Song et al. stated that miR-126 expression may be induced by HIF-1α in endothelial cells after myocardial infarction, which promotes angiogenesis in peri-infarct areas through regulation of the activity of the phosphatidylinositol 3-kinase/protein kinase B pathway (PI3K/AKT) [42]. This evidence concerns the gene AKT1 and myocardial infarction.
