Abstract:
Inflammatory bowel disease refers to chronic inflammatory disorders that affect the gastrointestinal tract. Ubiquitination is an important protein post-translational modification. In recent years, the research of ubiquitination-deubiquitination system in the development of inflammatory bowel disease has become a hot spot. Up to now, the E3 ubiquitin ligases such as ring finger protein 183 (RNF183), RNF20, Itch and A20 were well studied in inflammatory bowel disease. RNF183 promotes the activation of the NF-κB pathway by increasing the ubiquitination and degradation of IκBα; RNF20 drives histone H2B monoubiquitylation, downregulates a panel of inflammation-associated genes; Itch inhibits IL-17-mediated colon inflammation by retinoid acid related orphan receptor γt ubiquitination; A20 has ubiquitinating-deubiquitinating activity to regulates colon inflammation. This article reviews the role and regulatory mechanism of RNF183, RNF20, Itch and A20 in the pathogenesis of inflammatory bowel disease.
