Title Gene expression analysis of Ncor1 muscle-specific knockout and PGC-1alpha muscle-specific transgenic skeletal muscle
Organism Mus musculus
Experiment type Expression profiling by array
Summary 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. The repressive effect of NCoR1 on oxidative phosphorylation gene expression specifically antagonizes PGC-1alpha-mediated coactivation of ERRalpha. We therefore delineated the molecular mechanism by which a transcriptional network controlled by corepressor and coactivator proteins determines the metabolic properties of skeletal muscle, thus representing a potential therapeutic target for metabolic diseases.
Overall design Gene expression of a total of 20 gastrocnemius samples from control (CON, n = 5), NCoR1 muscle-specific knockout (NCoR1 MKO, n = 5), wild type (WT, n = 5) and PGC-1alpha muscle-specific transgenic (PGC-1alpha mTg, n = 5) adult male mice was analyzed using GeneChip® Gene 1.0 ST Array System (Affymetrix). NCoR1 MKO and PGC-1alpha mTg samples were compared to CON and WT samples, respectively.
