Fig. 6From: In vivo effects of dietary quercetin and quercetin-rich red onion extract on skeletal muscle mitochondria, metabolism, and insulin sensitivitymRNA levels of genes encoding polypeptides for subunits of the mitochondrial complex I (a) complex III (b) complex IV (c) and complex V (d) were determined by qRT-PCR using the standard curve method in skeletal muscle samples. Values are reported as mean ± SEM in arbitrary units (AU). Significant differences between groups were determined by one-way ANOVA and post hoc Tukey. Differing superscripts indicate significant differences between groups at P < 0.05. ND NADH dehydrogenase, CytB cytochrome B, COX cyclooxygenase, and ATP adenosine triphosphateBack to article page
