The National Institutes of Health (NIH) is offering a funding opportunity for epidemiologic research focused on emerging risk factors associated with liver cancer in the United States, specifically through the R01 grant mechanism. This initiative aims to investigate novel hypotheses regarding biological, environmental, and social factors, as well as their interactions with established risk factors like viral hepatitis, to better understand their role in the development of hepatocellular carcinoma and other liver cancer types. The program encourages applications that explore non-viral contributors, such as obesity and diabetes, and seeks to produce insights that will inform evidence-based strategies for liver cancer prevention and control. Interested applicants, including higher education institutions, nonprofit organizations, and foreign entities, must submit their proposals by February 5, 2025, and can find additional information at NIH Grants.
