Opportunity Summary:

Neural Regulation of Cancer (R21) (Funding Opportunity Number PAR 16-246) is a National Institutes of Health (NIH) discretionary grant opportunity administered under HHS (listed as HHS-NIH11) that supports early-stage, exploratory research on how the nervous system influences cancer. The central goal is to bring neuroscience and cancer biology together in genuinely collaborative, transdisciplinary projects that can open up new directions in understanding tumor behavior. Rather than focusing on cancers of the central nervous system, the emphasis is on non-CNS tumors and on clarifying how neural inputs and neural-associated mechanisms may contribute to tumor initiation, tumor growth and progression, and the spread of cancer through metastasis.

The FOA is designed to encourage investigators to leverage established neuroscience strengths, including specialized tools, experimental models, and reagents, and apply them to cancer questions where the role of neural regulation is still emerging. In practice, this could include using modern neural circuit-mapping approaches, neurophysiology, neuroimmune interaction models, neurotransmitter and neuropeptide signaling assays, or advanced imaging and genetic manipulation systems to uncover cancer-relevant mechanisms. The rationale is that the nervous system is not just a bystander; it can shape the tumor microenvironment, influence inflammation and immune activity, affect angiogenesis and tissue remodeling, and potentially provide signals that cancers exploit to thrive and disseminate. By bringing neuroscience-grade methods into cancer research, the program aims to reveal mechanisms that traditional tumor-focused approaches might miss, and to translate those insights into new prevention and treatment strategies.

This is an R21 mechanism, which typically indicates a focus on high-risk, high-reward exploratory studies that generate foundational data, establish feasibility, or test innovative ideas that could later be scaled into larger projects. Consistent with that exploratory intent, the listed award ceiling is $200,000, supporting projects that are sharply focused and hypothesis-driven but not necessarily fully mature in terms of preliminary evidence. The opportunity was created and posted on May 9, 2016, with a listed closing date of June 27, 2019 (original and current closing dates both shown as June 27, 2019), indicating the specific application deadline for that cycle.

Eligibility is broad and includes many types of domestic institutions and organizations, reflecting NIH’s intent to attract diverse, cross-sector teams. Eligible applicants include state, county, and city or township governments; special district governments; independent school districts; public and state-controlled institutions of higher education; private institutions of higher education; federally recognized Native American tribal governments and other Native American tribal organizations; public housing authorities/Indian housing authorities; nonprofits with or without 501(c)(3) status (other than institutions of higher education); for-profit organizations other than small businesses; small businesses; and additional eligible entities as described in the FOA’s eligibility clarification text. The program is categorized under Education and Health, with CFDA numbers 93.396 (and an additional CFDA listing shown as 93.396 in the provided data), consistent with NIH health research funding.

Overall, the opportunity targets projects that can credibly connect neuroscience mechanisms to concrete cancer outcomes, such as identifying neural pathways or signaling molecules that promote tumor growth, determining how stress-related neural activity influences metastasis, clarifying how peripheral nerves interact with tumor and immune cells, or discovering neural-regulated microenvironmental changes that could be therapeutically interrupted. The intended payoff is a clearer mechanistic understanding of how the nervous system contributes to cancer, plus new ideas for interventions that prevent or treat non-CNS tumors by accounting for, or directly targeting, neural regulation.
