Metabolism In The Colonocyte: Where Bacteria And Diet Meet, Bohye Park

The host-microbiome interaction and the functions of microbial-derived metabolites, including butyrate, are important in colon health. Butyrate is the preferred energy source in colonocytes and has multiple physiological functions in the colon. A metabolic shift in colonocytes toward increased glucose utilization from butyrate oxidation is followed by several critical genetic modifications in cancerous colonocytes. Moreover, it has been suggested that the gut-microbiota composition is influenced by environmental factors, such as diets and the host's physiological status. Therefore, an understanding of the role of colonocyte metabolism toward impacting the host-microbiota commensal relationship would be an important step in understanding the functional …
Butyrate, A Major Bacterial-Derived Metabolite: Understanding Of Butyrate Metabolism In Cancerous Colonocytes, Anna Han
Doctoral Dissertations
The prohibitory effects of dietary fiber in colorectal cancer have been identified, although the detailed mechanism of this beneficial effect remain unclear. Butyrate, a fermentation metabolite of fiber, has anti-cancer properties by inhibiting cell proliferation and increasing cell apoptosis in cancer cells. A major mechanism, whereby butyrate exerts anti-cancer effects in colorectal cancer, is its role as an HDAC inhibitor. Moreover, it has been suggested that the metabolic fate of butyrate is significantly related to its role as an HDAC inhibitor. Therefore, understanding butyrate metabolism in cancerous colonocytes sheds important light on how butyrate has its selective and inhibitory effects …
