摘要:

铁死亡(ferroptosis)是一种铁和脂质过氧化依赖性的程序性死亡方式,触发铁死亡的必要条件是细胞内活性氧物质堆积到致死量。由脂质过氧化反应产生的脂质活性氧会作用于细胞膜上的脂质分子,导致脂质过氧化和膜损伤,因此脂质过氧化是铁死亡的显著特征。长链酯酰辅酶A合成酶4(long-chain acyl-CoA synthetase 4, ACSL4)在调节脂质代谢方面具有关键作用,其主要功能是将多不饱和脂肪酸酯化并插入膜磷脂中,从而加速脂质过氧化的发生并推动铁死亡。ACSL4介导的铁死亡主要受到转录、转录后和翻译后水平上的调控影响,在脂质过氧化依赖性的疾病中发挥着重要作用。本文旨在介绍铁死亡的发生机制,重点阐述了ACSL4受到的上游调控从而介导铁死亡的机制,为研究ACSL4介导铁死亡机制提供理论依据。

Abstract:

Ferroptosis is an iron and lipid peroxidation-dependent mode of programmed death, and it is triggered when the accumulation of reactive oxygen species reaches a lethal level within the cell. Lipid reactive oxygen species produced by lipid peroxidation act on lipid molecules on cell membranes, resulting in lipid peroxidation and membrane damage, so lipid peroxidation is a prominent feature of ferroptosis. Long-chain acyl-CoA synthetase 4 (ACSL4) plays a crucial role in regulating lipid metabolism, primarily by esterifying polyunsaturated fatty acids and incorporating them into membrane phospholipids, thereby accelerating lipid peroxidation and driving ferroptosis. ACSL4-mediated ferroptosis is mainly regulated at transcriptional, post-transcriptional, and post-translational levels and plays an important role in lipid peroxidation-dependent diseases. The purpose of this study is to elucidate the mechanisms underlying ferroptosis, focusing on the upstream regulation of ACSL4 and consequently mechanism of ferroptosis, providing a theoretical basis for investigation into the mechanisms of ACSL4-mediated ferroptosis.

Key words: long-chain acyl-CoA synthetase 4, ferroptosis, lipid peroxidation, upstream regulation mechanism
