| Research Abstract |
Treatment with anti-tumor necrosis factor (TNF) mAb has been accepted as a successful therapy for patients with inflammatory bowel diseases (IBD). It has been recently reported that blockade of TNF receptor (TNFR) signaling in infiltrating hematopoietic cells may prevents the development of colitis-associated cancer (CAC). However, it remains unclear whether the TNF signaling in the epithelial cells is also involved in the development of CAC. To investigate this, we studied the effects of anti-TNF mAb in animal models of colitis and CAC. Our studies suggest that the TNFR signaling in intestinal epithelial cells may be directly involved in the development of CAC with persistent colitis, and imply that the maintenance therapy with anti-TNF mAb may prevent the development of CAC in patients with IBD.
