RFA: 89-HD-08 GENETICS AND BIOCHEMISTRY OF CELL FATE DETERMINATION IN DEVELOPMENT; CYTOPLASMIC DETERMINANTS, CELLULAR INDUCTION AND GENOMIC IMPRINTING P.T. 34; K.W. 1002019, 1003002, 1002004, 1002059 NATIONAL INSTITUTE OF CHILD HEALTH AND HUMAN DEVELOPMENT Application Receipt Date: February 8, 1990 The Genetics and Teratology Branch (GTB) of the Center for Research for Mothers and Children (CRMC) of the National Institute of Child Health and Human Development (NICHD) invites research grant applications for studies on the genetics and biochemistry of cell fate determina- tion in development. By issuing this request for applications (RFA), the Branch is encouraging investi- gators' interest in a research emphasis area important to the Institute's mission. BACKGROUND The phenotypic fate of an individual cell within a developing organism can be determined quite early in its developmental program. While the ultimate phenotypic fate of any given cell results from the integration of several different biological processes, including cell migration, cell interaction, and tissue specific gene expression, certain early developmental events have enormous influence on the developmental potential of that cell. Questions concerning the nature of such early developmental events have been, and continue to be, one of the central unresolved issues in developmental biology. Experiments that are now classic have demonstrated that material contained in the egg prior to fertilization can have a direct impact on developmental outcome. Studies that have reoriented, removed, or transplanted portions of cytoplasm have demonstrated that determinants exist within that cytoplasm that can influence the phenotypic fate of cells within the developing organism. Adjacent cells have been shown to influence the fate of their immediate neighbors by inducing particular responses. More recent experiments have demonstrated that the ability of a particular gene to express at all, and have any impact on cell fate, can be "preprogrammed" in the parental generation. Thus, the physical orientation of the embryo, the determination of germ layers, or the determination of specific cell phenotypes can be directed by one or more of these biological processes. Clearly, the failure of any of these processes to operate normally could lead to developmental anomalies. Therefore, NICHD encourages studies on the genetic and biochemical basis of cell fate determination which could lead to a better understanding of normal development and to the prevention of congenital malformation in the future. The purpose of this RFA is to stimulate and encourage research directed at defining the underlying genetic basis, biochemical nature, and molecular mode of action of the processes that can influence cell fate, including cytoplasmic determinants, induction, and genetic imprint- ing. While our major interest rests in how such processes operate during mammalian development, other experimental model systems that can contribute to our understanding of the fundamental principles that apply to human development are strongly encouraged. The National Institute of General Medical Sciences (NIGMS) also supports research leading to an understanding of fundamental principles underlying genetics and cell biology, especially in model systems. Therefore, a secondary assignment to NIGMS for applications responsive to this RFA might be appropriate. It is realized that additional descriptive work is needed to expand the field. However, investigators are encouraged to suggest approaches that characterize the biological nature of these processes at the molecular level, including the identification of the molecules involved, their genetic regulation, their functional roles, and their mode of action. This initiative has important implications for both basic science and clinical studies. The information expected from these investigations will further our understanding of the specific molecules involved in establishing cell fate, how they are regulated, and how they function. In addition, underlying principles that direct normal patterns of growth, differentiation and morphogenesis and against which aberrations of these processes can be understood will be further defined. In a clinical context, these studies provide the basis for an improved understanding of the possible causes of birth defects and other developmental abnormalities that lead to early embryonic wastage and spontaneous abortion. RESEARCH GOALS The primary goal of this RFA is to support a group of projects that are devoted to the investigation of the genetics and biochemistry of cell fate determination during development. It is expected that the latest molecular biological and molecular genetic technologies will be employed, including the generation of appropriate reagents and either chimeric or transgenic animals, if appropriate. Particular program interest includes, but is not limited to, such issues as: o Identification and molecular characterization of specific cytoplasmic determinants o Identification, characterization, and mode of action of molecules responsible for the localization of determinants within the cytoplasm Such molecules could include architectural or anchorage components that are responsible for maintaining localized concentrations of specific determinants. o Elucidation of mechanisms that maintain functional gradients of cytoplasmic determinants either by regulating absolute levels of the molecules or their functional expression o Elucidation of possible cascade events that together