    Inflammatory bowel disease (IBD) features mucus and epithelial barrier dysfunction, with regulatory mechanisms remaining inconsistent across studies.

  • 2

    A meta-analysis of 26 human colonic transcriptomic datasets identified 3,129 differentially expressed genes in Crohn's disease and 3,729 in ulcerative colitis.

    Key pathways upregulated in IBD include goblet-cell differentiation, mucin transcription, and endoplasmic reticulum quality control.

  • 4

    Mucus barrier dysfunction in IBD reflects inflammatory remodeling rather than primary secretory collapse, sharing ER-stress and microbial response signatures.

    Integrating human and murine datasets reveals candidate pathways that may stabilize mucin folding and preserve host-microbe spatial segregation in intestinal disease.
