Scientists uncover how high-fat diet drives colorectal cancer growth
Experimental drug candidate slows cancer progression in mouse model
A new study led by Salk Institute scientists suggests that high-fat diets fuel colorectal cancer growth by upsetting the balance of bile acids in the intestine and triggering a hormonal signal that lets potentially cancerous cells thrive. The findings, which appeared in Cell on February 21, 2019, could explain why colorectal cancer, which can take decades to develop, is being seen in younger people growing up at a time when higher-fat diets are common.
"This study provides a new way to lower inflammation, restore intestinal health and to dramatically reduced tumor progression," says Professor Ronald Evans, director of the Gene Expression Laboratory, Howard Hughes Medical Institute investigator and holder of Salk's March of Dimes Chair in Molecular and Developmental Biology. Dr. Evans is also the Project Leader of Project 2 for the UCSD Superfund Research Center in which this study was partially funded.
