XENOBIOTICS AND NEURODEVELOPMENTAL ABNORMALITIES Release Date: November 25, 1998 RFA: ES-99-002 P.T. National Institute of Environmental Health Sciences Letter of Intent Receipt Date: January 20, 1999 Application Receipt Date: February 10, 1999 PURPOSE The National Institute of Environmental Health Sciences (NIEHS) supports research to define the role of environmental agents in alterations of normal cellular and physiologic processes leading to human disease. The vulnerability of the developing organism to environmental factors has become a major concern of the public health community and the environmentally active general public. The developing nervous system is central to much of this concern. Therefore, the identification and understanding of the mechanisms responsible for the increased sensitivity of the developing nervous system to environmental insult is the focus of this initiative. HEALTHY PEOPLE 2000 The Public Health Service (PHS) is committed to achieving the health promotion and disease prevention objectives of "Healthy People 2000," a PHS-led national activity for setting priority areas. This RFA, Xenobiotics and Neurodevelopmental Abnormalities, is related to the priority area of environmental health. Potential applicants may obtain a copy of "Healthy People 2000: (Full Report: Stock no. 017-001-00474-0 or Summary Report: Stock No. 017- 001-00473-1) through the Superintendent of Documents, Government Printing Office, Washington, DC 20402-9325 (telephone: (202) 512-1800). ELIGIBILITY REQUIREMENTS Applications may be submitted by domestic, for-profit and non-profit organizations, public and private, such as universities, colleges, hospitals, laboratories, units of State or local governments and eligible agencies of the Federal government. Foreign institutions and organizations are not eligible. Applications from minority individuals and women are encouraged. Submission of an application precludes concurrent submission of a regular research project grant application (R01) containing the same research proposal. In addition, small grant research support may not be used to supplement research projects currently supported by Federal or non-Federal funds or to provide interim support for projects under review by the Public Health Service. MECHANISM OF SUPPORT This RFA will use the National Institutes of Health (NIH) Small Grants Program (R03) awards. Responsibility for the planning, direction, and execution of the proposed project will be solely that of the applicant. The requested costs and project period will be $50,000 (direct cost) per year for a maximum of two years. Small grants are not renewable but may be extended at the discretion of the applicant organization. FUNDS AVAILABLE The total estimated funds available for this small grants program is $750,000 which will support approximately ten awards. This level of support is dependent on the receipt of sufficient number of applications of high scientific merit. Although this program is provided for within the financial plans of the NIEHS, awards pursuant to this RFA are contingent upon the availability of funds for this purpose. RESEARCH OBJECTIVES Background NIEHS has had a longstanding commitment to assessing chemicals for potential developmental effects and for effects on the nervous system. Much of the previous research on the developing nervous system has focused on behavioral alterations with limited effort directed toward the underlying biological processes critical to the formation of the nervous system and their role in the altered behavior. This Request for Applications is designed specifically to encourage exploration of the possible underlying cellular mechanisms associated with the formation of the nervous system and the part they play in determining alterations due to exposure to environmental agents. These processes may include: the division of neural and glia precursors, the interaction of the cell with its immediate environment by surface receptors or cell adhesion molecules, the regulation of cytoskeletal or cell surface process that control migration of neural cells, and/or the cell-cell interactions that underlie synaptogenesis. In addition, signaling molecules including growth factors, neurotransmitters, cell adhesion molecules and components of the extracellular matrix influence the migration, differentiation and survival of neurons and neuronal precursors. Neurotoxicants that interfere with any of these processes and/or molecules during a critical window in development would be expected to have serious effects on the developing organism. These defects may be immediately obvious as gross malformations, but they may also be manifest as more subtle defects that may have serious consequences as indicated by behavioral disturbances. In order for NIEHS to successfully carry out its mission of reducing the burden of neuronal dysfunctions due to early perturbations from agents in the environment, it is imperative to have information on the role of environmental factors on a wide variety of critical mechanisms during nervous system development. Currently, there is good evidence from research on epidemiology and cell biology for the role of lead in developmental impairment while the role of pesticides and polychlorobiphenyls are far less well understood. Studies of other agents have been limited possibly because most developmental biologists and neurotoxicologists have not been encouraged to explore the effect on developmental processes with these neurotoxic agents. The purpose of this initiative is to foster such multidisciplinary research efforts using state-of- the-art knowledge and techniques in cell biology and molecular biology to develop mechanistically-based methods and models for developmental neurotoxicology. The initiative is also intended to stimulate the development of pilot or feasibility studies on critical target sites and biological processes