Abstract:
:Bovine herpesvirus 1 (BHV-1) gene expression was examined by RNA blot hybridization using clones representing immediate-early, early, and late genes. An immediate-early protein gene probe hybridized with two transcripts, 3.4 and 5.8 kb, expressed by infected cells in the presence of cycloheximide (CH). During infection of cells without metabolic inhibitors these transcripts were detected as early as 2 hr postinfection (p.i.) and accumulated to 8 hr p.i. The early gene probe, thymidine kinase, hybridized with a 4.3-kb RNA that was detected in the presence of phosphonoacetic acid (PAA), but not in the presence of CH. The late gene probe, glycoprotein III, (gIII) hybridized with a 1.6-kb transcript that was not expressed by infected cells treated with CH and only in very reduced amounts by infected cells treated with PAA. The gIII RNA was not detected until 4 hr p.i. in total cell RNA. Transcripts for the bovine actin and beta-galactosyltransferase genes did not decrease in BHV-1-infected cells until 6 hr p.i., coincident with the increase of BHV-1 DNA and RNA synthesis. Consequently, shutoff of host cell transcription by BHV-1 may be different than what has been described for herpes simplex virus.