are responsible for the localized expression of cell fate-determining molecules o Identification and characterization of endogenous molecules with specific inductive capabilities o Investigation of the genetic regulation of either cytoplasmic or inductive determinants Such studies could include classic studies involving the genetic transmission of such molecules or the analysis of mutants with abnormal expression. In addition, molecular genetic approaches could be employed, including the isolation of specific genes and the identification of sequences responsible for localized expression. o Investigation of mechanisms responsible for the genetic imprinting of certain genes MECHANISM OF SUPPORT Applications in response to this RFA will be funded through the traditional individual research award program of NICHD (R01 and R29). This announcement is for a single competition with the deadline for receipt of applications February 8, 1990. The earliest possible start date for grants would be December 1, 1990. It is anticipated that four (4) grants will be awarded under this program, contingent upon receipt of a sufficient number of meritorious applications and the availability of funds. REVIEW PROCEDURES AND CRITERIA Applications will be reviewed by NICHD staff for respon- siveness to the RFA. Applications judged to be nonresponsive will be returned. The applicant may resubmit the application and have it assigned for review in the same manner as unsolicited grant applica- tions. An application will be considered nonresponsive to this RFA if it is identical to one already submitted to the NIH for review, unless the previous application is withdrawn. Responsive applications may be subjected to a triage by a peer-review group to determine their scientific merit relative to the other applications received in response to this RFA. NIH will withdraw from competition those applications judged to be noncompetitive and notify the applicant and institutional business official. Those applications judged to be competitive will be further evaluated for scientific/technical merit by a review group convened during June 1990 solely for this purpose by the Scientific Review Program, NICHD. Criteria for the initial review include the significance and originality of research goals and approaches; the feasibility of research and adequacy of the experimental design; the research experience and competence of the investigator(s) to conduct the proposed work; the adequacy of investiga- tor(s) effort devoted to the project; and the appropriateness of the project duration and cost relative to the work proposed. Following review by the Initial Review Group, applications will be evaluated by the Institutes' Advisory Council for program relevance and policy issues before awards for meritorious proposals are made.

RFA AVAILABLE: 90-HL-4-H SPECIALIZED CENTERS OF RESEARCH (SCOR) IN ARTERIOSCLEROSIS P.T. 04; K.W. 0715040, 0710030, 0755030, 0745027 National Heart, Lung, and Blood Institute Application Receipt Date: December 3, 1990 INTRODUCTION The Division of Heart and Vascular Diseases (DHVD) of the National Heart, Lung, and Blood, Institute (NHLBI) invites new and renewal grant applications to enter into a single open competition for Specialized Centers of Research in Arteriosclerosis (SCOR/A). In keeping with the criteria for Centers, the solicitation requires all applicants to propose both basic and clinical research. The goal of the program is to advance understanding of the causes and mechanisms of atherogenesis and through this knowledge improve prevention, diagnosis and treatment in patients afflicted with this disease. The aim of this request for applications is to solicit and support interdisciplinary programs focusing on particularly promising areas of investigation in arteriosclerosis research. The solicitation is designed to further diversify the SCOR/A program and to encourage new applicants. Arteriosclerosis is a family of pathological processes and is strongly influenced by abnormalities of lipid and lipoprotein metabolism. However, lipoprotein metabolism is only part of the disordered vascular biology that results in atherosclerosis. Other important elements in the pathogenesis and natural history of arteriosclerosis interact with or exert effects independent of lipid changes. These include the roles the arterial wall cells play in response to lipids; the coordination of vascular cellular events following stimulation to yield plaques of various types; the cellular and molecular biology of relevant participating cells and their regulatory systems; vascular developmental biology and vascular and metabolic responses to atherogenic stimuli; the roles of the thrombotic process in all aspects of atherogenesis; and the healing or regression of atherogenesis. The NHLBI wishes to encourage efforts to use molecular genetic approaches to identify and characterize those genes that may interact with or are independent of genes related to lipid metabolism that may play a major role in the causation of atherosclerosis. BACKGROUND Arteriosclerosis is a complicated disease with an incompletely understood etiology. An interdisciplinary approach to this disorder is required, and the SCOR/A program has provided a focus for this particular approach to understanding the disorder. The SCOR/A has been and remains a particularly responsive and productive mechanism for meeting the needs of arteriosclerosis research. It was initiated in 1971 as a special program mechanism to extend the "state-of-the art" of research on arteriosclerosis