(Submitter supplied) Secreted proteins serve pivotal roles in the development of multicellular organisms, acting as structural matrix, extracellular enzymes and signal molecules. In this study we demonstrate, unexpectedly, that PGC-1α, a critical transcriptional co-activator of metabolic gene expression, functions to down-regulate expression of diverse genes encoding secreted molecules and extracellular matrix (ECM) components to modulate the secretome. more...

(Submitter supplied) Cell adhesion plays an important role in determining cell shape and function in a variety of physiological and pathophysiological conditions. While links between metabolism and cell adhesion were previously suggested, the exact context and molecular details of such a cross-talk remain incompletely understood. Our study shows that PGC-1alpha, a pivotal transcriptional co-activator of metabolic gene expression, acts to inhibit expression of cell adhesion genes. more...

(Submitter supplied) We examined global gene expression patterns in response to PGC-1 expression in cells derived from liver or muscle. As our study revealed regulation of HSF1 by PGC-1alpha, in some experiments we knocked-down HSF1 using siRNAs in addition to inducing PGC-1alpha expression.

(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) The nuclear receptor peroxisome proliferator-activated receptor alpha (PPARα) regulates responses to chemical or physical stress in part by altering expression of genes involved in proteome maintenance. Many of these genes are also transcriptionally regulated by heat shock (HS) through activation by HS factor-1 (HSF1). We hypothesized that there are interactions on a genetic level between PPARα and the HS response mediated by HSF1. more...

(Submitter supplied) The β-adrenergic receptor signaling pathway is a major component of adaptive thermogenesis in brown and white adipose tissue during cold acclimation. The β-AR activation highly induces transcriptional coactivator PGC-1α and its splice variant N-terminal (NT)-PGC-1α, promoting the transcription program of mitochondrial biogenesis and thermogenesis. In the present study, we evaluated the role of NT-PGC-1α in brown adipocyte energy metabolism by genome-wide profiling of NT-PGC-1α-responsive genes. more...

(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...

(Submitter supplied) The transcriptional regulator peroxisome proliferator activated receptor gamma coactivator 1A (PGC-1α), encoded by PPARGC1A, has been linked to neurodegenerative diseases. Recently discovered CNS-specific PPARGC1A transcripts are initiated far upstream of the reference promoter, spliced to exon 2 of the reference gene, and are more abundant than reference gene transcripts in post-mortem human brain samples. more...

(Submitter supplied) The current view of cellular transformation and cancer progression supports the notion that cancer cells must reprogram their metabolism in order to survive and progress in different microenvironments. Master co-regulators of metabolism orchestrate the modulation of multiple metabolic pathways through transcriptional programs, and hence constitute a probabilistically parsimonious mechanism for general metabolic rewiring. more...
