Ferroptosis, a recently discovered form of regulated cell death that is characterized by iron accumulation and excessive reactive oxygen species generation, has been favored by most researchers. Increasing evidence suggest that ferulic acid (FA) could exert marked effects to myocardial ischemia reperfusion (I/R) injury, although the understanding of its mol. mechanism is still limited. In our study, the myocardial I/R injury model was established to explore the relationship between I/R injury and ferroptosis. First, we successfully constructed myocardial I/R injury model with changes in ST segment, increased creatine phosphokinase, lactate dehydrogenase activities, and N-Terminal Pro Brain Natriuretic Peptide content, and a significantly larger infarct size. Then, the increased levels of the Ptgs2 mRNA, Fe2+ accumulation, and a decreased reduced glutathione/oxidized glutathione disulfide ratio were detected in ischemia-reperfusion-injured heart, which is highly consistent with ferroptosis. However, these effects were significantly improved after FA treatment. Based on these results, FA increased the activities of the antioxidant enzymes superoxide dismutase, catalase and glutathione peroxidase, decreased the malondialdehyde level, ameliorated the production of reactive oxygen species, and promoted the generation of ATP. These effects of FA are similar to those of the ferroptosis inhibitor ferrostatin-1. Upregulation of AMPKα2 and Glutathione Peroxidase 4 expression were also observed in the FA group. Compound C, a specific AMP (AMP)-activated protein kinase inhibitor, significantly blocked the protective effect of FA. These findings underlined that FA inhibits ferroptosis by upregulating the expression of AMPKα2 and serves as a cardioprotective strategy.
