Opportunity Summary:

The NIH funding opportunity announcement PAS 06 466, titled "The Role of Nuclear Receptors in Tissue and Organismal Aging (R21)," supports early stage, exploratory research that looks at how nuclear receptors help shape the biology of aging and how those aging processes connect to disease and decline in midlife and older age. The scientific focus is on uncovering underlying mechanisms, especially the roles of nuclear receptors, their co-regulators, and related intracellular signaling pathways that influence aging at the tissue level and across the whole organism. In practical terms, the FOA is aimed at projects that can open up new directions, test new hypotheses, or generate preliminary mechanistic evidence about how nuclear receptor systems contribute to aging trajectories and age-associated pathophysiology.

This announcement uses the Exploratory/Developmental Research Grant mechanism (R21), which is generally intended for higher-risk, earlier proof-of-concept work compared with larger, more mature research programs. The R21 structure is meant to encourage innovative ideas and pilot-style studies where the science is promising but not yet fully established. The FOA also notes that it runs in parallel with a companion announcement, PAS 06 467, which has the same scientific scope but uses the R01 mechanism, a better fit for more developed projects with a stronger base of preliminary data and a longer, more comprehensive research plan.

Funding levels and the number of awards are not fixed and will depend on congressional appropriations, participating institute budgets, and how many strong applications are received that fall within the relevant funding lines. The estimated total funding listed for the FOA is $1,200,000, and the stated award ceiling is $200,000. Because projects can vary widely in approach, scope, and cost, the NIH indicates that both the size and duration of awards may vary, and that final decisions will reflect the number, quality, duration, and budget needs of the submitted proposals.

Multiple NIH institutes and centers are involved, reflecting the cross-cutting nature of nuclear receptor biology in aging and disease. The FOA specifically references participation and funding lines tied to the National Institute on Aging (NIA), the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), the National Cancer Institute (NCI), and the National Institute of Environmental Health Sciences (NIEHS). The associated CFDA program areas listed in the source data include Aging Research (93.866), Diabetes, Digestive, and Kidney Diseases Extramural Research (93.847), Cancer Biology Research (93.396), and Environmental Health (93.113), which signals that projects could be relevant to a range of age-linked conditions and biological contexts, including metabolic disease, cancer-related processes, and environmentally influenced mechanisms.

Eligibility is broad. A wide range of domestic applicants can apply, including public and private institutions of higher education, nonprofits with or without 501(c)(3) status, for-profit organizations (including small businesses and other for-profits), and many units of government (state, county, city or township, special district governments, public housing authorities, and independent school districts). The FOA also allows applications from federally recognized tribal governments and other tribal organizations. Importantly, foreign institutions are eligible to apply, and eligible federal agencies can also submit applications. Applicants may submit more than one application as long as each submission is scientifically distinct, which is useful for research groups that want to pursue multiple mechanistic angles or different model systems without forcing everything into a single proposal.

From an administrative standpoint, this is a discretionary grant opportunity issued by the National Institutes of Health. It was posted July 10, 2006, with later record dates showing creation on December 5, 2008. The original closing date is listed as July 2, 2009, with a current closing date of September 7, 2009, and an archive date of October 7, 2009. The FOA indicates there is no cost sharing or matching requirement. For applicants needing the full text or experiencing access issues, the announcement points to the NIH Grants Guide page (linked in the listing) and provides NIH Office of Extramural Research webmaster contact information for technical difficulties.

Overall, the opportunity is designed to stimulate innovative, mechanistic research on how nuclear receptor networks and their regulatory partners influence aging biology and the development of age-associated disorders, using the R21 mechanism to enable exploratory studies that can establish new lines of evidence and set the stage for future, larger-scale work (including, for some projects, a potential later transition to an R01 pathway via the companion FOA).

Frequently Asked Questions (FAQs)

What is the funding opportunity and what is its official title?

The opportunity is an NIH Funding Opportunity Announcement (FOA) identified as PAS 06 466. Its title is "The Role of Nuclear Receptors in Tissue and Organismal Aging (R21)."

What is the main purpose of this FOA?

This FOA supports early-stage, exploratory research aimed at understanding how nuclear receptors shape the biology of aging and how aging processes connect to disease and functional decline in midlife and older age.

What kind of research does the FOA encourage?

It encourages projects that open new directions, test new hypotheses, or generate preliminary mechanistic evidence about how nuclear receptor systems contribute to aging trajectories and age-associated pathophysiology.

What scientific areas are emphasized in the announcement?

The scientific focus is on uncovering underlying mechanisms, particularly the roles of nuclear receptors, their co-regulators, and related intracellular signaling pathways that influence aging at the tissue level and across the whole organism.

What grant mechanism is used, and what does that imply about project maturity?

The announcement uses the Exploratory/Developmental Research Grant mechanism (R21). This mechanism is generally intended for higher-risk, earlier proof-of-concept work and pilot-style studies where the science is promising but not yet fully established compared with larger, more mature research programs.

Is there a companion announcement for more developed projects?

Yes. PAS 06 466 runs in parallel with a companion announcement, PAS 06 467, which has the same scientific scope but uses the R01 mechanism, which is better suited for more developed projects with stronger preliminary data and a longer, more comprehensive research plan.

How much funding is available in total under this FOA?

The estimated total funding listed for the FOA is $1,200,000. Actual funding depends on congressional appropriations, participating institute budgets, and the number of strong applications received within relevant funding lines.

Is there a maximum award amount (award ceiling)?

Yes. The stated award ceiling is $200,000.

Are the number of awards and award sizes fixed?

No. Funding levels and the number of awards are not fixed. NIH indicates that both the size and duration of awards may vary, and final decisions will reflect the number, quality, duration, and budget needs of submitted proposals.

Which NIH Institutes and Centers are involved?

The FOA references participation and funding lines tied to the National Institute on Aging (NIA), the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), the National Cancer Institute (NCI), and the National Institute of Environmental Health Sciences (NIEHS).

What program areas (CFDA) are associated with this opportunity?

The associated CFDA program areas listed include Aging Research (93.866), Diabetes, Digestive, and Kidney Diseases Extramural Research (93.847), Cancer Biology Research (93.396), and Environmental Health (93.113).

What does the cross-cutting institute participation suggest about project fit?

It signals that relevant projects may span multiple biological and disease contexts linked to aging, including areas such as metabolic disease, cancer-related processes, and environmentally influenced mechanisms, as long as the work aligns with the FOA's emphasis on nuclear receptor biology in aging.
