responses that normally help maintain blood pressure suddenly fail, causing vasodilation, profound bradycardia and life-threatening hypotension. The central nervous system mechanisms that mediate this sympatholytic response are unknown. A more comprehensive understanding of such mechanisms could lead to novel treatments for circulatory shock and other disorders with aberrant activation of sympatholytic reflexes such as myocardial infarct of the inferoposterior wall of the heart, exertional syncope associated with aortic stenosis or neurogenic syncope. In vivo models devised to examine these responses have been limited due to the effects of anesthesia on autonomic function. The objective of this proposal is to elucidate the role of hindbrain serotonergic cellular- and receptor mediated mechanisms in the sudden loss of sympathetic activity that accompanies severe blood loss in the conscious rat. Specifically, studies have been designed to identify the source of serotonin and the receptor populations that mediate sympathetic withdrawal during hemorrhage. The proposed experiments involve novel uses of classic physiological models to study the role of discrete hindbrain neuronal and receptor populations in the regulation of sympathetic function in unanesthetized rats. Anatomical studies that combine neuronal tract tracing with immunhistochemical markers of neuronal phenotype and function will be used to determine the source and projection site of serotonin involved in sympathetic reflexes. The novel techniques outlined in this proposal will help to determine hindbrain serotonergic cellular and receptor function on sympathetic regulation in general and on hemorrhage responses in particular, a goal which has, until now, been hampered by the confounding influence of anesthesia on hemorrhage responses and serotonergic function.

Project Title: SITOSTEROLEMIA Principal Investigator & Institution: Salen, Gerald; Professor of Medicine; Medicine; Univ of Med/Dent Nj Newark Newark, Nj 07103 Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2004 Summary: The major aims of this grant are to define the molecular, biochemical, and clinical defects in sitosterolemia. In this recessively inherited disease, homozygotes show accelerated atherosclerosis with aortic stenosis, fatal myocardial infarctions, tendon and tuberous xanthomas, hemolytic episodes with deformed erythrocytes and thrombocytopenia, and attacks of disabling arthritis. Chemically, plant sterols (sitosterol, stigmasterol, campesterol, and avenosterol) and their respective 5alphadihydro derivatives (sitostanol and campestanol) and cholestanol accumulate in all tissues except brain because of enhanced intestinal absorption and reduced hepatic removal. In addition, cholesterol biosynthesis is discordantly down-regulated in monocytes with upregulated LDL receptors to produce increased cholesterol and plant sterol deposits such that the cells resemble atherogenic foam cells. Key research objectives are (1) locate and clone the sitosterolemia gene responsible for hyperabsorption that has been mapped to 2p21, sequence mutations, and elucidate the mechanism by with the mutated product permits unrestricted uptake and transport of plant sterols through the enterocyte. Strategies include fine mapping with a dense set of microsatilliate markers to narrow the abnormal gene region to approximately 1cM,

construction of YAC contig and BAC contig with critical cDNAs from the suspected and adjoining regions. Sequence candidate genes from the region for possible mutations. DNA from 40 affected homozygotes from 30 sitosterolemic families have been assembled. (2) Investigate cholesterol and plant sterol metabolism in 3 rat models where campesterol and sitosterol constitute approximately 15 percent of the plasma sterols similar to human sitosterolemia. In these models, we propose to measure sitosterol and cholesterol absorption, assess cholesterol biosynthesis (inhibited in human sitosterolemia) and evaluate the effect of long term cholesterol feeding on development of atherosclerosis, plant sterol and cholesterol accumulation and metabolism. (3) Examine the conversion of sitosterol (24-ethyl cholesterol) to cholic acid and chenodeoxycholic acid and ascertain the pathway. Sitosterolemia is a rare disease but understanding the mechanism of enhanced sterol absorption and accumulation will provide key information to formulate better treatment of atherosclerosis in the general population.

