title: Trans activation of plasmid-borne promoters by adenovirus and several herpes group viruses.
abstract: This paper describes experiments to test the ability of a number of viruses of the Herpes group, and also Adenovirus-2 and SV40, to activate transcription from the Herpes simplex virus-1 glycoprotein D and the rabbit beta-globin promoters. Plasmids containing these genes were transfected into HeLa cells which were then infected with various viruses. Transcriptional activation in trans of the plasmid-borne promoters was monitored by quantitative S1 nuclease analysis of total cytoplasmic RNA isolated after infection. The results showed that Herpes simplex viruses 1 and 2, Pseudorabies virus, Variella Zoster virus, Human Cytomegalovirus, Equine herpes virus-1 and Adenovirus-2 activate transcription from both promoters tested. In contrast, SV40 did not activate transcription in trans in this assay. The possible mechanisms of this activation are discussed.
