铁死亡是一种依赖铁过载及细胞内活性氧诱导脂质过氧化代谢失调引起的新型细胞死亡形式。铁死亡过程中伴有活性氧成分不仅能够直接杀伤肿瘤细胞,还可以改善肿瘤微环境,克服乏氧肿瘤细胞引起的放疗抵抗,增强放射敏感性。因此,调节放疗过程中细胞调节性铁死亡,为肿瘤放射治疗和辐射防护提供了一种潜在的新策略。本文通过系统的文献回顾,介绍铁死亡的发生机制,分析铁死亡在放疗增敏、放疗抵抗和放疗辐射损伤中的最新研究进展,进一步展望铁死亡在放疗增敏、辐射损伤防护及放射免疫联合治疗中的应用和研究前景,有助于研究者更好地了解铁死亡在肿瘤放射治疗中的关键作用。

Radioresistance and radiation damage are the difficult problem that need to be solved urgently in cancer radiotherapy. Ferroptosis is a novel type of cell death induced by iron overload and lipid peroxidation metabolic imbalance caused by the enhancement of intracellular reactive oxygen species (ROS) . ROS induced by ferroptosis can not only lead to cellular damage directly, but also improve the hypoxic microenvironment of tumors and sensitize radiotherapy. Ferroptosis plays an important role in inhibiting tumor proliferation and enhancing radiosensitivity, providing a potential new strategy for improving efficacy of radiotherapy. Here, we reviewed the research progress of ferroptosis and made a prospect of its application in radiotherapy.
