PURPOSE OF THIS PA
The National Institute of Environmental Health Sciences (NIEHS) invites
applications to study environmental agents that cause cardiovascular
malformations (CVMs). The purposes of this Program Announcement (PA) are to
stimulate research to characterize environmental agents that cause alterations
in the development of the cardiovascular system and thereby lead to
cardiovascular malformations, and to investigate the cellular and molecular
mechanisms involved in the development of these malformations. The use of
mammalian and non-mammalian animal models, including transgenic and gene
knock-out animal models, and of state-of-the-art molecular biology techniques
such as genomics and proteomics is encouraged, as well as collaborations
between environmental health scientists and developmental biologists, to
develop research programs to address the high rate of cardiovascular
malformations.
RESEARCH OBJECTIVES
Background
Cardiovascular malformations (CVMs) are the most common type of birth defect
among live births in the US, occurring in approximately 0.8 percent of live
births. The most common types of CVMs include atrial or ventricular septal
defects, transposition of the great vessels, persistent truncus arteriosus,
teratology of Fallot, and coarctations. Despite the importance of these in
malformations, both in terms of human suffering and cost to the healthcare
system, the causes of most cases of CVMs are not known. Etiologic factors that
have been identified include genetics, maternal diseases, such as diabetes,
certain drugs, such as phenytoin and cocaine, and dietary factors, such as
folic acid deficiency, vitamin A excess, and copper deficiency. In addition,
certain environmental chemicals have been shown to be associated with cardiac
malformations. For instance, in one large epidemiological study of cardiac
malformations, the Baltimore-Washington Infant Study, exposure to such
environmental factors as paints, solvents and degreasers, and pesticides, were
associated with increased cardiac malformations. Epidemiological studies have
also reported CVM associations with air pollutants (ozone and carbon monoxide)
and trichloroethylene (TCE). In addition, environmental contaminants such as
TCE, bis-diamine, and dioxin have been shown to be cardiac teratogens in
animal studies. Despite the evidence for an environmental role in CVMs, the
list of environmental agents tested for teratogenic effects on the heart is
limited and relatively little research has been done on the cellular and
molecular basis of the teratogenic effects of environmental agents or on the
possible interactions between environmental exposures and other factors such
diet and genetics. Recent advances in genomic and molecular biology technology
and in the understanding of the development of the fetal heart, make this an
opportune time to initiate such studies.
General considerations:
o Chemicals to be studied can represent known teratogens, such as
trichloroethylene, or suspected teratogens, such as components of air
pollution. Studies of mixtures are also acceptable.
o In characterizing the actions of known or potential cardioteratogens,
dose-response curves should be determined, and the dose ranges should include
environmentally relevant doses.
o The use of state-of-the-art technologies, such as genomic and proteomic
technologies, is encouraged.
o Studies to determine interactions between environmental exposures and
genetics and/or nutritional factors are highly encouraged.
o The use of genetically altered model organisms, such as transgenic animals
and non-mammalian species, is encouraged.
o Proposals should take into consideration the metabolism of environmental
chemicals and the proximal metabolite to which the fetus is exposed.
o In general in vivo and organ cultures procedures should be used, except in
studies in which the ultimate CVM is known and in vitro experiments are
proposed to examine responses of specific fetal cell types, to determine
cellular and/or molecular mechanisms.
Specific areas of interest to NIEHS include, but are not limited to the
following:
o Characterization of new potential environmental cardioteratogens. This
characterization would include the types of CVMs induced, dose-response
evaluation, identification of specific windows of vulnerability to the agent,
and development of preliminary data for further mechanistic studies.
o Use of forward and reverse mutagenesis studies in model organisms to
determine the genes altered by specific cardiovascular developmental toxicants
and the relationship of the altered gene activity to dysmorphogenesis.
o Characterization of global gene expression profiles in the developing heart
of model organisms associated with the normal range of development and after a
developmentally toxic exposure. The relationship between the changes in gene
expression and the developmental lesion should be assessed.
o Use of genomic and/or proteomic profiling to determine how well data on
toxicant-induced malformations can be extrapolated across species.
o Identification and evaluation of specific signal transduction pathways and
the associated genetic regulatory circuits that might be sites of action of
developmental cardiovascular toxicants. The causal relationships between
exposure and the CVMs should be developed.
o Determination of the potential for interactions between exposures to
environmental agents and genetic susceptibility that increase the risk for
cardiovascular developmental toxicity.