susceptible to environmental manipulation. Research Goals The small grants mechanism is seen as a way of encouraging both new and established investigators to explore new areas of environmental neurodevelopmental research that, while being of high risk, have the potential of advancing the field. Consequently, neurotoxicants such as lead or methylmercury for which the link between exposure and developmental dysfunction have been established and for which a body of research looking at molecular mechanisms exist, would not be considered in compliance with this initiative. Moreover, if sufficient preliminary data are available to support an investigator-initiated proposal, such an application would not be considered in compliance. By encouraging small grants to obtain preliminary data, it is the objective of NIEHS to support investigators in both developmental neurobiology and neurotoxicology to collaborate in examining the susceptibility of the developing nervous system to environmental exposure. Preliminary data are essential to identify critical biological processes underlying developmental neurotoxicity. Once this information is developed, studies on the site, mode, and mechanism of action of the environmental influences can then be generated and prevention and intervention strategies can be developed. It is anticipated that the preliminary information from these pilot studies will provide the linkage of environmental exposures (under physiologically relevant conditions of both timing and dose) during development to subsequent neurological disorders and will lead to the development of hypothesis-based research to establish the cause and effect relationship in such disorders. Research is encouraged in but not limited to the following areas: o The linkage of xenobiotics with basic developmental processes such as cell division, differentiation, cell adhesion molecules, cell-cell interactions, growth factors, receptor activation, signal transduction activation, or apoptosis leading to functional abnormalities. o The development and use of animal and human model systems including immortalized cell lines, primary culture, and whole animals including transgenic animals and specific mutants to identify and characterize the developmental defect that occurs in response to a neurotoxicant. o Multidisciplinary studies that relate specific changes induced by xenobiotics in neurochemical, neuroanatomical, neurophysiological and/or neurobehavioral measurements during development with behavioral deficits. o The identification and validation of specific developmental milestones or critical developmental processes (in a regional and temporal fashion) which could be used as biomarkers of toxicity. o Studies to further refine and advance behavioral methodologies, particularly the development of behavioral test methods with direct cross--species applicability, including tests for ontogenic development of various cognitive functions, and for the determination of the sensitivity of neuropsychological tests and their modulation by motivational influences. o To determine the role of compensation, redundancy and latency in the response of the developing nervous system to toxic perturbation. INCLUSION OF WOMEN AND MINORITIES IN RESEARCH INVOLVING HUMAN SUBJECTS It is the policy of the NIH that women and members of minority groups and their subpopulations must be included in all NIH supported biomedical and behavioral research projects involving human subjects, unless a clear and compelling rationale and justification is provided that inclusion is inappropriate with respect to the health of the subjects or the purpose of the research. This policy results from the NIH Revitalization Act of 1993 (Section 492B of Public Law 103-43. All investigators proposing research involving human subjects should read the "NIH Guidelines for Inclusion of Women and Minorities as Subjects in Clinical Research," which was published in the Federal Register of March 28, 1994 (FR 59 14508-14513) and in the NIH Guide for Grants and Contracts, Vol. 23, No. 11, March 18, 1994, available on the web at: https://grants.nih.gov/grants/guide/notice-files/not94-105.html. INCLUSION OF CHILDREN AS PARTICIPANTS IN RESEARCH INVOLVING HUMAN SUBJECTS It is the policy of NIH that children (i.e., individuals under the age of 21) must be included in all human subjects research, conducted or supported by the NIH, unless there are scientific and ethical reasons not to include them. This policy applies to all initial (Type 1) applications submitted for receipt dates after October 1, 1998. All investigators proposing research involving human subjects should read the "NIH Policy and Guidelines" on the Inclusion of Children as Participants in Research Involving Human Subjects that was published in the NIH Guide for Grants and Contracts, March 6, 1998, and is available at the following URL address: https://grants.nih.gov/grants/guide/notice-files/not98-024.html. Investigators also may obtain copies of these policies from the program staff listed under INQUIRIES. Program staff may also provide additional relevant information concerning the policy. LETTER OF INTENT Prospective applicants are asked to submit, by January 20, 1999, a letter of intent that includes a descriptive title of the proposed research, the name, address, and telephone number of the Principal Investigator, the identities of other key personnel and participating institutions, and the number and title of the RFA in response to which the application may be submitted. Although a letter of intent is not required, is not binding, and does not enter into the review of subsequent application, the information that it contains is helpful in planning for the review of applications. It allows NIEHS staff to estimate the potential review work load and to avoid conflict of interest in the review. The letter of intent is to be sent to: Ethel B. Jackson, D.D.S.

