MiR-742-3p relieved hypoxia-induced H9c2 cell injury. H9c2 cells were transfected with or without miR-NC (50 nM) or miR-742-3p mimic (50 nM), and then treated with hypoxia. Untreated H9c2 cells were used as control. Cell viability, migrated and invaded cell numbers, and cell apoptosis rate were measured using CCK8 assay (A), transwell assay (B, C) and flow cytometry (D). E, F The protein levels of Bcl-2, Bax and Cleaved-caspase 3 were determined using WB analysis. All experiments were repeated three times. ***P < 0.001
