The National Institutes of Health (NIH) is inviting proposals for a funding opportunity titled "Mechanistic links between diet, lipid metabolism, and tumor growth and progression" under the cooperative agreement mechanism. This initiative aims to support research that investigates the molecular mechanisms linking lipid metabolism to tumor dynamics, particularly focusing on the impact of dietary factors, such as high-fat and ketogenic diets, on cancer progression. The program encourages innovative approaches and collaboration among researchers, facilitating entry for new investigators with limited preliminary data requirements. Interested applicants can apply for funding up to $275,000 over a two-year period, with applications due by October 23, 2025. For further information, applicants may contact NIH Grants Information at grantsinfo@nih.gov or visit the opportunity's webpage at https://grants.nih.gov/grants/guide/pa-files/PAR-23-052.html.
