Abstract

In early herpes simplex virus (HSV) infection, the virion host shutoff (vhs) protein mediates the degradation of mRNA and subsequent shutoff of host protein synthesis. It is unclear whether vhs acts alone or in concert with virus-induced cellular factors for this activity. This paper examines whether RNase L, a virally induced endoribonuclease, contributes to HSV-induced mRNA decay. Results showed that RNA degradation was comparable in wild-type and RNase L cells, demonstrating that HSV-mediated RNA degradation is independent of RNase L activity. Furthermore, the data show that HSV-1 does not significantly induce RNase L activity in murine embryo fibroblasts.
