Epithelial-derived IL-33 promotes intestinal tumorigenesis in Apc ^Min/+ mice.

ABSTRACT: Increased expression of Interleukin (IL)-33 has been detected in intestinal samples of patients with ulcerative colitis, a condition associated with increased risk for colon cancer, but its role in the development of colorectal cancer has yet to be fully examined. Here, we investigated the role of epithelial expressed IL-33 during development of intestinal tumors. IL-33 expression was detected in epithelial cells in colorectal cancer specimens and in the Apc ^Min/+ mice. To better understand the role of epithelial-derived IL-33 in the intestinal tumorigenesis, we generated transgenic mice expressing IL-33 in intestinal epithelial cells (V33 mice). V33 Apc ^Min/+ mice, resulting from the cross of V33 with Apc ^Min/+ mice, had increased intestinal tumor burden c
