Reduced expression of miR-92a-2-5p was detected in cardiomyocyte oxidative stress injury. A Representative images of DCFH-DA staining of cardiomyocytes stimulated by high glucose. B-D Detection of ROS, GSH, and MDA levels in cardiomyocytes stimulated with high glucose. n = 5 in each group. **P < 0.01. E Representative images of TUNEL staining in cardiomyocytes stimulated by high glucose. The red arrows indicate the TUNEL-DAPI merge signals. F Detection of TUNEL-positive cardiomyocytes after high glucose stimulation. n = 5 in each group. **P < 0.01. G Relative expression levels of oxidative stress-responsive miRNAs in high glucose-stimulated cardiomyocytes. n = 5 in each group. ** P < 0.01 vs. control group
