【 摘 要 】

Mitochondrial function is paramount to energy homeostasis, metabolism, signaling, and apoptosis in cells. Mitochondrial complex V (ATP synthase), a molecular motor, is the ultimate ATP generator and a key determinant of mitochondrial function. ATP synthase catalyzes the final coupling step of oxidative phosphorylation to supply energy in the form of ATP. Alterations at this step will crucially impact mitochondrial respiration and hence cardiac performance. It is well established that cardiac contractility is strongly dependent on the mitochondria, and that myocardial ATP depletion is a key feature of heart failure. ATP synthase dysfunction can cause and exacerbate human diseases, such as cardiomyopathy and heart failure. While ATP synthase has been extensively studied, essential questions related to how the regulation of ATP synthase determines energy metabolism in the heart linger and therapies targeting this important mechanism remain scarce. This review will visit the main findings, identify unsolved issues and provide insights into potential future perspectives related to the regulation of ATP synthase and cardiac pathophysiology.
