Objectives
1 Does overexpression of human SIRT1 in endothelial cells facilitate the metabolism of BCAA (in particular leucine) by modulating the 24-hour circadian expressions of key enzymes in peripheral tissues? 2 Does timely enhanced leucine metabolism contribute to the 24-hour oscillations of body temperature and arterial blood pressure in mice with endothelial overexpression of human SIRT1? 3 How does SIRT1 expression and activity oscillate with leucine metabolism and/or body temperature changes in peripheral organs?
