摘　　要：胃癌是我国人口死亡的主要原因之一,近年来确诊为早期胃癌的患者数量逐年上升,然而肿瘤细胞耐药性的产生严重限制了手术和化学治疗的效果,极有必要探索胃癌治疗的新靶点。铁死亡是一种铁依赖性细胞程序性死亡方式,其显著特征是细胞内脂质过氧化。胃癌细胞对细胞内铁代谢水平非常敏感,铁死亡在胃癌的发生、进展、治疗及耐药机制中发挥着至关重要的作用。胃癌细胞内铁死亡相关基因和非编码RNA与胃癌转移、耐药和预后密切相关,近年来关于铁死亡对胃癌细胞增殖的调节作用研究已获得一定的进展,因此,靶向铁死亡可能是胃癌的有效治疗策略。本文通过阐述铁死亡在胃癌细胞增殖、侵袭、转移及耐药机制中的作用,总结与铁死亡相关的靶点基因,并对靶向调节铁死亡在胃癌治疗中的前景进行展望。Gastric cancer(GC)is one of the main causes of death in China.Recently,the patients diagnosed with early GC has increased year by year.However,drug resistance has seriously limited the effects of surgery and chemotherapy.Therefore,it is urgent to explore new therapeutic targets for GC.Ferroptosis is an iron-dependent programmed cell death,and it is characterized by intracellular lipid peroxidation.GC cells are very sensitive to the level of intracellular iron metabolism.Ferroptosis plays an important role in the development,progression,treatment and drug resistance of GC.Ferroptosis-related genes and non-coding RNAs in GC cells are closely related to metastasis,drug resistance and prognosis of GC.In recent years,research on the regulatory effect of ferroptosis on the proliferation of GC cells has made some progress,and targeted ferroptosis may be an effective treatment for GC.This article describes the role of ferroptosis in the proliferation,invasion,metastasis and drug resistance of GC cells,summarizes the target genes related to ferroptosis,and prospects the application of targeted regulation of ferroptosis in the treatment of GC.
