谷胱甘肽过氧化物酶4/谷胱甘肽铁死亡防御系统在三阴性乳腺癌治疗中的作用研究进展

Research progress of glutathione peroxidase 4/glutathione ferroptosis defense system in the treatment of triple-negative breast cancer

铁死亡是一种以脂质过氧化物为核心的细胞死亡方式,细胞可依赖谷胱甘肽过氧化物酶4(GPX4)/谷胱甘肽(GSH)抗氧化系统降低铁死亡敏感性。三阴性乳腺癌(TNBC)细胞较正常细胞更依赖胞内抗氧化机制,以GPX4/GSH系统为基础的铁死亡诱导表现出显著的治疗TNBC前景。本文综述近年来以GPX4/GSH为背景的铁死亡治疗TNBC研究成果,以期为TNBC的临床治疗提供参考。

Ferroptosis is a way of cell death with lipid peroxides as the core.Cells can reduce ferroptosis sensitivity by relying on glutathione peroxidase 4(GPX4)/glutathione(GSH)antioxidant systems.Triple-negative breast cancer(TNBC)cells are more dependent on the intracellular antioxidant mechanism than normal cells,thus induction of ferroptosis based on the GPX4/GSH system has shown bright anti-TNBC prospects.This paper reviews the recent research on TNBC treatment with ferroptosis in the background of GPX4/GSH,in order to provide references for the clinical treatment of TNBC.