Project Title: SOLID STATE NMR STUDIES OF MINERALIZED ELASTIN Principal Investigator & Institution: Kumashiro, Kristin K.; University of Hawaii at Manoa 2500 Campus Rd Honolulu, Hi 96822 Timing: Fiscal Year 2001; Project Start 24-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant): This project will use high-resolution solid-state nuclear magnetic resonance (NMR) to characterize the conformational changes which accompany the mineralization of elastin in the heritable vascular and dermal disorder called pseudoxanthoma elasticum (PXE). The normal elastic fiber lends resiliency to vertebrate tissues, such as the skin and blood vessels. Its major protein component is elastin, which imparts elasticity to these tissues. Elastin is an insoluble, amorphous, and extensively crosslinked biopolymer, and there are no high-resolution crystallographic or solution NMR structures for this protein. Changes in elastic fiber morphology have been associated with the loss of elasticity in heritable and acquired disorders such as Marfan syndrome, supravalvular aortic stenosis, and aortic aneurysms. And, recent work by other laboratories strongly suggests that the calcification of the elastic fibers in PXE patients is a secondary consequence of a primary alteration in the structure and/or assembly of elastin. Therefore, we propose that PXE effects the introduction of new components or abnormal concentrations of typical components in elastic tissue. The abnormal chemical conditions induce conformational changes of elastin, and it is this abnormal state which undergoes mineralization. To obtain the most definitive descriptions of structural changes to elastin on the molecular level, high-resolution solid-state NMR spectroscopy will be utilized. These studies will identify the structural differences between normal elastin and several calcified states, as produced in welldefined chemical conditions. And, the characterization of the abnormal elastin, as found in the tissue of a PXE patient, will be indicative of the conditions which accompany, or even induce, mineralization.

Aortic Stenosis
Summary: (provided by applicant): Congenital heart disease (CHD) is the most common major birth defect affecting 4-8 per 1000 livebirths. Left-sided cardiac defects (LSCD) include valvar aortic stenosis, coarctation of the aorta and hypoplastic left heart syndrome, and account for at least 10% of CHD. Although LSCD are associated with significant morbidity and mortality, their etiology is largely unknown. Very few, if any, environmental causes have been identified and LSCD are associated with relatively few consistent chromosomal alterations or genetic syndromes. Nonetheless, studies point to a genetic contribution to these conditions, given an increased risk of recurrence and small, multiplex families. LSCD appear to share a common genetic etiology as different defects can occur in different members of a single family. Large multiplex families or affected sibling pairs amenable to genome wide linkage analyses are very rare, consistent in part with a complex mode of inheritence. The goal of this program is to identify genetic factors that contribute to the etiology of LSCD using techniques which dissect complex disorders. This investigation proposes that there are susceptibility loci and novel mutations that contribute to the etiology of LSCD. To investigate this hypothesis, this program will: (I) identify and characterize common susceptibility loci for LSCD using family-based association studies, and (II) identify and characterize rare or novel mutations in candidate genes in subjects with LSCD. A large cohort of subjects has been recruited. Family based association analyses and mutation analyses have already identified potential disease-related alleles and mutations respectively. To accomplish our goals, we will continue to recruit subjects, genotype them for a chosen set of common variants, and test them for association to LSCD. The role of maternal genetic effects for a subset of the putative susceptibility loci will also be evaluated. To complement the association studies, we will screen subjects for mutations of candidate genes by Conformation Sensitive Gel Electrophoresis and direct sequencing. If a sequence variant is identified, control populations will be tested for the same variant to determine disease relevance. The functional significance of mutations will also be assessed. This investigation will begin to dissect the genetic factors that contribute to the development of LSCD. The findings will allow for improved understanding of the disease-mechanism, more precise family counseling, and may identify preventive measures. In addition, these investigations will lead to future studies that assess the relationship of genotype to clinical outcome, and allow us to improve upon our clinical management accordingly.

Project Title: THE MOLECULAR GENETIC BASIS OF CARDIAC DEFECTS Principal Investigator & Institution: Wenstrom, Katharine D.; Professor of Obstetrics and Gynecology,; Obstetrics and Gynecology; University of Alabama at Birmingham Uab Station Birmingham, Al 35294 Timing: Fiscal Year 2002; Project Start 21-JAN-2002; Project End 31-DEC-2003 Summary: (Provided by Applicant): We hypothesize that certain congenital cardiac malformations are caused by hypomethylation at the cellular level during organogenesis, leading to abnormally slow tissue growth and abnormal cell migration. Cellular methylation status strongly influenced by folic acid nutriture and the enzyme methylene tetrahydrafolate reductase (MTHFR) hypomethylation is possible if an inadequate amount of folate reaches the multiplying cells or the fetus inherits mutation in MTHFR. To test this hypothesis, we will access the University of Alabama's Congenital Heart Disease Collection, a multidisciplinary teaching and research registry of archived heart specimens with cardiovascular malformations. This registry, established and maintained by one of the co-investigators (0 F-P), contains over 550 that

