Abstract Short-chain fatty acids, generated in colon by bacterial fermentation of dietary fiber, protect against colorectal cancer and inflammatory bowel disease. Among these metabolites, butyrate is biologically most relevant. GPR109A a G-protein–coupled receptor for nicotinate but recognizes with low affinity. Millimolar concentrations are needed to activate the receptor. Although colonic lumen sufficient maximally, there have been no reports on expression/function this tissue. Here we...
