Core Tip	S-adenosyl-L-methionine (SAM) downregulates hepatitis C virus (HCV) expression by unknown mechanisms. We evaluated the effects of SAM on viral expression using an HCV subgenomic replicon cell culture system. We observed that SAM induces a synergic antiviral effect with standard interferon (IFN) treatment independently of IFN signaling pathways; it does not modify viral RNA stability, but it needs cellular translation machinery in order to decrease HCV expression. In addition, results demonstrated that a likely mechanism(s) by which SAM decreases HCV expression could involve modulating antioxidant enzyme systems, restoring biosynthesis of glutathione and switching methionine adenosyltransferase 1 (MAT1)/MAT2 turnover in HCV expressing cells.