have been catalogued by lesion group and cross referenced by individual defect, with all known etiologies and/or diagnoses (e.g. aneuploidy, genetic syndrome, teratogen exposure, etc) noted. Approximately 100 cardiac specimens representing each of the five basic mechanisms of cardiac development will be selected for study. That is, we will include defects caused by abnormally slow tissue growth (hypoplastic left or right ventricle, aortic stenosis, bifid aortic valve, coarctation of the aorta, pulmonary atresia), abnormally cell migration (conotruncal defects), extraneous cell, (Ebstein anomaly), abnormal growth of the extracellular matrix (AV canal), and abnormal targeted growth (anomalous pulmonary venous return). We will also study a control group of similarly archived normal cardiac specimens. After employing a novel procedure to remove the formalin, DNA will be extracted from the abnormally and normal cardiac tissue samples and tested for the presence or absence of two well-characterized MTHFR mutations. We will then quantitate level of methylation in abnormal and normal heart tissue via an assay utilizing 3H]-methyl-S-adenosylmethionine an extracted genomic DNA. Finally, the specific location of any hypomethylated tissue within each cardiac structure will be determined by exposing representative sections of cardiac tissue to anti Smethylcytosine antibody. If our hypothesis is correct, cardiac defects resulting from abnormally slow tissue growth and abnormal cell migration will be the most hypomethylated. Additionally, confirmation of our hypothesis would suggest that certain types of cardiac malformations might be prevented by folic acid supplementation Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: THE ROLE OF FIBULIN-5 IN CARDIOVASCULAR REMODELING Principal Investigator & Institution: Yanagisawa, Hiromi; Molecular Biology; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2008 Summary: (provided by applicant): The tunica media of the aorta is comprised of alternating layers of smooth muscle cells and elastic fibers (elastic laminae). The molecules and precise mechanisms involved in the formation, organization and maintenance of these layers has yet to be defined. Recently, we have generated a null mutation in the mouse fibulin-5 gene and observed a striking phenotype of systemic elastinopathy due to a disorganization of elastic fibers. Fibulin-5 belongs to a family of similar extracellular matrix proteins and possesses 6 Ca2+ - binding EGF repeats and a single RGD motif. Fibulin-5 is significantly up-regulated in vascular injury suggesting a role in cardiovascular development and remodeling. Solid-phase binding and immunolocalization studies have indicated that fibulin-5 is a Ca2+ -dependent tropoelastin binding protein. We hypothesize that (i) fibulin-5 provides a scaffold that is essential for organizing elastic fibers by connecting elastin to cell surface integrins, (ii) fibulin-5 functions as a negative regulator of neointima formation via an RGDdependent and/or independent mechanism. To test this hypothesis, we propose the following specific aims: (1) to characterize the vascular defects in the fibulin-5 null mice; (2) to define the molecular and genetic interaction of fibulin-5 and elastin; (3) to explore the role of fibulin-5 in cardiovascular remodeling using a model of vascular injury in fibulin-5 null mice. Results from these studies will not only provide fundamental information concerning the role of fibulin-5 in elastic fiber formation, but will ultimately establish an important basis for future studies on fibulin-5 in vascular diseases, such as supravalvular aortic stenosis, atherosclerosis and aortic aneurysms.

E-Journals: PubMed Central3 PubMed Central (PMC) is a digital archive of life sciences journal literature developed and managed by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM).4 Access to this growing archive of e-journals is free and unrestricted.5 To search, go to http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Pmc, and type “aortic stenosis” (or synonyms) into the search box. This search gives you access to full-text articles. The following is a sample of items found for aortic stenosis in the PubMed Central database: •
A Human Vascular Disorder, Supravalvular Aortic Stenosis, Maps to Chromosome 7. by Ewart AK, Morris CA, Ensing GJ, Loker J, Moore C, Leppert M, Keating M.; 1993 Apr 15; http://www.pubmedcentral.gov/articlerender.fcgi?tool=pmcentrez&rendertype=abstr act&artid=46272

