Analyses of genes regulating mitochondrial biogenesis. a Western analysis was performed for PGC-1α expression and normalized to HSP90 expression. (bottom) Quantitation of PGC-1α expression was performed. b CS activity was analyzed in GC muscle. Data are presented as the means ± SD. Arid5b+/+ mice (n = 7) and Arid5b−/− mice (n = 5)
