Abstract
Acute myocardial infarction (MI) is a global issue with high incidence and mortality. Rapid recovery of the blocked coronary flow represents the most effective strategy to reduce the size of myocardial infarction and improve the cardiac function. The aim of the study is to investigate the effects of curcumin in attenuates myocardial ischemia and reperfusion-induced proinflammatory response through activation of the Nrf-2/HO-1 signaling pathway. Wild‐type C57BL/6J mice (male, 8–10 weeks old) were used and murine myocardial ischemia and reperfusion injury (IRI) model was conducted, cardiac function was evaluated by echocardiography. Infarct size measurement, cardiac troponin-I assays, oxidative stress analysis and histopathological analyzed. The resulted data showed that curcumin alleviates myocardial inflammatory responses and oxidative stress during myocardial IRI. Also, curcumin reduces cell apoptosis induced by myocardial IRI, curcumin reduces cell apoptosis induced by myocardial IRI and activates the Nrf-2/HO-1 signaling pathway during myocardial. Inconclusion, this study demonstrates that curcumin attenuates myocardial IRI by inhibiting proinflammatory cytokines through a mechanism that may be related to activation of the Nrf-2/HO-1 signaling pathway.