Long-Term Results of Apico-Aortic Valved Conduit for Severe Idiopathic Hypertrophic Subaortic Stenosis. by Renzulli A, Gregorio R, De Feo M, Ismeno G, Covino FE, Cotrufo M.; 2000; http://www.pubmedcentral.gov/articlerender.fcgi?tool=pmcentrez&artid=101013
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 aortic stenosis, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “aortic stenosis” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for aortic stenosis (hyperlinks lead to article summaries):

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. 6 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 AORTIC STENOSIS Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and aortic stenosis.
Finding Nutrition Studies on Aortic Stenosis 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 “aortic stenosis” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.
7 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 4. DISSERTATIONS ON AORTIC STENOSIS Overview In this chapter, we will give you a bibliography on recent dissertations relating to aortic stenosis. We will also provide you with information on how to use the Internet to stay current on dissertations. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical dissertations that use the generic term “aortic stenosis” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on aortic stenosis, we have not necessarily excluded non-medical dissertations in this bibliography.
Dissertations on Aortic Stenosis ProQuest Digital Dissertations, the largest archive of academic dissertations available, is located at the following Web address: http://wwwlib.umi.com/dissertations. From this archive, we have compiled the following list covering dissertations devoted to aortic stenosis.

CHAPTER 5. PATENTS ON AORTIC STENOSIS 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 “aortic stenosis” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on aortic stenosis, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Aortic Stenosis By performing a patent search focusing on aortic stenosis, 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 will tell you how to obtain this information later in the chapter.

Diagnosis of Williams syndrome Inventor(s): Keating; Mark T. (Salt Lake City, UT), Leppert; Mark F. (Salt Lake City, UT), Morris; Colleen A. (Las Vegas, NV) Assignee(s): The University of Utah Research Foundation (Salt Lake City, UT) Patent Number: 5,650,282 Date filed: June 7, 1995 Abstract: The invention relates to the identification of the molecular basis of supravalvular aortic stenosis (SVAS) and Williams syndrome. More specifically, the invention has identified that elastin causes or is involved in the pathogenesis of SVAS and Williams syndrome. Molecular variants of the elastin gene contribute to SVAS and Williams syndrome. The analysis of the elastin gene will provide an early diagnosis of subjects with SVAS and Williams syndrome. The diagnostic method comprises analyzing the DNA sequence of the elastin gene of an individual to be tested and comparing it with the DNA sequence of the native, non-variant elastin gene. In a second embodiment, the elastin gene of an individual to be tested is screened for mutations associated with SVAS or Williams syndrome. Presymptomatic diagnosis of SVAS and Williams syndrome will enable practitioners to prevent vascular obstruction using existing medical therapies like beta adrenergic blocking agents. Excerpt(s): The present invention is directed to a process for the diagnosis and prevention of supravalvular aortic stenosis (SVAS) and Williams syndrome. SVAS and Williams syndrome is diagnosed in accordance with the present invention by analyzing the DNA sequence of the elastin gene of an individual to be tested and comparing the DNA sequence to the known DNA sequence of a normal elastin gene. Alternatively, the elastin gene of an individual to be tested can be screened for mutations associated with SVAS or Williams syndrome. Prediction of SVAS and Williams syndrome will enable practitioners to prevent these disdorders using existing medical therapy. The publications and other materials used herein to illuminate the background of the invention or provide additional details respecting the practice, are incorporated by reference and for convenience are respectively grouped in the appended List of References. Supravalvular aortic stenosis (SVAS) is an inherited vascular disorder (1). As its name implies, narrowing of the ascending aorta is a dominant feature of this disease, but other arteries, including the pulmonary arteries, may be affected. If uncorrected, SVAS may lead to increased intracardiac pressure, myocardial hypertrophy, heart failure and death. The incidence of SVAS is estimated to be 1 in 25,000 live births. The vascular abnormalities typical of SVAS can be inherited as an isolated, autosomal dominant trait (1-3) or as part of a second disease, Williams syndrome, a developmental disorder that affects multiple organ systems (2-4). In addition to vascular disease, manifestations of Williams syndrome include hypertension, mental retardation, an unusually gregarious personality, premature greying of the hair, premature aging of the skin, joint laxity early in life followed by joint contractures, dysmorphic facial features and infantile hypercalcemia (4). The relationship between SVAS and Williams syndrome was previously undefined. Occasionally patients with Williams syndrome have been noted in families with SVAS.

