FFAR2-FFAR3 receptor heteromerization modulates short-chain fatty acid sensing
Free fatty acid receptors 2 and 3 (FFAR2/FFA2/GPR43 and FFAR3/FFA3/GPR41) are mammalian receptors for gut microbiota-derived short-chain fatty acids (SCFAs). These receptors are promising drug targets for obesity, colitis, colon cancer, asthma, and arthritis. Here, we demonstrate that FFAR2 and FFAR3 interact to form a heteromer in primary human monocytes and macrophages via proximity ligation ...
متن کاملButyrate and other short-chain fatty acids increase the rate of lipolysis in 3T3-L1 adipocytes
We determined the effect of butyrate and other short-chain fatty acids (SCFA) on rates of lipolysis in 3T3-L1 adipocytes. Prolonged treatment with butyrate (5 mM) increased the rate of lipolysis approximately 2-3-fold. Aminobutyric acid and acetate had little or no effect on lipolysis, however propionate stimulated lipolysis, suggesting that butyrate and propionate act through their shared acti...
متن کاملRegulation of short-chain fatty acid production.
Short-chain fatty acid (SCFA) formation by intestinal bacteria is regulated by many different host, environmental, dietary and microbiological factors. In broad terms, however, substrate availability, bacterial species composition of the microbiota and intestinal transit time largely determine the amounts and types of SCFA that are produced in healthy individuals. The majority of SCFA in the gu...
متن کاملAn Na(+)-independent short-chain fatty acid transporter contributes to intracellular pH regulation in murine colonocytes
Short-chain fatty acids (SCFAs) are the major anions in the colonic lumen. Experiments studied how intracellular pH (pHi) of isolated colonocytes was affected by exposure to SCFAs normally found in the colon. Isolated crypt fragments were loaded with SNARF-1 (a fluorescent dye with pH-sensitive excitation and emission spectra) and studied in a digital imaging microscope. Intracellular pH was me...
متن کاملHyperpolarized Butyrate: A Metabolic Probe of Short Chain Fatty Acid Metabolism in the Heart
PURPOSE Butyrate, a short chain fatty acid, was studied as a novel hyperpolarized substrate for use in dynamic nuclear polarization enhanced magnetic resonance spectroscopy experiments, to define the pathways of short chain fatty acid and ketone body metabolism in real time. METHODS Butyrate was polarized via the dynamic nuclear polarization process and subsequently dissolved to generate an i...
