Overexpression of miR-92a-2-5p attenuated oxidative stress injury in cardiomyocytes. A Relative expression levels of miR-92a-2-5p in cardiomyocytes infected with adenovirus. n = 5 in each group. **P < 0.01. B Representative images of DCFH-DA staining in cardiomyocytes infected with adenovirus under high glucose stimulation. C-E Detection of ROS, GSH, and MDA levels in cardiomyocytes from the Ad-miR-92a-2-5p and sh-miR-92a-2-5p groups. n = 5 in each group. **P < 0.01. F Representative images of TUNEL staining in cardiomyocytes infected with adenovirus under high glucose stimulation. The red arrows indicate the TUNEL-DAPI merge signals. G Detection of TUNEL-positive cardiomyocytes in the Ad-miR-92a-2-5p and sh-miR-92a-2-5p groups. n = 5 in each group. **P < 0.01
