(Submitter supplied) Skeletal muscle tissue shows an extraordinary cellular plasticity, but the underlying molecular mechanisms are still poorly understood. Here we use a combination of experimental and computational approaches to unravel the complex transcriptional network of muscle cell plasticity centered on the peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), a regulatory nexus in endurance training adaptation. more...

(Submitter supplied) The peroxisome proliferator-activated receptor γ co-activator 1α (PGC-1α) coordinates the transcriptional network response to promote an improved endurance capacity in skeletal muscle, e.g. by co-activating the estrogen-related receptor α (ERRα) in the regulation of oxidative substrate metabolism. Despite a close functional relationship, the interaction between these two proteins has not been studied on a genomic level. more...

(Submitter supplied) Endurance and resistance exercise training induce specific and profound changes in the skeletal muscle transcriptome. PGC-1a; coactivators are not only among the genes differentially induced by distinct training methods, but also participate in the ensuing signaling cascades that allow skeletal muscle to adapt to each type of exercise. While endurance training preferentially induces PGC-1a1 expression, resistance exercise activates the expression of PGC-1a2, a3, and a4. more...

(Submitter supplied) In the present study we have studied the mechanistic and functional aspects of NCoR1 function in mouse skeletal muscle. NCoR1 muscle-specific knockout mice exhibited an increased oxidative metabolism. Global gene expression analysis revealed a high overlap between the effects of NCoR1 deletion and peroxisome proliferator-activated receptor (PPAR) gamma coactivator 1alpha (PGC-1alpha) overexpression on oxidative metabolism in skeletal muscle. more...

(Submitter supplied) Although PGC 1α is well-established as a transcriptional coactivator for the metabolic adaptation of mammalian cells to diverse physiological stresses, its molecular dynamics at the start and during gene transcription are incompletely understood. Previously, we defined a CBP80-binding motif (CBM) within PGC 1α that binds CBP80 at the 5′-cap of nascent transcripts deriving from PGC 1α-responsive genes. 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) PGC-1alpha has been proposed to couple gene transcription and RNA processing via SR-rich domains and an RNA recognition motif located at the C-terminal domain (CTD). However, the full extent by which the CTD of PGC-1alpha regulates its function in gene expression and RNA processing remains largely unknown. Here, we used RNA-seq to evaluate the effects of CTD deletion (dCTD) on PGC-1alpha function. We found that deletion of the CTD of PGC-1alpha virtually abolished its effects on transcriptome remodeling and the resulting increase in oxidative capacity in skeletal muscle cells. more...
