Analysis of gene expression using simian virus 40 vectors.
Extensive studies on the DNA tumor virus Simian Virus 40 (SV40) have provided a wealth of information regarding the genome organization, regulation of viral gene expression, and the mechanism of DNA replication. SV40 can grow lytically in permissive monkey cells or the viral DNA can integrate into the host genome of nonpermissive rodent cells causing morphological transformation. The viral DNA exists as a minichromosome within the nuclei of lytically infected cells and, as a consequence of DNA replication, there is a significant amplification of the viral genome during infection. These properties suggested that SV40 could be developed as a transducing vector to introduce exogenous DNA into mammalian cells and to express this foreign DNA during the SV40 infectious cycle. In this article the properties of SV40 virus vectors and SV40 hybrid plasmid vectors are described and contrasted.
