چکیده انگلیسی
This article investigated the effects of pramipexole on myocardial ischemia reperfusion (I/R) injury and its underlying mechanisms. We utilized an in vivo mouse model of myocardial I/R injury and an in vitro H9c2 cell model of hypoxia/reoxygenation (H/R) injury. Pramipexole pretreatment in male C57BL/6 mice significantly reduced the myocardial infarction size, decreased the CK and LDH activities at the serum level and enhanced autophagy. In the in vitro study, the pramipexole treatment significantly elevated the survival rate, decreased the LDH activity, reduced ROS generation and restored the ÎΨm in H9C2 cells during H/R. Additionally, its use could increase the autophagy flux level in H9c2 cells. The underlying mechanisms were determined by measuring the expression of the autophagic protein levels. These results further indicated that pramipexole treatment modulated H/R-induced autophagy via an AMPK-dependent pathway. All of these data indicate that pramipexole exerted protective effects against myocardial I/R injury and enhanced autophagy in part through the AMPK-mediated pathway.
