This study was conducted with aims of investigating how microRNA-212 (miR-212) and the inhibition of aquaporin-9 (AQP9) through the activation of the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) signaling pathway plays a role in the prevention of MI.
Herein, we sought to correlate eNOS phosphorylation status with cardiomyocyte survival and we investigated the contribution of the proline-rich tyrosine kinase 2 (PYK2)/eNOS axis to the regulation of myocardial infarct size in vivo.
The knockout MI group had elevated levels of glycogen synthase kinase (GSK) 3β and decreased phosphatidylinositol 3-kinase (PI3K), phosphorylated serine/threonine protein kinase B (p-Akt), and cyclin D1, compared with the wildtype MI group.
