SV40 is an abbreviation for simian vacuolating virus 40 or simian virus 40, a polyomavirus that is found in both monkeys and humans.Like other polyomaviruses, SV40 is a DNA virus that is found to cause tumors in humans and animals, but most often persists as a latent infection.
Vaccine contamination with Simian vacuolating virus 40, known as SV40 occurred in the United States and other countries between 1955 and 1961. SV40 is a monkey virus that has the potential to cause cancer in animals and humans, although this is considered very unlikely and there have been no known human cases. [1]
SV40 large T antigen (Simian Vacuolating Virus 40 TAg) is a hexamer protein that is a dominant-acting oncoprotein derived from the polyomavirus SV40.TAg is capable of inducing malignant transformation of a variety of cell types.
Merkel cell polyomavirus (MCPyV) is a virus causally associated with a rare and aggressive human skin cancer called Merkel cell carcinoma. MCPyV genetic material is often found integrated into the tumor cell genome, usually with mutations in the tumor antigen genes that abrogate the helicase activity of LTag, which is required for normal viral ...
Simian virus 40. Butel has studied polyomavirus SV40 infection in humans and animals for most of her career. She has published studies on the mechanism of SV40 entry into human cells, the role of SV40 in cancer and SV40 genetics. In addition, Butel published an article in 2014 on the use of microRNA and SV40 in golden hamsters. [2]
COS-7 cells, 40X magnification. COS are fibroblast-like cell lines derived from monkey kidney tissue. COS cells are obtained by immortalizing CV-1 cells [1] with a version of the SV40 virus that can produce large T antigen but has a defect in genomic replication. [2]
The Oral polio vaccine AIDS hypothesis (OPV AIDS) is a now-discredited hypothesis which argued the AIDS pandemic originated from live polio vaccines prepared in chimpanzee tissue cultures, accidentally contaminated with simian immunodeficiency virus and then administered to up to one million Africans between 1957 and 1960 in experimental mass vaccination campaigns.
The SV40 Cancer Foundation was founded by Raphaele and Michael Horwin. The Horwin's son Alexander Horwin was born on June 7, 1996, and was given oral polio vaccine in November 1997. On August 10, 1998, Alexander was diagnosed with medulloblastoma , a malignant (cancerous) pediatric brain tumor , leading to his death on January 31, 1999.
