Research progress on the role of SIRT in intestinal barrier / 基础医学与临床

SIRT is a family of highly conserved nicotine adenine dinucleotide ( NAD+)-dependent protein deacetylase which regulates several processes including cell gene stability , metabolism , aging and apoptosis . Studies have shown that SIRT has protective effects on intestinal barrier , which influences the structure and function of intestinal barrier by controlling the release of inflammatory cytokines , regulating the expression of tight junction protein in intestinal epithelial , and changing the number of Paneth and goblet cells in the intestine .
