Ischaemia of the heart, brain and limbs is a leading cause of morbidity and mortality worldwide. Hypoxia stimulates the secretion of vascular endothelial growth factor (VEGF) and other angiogenic factors, leading to neovascularization and protection against ischaemic injury. Here we show that the transcriptional coactivator PGC-1alpha(More)
Binding to receptors in the cell nucleus is crucial for the action of lipophilic hormones and ligands. PPAR-gamma (for peroxisome proliferator-activated receptor) is a nuclear hormone receptor that mediates adipocyte differentiation and modulates insulin sensitivity, cell proliferation and inflammatory processes. PPAR-gamma ligands have been implicated in(More)
The association between obesity and diabetes supports an endocrine role for the adipocyte in maintaining glucose homeostasis. Here we report that mice lacking the adipocyte hormone resistin exhibit low blood glucose levels after fasting, due to reduced hepatic glucose production. This is partly mediated by activation of adenosine monophosphate-activated(More)
Estrogen-related receptor gamma (ERRgamma) regulates the perinatal switch to oxidative metabolism in the myocardium. We wanted to understand the significance of induction of ERRgamma expression in skeletal muscle by exercise. Muscle-specific VP16ERRgamma transgenic mice demonstrated an increase in exercise capacity, mitochondrial enzyme activity, and(More)
The mechanisms by which peroxisome proliferators are able to regulate metabolic processes such as fat metabolism, while at the same time creating an environment for the development of hepatocellular carcinomas, is a central issue in the non-genotoxic carcinogenesis field. The convergence of two members of the steroid receptor family (peroxisome(More)
