Effect of O-GlcNAc transferase deficiency on intestinal epithelial cells in mice

ABSTRACT: O-GlcNAcylation is the modification of serine and threonine residues with beta-N-acetylglucosamine (O-GlcNAc) on intracellular proteins. To investigate the role of protein O-GlcNAcylation on intestinal homeostasis, we generated intestinal epithelial cell (IEC)-specific O-GlcNAc transferase (OGT) knockout in mice. The KO mice developed spontanous intestinal inflammation. To determine the underlying molecular mechanisms, we performed RNA sequencing of ileum and colon epithelial cells of wildtype and IEC-OGT KO mice. Overall design: mRNA profiling of intestinal epithelial cells (IECs) from the ileum and colon of 10-week-old wildtype and IEC-OGT KO male mice.

Post-translational modifications in intestinal epithelial cells (IECs) allow for precise control in intestinal homeostasis, the breakdown of which may precipitate the pathological damage and inflammation in inflammatory bowel disease. The O-linked β-N-acetylglucosamine (O-GlcNAc) modification on intracellular proteins controls diverse biological processes; however, its roles in intestinal homeostasis are still largely unexplored. Here, we found that levels of protein O-GlcNAcylation and the expr  ...[more]
