The potential protective effect of sirtuin enzymes in age-related diseases, including cardiovascular diseases, remains an area of intense investigation. Now, researchers has determined that sirtuin 1 (SIRT1) and sirtuin 3 (SIRT3) levels decline in aging hearts, disrupting the ability of cardiac muscle cells (cardiomyocytes) to contract in response to ischemia-reperfusion injury.