Procedure and catheter instrument for treating patients for aortic stenosis Inventor(s): Ariola, Jr.; John P. (East Providence, RI), Cribier; Alain (Maromme, FR), Letac; Brice (Rouen, FR) Assignee(s): Mansfield Scientific, Inc. (Mansfield, MA) Patent Number: 4,777,951 Date filed: September 19, 1986 Abstract: Dilatation procedures and catheter instrument for treating patients having acquired aortic stenosis, typically in which there are calcific deposits on the leaflets of the aortic valve. A dilatation balloon introduced into the stenosed aortic valve via the aorta while the blood circulation of the patient is maintained by the heart via the aortic valve, is inflated to grossly deflect the leaflets of the valve in a manner avoiding blocking the outer portions of the commissures of the valve. This inflating step enables substantial flow of blood through the outer portions of the commissures during systole despite the presence in the valve of the large inflated balloon. By prolonging the inflation for at least 30 seconds, over a large multiplicity of heart beats the calcific deposits are disturbed to increase the pliability of the leaflets and the degree of their opening, in an action found not to produce emboli. The catheter instrument incorporates means for measuring the pressure gradient across the valve and has features facilitating introduction, retention of position during inflation, withdrawal and re-crossing of the valve to achieve progressive enlargement of the aortic valve. Excerpt(s): This invention relates to an aortic valve dilatation instrument and treatment useful for adult patients having aortic stenosis, especially acquired calcific stenosis, a disease which is prevalent in elderly people. Stenosis of the aortic valve has long been known to cause serious diminishment of blood flow from the heart. The critical position of the aortic valve, preceding the arteries that nourish the heart and brain as well as all other parts of the body, makes this a very serious ailment. For those patients sufficiently well to endure the surgery, it has become common to replace the aortic valve with a prosthetic device while the patient is maintained by an extra-corporeal circulation system that by-passes the heart and valve. There is, however, risk with this major surgical procedure and there remains a large population who are too weak or otherwise do not wish to undergo such surgery.

Value prosthesis for implantation in body channels Inventor(s): Cribier, Alain; (Maromme, FR) Correspondence: REED SMITH, LLP; ATTN: PATENT RECORDS DEPARTMENT; 599 LEXINGTON AVENUE, 29TH FLOOR; NEW YORK; NY; 10022-7650; US Patent Application Number: 20030014104 Date filed: May 2, 2002 Abstract: A valve prosthesis which is especially useful in the case of aortic stenosis and capable of resisting the powerful recoil force and to stand the forceful balloon inflation performed to deploy the valve and to embed it in the aortic annulus, comprises a collapsible valvular structure and an expandable frame on which said valvular structure is mounted. The valvular structure is composed of physiologically compatible valvular tissue that is sufficiently supple and resistant to allow the valvular structure to be deformed from a closed state to an opened state. The valvular tissue forms a continuous surface and is provided with strut members that create stiffened zones which induce the valvular structure to follow a patterned movement in its expansion to its opened state and in its turning back to its closed state. Excerpt(s): This application is a continuation of co-pending U.S. patent application Ser. No. 09/795,803, filed Feb. 28, 2001, which in turn is a continuation of U.S. patent application Ser. No. 09/345,924, filed Jun. 30, 1999, now abandoned, which is a National Phase filing of PCT patent application No. PCT/EP 97/07337, filed Dec. 31, 1997 and designating the United States, all of which are incorporated herein by reference. The present invention relates to a valve prosthesis for implantation in body channels, more particularly but not only to, cardiac valve prosthesis to be implanted by a transcutaneous catheterization technique. The valve prosthesis can be also applied to other body channels provided with native valves, such as veins or in organs (liver, intestine, urethra. ).

Valve prosthesis for implantation in body channels Inventor(s): Cribier, Alain; (Maromme, FR), Letac, Brice; (Mont-Saint-Aigant, FR) Correspondence: William H. Dippert, Esq.; Cowan, Liebowitz & Latman, P.C.; 1133 Avenue of the Americas; New York; NY; 10036-6799; US Patent Application Number: 20010007956 Date filed: February 28, 2001 Abstract: The present invention is aimed to provide a valve prothesis (IV) especially used in case of aortic stenosis, which structure is capable of resisting the powerful recoil force and to stand the forceful balloon inflation performed to deploy the valve and to embed it in the aortic annulus. A valve prothesis for implantation in a body channel according to the invention comprises a collapsible valvular structure and an expandable frame on which said valvular structure is mounted. The valvular structure is composed of a valvular tissue compatible with the human body and blood, the valvular tissue being sufficiently supple and resistant to allow said valvular structure to be deformed from a closed state to an opened state. Said valvular tissue forms a continuous surface and is provided with guiding means formed or incorporated within, said guiding means creating stiffened zones which induce said valvular structure to follow a patterned

