title: Identification of a gene function of herpes simplex virus type 1 essential for amplification of simian virus 40 DNA sequences in transformed hamster cells.
abstract: Infection with herpes simplex viruses (HSV) lead to a significant increase of the simian virus 40 (SV40) DNA content in the SV40-transformed hamster cell lines CO631 and Elona. Analysis of this gene-amplifying activity revealed (i) that it cosedimented with infectious herpesvirions in sucrose density gradients, (ii) that it was abolished by anti-HSV antibodies or (iii) by antiviral drugs acting on the HSV-induced DNA polymerase; and analysis of temperature-sensitive mutants showed that this DNA polymerase was an essential component of HSV-induced, gene-amplifying activity in SV40-transformed hamster cells.