and to apply research findings to disease prevention and control. The SCOR/A program has pioneered new directions of research, enlisted skills and disciplines not previously associated with research on arteriosclerosis and attracted able investigators to the field. The Centers have addressed arteriosclerosis as a multifactorial disease and promoted multidisciplinary research on the relationships of hyperlipidemia, hypertension, thrombosis, diabetes, smoking, and other risk factors and diseases to the etiology and pathogenesis of arteriosclerosis. The Centers have attained preeminence in research on lipid and lipoprotein metabolism, and in studies of the structure and function of lipoproteins and apoproteins. The program has established extensive non- human primate resources to focus on lesion progression/regression. Other active research areas include nutrition, lipid and lipoprotein metabolism, biobehavioral research, and studies on the relationship of hemodynamics to atherogenesis. The SCOR/A fostered research on pediatric arteriosclerosis, and initiated demonstration and education, and behavioral and psychosocial research in the area of risk factor reduction. The program also pioneered affiliations with biomedical engineering laboratories to develop computer-assisted x-ray processing technology and non- invasive instrumentation for the detection and assessment of lesion progression and regression. Many of the studies pioneered by SCOR/A are currently supported by other program mechanisms in the Institute. An unusual attribute of the SCOR/A program has been the ability to undertake studies which are of long duration. Such studies have extended over several of the five year project periods of the Centers and are not generally supported by other mechanisms of grant support. These have included a study in non-human primates of lesion regression in advanced atherosclerosis, the breeding of animal models for selected risk factor traits, and a multiple drug-diet trial to determine whether marked reductions of serum lipid levels in individuals with familial hypercholesterolemia will result in the regression of arterial lesions. A further special and important attribute of the SCOR/A is that the Centers function collectively as a program. Several of them participate in collaborative studies with other SCOR/A Centers. There is an annual 2 day SCOR/A scientific meeting attended by 80 to 100 investigators and an annual joint Institute-SCOR Directors meeting for planning purposes. NHLBI also fosters scientific exchange by providing to the investigators a compilation of the annual SCOR progress reports. These activities, together with collaboration outside of the SCOR/A, have extended the research capabilities of the individual Centers. The current SCOR/A Program consists of six Centers and one National Research and Demonstration Center (NRDC) representing the fourth generation of the SCOR/A (1986-1991). In addition to conducting the research described above, the current program also has included the cellular biology of atherogenesis; studies on the role of the endothelial cell in relation to procoagulant and anticoagulant activities; lipoprotein modification and lipoprotein-associated prostaglandin synthesis; studies on the mechanisms of macrophage vascular wall infiltration and lipid accumulation; ultrastructural studies of cells; and the assembly and biosynthesis of lipoproteins and matrix. New studies have also been undertaken to define genetic markers and the role of non-traditional risk factors for arteriosclerosis. There remain numerous research opportunities in arteriosclerosis, and the comprehensive and multidisciplinary nature of the SCOR/A program is well suited for their exploitation. OBJECTIVES AND SCOPE Anticipating the most critical areas of research in arteriosclerosis during the 1990's that might benefit from SCOR support, more emphasis should be brought to bear on certain problems than is presently the case in the SCOR/A program. Also, since clinical investigation is important to research in arteriosclerosis, the program would benefit from an increase in such activity. The multidisciplinary collaborative atmosphere of a SCOR is suited to provide the impetus to translate basic studies into clinically useful diagnostic and therapeutic tools. An essential element in a SCOR program in arteriosclerosis is the integration of fundamental studies of pathophysiologic mechanisms with studies in patients. The program should, therefore, provide an opportunity to integrate studies at various levels, e.g. molecular, cellular, structural and functional with abnormalities observed clinically. Additionally, the SCOR program should offer an opportunity to investigate mechanisms involved in the sequelae to a clinical intervention and to perform studies designed to provide a rationale for the choice of pharmacologic agents or dietary regimens. In the past the SCOR/A have played a prominent role in fostering research in demonstration and education and behavioral modification, beginning with the Stanford Three Community Study and continuing with similar activities in National Research and Demonstration Centers. In the meantime NHLBI has developed a substantial program of demonstration and education research, a Behavioral Medicine Branch with a regular grant program, and other activities such as the National Cholesterol and the National High Blood Pressure Education Programs. There now is no need for such activities in the SCOR/A program, so they will neither be solicited nor accepted. AREAS