movement in its expansion to its opened state and in its turning back to its closed state. The valvular structure can be extended to an internal cover which is fastened to the lower end of the valvular structure to prevent from regurgitation. Excerpt(s): The present invention relates to a valve prosthesis for implantation in body channels, more particularly but not only to, cardiac valve prosthesis to be implanted by a transcutaneous catheterization technique. The valve prosthesis can be also applied to other body channels provided with native valves, such as veins or in organs (liver, intestine, urethra,.). The present invention also relates to a method for implanting a valve prosthesis, such as the valve according to the present invention. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

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 aortic stenosis. 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 nonprofit 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 aortic stenosis. 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
94
Aortic Stenosis
following drugs have been mentioned in the Pharmacopeia and other sources as being potentially applicable to aortic stenosis: Ascorbic Acid (Vitamin C) •
Systemic - U.S. Brands: Ascorbicap; Cecon; Cee-500; Cemill; Cenolate; Cetane; Cevi-Bid; Flavorcee; Ortho/CS; Sunkist http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/202071.html
Asparaginase •
Systemic - U.S. Brands: Elspar http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/202072.html
Aspirin, Sodium Bicarbonate, and Citric Acid •
Systemic - U.S. Brands: http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/202072.html
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

The Genome Project and Aortic Stenosis In the following section, we will discuss databases and references which relate to the Genome Project and aortic stenosis. Online Mendelian Inheritance in Man (OMIM) The Online Mendelian Inheritance in Man (OMIM) database is a catalog of human genes and genetic disorders authored and edited by Dr. Victor A. McKusick and his colleagues at Johns Hopkins and elsewhere. OMIM was developed for the World Wide Web by the National Center for Biotechnology Information (NCBI).22 The database contains textual information, pictures, and reference information. It also contains copious links to NCBI’s Entrez database of MEDLINE articles and sequence information. To search the database, go to http://www.ncbi.nlm.nih.gov/Omim/searchomim.html. Type “aortic stenosis” (or synonyms) into the search box, and click “Submit Search.” If too many results appear, you can narrow the search by adding the word “clinical.” Each report will have additional links to related research and databases. In particular, the option “Database Links” will search across technical databases that offer an abundance of information. The following is an example of the results you can obtain from the OMIM for aortic stenosis: •

Search by keywords at http://www.nlm.nih.gov/mesh/jablonski/syndrome_db.html. The Genome Database24 Established at Johns Hopkins University in Baltimore, Maryland in 1990, the Genome Database (GDB) is the official central repository for genomic mapping data resulting from the Human Genome Initiative. In the spring of 1999, the Bioinformatics Supercomputing Centre (BiSC) at the Hospital for Sick Children in Toronto, Ontario assumed the management of GDB. The Human Genome Initiative is a worldwide research effort focusing on structural analysis of human DNA to determine the location and sequence of the estimated 100,000 human genes. In support of this project, GDB stores and curates data generated by researchers worldwide who are engaged in the mapping effort of the Human Genome Project (HGP). GDB’s mission is to provide scientists with an encyclopedia of the human genome which is continually revised and updated to reflect the current state of scientific knowledge. Although GDB has historically focused on gene mapping, its focus will broaden as the Genome Project moves from mapping to sequence, and finally, to functional analysis. To access the GDB, simply go to the following hyperlink: http://www.gdb.org/. Search “All Biological Data” by “Keyword.” Type “aortic stenosis” (or synonyms) into the search box, and review the results. If more than one word is used in the search box, then separate each one with the word “and” or “or” (using “or” might be useful when using synonyms).

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 aortic stenosis 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 aortic stenosis. 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 aortic stenosis. 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 “aortic stenosis”:

National Heart, Lung, and Blood Institute http://www.nhlbi.nih.gov/ Society of Thoracic Surgeons http://www.sts.org/section/stspatientinfo/ 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 aortic stenosis. 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.

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.25
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

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.
