Changes in silent mating type information regulation 2 homolog 1 (SIRT1; A), peroxisome proliferator-activated receptor (PPAR)γ coactivator-1α (PGC-1α; B), PPARδ (C), mitochondrial transcription factor A (mtTFA; D), and cytochrome c (E) mRNA expression in the RG muscle. Values are means ± SE (n = 6–8). #Significant difference between 20- and 40-wk values within respective animal group (P < 0.01). †Significantly different from OLETF-SED at respective age (P < 0.05). *Significantly different from LETO-SED at respective age (P < 0.05).
