The aim of this study was to explain the effect and mechanisms of miRNA-30-3p in myocardial ischemia-induced cell apoptosis in vitro and in?vivo studies. In the cell experiment, the H9C2 cells were?divided into the normal control (NC), and the model, miRNA, and miRNA?+?phosphatidylinositol 3-kinase (PI3K) inhibitor groups. The cell survival rates of the different?groups were measured with?the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium assay kit;?the lactate dehydrogenase (LDH), malondialdehyde (MDA) content, and?superoxidedimutase (SOD) activity in the bathing medium were?assayed for the evaluation of myocardial cell injury. The cell apoptosis rate of ... More
