Effect of lncRNA KCNQ1OT1 on MI/RI (n = 3). A-D: Detection of the level of lncRNA-KCNQ1OT1, miR-377-3p, and HMOX1 by RT‒qPCR. E: Flow cytometry was used to detect ROS levels. F: MitoSOX Red probe was used to measure mitochondrial ROS levels (scale bar = 100 μm). G-H: Oxidative stress marker kits were utilized to evaluate SOD and MDA levels. Compared with the NC group, ^***P < 0.001; compared with the H/R+si-NC or H/R + si-KCNQ1OT1 group, ^# P < 0.05, ^## P < 0.01 and ^### P < 0.001
