In vitro study | Trimetazidine upregulates the expression of miR-21, and miR12 targets PTEN and promotes PI3K signaling pathway, thus hindering the apoptotic effect brought about by hypoxia/reperfusion. |
In vivo study | In the heart of wild-type C57BL/6J mice, treatment with TMZ(Trimetazidine) reduced the area of myocardial infarction. Both AMPK and ERK signaling pathways mediate and participate in the Myocardial Protection of TMZ against ischemic injury of the heart. Trimetazidine converts fatty acid oxidation metabolism to glucose oxidation metabolism and improves the contractile function of cardiomyocytes under hypoxic conditions. |
