Gene expression profiles in brown fat tissues of wild type (WT) and Tsku knock out mice

Mice lacking TSKU exhibited elevated core body temperature and were unable to adequately suppress energy expenditure during starvation, leading to greater body weight loss. Tsku null mice were strongly resistant to diet-induced obesity and its associated metabolic disorders, including insulin resistance and hepatic steatosis. This metabolic phenotype was associated with sympathetic activation and enhanced brown fat thermogenesis. Here we used microarrays to uncover the metabolic pathways relevant to the phenotype induced by Tsku deficiency.
