Abstract
The ubiquitin proteasome system plays important role in virus infection A previous study showed that the proteasome inhibitor MG132 could potentially affect hepatitis E virus HEV replication In this study we found that MG132 could inhibit HEV and hepatitis C virus HCV replicationrelated luciferase activity in subgenomic models Furthermore treatment with MG132 in a HEV infectious model resulted in a dramatic reduction in the intracellular level of HEV RNA Surprisingly MG132 concurrently inhibited the expression of a luciferase gene used as a control as well as a wide range of host genes Consistently the total cellular RNA and protein content was concurrently reduced by MG132 treatment suggesting a nonspecific antiviral effect
