Exacerbated experimental colitis in TNFAIP8-deficient mice.

ABSTRACT: The TNF-α-induced protein 8 (TNFAIP8 or TIPE) is a risk factor for cancer and bacterial infection, and its expression is upregulated in a number of human cancers. However, its physiologic and pathologic functions are unclear. In this study, we describe the generation of TIPE-deficient mice and their increased sensitivity to colonic inflammation. TIPE-deficient mice were generated by germ line gene targeting and were born without noticeable developmental abnormalities. Their major organs, including lymphoid organs and intestines, were macroscopically and microscopically normal. However, after drinking dextran sodium sulfate-containing water, TIPE-deficient mice developed more severe colitis than wild type mice did, as demonstrated by decreased survival rates, increased body weight loss, and
