Effect of 5-methylcytidine on virus production in avian sarcoma virus-infected chicken embryo cells.

5-Methylcytidine (5mC) is a minor constituent of RNA in procaryotes as well as eucaryotes. The function of this modified nucleoside is not known. We studied the effect of this compound on virus production in avian sarcoma virus-infected chicken embryo fibroblasts. We found, surprisingly, that virus release into the medium was severely reduced in cultures treated with 5mC. In contrast to the effect of 5mC on virus release, intracellular levels of virus-specific RNA transcripts as well as the proteins were slightly elevated. Analysis of intracellular RNA transcripts on velocity gradients and virus-specific proteins in polyacrylamide gels did not reveal any qualitative differences in 5mC-treated cells compared to cytidine-treated cells. From these results we conclude that the effect of 5mC is probably at the level of virus maturation or packaging.[1]
