Upregulation of miR-22 contributes to myocardial I/R injury.
MiR-22 causes mitochondrial dysfunction and cell injury by targeting Sirt1/ PGC1α.
H/R-induced upregulation of miR-22 may be due to ROS-induced activation of p53.
The therapeutic potential of miR-22 inhibition for acute myocardial I/R injury.
