Evaluation by real-time quantitative RT-PCR of the LV mRNA levels of 11 genes related to cardiac metabolism in 9-month rats and impact of endurance training. Results are reported in arbitrary units as mean ± SEM (n = 15/gr). Levels in sham animals were fixed to 1. FAT/CD36: fatty acid transporter/CD antigen 36, CPT1b: carnitine palmitoyltransferase 1b and CPT2: carnitine palmitoyltransferase 2, Glut1: glucose transporter 1, Glut4: glucose transporter 4, PDH1a: pyruvate dehydrogenase 1 alpha and PDK4: pyruvate dehydrogenase kinase 4, PPARα: peroxisome proliferator activator receptor alpha, PGC-1α: Peroxisome proliferator-activated receptor gamma coactivator-1-alpha, UCP3: uncoupling protein 3 and ANT: adenine nucleotide translocase. P values are indicated above each bar compared to sham controls. ¶p < 0.05 between AR and AR-tr groups.
