(Submitter supplied) Decreased mitochondrial mass and function in muscle of diabetic patients is associated with low PGC-1alpha, a transcriptional coactivator of the mitochondrial gene program. To investigate whether reduced PGC-1alpha and oxidative capacity in muscle directly contributes to age-related glucose intolerance, we compared the genetic signatures and metabolic profiles of aging mice lacking muscle PGC-1alpha. more...

(Submitter supplied) Calorie restriction (CR) is a dietary intervention that extends lifespan and healthspan in a variety of organisms. CR improves mitochondrial energy production, fuel oxidation and reactive oxygen species scavenging in skeletal muscle and other tissues, and these processes are thought to be critical to the benefits of CR. PGC-1a is a transcriptional coactivator that regulates mitochondrial function and is induced by CR. more...

(Submitter supplied) To identify mediators of obesity-linked reductions in PGC-1, we tested the effects of cellular nutrients in C2C12 myotubes. While overnight exposure to high insulin, glucose, glucosamine, or amino acids had no effect, saturated fatty acids (FA) potently reduced PGC-1a and b mRNA expression. Keywords: Nutrient Effect

Analysis of myoblasts treated with the saturated fatty acid palmitate. Muscle expression of PPAR coactivator 1 (PGC-1) is reduced in models of obesity. Palmitate decreases the expression of PGC-1. Results provide insight into the molecular basis of the link between overnutrition, obesity, and PGC-1.

(Submitter supplied) The present study examines the impact of altering energy provision on mitochondrial biogenesis in muscle cells. C2C12 myoblasts were chronically treated with supraphysiological levels of sodium pyruvate for 72 hr. Treated cells exhibited increased mitochondrial protein expression, basal respiratory rate and maximal oxidative capacity. The increase in mitochondrial biogenesis was independent of increases in PGC-1alpha and PGC-1alpha mRNA expression. more...

(Submitter supplied) The homeodomain transcription factor Prep1 was previously shown to regulate insulin sensitivity. Our aim was to study the specific role of Prep1 for the regulation of energy metabolism in skeletal muscle. Muscle specific ablation of Prep1 resulted in increased expression of respiratory chain subunits. This finding was consistent with an increase in mitochondrial enzyme activity without affecting mitochondrial volume fraction as assessed by electron microscopy. more...

(Submitter supplied) PGC-1a is a master regulator for cell mitochondrial and metabolism function. In this experiment neurons were infected with a PGC-1a/GFP adenovirus to examine what genes were upregulated by over expression. Known targets related to mitochondrial health were confirmed while new neuron specific targets were discovered.

(Submitter supplied) FOXO1, a member of the FOXO forkhead type transcription factors, is markedly up-regulated in skeletal muscle during atrophy. Previously, we created transgenic mice specifically overexpressing FOXO1 in skeletal muscle (FOXO1 Tg mice). These mice weighed less than the wildtype control mice, had a reduced skeletal muscle mass. In this study, to better understand changes in skeletal muscle during atrophy, we performed a microarray analysis of skeletal muscle in wild-type control and FOXO1 Tg mice. more...

(Submitter supplied) The peroxisome proliferator-activated receptor c coactivator 1 (PGC-1) proteins are key regulators of cellular bioenergetics and are accordingly expressed in tissues with a high energetic demand. For example, PGC-1a and PGC-1b control organ function of brown adipose tissue, heart, brain, liver and skeletal muscle. Surprisingly, despite their prominent role in the control of mitochondrial biogenesis and oxidative metabolism, expression and function of the PGC-1 coactivators in the retina, an organ with one of the highest energy demands per tissue weight, are completely unknown. more...

(Submitter supplied) The mechanistic underpinnings of the fasting response in skeletal muscle is still poorly understood. We therefore investigated the role of the transcriptional coactivator PGC-1beta (peroxisome proliferator-activated receptor gamma coactivator 1beta) in this context. To do so, the fasting response in quadriceps muscle was assessed in fed and 24 hours fasted mice and compared between wildtype and PGC-1beta muscle-specific knockout mice (both on a C57Bl6/J background). more...
