Diet, Lipid Metabolism, and Tumor Growth and Progression (DLT) Program
The Diet, Lipid Metabolism, and Tumor Growth and Progression (DLT) Program is investigating mechanistic links between diet, lipid metabolism, and tumor growth/progression. This initiative also supports the development of new tools and models in an emerging area of research at the intersection of nutrition and molecular metabolism.
The Program aligns with the 2020 – 2030 Strategic Plan for NIH Nutrition Research, which “emphasizes cross-cutting, innovative opportunities to advance nutrition research across a wide range of areas":
- Goal 1: Spur Discovery and Innovation through Foundational Research
- Goal 4: Reduce the Burden of Disease in Clinical Settings
Investigators of the DLT Program are supporting progress towards these goals through fundamental studies of the role of diet and lipid metabolism in cancer and by identifying nutrition-related molecular interactions with tumor biology that could, ultimately, be leveraged to improve clinical cancer care.

DLT News
New grants for the DLT Program were awarded in the Spring and Fall of 2024.
Drs. Nika Danial and Mariella Filbin with the Dana-Farber DLT Project are examining the role of dietary fatty acids in the growth of diffuse midline gliomas, a type of aggressive pediatric brain tumor.
Dr. Evan Lien with the Van Andel Research Institute DLT Project is studying how diet-driven alterations to the balance of saturated vs. unsaturated fatty acids within tumors influences cancer progression and the response to therapy.
Drs. Tim Yeatman and Ganesh Halade with the University of South Florida DLT Project are investigating the role of arachidonic acid metabolism in modulating the immune microenvironment of colorectal cancer.
Drs. Heather Christofk, Guido Eibl, and Katherine Plath with the UCLA DLT Project are examining how diets enriched in specific fatty acids promote pancreatic cancer initiation and progression.
Drs. Amandine Chaix, Greg Ducker, and Keren Hilgendorf with the University of Utah DLT Project are studying mechanisms by which dietary lipids drive obesity-accelerated breast cancer growth and identifying potential metabolic vulnerabilities in breast tumors.