Therefore, investigators who are ready to submit an R01 application (i.e., have sufficient preliminary data, etc.) are encouraged to do so as their applications will receive special consideration for funding. Also, encouraged are individual postdoctoral fellowships in this area. o Appendix materials may not be used to circumvent the page limitations The RFA label available in the PHS 398 (rev. 4/98) application form must be affixed to the bottom of the face page of the application. Failure to use this label could result in delayed processing of the application such that it may not reach the review committee in time for review. In addition, the RFA title and number must be typed on line 2 of the face page of the application form and the YES box must be marked. Submit a signed, typewritten original of the application, including the checklist, and three signed, clear, and single-sided photocopies in one package to: CENTER FOR SCIENTIFIC REVIEW NATIONAL INSTITUTES OF HEALTH 6701 ROCKLEDGE DRIVE, ROOM 1040 - MSC 7710 BETHESDA, MD 20892-7710 BETHESDA, MD 20817 (for express/courier service) At the time of submission, two additional copies of the application must be sent to: Ethel Jackson, D.D.S. Division of Extramural Research and Training National Institute of Environmental Health Sciences P.O. Box 12233, EC-24 111 T.W. Alexander Drive, Room 3457, East Campus (for express/courier service) Research Triangle Park, NC 27709-2233 Telephone: (919) 541-7846 FAX: (919) 541-2503 Email: jackson4@niehs.nih.gov Applications must be received by February 10, 1999. If an application is received after that date, it will be returned to the applicant without review. The Center for Scientific Review (CSR) will not accept any application in response to this RFA that is essentially the same as one currently pending initial review, unless the applicant withdraws the pending application. The CSR will not accept any application that is essentially the same as one already reviewed. This does not preclude the submission of substantial revisions of applications already reviewed, but such applications must include an introduction addressing the previous critique. REVIEW CONSIDERATIONS Upon receipt, applications will be reviewed for completeness by the CSR and responsiveness by the NIEHS. Incomplete and/or non-responsive applications will be returned to the applicant without further consideration. Applications that are complete and responsive to the RFA will be evaluated for scientific and technical merit by an appropriate peer review group convened by the NIEHS in accordance with the review criteria stated below. As part of the initial merit review, a process will be used by the initial review group in which applications receive a written critique and undergo a process in which only those applications deemed to have the highest scientific merit, generally the top half of the applications under review, will be discussed, assigned a priority score, and receive a second level review by the NIEHS National Advisory Environmental Health Council or Board. Review Criteria The goals of NIH-supported research are to advance our understanding of biological systems, improve the control of disease, and enhance health. In the written comments reviewers will be asked to discuss the following aspects of the application in order to judge the likelihood that the proposed research will have a substantial impact on the pursuit of these goals. Each of these criteria will be addressed and considered in assigning the overall score, weighting them as appropriate for each application. Note that the application does not need to be strong in all categories to be judged likely to have major scientific impact and thus deserve a high priority score. For example, an investigator may propose to carry out important work that by its nature is not innovative but is essential to move a field forward. (1) Significance: Does this study address an important problem? If the aims of the application are achieved, how will scientific knowledge be advanced? What will be the effect of these studies on the concepts or methods that drive this field? (2) Approach: Are the conceptual framework, design, methods, and analyses adequately developed, well-integrated, and appropriate to the aims of the project? Does the applicant acknowledge potential problem areas and consider alternative tactics? (3) Innovation: Does the project employ novel concepts, approaches or method? Are the aims original and innovative? Does the project challenge existing paradigms or develop new methodologies or technologies? (4) Investigator: Is the investigator appropriately trained and well suited to carry out this work? Is the work proposed appropriate to the experience level of the principal investigator and other researchers (if any)? (5) Environment: Does the scientific environment in which the work will be done contribute to the probability of success? Do the proposed experiments take advantage of unique features of the scientific environment or employ useful collaborative arrangements? Is there evidence of institutional support? In addition to the above criteria, in accordance with NIH policy, all applications will also be reviewed with respect to the following: o The adequacy of plans to include both genders, minorities and their subgroups, and children as appropriate for the scientific goals of the research. Plans for the recruitment and retention of subjects will also be evaluated. o The reasonableness of the proposed budget and duration in relation to the proposed research. o The adequacy of the proposed protection for humans, animals or the environment, to the extent they may be adversely affected by the project proposed in the application. The initial review group will also examine the provisions for the protection of human subjects and the safety of the research environment.
