The National Institutes of Health (NIH) is inviting applications for the funding opportunity titled "Mechanistic links between diet, lipid metabolism, and tumor growth and progression (U01 Clinical Trial Not Allowed)." This initiative aims to explore the molecular mechanisms that connect dietary factors and lipid metabolism to cancer growth and progression, emphasizing the need for interdisciplinary research that bridges nutrition and molecular metabolism. The program is particularly focused on understanding how dietary variations, such as high-fat or ketogenic diets, influence lipid metabolism in cancer and their implications for tumor biology and patient outcomes. Eligible applicants can receive up to $500,000 per year for a project period of up to five years, with applications accepted until October 23, 2025.
