The occurrence of tumors is associated with the upregulation or downregulation of certain genes. The identification of novel tumor therapies has revealed that regulation of tumor cell death can either promote or suppress the occurrence and development of tumors. Iron‑dependent lipid free oxygen radical accumulation causes tumor cells to die by ferroptosis, a form of regulated cell death. Multiple mechanisms mediate this mode of cell death, including redox homeostasis, iron metabolism, mitochondrial activity, breakdown of amino acids, lipids and sugars and epigenetic regulatory and disease‑associated signaling pathways. The present review discussed epigenetic mechanism of ferroptosis with the aim of providing novel insight for optimization of the effects of antitumor therapy.
肿瘤的发生与某些基因的上调或下调有关。新型肿瘤治疗方法的发现表明,肿瘤细胞死亡的调节既可以促进也可以抑制肿瘤的发生和发展。铁依赖性脂质自由基积累导致肿瘤细胞通过铁死亡而死亡,铁死亡是一种受调控的细胞死亡形式。多种机制介导这种细胞死亡方式,包括氧化还原平衡、铁代谢、线粒体活性、氨基酸、脂质和糖的分解以及表观遗传调控和疾病相关信号通路。本综述讨论了铁死亡的表观遗传机制,旨在为优化抗肿瘤治疗效果提供新的见解。
