P143 epithelial-derived selenoprotein p protects from colitis-associated carcinogenesis

Patients with inflammatory bowel disease demonstrate selenium nutritional deficiencies and are at increased risk  for colon cancer. Previously, we determined that global loss of the selenium-containing antioxidant protein, Selenoprotein P (SELENOP), exacerbates experimental colitis-associated cancer (CAC). Using a variety of tissue-specific knockout mouse lines, we further determined that epithelial-derived SELENOP served as the primary mediator of disease severity, and Villin-Cre; Selenop f/f (Selenop ΔIEC) mice have increased tumor incidence, number, size, and dysplasia as compared to WT cohorts.