OF OPPORTUNITY The past decade has seen astonishing progress in molecular and cellular biology including molecular genetics and gene manipulation. These technologies could find wide application to areas of interest in arteriosclerosis, such as systemic and local lipid metabolism; thrombotic processes; the biology, pathobiology and pharmacology of the vessel wall; and the concepts of resistance and susceptibility to lesion development. Moreover, there have been great gains in characterizing and utilizing comparative models of atherogenesis and in the ability to study cell-cell communication, differentiation and interaction. The application of these technologies to cells, tissues and organs and especially to plaque building and regression can be exploited by the SCOR/A. This solicitation is designed to emphasize research that is directed toward fundamental mechanisms in atherogenesis and new approaches to disease prevention, diagnosis and treatment. A mutually supportive interaction between basic scientists and clinical investigators will be essential. The individual projects should be correlative or complementary in terms of the topic or topics chosen by the applicant. Each SCOR must represent a multidisciplinary approach to both clinical and laboratory research focused on particular problems within the field of arteriosclerosis. Although research programs will vary with local talent, interest, and resources, each SCOR should have a central theme to which all individual projects relate and which serves as an integrating force. Emphasis in proposed projects should be on the development of innovative approaches, the elaboration of new and significant hypotheses, and the generation of novel strategies. Collaborative research between different institutions may be proposed when appropriate. New applicants are strongly encouraged to participate in this competition. The following brief discussion is intended to offer a few examples of research sought and to emphasize the importance of employing a wide spectrum of basic and clinical approaches in the SCOR environment to addressing these important problems. These areas have been identified by members of the arteriosclerosis research community including Advisory Committee members and Institute Staff; however, they are not all-inclusive. Investigators are strongly urged to consider other relevant projects and approaches not mentioned below. o Lipid interactions with the vessel wall The basic mechanisms involved in the initiation of the atherosclerotic lesion as well as those events that sustain and lead to progression are not very well understood. Lipoprotein metabolism by the arterial wall, and other tissues in vivo and ex vivo are areas that need further investigation. Of importance are measurements to quantify the kinetics of lipoprotein uptake, residence time, and rates of degradation with special emphasis on the contribution of individual resident cell types. Quantitative measurements of these early events could provide tools that might be used to test strategies and therapeutic modalities that could be used to inhibit or reverse the early lesions. The use of molecular biological approaches coupled with basic studies of molecular genetics/gene regulation and their possible use as a cross-over to clinical investigations would be of great interest. o Pathogenesis of plaques Investigation of basic mechanisms of plaque formation, and elements involved therein, is encouraged. This includes, but is not limited to: vascular biology and metabolism involving smooth muscle cells, endothelial cells, and the extracellular matrix; the rheology of blood flow; elements of inflammation; leukocytes, lymphocytes and other blood components; and macrophage biology. Pharmacological probes may prove useful to study mechanisms of atherogenesis. o Receptor physiology Hormones and other ligands are known to regulate their own receptors, but it has only recently been recognized that receptors can determine the concentrations of their own ligand. The most clear-cut example occurs in the LDL receptor system. Increasing the number of receptors will decrease the level of the circulating ligand. Novel approaches to effect changes in receptor levels are highly desirable. The development of transgenic animal models and gene transfer studies may prove useful tools to study receptor biochemistry and physiology. o Cellular and metabolic responses to challenge An area that will benefit from further attention is the genetic basis of factors that determine sensitivity and resistance to atherosclerosis as well as differences in the response to dietary challenge. Emphasis on the diversity of responses could be investigated in mechanistic studies of nutritional challenges that could include oxidized sterols and fatty acids of varied chain lengths and degrees of saturation. Studies of age- related phenomena are also needed. o Gene regulation Apolipoprotein genetic variation plays a major role in determining human genetic susceptibility to atherosclerosis. In the last few years, cDNA and genomic clones have been derived for the apolipoproteins. The apolipoprotein genes have been mapped in the human genome and mutations in the human genes have been identified at both the amino acid and DNA levels. Some of these mutations have profound effects on lipoprotein metabolism and are associated with premature atherosclerosis. Yet, it is not well determined how their expression is regulated and whether other regulatory factors exist that might have clinical significance. o Genetic studies of premature atherosclerosis The goal of this research is to characterize the genes and their products that contribute significantly to the development of premature atherosclerosis. Several studies have indicated that familial aggregation for coronary heart disease (CHD) may be associated with genetic predispositions not adequately explained by the traditional risk factors. In some patients, CHD is the result of a single gene defect such as in familial hypercholesterolemia. However, most CHD fits best into a multifactorial category where the interaction of multiple genes with multiple environmental factors produces the familial aggregation. The number of genes involved may be large for a complex disorder such as CHD, in which plasma lipoproteins, the coagulation system, the cellular elements and other components of the blood and arterial wall all play a part. A primary objective of this line of research would be to undertake segregation analyses and genetic linkage studies in families with premature atherosclerosis, employing classical genetic methodology and molecular biologic techniques. Additional objectives would be to: phenotype individual family members for selected characteristics; develop additional phenotypic markers according to the interests of the investigator; and establish a collection of DNA obtained from each phenotyped family member, that will be made available to other SCOR investigators and ultimately to the scientific community. Arrangements for collaborative efforts among institutions are considered appropriate to satisfy the objectives of this line of research. o Vascular developmental biology Research to discover fundamental mechanisms of developmental biology underlying atherogenesis is of particular interest. This would include investigations of the relationship of cell proliferation to differentiation at the molecular level and the formation of the vessel wall during embryogenesis. Several current issues in vascular developmental biology merit particular consideration. These include factors controlling endothelial and smooth muscle cell growth during development; mechanisms controlling differentiation of the cells of the vessel wall from primitive mesenchyme; factors controlling genetic diversity of the cells of the vascular wall; the role of endothelial cells in smooth muscle differentiation and modulation; the formation of vascular intimal cells and their relationship to medial smooth muscle cells and localization of atherosclerosis; and the role of developmental mechanisms in the ontogeny of the hypertensive vasculature. o Atherogenesis and thrombotic processes Several issues implicating the hemostatic system in atherogenesis merit consideration. These include possible links between plasma lipoproteins and the coagulation factors; studies of the relative contributions of lipid and non-lipid atherogenic and thrombotic factors in selected lipid disorders in vivo; interactions of coagulation factors with lipoprotein subspecies, possibly including their effect on the function of the endothelial cells, blood cells and platelets; mechanisms regulating the interaction of blood components with the vascular endothelium, including the roles of peptide regulatory factors and eicosanoids in thrombosis and atherogenesis; factors regulating endothelial functions such as macromolecular transport and abnormal permeability; and mechanisms controlling the arterial endothelial thrombo-resistance processes. The foregoing account is intended to provide examples of research that are appropriate for the SCOR mechanism. Applicants should design programs based on their own knowledge of the fields, their perceptions of research needs, and the feasibility of research in those areas. While lipid phenomena continue to be central, the examples cited are in keeping with concepts and technologies of research for the next decade. However, the intention to emphasize research exploiting the use of molecular biological approaches, molecular genetics/gene regulation, vascular biology and metabolism, physiology of the response to challenge and use of pharmacological probes to study mechanisms of atherogenesis, will require efforts by investigators not previously associated with research on arteriosclerosis and offers the opportunity for the establishment of new centers. ELIGIBILITY CRITERIA In addition to the standard criteria defining eligibility for Public Health Service grants, the applicant organization must be, or must be associated with, a major medical institution. All elements of a program must include, and be subjected to, stringent and critical evaluative procedures. Women and minority individuals should be included in the study population, otherwise a clear rationale for their exclusion must be provided in the application. Universities and medical schools, hospitals and public or private research institutions, alone or in combination, with appropriate research and clinical capabilities to meet the objectives of this SCOR program are encouraged to respond to this solicitation. EXCLUSIONS The fourth competition for the SCOR/A program, announced in 1984, provided the opportunity for the SCORs to extend the results of basic and clinical research to the community by integrating demonstration and education research and competing as National Research and Demonstration Centers (NRDC). This option will NOT be available for the present competition. Investigators interested in pursuing demonstration and education research in the topic area of the SCOR/A are requested to contact