Abstract:


It is well accepted that inflammatory bowel disease (IBD), including ulcerative colitis and Crohn’s disease, is one of high risk factors for colorectal cancer (CRC). This supports the notion that inflammation plays a key role in cancer development. Epidemiologic studies have shown that vitamin D (Vit D) deficiency is associated with IBD and various types of cancer including colorectal cancer. Clinical trials and mouse models have shown that Vit D is beneficial in preventing or ameliorating inflammation and carcinogenesis. Mechanism studies show that Vit D played wide-spectrum roles in anti-inflammation, immunoregulation, and anti-cancer activities. In this review, we summarized and updated the findings on Vit D, IBD and colitis-associated colorectal cancer (CAC) with the emphasis on the effects of Vit D on anti-inflammation, EMT and cancer stem cells (CSC).

Keywords:
