摘要:

核因子E2相关因子2(nuclear factor E2-related factor 2,Nrf2)是细胞抗氧化反应的主要调节因子,其活性由负性调节蛋白Kelch样ECH关联蛋白1(Kelch-like-ECH-associated protein 1, Keap1)精确调控。Nrf2的抗氧化作用通过与氧化还原敏感蛋白Keap1的相互作用而被抑制。Keap1/Nrf2转录活性的失调与多种疾病的发病有关,Keap1/Nrf2轴已成为细胞内稳态最重要的调节因子,在许多慢性疾病的发生和发展中起着重要作用,Nrf2还可通过诱导肿瘤细胞抗氧化应激而介导耐药。研究发现,非小细胞肺癌(non‐small cell lung cancer, NSCLC)中的Keap1/Nrf2突变与抗肿瘤治疗(包括化疗、放疗、靶向治疗)的抵抗有关,对免疫治疗的影响暂未明确。基于Nrf2在肿瘤发生、发展的过程中呈现的双重作用,靶向干预Nrf2或许可早期预防高危人群肿瘤的发生,还可增强抗肿瘤治疗效应。本文综述了Keap1/Nrf2通路改变在NSCLC临床研究中的进展,提示监测Keap1/Nrf2通路的改变可能是预测临床预后和治疗抵抗的重要策略之一。

Abstract:

Nuclear factor E2 related factor 2 (Nrf2) is the main regulator of cellular antioxidant response, and its activity is precisely regulated by the negative regulatory protein Keap1 (Kelch-like-ECH-associated protein 1). The antioxidant effect of Nrf2 is inhibited by interaction with redox sensitive protein Keap1. The imbalance of Keap1/Nrf2 transcriptional activity is related to the pathogenesis of many diseases. Keap1/Nrf2 axis has become the most important regulator of intracellular homeostasis and plays an important role in the occurrence and development of many chronic diseases. Nrf2 can also mediate drug resistance by inducing antioxidant stress in tumor cells. Several studies have found that Keap1/Nrf2 mutation in NSCLC is related to the resistance of antitumor therapy (including chemotherapy, radiotherapy and targeted therapy), and its impact on immunotherapy is not clear. Based on the dual role of Nrf2 in the process of tumor occurrence and development, targeted intervention of Nrf2 may not only prevent the occurrence of tumors in high-risk groups in the early stage, but also enhance the effect of anti-tumor treatment. This paper reviews the progress of Keap1/Nrf2 pathway changes in clinical research of NSCLC, suggesting that monitoring the changes of Keap1/Nrf2 pathway may be one of the important strategies to predict clinical prognosis and treatment resistance.
