9 Ιουλ 2007 · Simian virus 40 (SV40) is a monkey virus that was administered to human populations by contaminated vaccines which were produced in SV40 naturally infected monkey cells.
1 Μαρ 2022 · Abstract. The extensive poliovirus vaccination programs of the late 1950s and early 1960s lead to the accidental infection of millions of individuals with an unknown virus (SV40) possessing cancer-causing potential. This mistake sparked a massive research enterprise to understand this newly discovered virus.
With standard protocols for DNA infection, only a small fraction (about 4%) of monkey cells exposed to purified DNA of simian virus 40 (SV40) exhibits signs of infection. We have devised a protocol by which we can extend the time of exposure of BSC-1 cells to DNA in the presence of low concentrations of DEAE-dextran.
The polyomavirus simian virus 40 (SV40) is a known oncogenic DNA virus which induces primary brain and bone cancers, malignant mesothelioma, and lymphomas in laboratory animals. Persuasive evidence now indicates that SV40 is causing infections in humans today and represents an emerging pathogen.
SV40 was isolated from normal monkey kidney cells, stocks of the Sabin poliovirus vaccine, and an adenovirus vaccine. The last two reagents were prepared in primary kidney cell cultures derived from rhesus monkeys.
As with other DNA tumor viruses, the response of cultured cells to SV40 infection depends upon the species being infected. Monkey cells s- port virus production, which leads to their death, whereas rodent cells p- duce only the early proteins and acquire a transformed phenotype.
20 Ιαν 1999 · SV40 is a potent DNA tumor virus that induces tumors in rodents and transforms many types of cells in culture, including those of human origin. This virus has been a favored laboratory model for mechanistic studies of molecular processes in eukaryotic cells and of cellular transformation.
