KSR1 protects from interleukin-10 deficiency-induced colitis in mice by suppressing T-lymphocyte interferon-γ production. Gastroenterology. 2011 Jan;140(140). 265-74.

Immunological disorders of the gastrointestinal tract such as inflammatory bowel disease often result in recurrent and persistently elevated levels of proinflammatory cytokines. Kinase suppressor of Ras 1 (KSR1) is involved in tumor necrosis factor-mediated colon epithelial cell survival, yet its role in chronic inflammation has not been defined. In this study, we tested the hypothesis that KSR1 is protective against spontaneous experimental colitis.
