Abstract
Human cytomegalovirus infection of human fibroblast cells (WI-38) induced cellular RNA synthesis. The RNA synthesis in infected cultures preceded the synthesis of viral DNA and progeny virus by approximately 24 h. RNA species synthesized in infected cells included ribosomal 28S and 18S; and 4S transfer RNA; all were markedly increased in comparison to uninfected cells. This induction of host cell RNA synthesis was dependent upon a protein(s) that was synthesized during the early stages of infection.