Special Requirements
o This initiative focuses on mechanisms of development of CVMs. Therefore,
proposals dealing with human epidemiological or clinical studies will not be
considered as responsive. In some cases, use of human tissues in mechanistic
studies could be considered responsive.
o Proposals solely designed to screen a large number of agents will not be
considered responsive. Screening of members of specific classes of agents is
responsive as long as follow-up mechanistic studies of these agents are
included.
o Proposals should focus only on malformations of the heart and major vessels,
e.g., the aorta, vena cavae, pulmonary artery, and pulmonary vein.
o For this PA, diet will not be considered an environmental agent, and can
only be considered in the context of interactions with environmental agents
MECHANISM(S) OF SUPPORT
This PA will use the NIH R21 and R01 award mechanism(s). As an applicant, you
will be solely responsible for planning, directing, and executing the proposed
project. The total project period of an R21 proposal may not exceed two years,
and the total direct costs, including third party facilities and administrative
costs, may not exceed $100,000 per year.
The objective of the Exploratory/Developmental Grant (R21) mechanism is to
encourage applications for one-time grants to support innovative,
high-risk/high-impact research requiring preliminary testing or development,
exploration of the use of approaches and concepts new to a particular
substantive area, research and development of new technologies, techniques, or
methods, or initial research and development of data upon which significant
future research may be built. Applications will be considered as high impact
if they demonstrate the potential for ground-breaking, precedent-setting
significance, and high risk because they either lack sufficient preliminary
data to ensure their feasibility, or involve using a new model system or
technique. While this PA is intended to encourage innovation and high impact
research, and while minimal preliminary data are expected to be described in
the application, applications should clearly indicate that the proposed
research and/or development is scientifically sound, that the qualifications
of the investigators are appropriate, and that resources available to the
investigators are adequate. As the R21 grant project cannot be renewed, if
sufficient data are generated during the term of the award, investigators
could then apply for further funding through regular research grant, e.g., the
research project grant (R01) mechanism.
On the other hand, R01 grant applications should be grounded in more
established model systems and methodologies with which the investigators have
experience, as evidenced by preliminary data in the application and/or
publications in peer-reviewed literature, while at the same time being
innovative and moving the field forward.
This PA uses just-in-time concepts. It also uses the modular as well as the
non-modular budgeting formats (see
https://grants.nih.gov/grants/funding/modular/modular.htm
Specifically, if you are submitting an application with direct costs in each
year of $250,000 or less, use the modular format. Otherwise follow the
standard instructions for grant applications.
ELIGIBLE INSTITUTIONS
You may submit (an) application(s) if your institution has any of the
following characteristics:
o For-profit or non-profit organizations
o Public or private institutions, such as universities, colleges, hospitals,
and laboratories
o Units of State and local governments
o Eligible agencies of the Federal government
o Domestic or foreign
INDIVIDUALS ELIGIBLE TO BECOME PRINCIPAL INVESTIGATORS
Any individual with the skills, knowledge, and resources necessary to carry
out the proposed research is invited to work with their institution to develop
an application for support. Individuals from underrepresented racial and
ethnic groups as well as individuals with disabilities are always encouraged
to apply for NIH programs.

include a cover letter identifying the NIH staff member within one of NIH
institutes or centers who has agreed to accept assignment of the application.
Applicants requesting more than $500,000 must carry out the following steps:
1) Contact the NIEHS program staff at least six weeks before submitting the
application, i.e., as you are developing plans for the study,
2) Obtain agreement from the NIEHS staff that the NIEHS will accept your
application for consideration for award, and,
3) Identify, in a cover letter sent with the application, the staff member and
IC who agreed to accept assignment of the application.
This policy applies to all investigator-initiated new (type 1), competing
continuation (type 2), competing supplement, or any amended or revised version
of these grant application types. Additional information on this policy is
available in the NIH Guide for Grants and Contracts, October 19, 2001 at
https://grants.nih.gov/grants/guide/notice-files/NOT-OD-02-004.html.
