Heart disease is the number one killer of humankind mainly because the heart does not have regenerative capabilities. Our previous study indicated that oxidative stress is the main inducer of cell cycle arrest in postnatal mammalian heart muscle cells, cardiomyocytes. Our research interest is focused on why postnatal mammalian cardiomyocytes do not proliferate after injury- and age-related myocardial damage, and whether it is possible to re-awaken endogenous regenerative capacity. We utilize molecular and cellular tools and mouse genetics to understand the role of oxidative metabolism in cardiomyocyte cell cycle regulation throughout the life cycle of mammals.
