Effects of simvaglyzin and atorvaglyzin on the expression of 3-hydroxy-3-methyl-glutaryl-CoA reductase in rat liver

Abstract

Activity and levels of protein and mRNA of 3-hydroxy-3-methyl-glutaryl-CoA reductase were estimated in rat liver after the administration of atorvastatin and simvastatin and their complexes with glycyrrhizic acid (atorvaglyzin and simvaglyzin). The amount of 3-hydroxy-3-methyl-glutaryl-CoA reductase protein in rats decreased by 13 and 25% (p<0.05) 24 h after treatment with atorvaglyzin and simvaglyzin, respectively. Activity of this enzyme decreased by 46% in rats treated with atorvaglyzin. The amount of messenger RNA in these groups significantly increased as compared to control group (untreated animals).