SENDING AN APPLICATION TO THE NIH
Submit a signed, typewritten original of the application, including the
checklist, and five signed photocopies in one package to:
Center for Scientific Review
National Institutes of Health
6701 Rockledge Drive, Room 1040, MSC 7710
Bethesda, MD 20817 (for express/courier service)
APPLICATION PROCESSING
Applications must be received by or mailed on or before the receipt dates
described at https://grants.nih.gov/grants/funding/submissionschedule.htm
The CSR will not accept any application in response to this PA 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 a substantial revision of an application
already reviewed, but such application must include an Introduction addressing
the previous critique.
PEER REVIEW PROCESS
Applications submitted for this PA will be assigned on the basis of
established PHS referral guidelines. An appropriate scientific review group
convened in accordance with the standard NIH peer review procedures
http://www.csr.nih.gov/refrev.htm will evaluate applications for scientific
and technical merit.
As part of the initial merit review, all applications will:
o Receive a written critique.
o Undergo a selection process in which only those applications deemed to have
the highest scientific merit, generally the top half of applications under
review, will be discussed and assigned a priority score.
o Receive a second level review by the appropriate national advisory council
or board.
REVIEW CRITERIA
Note that the page limit for the Research Plan in R21 applications under this
Program Announcement is 15 pages, as opposed to 25 pages for R01 applications.
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
your application in order to judge the likelihood that the proposed research
will have a substantial impact on the pursuit of these goals:
o Significance
o Approach
o Innovation
o Investigator
o Environment
The scientific review group will address and consider each of these criteria
in assigning your application=s overall score, weighting them as appropriate
for each application. Your 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, you 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 your study address an important problem? If the aims of
your application are achieved, how do they advance scientific knowledge? 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? Do you acknowledge potential problem areas and consider alternative
tactics?
(3) INNOVATION: Does your project employ novel concepts, approaches or
methods? Are the aims original and innovative? Does your project challenge
existing paradigms or develop new methodologies or technologies?
(4) INVESTIGATOR: Are you appropriately trained and well suited to carry out
this work? Is the work proposed appropriate to your experience level as the
principal investigator and to that of other researchers (if any)?
(5) ENVIRONMENT: Does the scientific environment in which your 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?
For R21 applications, the above stated criteria will be reviewed, but it will
be noted that the R21 is a developmental/exploratory grant mechanism that is
used for high risk/high impact projects to generate preliminary data to
develop novel hypotheses. Therefore, review standards for preliminary data and
past performances are not applicable for this mechanism.
ADDITIONAL REVIEW CRITERIA
In addition to the above criteria, your application will also be reviewed with
respect to the following:
PROTECTIONS: 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.
INCLUSION: The adequacy of plans to include subjects from both genders, all
racial and ethnic groups (and subgroups), and children as appropriate for the
scientific goals of the research. Plans for the recruitment and retention of
subjects will also be evaluated. (See Inclusion Criteria included in the
section on Federal Citations, below.)
BUDGET: The reasonableness of the proposed budget and the requested period of
support in relation to the proposed research.
AWARD CRITERIA
Applications submitted in response to a PA will compete for available funds
with all other recommended applications. The following will be considered in
making funding decisions:
o Scientific merit of the proposed project as determined by peer review.
o Availability of funds.
o Relevance to program priorities.
REQUIRED FEDERAL CITATIONS
INCLUSION OF WOMEN AND MINORITIES IN CLINICAL RESEARCH
It is the policy of the NIH that women and members of minority groups and
their sub-populations must be included in all NIH-supported clinical research
projects unless a clear and compelling justification is provided indicating
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 clinical research should read the AMENDMENT "NIH
Guidelines for Inclusion of Women and Minorities as Subjects in Clinical
Research - Amended, October, 2001," published in the NIH Guide for Grants and
Contracts on October 9, 2001 (https://grants.nih.gov/grants/guide/notice-
files/NOT-OD-02-001.html), a complete copy of the updated Guidelines are
available at
https://grants.nih.gov/grants/funding/women_min/guidelines_amended_10_2001.htm
The amended policy incorporates: the use of an NIH definition of clinical
research, updated racial and ethnic categories in compliance with the new OMB
standards, clarification of language governing NIH-defined Phase III clinical
trials consistent with the new PHS Form 398, and updated roles and
responsibilities of NIH staff and the extramural community. The policy
continues to require for all NIH-defined Phase III clinical trials that: a)
all applications or proposals and/or protocols must provide a description of
plans to conduct analyses, as appropriate, to address differences by
sex/gender and/or racial/ethnic groups, including subgroups if applicable,
and b) investigators must report annual accrual and progress in conducting
analyses, as appropriate, by sex/gender and/or racial/ethnic group
differences.
