Effect of treatment with placebo or muraglitazar on expression of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α and genes involved in mitochondrial function. The dashed line indicates no change in gene expression. *P < 0.05 versus pre-treatment. †P < 0.05 for the comparison between muraglitazar and placebo therapy-treated groups. Data are shown as means ± se.