NHLBI Staff to discuss options. No support will be provided under the SCOR funding mechanism for largely epidemiological programs or programs containing exclusively clinical or exclusively basic studies. While the development of new instrumentation may be part of the SCOR, support for development alone will not be provided. Institute staff should be consulted if an applicant plans to request funds to purchase and install expensive new equipment. Applicants should be aware that applications for supplemental funds will be accepted only under unusual and well defined circumstances. For example, NHLBI may provide supplements to centers to continue a project not funded for the entire project period. NHLBI staff should be consulted prior to submission of an application. Supplemental grants for these purposes will not be awarded for the first 18 months or the last 12 months of a total project period. MECHANISM OF SUPPORT The support mechanism will be the research grant-in-aid (P50) for a period of five years commencing December 1, 1991. However, it will differ from other research grants in that there will be required communication between SCORs, usually in the setting of a biennial combined meeting of SCOR participants. Therefore, in preparing the budget, applicants should request travel funds for this purpose in fiscal years 1992, 1994, and 1996 of the budget. Applicants are expected to furnish their own estimates of the time required to achieve specific objectives of the proposed work, a schedule for completion of the work, and an outline of the segments into which the proposed program can be logically divided. The SCOR will plan, direct, and execute its own research program, but any substantial modification in the scope or objectives that may be approved for funding must be mutually agreed upon by the SCOR Director and the NHLBI. Although this solicitation is included in the plans for Fiscal Year 1992, support of grants pursuant to this request for applications is contingent upon ultimate receipt of funds for this purpose. It is anticipated that approximately 10 SCORs will be funded under this RFA for a total annual cost (direct and indirect) of about $20 million. The level of funding of the individual SCORs will be influenced by the overall merit of proposals, the level of support recommended during the initial scientific review, and the amount of funds available to the Institute. Since a variety of approaches may be responsive to this solicitation, it is anticipated that there will be a range of costs among individual grants awarded. Applications for new SCOR grants may request up to $1.0 million direct costs in the 01 year with a maximum of 4 percent annual escalation thereafter. Competing renewal applications for SCOR grants may request up to $1.0 million direct costs or 10 percent increase in direct costs over the last noncompeting year, whichever is greater, in the first year of renewal, with a maximum of 4 percent annual escalation thereafter. Applications which exceed these limits will be returned. Requests for special equipment which cause the applications to exceed these limits, however, will be permitted and considered on an individual basis. CONTACT NHLBI STAFF IF YOU HAVE ANY QUESTIONS. REVIEW PROCEDURES AND CRITERIA SCOR/A applications will be reviewed and evaluated in a single national competition. The initial phase of peer review will be conducted by a group of predominantly non- federal consultants and may involve a site visit. A second level of review will be performed by the National Heart, Lung, and Blood Advisory Council. The applicant is not permitted to revise the application (no additions or deletions of projects, cores or studies) after submission to the Division of Research Grants. Projects and/or cores within a SCOR grant may not be modified or withdrawn during the review process. All projects and/or cores reviewed at a site visit, will be included in the site visit report when the application is evaluated by the Parent Review Committee and also in the summary statement, when it is considered by the Institute's Advisory Council. The major factors to be considered in the evaluation of applications include: The qualifications, experience and commitment of the SCOR Director and his/her ability to devote adequate time and effort to provide effective leadership; the scientific merit of each proposed project including the originality, feasibility of the approach, and the adequacy of the experimental design; the competence of the investigators to accomplish the proposed research goals, their commitment, and the time they will devote to the program; the integration of the interdisciplinary efforts into a coherent enterprise with adequate plans for interaction and communication of information and concepts among the collaborating investigators; the technical merit and justification of each core unit; the adequacy of facilities to perform the proposed research including the laboratory and clinical facilities, access to subjects, instrumentation, and data management systems when needed; the scientific and administrative structure of the program, including adequate internal and external arrangements and procedures for monitoring and evaluating the proposed research and for providing ongoing quality control and scientific review; the institutional commitment to the program and the appropriateness of the institutional resources and policies for the administration of a research program of the type proposed; and the appropriateness of the budget for the proposed program.
