Manipulation of Gut Microbiota With Flaxseed Could Reduce Breast Cancer Risk

A new study demonstrates that the human gut microbiome may be a factor in breast health. Lifestyle and diet have long been known to affect human health. In the study, flaxseed components called lignans were shown to influence the relationship between gut microorganisms and the expression of mammary gland microRNAs (miRNAs). A subset of these miRNAs regulates the genes involved in breast cancer, including genes that control cell proliferation and migration. The study was published in Microbiology Spectrum, a journal of the American Society for Microbiology.
"The gastrointestinal microbiota plays an important role in modifying many components of our diet to impact human health," said Jennifer Auchtung, Ph.D., Assistant Professor in the Food Science and Technology Department at the University of Nebraska -- Lincoln, the editor who coordinated the review of the paper.
"In this study, we found correlations between diets enriched in flaxseed, cecal microbiota composition and miRNA profiles in the mammary gland that regulate many pathways, including those involved in cancer development. This preliminary study supports further research into the role that the microbiota plays in dietary approaches to reduce risk factors associated with disease."
