摘要: Keap1-Nrf2信号通路的激活是细胞对抗氧化应激的重要机制。氧化应激条件下,Keap1受到谷胱甘肽化、烷基化以及S-巯基化等翻译后修饰(PTM)的影响,与Nrf2的结合被减弱,导致Nrf2积累、核易位以及下游解毒和抗氧化防御蛋白质的表达和转录。Keap1的PTM参与调控癌、帕金森病和动脉粥样硬化等多种氧化应激相关疾病,例如烷基化抑制腹主动脉瘤形成、甲基化促进乳腺癌固有抵抗以及S-巯基化改善动脉粥样硬化,为寻找新的药物靶点和生物标志物提供理论基础。

Abstract: The activation of Keap1-Nrf2 signaling pathway is an important mechanism for cells to resist oxidative stress. Under oxidative stress, Keap1 is affected by post-translational modification(PTM) such as glutathione, alkylation and S-sulfhydrylation, which weakens its binding to Nrf2, leading to Nrf2 accumulation, nuclear translocation and the expression and transcription of downstream detoxification and antioxidant defense proteins. The PTM of Keap1 is involved in the regulation of a variety of oxidative stress-related diseases such as cancer, Parkinson′s disease and atherosclerosis. For example, alkylation inhibits abdominal aortic aneurysm formation, methylation promotes innate resistance of breast cancer, and S-sulfhydrylation improves atherosclerosis, which provides a theoretical basis for finding new drug targets and biomarkers.

Key words: Keap1, oxidative stress, post-translational modifications, mechanism of action
