pubmed:abstractText |
G proteins are involved in cellular signalling and regulate a variety of biological processes including differentiation and development. We have generated mice deficient for the G protein subunit alpha i2 (G alpha i2) by homologous recombination in embryonic stem cells. G alpha i2-deficient mice display growth retardation and develop a lethal diffuse colitis with clinical and histopathological features closely resembling ulcerative colitis in humans, including the development of adenocarcinoma of the colon. Prior to clinical symptoms, the mice show profound alterations in thymocyte maturation and function. The study of these animals should provide important insights into the pathogenesis of ulcerative colitis as well as carcinogenesis.
