Project title: Inhibition of mitochondrial sodium/calcium exchanger, NCLX, as a therapeutic strategy to reduce myocardial ischaemia-reperfusion injury during myocardial infarction (project funded by Instituto de Salud Carlos III, Ministerio de Ciencia, Innovación y Universidades). Project Summary: o Background: A key role for the mitochondrial sodium/calcium exchanger, NCLX, in reactive oxygen species (ROS) production during ischemia has been recently unveiled in endothelial and neuronal cells. Preliminary results show that NCLX inhibition can also abolish ROS production during reperfusion and reduces infarction in a mouse model of stroke. As ischemia-reperfusion (IR) injury during acute myocardial infarction is driven by ROS production and oxidative damage, we want to address whether the same mechanism operates in cardiomyocytes, and the therapeutic potential of NCLX inhibition. o Objectives: (1) To characterize the role of NCLX in ROS production during IR in cardiomyocytes (2) to evaluate if the application of novel NCLX inhibitors would constitute a promising therapeutic approach to reduce IR injury. o Methods: We will perform a detailed molecular study (superoxide production, cell viability, mitochondrial pH and oxygen consumption) of the effects of mitochondrial sodium-calcium exchange during IR, to understand the molecular pathways leading to ROS production. We will use isolated hearts, in vivo rodent and pig models of myocardial infarction, and cardiomyocytes isolated from human atrial samples to test the usefulness of novel NCLX inhibitors to attenuate IR injury. We expect that inhibition of NCLX may reduce myocardial infarct size by attenuating mitochondrial ROS production. What can we offer?
