Acute brown adipose tissue activation in mice (TN. vs. CL 2h)

Brown adipose tissue (BAT) is specialized for UCP1-dependent uncoupled thermogenesis. BAT is not thermogenic under an unstimulated state; whereas can be quickly activated to generate heat after sympathetic activation. CL316,243 is a specific agonist of beta3 adrenergic receptor on brown adipocytes. Treatment of CL316,243 in mice leads to potent and specific activation of BAT. The goal of this project is to characterize acute gene expression alterations in the early stage of BAT thermogenic activation.
