Expression data from human skeletal muscle in endurance-trained athletes

Endurance-trained athletes have high oxidative capacity, enhanced insulin sensitivity, and high intracellular lipid accumulation in muscle. These characteristics are likely due to altered gene expression levels in muscle. We used microarrays to detect gene expression profile in endurance-trained athlete skeletal muscle. Human skeletal muscle sample selected from Vastus lateralis for RNA extraction and hybridization on Affymetrix microarrays.
