Xia ZHONG摘要:
目的探讨缺氧诱导因子-1α(hypoxia inducible factor-1α, HIF-1α)在心肌细胞氧化损伤中的作用及其机制。方法应用过氧化氢(H2O2)构建体外心肌细胞氧化损伤模型,采用实时荧光定量聚合酶链反应(qRT-PCR)检测HIF-1α及通路相关基因如Notch胞内结构域(notch intracellular domain, NICD)、Hes-1的表达;分别采用细胞计数试剂盒-8(CCK-8)和流式细胞术检测细胞活力和细胞凋亡;采用蛋白印迹法测定蛋白水平。结果在经H2O2处理的人AC16心肌细胞中,HIF-1α表达上调;过氧化氢处理可抑制细胞活力并促进细胞凋亡;敲除HIF-1α抑制了Notch信号通路中关键成分的表达,加重了H2O2诱导的心肌细胞凋亡。结论HIF-1α可通过激活Notch通路减轻活性氧诱导的心肌细胞凋亡。
