(Submitter supplied) PGC1beta is a transcriptional coactivator that potently stimulates mitochondrial biogenesis and respiration of cells. Here, we have generated mice lacking exons 3 to 4 of the Pgc1beta gene (PGC1beta E3,4-/E3,4- mice). These mice express a mutant protein that has reduced coactivation activity on a subset of transcription factors, including ERRalpha, a major target of PGC1beta in the induction of mitochondrial gene expression. more...

(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...

(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...

Analysis of PGC-1alpha null brown adipocytes treated with cAMP for 4 hours. PGC-1alpha is required for the thermogenic function of brown fat cells, and cAMP plays a role in thermogenesis. Results provide insight into the role of PGC-1alpha in the global transcriptional response to cAMP.

Analysis of brown fat cells lacking PGC-1alpha or both PGC-1alpha and PGC-1beta. PGC-1alpha is required for the thermogenic function of brown fat cells, and PGC-1beta is the closest homolog of PGC-1alpha.

(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...

(Submitter supplied) Regulation of gene expression is an important aspect of insulin’s physiological action, however, most studies rely on in vitro systems or pharmacological doses of insulin. Here, we demonstrate that under euglycemic-clamp conditions, physiological levels of insulin regulate over 1500 transcripts in muscle and 1000 transcripts in liver. These include expected pathways related to glucose and lipid utilization, mitochondrial function and autophagy in muscle, and glucose production and steroidogenesis in liver, as well as unexpected pathways, such as mRNA splicing, chromatin remodeling, and regulation of hepatocyte nuclear factors. more...

(Submitter supplied) Insulin resistance, a harbinger of the metabolic syndrome, is a state of compromised hormonal response for which transcriptional dysregulation is a major contributor. Genetic or pharmacological inhibition of the nuclear receptor ERRα preserves insulin sensitivity during diet-induced obesity. However, how ERRα integrates insulin signaling at the molecular level with whole body metabolism remains unknown. more...
