The study of O-GalNAcylation repair on MUC2 and E-cadherin of intestinal epithelial cells damaged by lipopolysaccharides
This study reveals that LPS-induced intestinal epithelial damage disrupts MUC2 O-GalNAcylation and adherens junction integrity, but GalNT3 overexpression restores long-chain O-glycans on MUC2, stabilizing E-cadherin and calcium homeostasis to repair the mucosal barrier and mitigate LPS translocation.
