Inflammatory bowel disease (IBD) is marked by inflammation mediated epithelial-mucosal damage. The intestinal epithelial forms a tight barrier displaying two contrasting functions: restricting the entry of potentially harmful substances while, on the other hand allowing the selective passage of nutrients. The damaged epithelial-mucosal barrier causes the exposure of mucosa layers to luminal inflammatory contents. This eventually leads to the leaky epithelium, exposing the immune cells, release of various cytokines, and results in loss of epithelial homeostasis. Therefore, maintenance of healthy epithelial- mucosal lining is critical during IBD recovery. Notch signaling is an evolutionarily conserved molecular pathway crucial for the development and homeostasis of most tissues. Notably, the deregulation of Notch signaling is involved in IBD (Ulcerative colitis and Crohn’s disease). Notch signaling also plays a vital role in wound healing and tissue repair. Here, we investigated the role of Notch-1 signaling in wound healing and regeneration of colonic epithelium during colitis recovery phase by using conditional deletion of Notch-1 in colonic epithelium of mice. We used colonic carcinoma cell line HCT116 transiently transfected with Notch1 intracellular domain (NICD) to support in vivo data. We observed that deletion of Notch1 among mice was associated with compromised healing after colitis. Therefore, targeting the Notch-1 pathway might provide a novel therapeutic strategy for the patients recovering from colitis.
