铁死亡在心肌病中的研究进展

Research Progress of Iron Death in Cardiomyopathy

心肌病是一组具有多种特定表型的异质性心肌疾病,严重者会引起心血管性死亡或进行性心力衰竭。由于这类疾病的严重性和复杂性,寻找新的调节机制来防治心肌病显得尤为紧迫。铁死亡是一种不同于其他形式的铁依赖性的细胞程序性死亡形式,其特征是铁依赖性脂质过氧化物的积累。研究表明,铁死亡可通过不同的信号通路参与心肌病的发生和进展。因此通过靶向调控铁死亡是防治心肌病的一种新策略。就铁死亡的发生机制及其在心肌病中的重要作用进行综述,以期寻找铁死亡与心肌病之间的潜在联系,为今后各种心肌病的治疗提供更多思路。

Cardiomyopathy is a group of heterogeneous myocardial diseases with a variety of specific phenotypes that can lead to cardiovascular death or progressive heart failure in severe cases.Because of the severity and complexity of these diseases,the search for new regulatory mechanisms to prevent and treat cardiomyopathy is particularly urgent.Iron death is a form of programmed cell death that differs from other forms of iron dependence and is characterized by the accumulation of iron-dependent lipid peroxides.Studies have shown that iron death can be involved in the occurrence and progression of cardiomyopathy through different signaling pathways.Therefore,targeted regulation of iron death is a new strategy to prevent cardiomyopathy.In this paper,the mechanism of iron death and its important role in cardiomyopathy were reviewed to find the potential relationship between iron death and cardiomyopathy and provide more ideas for the treatment of various cardiomyopathies in the future.