INCLUSION OF CHILDREN AS PARTICIPANTS IN RESEARCH INVOLVING HUMAN SUBJECTS
The NIH maintains a policy 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 is available at
https://grants.nih.gov/grants/funding/children/children.htm
REQUIRED EDUCATION ON THE PROTECTION OF HUMAN SUBJECT PARTICIPANTS
NIH policy requires education on the protection of human subject participants
for all investigators submitting NIH proposals for research involving human
subjects. You will find this policy announcement in the NIH Guide for Grants
and Contracts Announcement, dated June 5, 2000, at
https://grants.nih.gov/grants/guide/notice-files/NOT-OD-00-039.html.
HUMAN EMBRYONIC STEM CELLS (hESC)
Criteria for federal funding of research on hESCs can be found at
https://grants.nih.gov/grants/stem_cells.htm and
https://grants.nih.gov/grants/guide/notice-files/NOT-OD-02-005.html
Only research using hESC lines that are registered in the NIH Human Embryonic
Stem Cell Registry will be eligible for Federal funding (see
http://escr.nih.gov.) It is the responsibility of the applicant to provide the
official NIH identifier(s)for the hESC line(s)to be used in the proposed
research. Applications that do not provide this information will be returned
without review.
PUBLIC ACCESS TO RESEARCH DATA THROUGH THE FREEDOM OF INFORMATION ACT
The Office of Management and Budget (OMB) Circular A-110 has been revised to
provide public access to research data through the Freedom of Information Act
(FOIA) under some circumstances. Data that are (1) first produced in a project
that is supported in whole or in part with Federal funds and (2) cited
publicly and officially by a Federal agency in support of an action that has
the force and effect of law (i.e., a regulation) may be accessed through FOIA.
It is important for applicants to understand the basic scope of this
amendment. NIH has provided guidance at
https://grants.nih.gov/grants/policy/a110/a110_guidance_dec1999.htm
Applicants may wish to place data collected under this PA in a public archive,
which can provide protections for the data and manage the distribution for an
indefinite period of time. If so, the application should include a description
of the archiving plan in the study design and include information about this
in the budget justification section of the application. In addition,
applicants should think about how to structure informed consent statements and
other human subjects procedures given the potential for wider use of data
collected under this award.
URLs IN NIH GRANT APPLICATIONS OR APPENDICES
All applications and proposals for NIH funding must be self-contained within
specified page limitations. Unless otherwise specified in an NIH solicitation,
Internet addresses (URLs) should not be used to provide information necessary
to the review because reviewers are under no obligation to view the Internet
sites. Furthermore, we caution reviewers that their anonymity may be
compromised when they directly access an Internet site.
HEALTHY PEOPLE 2010
The Public Health Service (PHS) is committed to achieving the health promotion
and disease prevention objectives of "Healthy People 2010," a PHS-led national
activity for setting priority areas. This PA is related to one or more of the
priority areas. Potential applicants may obtain a copy of "Healthy People
2010" at http://www.health.gov/healthypeople
AUTHORITY AND REGULATIONS
This program is described in the Catalog of Federal Domestic Assistance No.
93.3113 and is not subject to the intergovernmental review requirements of
Executive Order 12372 or Health Systems Agency review. Awards are made under
authorization of Sections 301 and 405 of the Public Health Service Act as
amended (42 USC 241 and 284 and administered under NIH grants policies
described at https://grants.nih.gov/grants/policy/policy.htm
The PHS strongly encourages all grant recipients to provide a smoke-free
workplace and discourage the use of all tobacco products. In addition, Public
Law 103-227, the Pro-Children Act of 1994, prohibits smoking in certain
facilities (or in some cases, any portion of a facility) in which regular or
routine education, library, day care, health care, or early childhood
development services are provided to children. This is consistent with the PHS
mission to protect and advance the physical and mental health of the American
people.
