Cisplatin, a chemotherapeutic drug, can result in acute kidney injury (AKI). Currently, there are no effective prevention methods. An incomplete understanding of the pathogenesis of AKI is a major barrier to the development of effective therapies. Metabolism reprogramming shift to glycolysis was involved in AKI pathogenesis. Glycolysis results in the pyruvate production. The mitochondrial pyruvate carrier (MPC) conveys cytosol pyruvate into mitochondria, promoting the tricarboxylic acid cycle. In this current study, we found a reduction in MPC2 expression in mice and cultured HK2 cells with cisplatin-induced AKI. MPC2 overexpression attenuated cisplatin-mediated nephrotoxicity both and o via restoring pyruvate metabolism and mitochondrial function. Knockdown of MPC2 reversed this effect. Furthermore, artemether, an MPC2 potential activator, could mitigate AKI via regulating MPC2-mediated pyruvate metabolism. Our findings revealed that MPC2-pyruvate metabolism axis was a promising strategy to alleviate AKI induced by cisplatin.
