Quercetin and Quercetin-Rich Red Onion Extract Alter Pgc-1α Promoter Methylation and Splice Variant Expression

Figure 1

Pgc-1α mRNA was measured by qRT-PCR in skeletal muscle samples of mice fed a low fat (LF), high fat (HF), high fat plus quercetin (HF + Q), or high fat plus red onion extract (HF + RO) diet for 9 wks. Values are shown as means ± SEM in arbitrary units (AU).
