Simvastatin Modulates Expression of the <i>PON1</i> Gene and Increases Serum Paraoxonase

Abstract

The data indicate that simvastatin can modulate expression in vitro of the antioxidant enzyme paraoxonase and is associated with increased serum paraoxonase concentration and activity. It is consistent with effects of simvastatin treatment, which have the potential to influence beneficially antiatherogenic mechanisms at the HDL level. The study provides evidence for 1 molecular mechanism by which paraoxonase gene expression could be regulated.
