[ Summary ] |
Patients with inflammatory bowel disease (IBD) have an increased risk of colitis-associated colorectal cancer (CAC). CAC often acquires chemoresistance, resulting in poorer prognosis than that of sporadic colorectal cancer (CRC). The mechanism by which CAC enhances malignant potential remains unknown. In this issue, we focus on whether the pathological characteristics of CAC that result in enrichment of mucinous carcinoma are related to regulation of intestinal differentiation. Deregulation of the stability of proteins including Atoh1 has been shown to be associated with the mucinous form and higher malignant potential of CAC. |
