Quercetin Increases Hepatic Homocysteine Remethylation and Transsulfuration in Rats Fed a Methionine-Enriched Diet

Figure 1

Hepatic MS mRNA expression and activity. MS, methionine synthase; 0.5% Q, 0.5% quercetin supplemented group; 1.0% Met, 1.0% Met supplemented group; 1.0% Met/0.5% Q, 1.0% Met plus 0.5% quercetin supplemented group. (a) Effect of quercetin on hepatic MS mRNA expression in rats fed a Met-enriched diet for 6 weeks. The mRNA expression of MS was normalized to β-actin. (b) Effect of quercetin on hepatic MS activity in rats fed a Met-enriched diet for 6 weeks. Results are expressed as mean and standard deviation (). different from the control (). different from the 0.5% Q group (). different from the 1.0% Met group ().
