RESUMO
RNAs which are synthesized and accumulate in the cytoplasm of uninfected and herpes simplex virus type 1 (HSV-1)-infected xeroderma pigmentosum (XP) cells in the presence of cycloheximide (early RNAs) or absence of drugs (late RNAs) were analyzed by electrophoresis through denaturing polyacrylamide gradient slab gels. HSV RNAs were selected by hybridization ot HSV DNA covalently bound to cellulose. No HSV-specific low-molecular-weight (4S to 10S) RNAs were detected. However, several changes were observed in the electrophoretic pattern of the host low-molecular-weight RNAs during HSV infection. Five HSV RNAs ranging in size from 16S to 28S accumulated in the cytoplasm of infected XP cells in the presence of cycloheximide. These are of the size range predicted to encode the major early viral polypeptides. The cytoplasmic and polyadenylated early RNAs from HSV-infected XP cells were translated in vitro to produce proteins whose electrophoretic pattern resembled that of the early viral proteins synthesized in vivo.
