The KEAP1-NRF2 axis is pivotal in the cellular mechanism against oxidative and electrophilic stress. NRF2, under standard conditions, undergoes proteasomal degradation mediated by the E3 ubiquitin ligase KEAP1. Stress conditions lead to KEAP1 inactivation, facilitating NRF2 stability and subsequent activation of defensive genes. NRF2 signaling anomalies are associated with cancer progression and neurodegenerative diseases. Continuous activation of the NRF2 pathway aids in the survival of cancer cells, while a deficiency in NRF2 functionality intensifies inflammation and oxidative injury in neurodegenerative disease models. Thus, the modulation of this pathway is being investigated for therapeutic applications in both cancer and neurodegenerative diseases.
KEAP1-NRF2轴在细胞对抗氧化和亲电应激的机制中起关键作用。在标准条件下,NRF2会经历由E3泛素连接酶KEAP1介导的蛋白酶体降解。应激条件会导致KEAP1失活,从而促进NRF2的稳定性以及随后防御基因的激活。NRF2信号异常与癌症进展和神经退行性疾病有关。NRF2通路的持续激活有助于癌细胞存活,而NRF2功能缺陷会加剧神经退行性疾病模型中的炎症和氧化损伤。因此,目前正在研究调节该通路在癌症和神经退行性疾病治疗中的应用。
