摘要
铁坏死是一种新的细胞死亡方式,受到细胞内多条信号通路严密调节,包括铁稳态调节途径、胱氨酸谷氨酸反向转运体途径和电压依赖性阴离子通道途径等。虽然有证据表明铁坏死参与了心肌缺血/再灌注损伤,但仍有许多问题尚待解决,如铁坏死主要发生在缺血/再灌注的哪个阶段？铁坏死的发生是否必须有铁离子参与？阐明铁坏死的发生过程和机制对于寻找防治心肌缺血/再灌注损伤新药具有重要意义。
Ferroptosis is a novel type of cell death,which is closely modulated by multiple signaling transduction pathways including iron homeostasis pathway,cystine/glutamate transporter（ System XC-） pathway and voltage-dependent anion channel（ VDAC） pathway. Although there is evidence that ferroptosis contributes to myocardial ischemia/reperfusion injury,many questions remain to be solved,such as which stage ferroptosis mainly appear following myocardial ischemia/reperfusion？ Is it a necessary condition for the involvement of iron in ferroptosis？ It is of significance for seeking novel drugs to protect the heart against ischemia/reperfusion injury once the mechanisms for ferroptosis are elucidated.
