The National Institutes of Health (NIH) has announced a funding opportunity for research on the biology of bladder cancer through the R21 Exploratory/Developmental Grant mechanism (PAR-22-219). This initiative aims to encourage applications that investigate the biological mechanisms underlying bladder cancer, a significant health issue both in the United States and globally, with a focus on understanding cancer initiation and progression. The grant supports projects that explore molecular and cellular functions of the bladder, with a maximum funding amount of $275,000 available over two years, and applications are due by September 7, 2025. Interested applicants can find more information and submit inquiries via the NIH OER Webmaster at OERWebmaster03@od.nih.gov, and detailed guidelines are available at the provided link.
