MiR-320 promoted cardiomyocyte apoptosis induced by H/R and enhanced the loss of the mitochondrial membrane potential. a The relative levels of miR-320 normalized to U6 in H9c2 cells subjected to H/R were detected after the cells were transfected with miR-320, anti-miR-320 or the respective control using qRT-PCR. b Flow cytometry was used to investigate the apoptosis of H9c2 cells. The corresponding representative micrographs are located on the left. c The effect of miR-320 on the mitochondrial membrane potential in cardiomyocytes was detected. *P < 0.05
