Adipocyte tissue is central to regulate energy balance. PGC-1 alpha controls several aspects of mitochondrial biogenesis. However, roles of PGC-1 alpha in brown fat differentiation of MSCs remain uncertain. To investigate roles of PGC-1 alpha in brown fat differentiation immortalized human MSCs were used for all experiments. The changes in genetic profiling between MSCs and PGC-1 alpha-expressing MSCs were analyzed by microarray analysis. The genetic profiling of PGC-1 alpha-expressing MSCs shows the significant increase of genes related to mitochondrial functions and lipid metabolism compared to that of MSCs. When expressed in MSCs, PGC-1 alpha activates a robust mitochondrial biogenesis and respiration. The expression of thermogenic markers, such as cytochrome C and complex II, was significantly increased in MSCs with treatment of adenovirus expressing PGC-1 alpha. Our microarray results also indicate that genetic pattern of PGC-1 alpha-expressing MSCs is very closed to that of adipose tissues.  Bone marrow-derived MSCs were infected with Ad-GFP, or Ad-PGC-1&#945; at a multiplicity of infection (m.o.i.) of 500 overnight.</item><item key="source">http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-19643</item><item key="sample_source">http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-19643/samples/</item></data></biogps>
