Ferroptosis, a relatively recently discovered type of cell death that is iron dependent and nonapoptotic, is involved in the accumulation of lipid reactive oxygen species (ROS), and has been shown to serve a vital role in various pathological processes, including those underlying neurodegeneration, ischemic reperfusion injury, acute organ injury, and in particular, tumor biology. Emerging evidence has highlighted the roles of ferroptosis in the development and resistance to chemoradiotherapy in cancer. Recently, an increasing number of studies have shown that non‑coding RNAs modulate the process of ferroptotic cell death, and this has further highlighted the potential of regulation of ferroptosis as a means of cancer management. Although these studies have highlighted the critical role of ferroptosis in cancer therapeutics, the roles of ferroptosis induced by non‑coding RNAs in cancer development remain unclear. Herein, the current body of knowledge of ferroptosis in cancer is summarized and an overview of the mechanisms of ferroptosis and the functions of non‑coding RNAs in regulating ferroptotic cell death are discussed. The future status of ferroptosis in cancer management is deliberated and strategies for treatment of therapy‑resistant cancers are discussed.
铁死亡是一种相对较新发现的细胞死亡方式,它依赖于铁并且是非凋亡性的,与脂质活性氧(ROS)的积累有关,并被证明在多种病理过程中发挥重要作用,包括神经退行性变、缺血再灌注损伤、急性器官损伤,特别是肿瘤生物学。新出现的证据强调了铁死亡在癌症的化学放射治疗的发展和耐药性中的作用。最近,越来越多的研究表明,非编码 RNA 调节铁死亡细胞死亡的过程,这进一步强调了调节铁死亡作为癌症管理手段的潜力。尽管这些研究强调了铁死亡在癌症治疗中的关键作用,但非编码 RNA 诱导的铁死亡在癌症发展中的作用尚不清楚。本文总结了铁死亡在癌症中的研究现状,综述了铁死亡的机制以及非编码 RNA 调节铁死亡细胞死亡的功能,讨论了铁死亡在癌症管理中的未来地位,并探讨了治疗耐药性癌症的策略。
