MicroRNA‐7b attenuates ischemia/reperfusion‐induced H9C2 cardiomyocyte apoptosis via the hypoxia inducible factor‐1/p‐p38 pathway

MicroRNAs (miRNAs) have been shown to play crucial roles in the occurrence, development, and treatment of many cardiovascular diseases. Coronary heart disease (CAD)‐related miRNAs are still a growing research area. miR‐7b was reported to be downregulated in acute myocardial infarction (AMI) myocardium tissues. However, it remains largely unknown whether miR‐7b is involved in the pathogenesis and progression of the AMI ischemia/reperfusion (I/R) injury.
