铁死亡是一种铁依赖性、非凋亡形式的受调节细胞死亡,由氧化还原和抗氧化机制受损引发,并通过有毒脂质过氧化物的积累而传播。一系列实验研究表明铁死亡具有肿瘤抑制作用。对铁死亡的敏感性或抵抗力可以通过细胞自主和非细胞自主代谢机制来调节。这包括铁死亡的作用超出了肿瘤细胞本身,由肿瘤微环境的成分(包括 T 细胞和其他免疫细胞)介导。在此,我们回顾了促进癌细胞对铁死亡敏感性的内在和外在因素,并通过描述充分利用铁死亡药物作为癌症治疗选择的方法得出结论。
Ferroptosis is an iron-dependent, nonapoptotic form of regulated cell death triggered by impaired redox and antioxidant machinery and propagated by the accumulation of toxic lipid peroxides. A compendium of experimental studies suggests that ferroptosis is tumor-suppressive. Sensitivity or resistance to ferroptosis can be regulated by cell-autonomous and non-cell-autonomous metabolic mechanisms. This includes a role for ferroptosis that extends beyond the tumor cells themselves, mediated by components of the tumor microenvironment, including T cells and other immune cells. Herein, we review the intrinsic and extrinsic factors that promote the sensitivity of cancer cells to ferroptosis and conclude by describing approaches to harness the full utility of ferroptotic agents as therapeutic options for cancer therapy.
