A mitochondrial mark for heart failure

Current therapies for heart failure vary depending on the root cause and stage of the disease. Acin-Perez et al. studied the molecular link between mitochondrial dysfunction and heart failure, focusing on OMA1, a protease involved in mitochondrial inner membrane remodeling and cytochrome c release. Using three mouse models of heart failure, they found that cardiomyocytes were protected from mitochondrial reactive oxygen species–induced cell death when OMA1 was ablated. OMA1 could be a therapeutic target for heart failure.
