GPR65 (TDAG8) inhibits intestinal inflammation and colitis-associated colorectal cancer development in experimental mouse models.

ABSTRACT: GPR65 (TDAG8) is a proton-sensing G protein-coupled receptor predominantly expressed in immune cells. Genome-wide association studies (GWAS) have identified GPR65 gene polymorphisms as an emerging risk factor for the development of inflammatory bowel disease (IBD). Patients with IBD have an elevated risk of developing colorectal cancer when compared to the general population. To study the role of GPR65 in intestinal inflammation and colitis-associated colorectal cancer (CAC), colitis and CAC were induced in GPR65 knockout (KO) and wild-type (WT) mice using dextran sulfate sodium (DSS) and azoxymethane (AOM)/DSS, respectively. Disease severity parameters such as fecal score, colon shortening, histopathology, and mesenteric lymph node enlargement were aggravated in GPR65 KO mice compared to
