Keap1-Nrf2通路是细胞对氧化和亲电应激的保护反应的主要调节因子。虽然转录因子Nrf2触发的细胞信号通路在正常和癌前组织中阻止癌症的发生和进展,但在完全恶性细胞中,Nrf2活性通过增加癌症化疗耐药和促进肿瘤细胞生长提供了生长优势。在这篇图表综述中,我们概述了Keap1-Nrf2通路及其在癌细胞中的失调。我们还简要总结了组成型Nrf2在癌细胞中激活的后果,以及如何在癌症基因治疗中利用这一点。
The Keap1-Nrf2 pathway is the major regulator of cytoprotective responses to oxidative and electrophilic stress. Although cell signaling pathways triggered by the transcription factor Nrf2 prevent cancer initiation and progression in normal and premalignant tissues, in fully malignant cells Nrf2 activity provides growth advantage by increasing cancer chemoresistance and enhancing tumor cell growth. In this graphical review, we provide an overview of the Keap1-Nrf2 pathway and its dysregulation in cancer cells. We also briefly summarize the consequences of constitutive Nrf2 activation in cancer cells and how this can be exploited in cancer gene therapy.
