Expression of the brown fat thermogenic gene program requires PGC-1alpha

(Submitter supplied) To investigate the specific role of PGC-1 coactivators in brown fat cells, we generated immortal preadipocyte lines from the brown adipose tissue of mice lacking PGC-1alpha. We could then efficiently knockdown PGC-1beta expression by shRNA expression. Loss of PGC-1alpha did not alter brown fat differentiation but severly reduced the induction of thermogenic genes. In order to assess the specific requirement for PGC-1α in the global transcriptional response to cAMP, we used Affymetrix arrays to compare the sets of genes induced in response to a 4 hr dbcAMP treatment in differentiated wt and KO cells. more...

Complementary action of the PGC-1 coactivators in mitochondrial biogenesis and brown fat differentiation

(Submitter supplied) Mitochondria play an essential role in the ability of brown fat to generate heat, and the PGC-1 coactivators control several aspects of mitochondrial biogenesis. To investigate their specific roles in brown fat cells, we generated immortal preadipocyte lines from the brown adipose tissue of mice lacking PGC-1α. We could then efficiently knockdown PGC-1β expression by shRNA expression. Loss of PGC-1α did not alter brown fat differentiation but severely reduced the induction of thermogenic genes. more...

Remodeling of Brown and White Adipose Tissue by NT-PGC-1α-Mediated Gene Regulation

(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...

Expression data from white adipose tissue of Perilipin A transgenic mice

(Submitter supplied) Perilipin A (PeriA) exclusively locates on adipocyte lipid droplets and is essential for lipid storage and lipolysis. Adipocyte specific overexpression of PeriA caused resistance to diet-induced obesity and resulted in improved insulin sensitivity. In order to better understand the biological basis for this observed phenotype we performed DNA microarray analysis on white adipose tissue (WAT) from PeriA transgenic (Tg) and control wildtype (WT) mice.

Pyruvate induces mitochondrial biogenesis by a PGC-1alpha independent mechanism

(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...

Histone Deacetylase 3 Prepares Brown Adipose Tissue For Acute Thermogenic Challenge [RNA-Seq]

(Submitter supplied) Brown adipose tissue (BAT) is a thermogenic organ that requires Uncoupling Protein 1 (UCP1) to dissipate chemical energy as heat, to defend core body temperature against hypothermia, and counteract obesity and metabolic diseases1. However, the transcriptional mechanism ensuring BAT thermogenic capacity for survival prior to environmental cold is unknown. Here we show histone deacetylase 3 (HDAC3) is a required transcriptional regulator of BAT enhancers to ensure thermogenic aptitude and survival. more...

Gene Expression Profiling of PGC-1a KO mouse striata

(Submitter supplied) Huntington’s Disease (HD) is an inherited neurodegenerative disease caused by a glutamine repeat expansion in huntingtin protein. Transcriptional deregulation and altered energy metabolism have been implicated in HD pathogenesis. We report here that mutant huntingtin causes disruption of mitochondrial function by inhibiting expression of PGC-1a, a transcriptional coactivator that regulates several metabolic processes including mitochondrial biogenesis and respiration. more...

PGC-1α and NT-PGC-1α are highly induced by cold in BAT and subsequently bind to and coactivate many different transcription factors to regulate expression of genes involved in mitochondrial biogenesis, fatty acid oxidation, respiration and thermogenesis. more...

Microarray of cardiac biventricle from PGC-1a-/-bf/f/MerCre mice

(Submitter supplied) The following abstract from the submitted manuscript describes the major findings of this work. The metabolic development of high energy-utilizing organs such as the heart involves mitochondrial proliferation at birth followed by a maturation process during the postnatal period. Conditional gene targeting was used in mice to explore the role of the PPARgamma coactivator 1 (PGC-1) coactivators during postnatal development and in adult heart. more...
