The transcriptional coactivator peroxisome proliferator-activated receptor-gamma coactivator 1 alpha (PGC-1α) is a chief activator of mitochondrial and metabolic programs and protects against atrophy in skeletal muscle (skm). Here we tested whether PGC-1α overexpression could restructure the transcriptome and metabolism of primary cultured human skm cells, which display a phenotype that resembl...

OBJECTIVE Cellular senescence influences organismal aging and increases predisposition to age-related diseases, in particular cardiovascular disease, a leading cause of death and disability worldwide. Peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) is a master regulator of mitochondrial biogenesis and function, oxidative stress, and insulin resistance. Senescence is associa...

Terada, Shin, and Izumi Tabata. Effects of acute bouts of running and swimming exercise on PGC-1 protein expression in rat epitrochlearis and soleus muscle. Am J Physiol Endocrinol Metab 286: E208–E216, 2004. First published October 21, 2003; 10.1152/ ajpendo.00051.2003.—The purpose of this study was to elucidate the mechanisms underlying low-intensity exercise-induced peroxisome proliferator-a...

The present study investigated whether exercise induces the expression of PGC-1α splice variants in human skeletal muscle and the possible influence of metabolic perturbation on this response. The subjects exercised one leg for 45 min with restricted blood flow (R-leg), followed by 45 min of exercise using the other leg at the same absolute workload but with normal blood flow (NR-leg). This isc...

The transcriptional coactivator peroxisome proliferator activated receptor gamma coactivator 1alpha (PGC-1alpha) can activate a number of transcription factors to regulate mitochondrial biogenesis and cell-specific responses to cold, fasting, and exercise. Recent studies indicate that PGC-1alpha knockout mice exhibit behavioral abnormalities and progressive vacuolization in various brain region...

Since the identification of the transcriptional co-activator peroxisome proliferator activated receptor y co-activator (PGC)-1α as a factor interacting with PPARy in brown adipose tissue (BAT) (12), it has become clear that PGC-1α plays important roles in regulating several cellular processes in many different tissues (10) including mitochondrial biogenesis in skeletal muscle (1; 9) Previously,...

Peroxisome proliferator-activated receptor (PPAR) γ coactivator 1α (PGC-1α) is a coactivator of various nuclear receptors and other transcription factors whose expression increases in the skeletal muscle during exercise. We have previously made transgenic mice overexpressing PGC-1α in the skeletal muscle (PGC-1α-Tg mice). PGC-1α upregulates the expression of genes associated with red fibers, mi...

BACKGROUND Thiazolidinediones, a family of insulin-sensitizing drugs commonly used to treat type 2 diabetes, are thought to exert their effects in part by promoting mitochondrial biogenesis in white adipose tissue through the transcriptional coactivator PGC-1α (Peroxisome Proliferator-Activated Receptor γ Coactivator-1α). METHODOLOGY/PRINCIPAL FINDINGS To assess the role of PGC-1α in the cont...

OBJECTIVE The peroxisome proliferator-activated receptor-γ coactivator-1α1 (PGC-1α1) regulates genes involved in energy metabolism. Increasing adipose tissue energy expenditure through PGC-1α1 activation is potentially beneficial for systemic metabolism. Pharmacological PGC-1α1 activators could be valuable tools in the fight against obesity and metabolic disease. Finding such compounds has been...

Metabolic disease is a leading cause of death worldwide, and obesity, a central risk factor, is reaching epidemic proportions. Energy expenditure and brown adipose tissue (BAT) thermogenesis are implicated in metabolic disease, and it is becoming evident that impaired BAT activity is regulated by gene/environment interactions. Peroxisome proliferator-activated receptor γ coactivator 1α (Pgc-1α)...
