MiRNA-138抑制JNK/p38MAPK通路保护新生大鼠心肌细胞凋亡
【目的】探究miRNA-138抑制JNK/p38MAPK通路保护新生大鼠心肌细胞凋亡。【方法】收集2018年1月至12月急性心肌缺血患者全血样本33例,另招募同期体检健康者全血样本33例作对照;构建新生大鼠缺血再灌注(I/R)模型,将40只新生大鼠随机分为空白对照组(Control)、模型组(I/R model)、阴性对照组(注射无序序列,Scramble)及miRNA-138过表达组(Ad-miRNA-138),每组10只。采用qRT-PCR检测全血和心肌组织中miRNA-138、Bcl2及Bax mRNA的表达,电生理记录仪检测大鼠血流动力学指标水平,HE染色观察大鼠心肌组织病理损伤,免疫...
