Rous Sarcoma Virus (RSV) and Cancer

6.7K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Mechanisms of Retrovirus-induced Cancers

7.3K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Cancers Originate from Somatic Mutations in a Single Cell

15.9K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Summary

Simian virus 40 (SV40) antibodies were more common in osteosarcoma (OS) patients. This finding suggests a potential link between SV40 infection and OS development, opening doors for new therapies.

Area of Science:

  • Oncology
  • Virology
  • Immunology

Background:

  • Osteosarcoma (OS) etiology remains largely unknown.
  • Simian virus 40 (SV40) is a suspected oncogenic agent in OS development.

Purpose of the Study:

  • To investigate the association between SV40 and osteosarcoma (OS).
  • To detect immunoglobulin G antibodies against SV40 antigens in OS patient serum.

Main Methods:

  • Indirect enzyme-linked immunosorbent assay (ELISA) was used.
  • Synthetic polypeptides mimicking SV40 capsid protein epitopes were employed as antigens.
  • Serum samples from OS patients, breast cancer patients, nasopharyngeal carcinoma patients, and healthy subjects were analyzed.

Main Results:

  • Prevalence of antibodies reactive to SV40 mimotopes was significantly higher in OS patients (44%) compared to healthy subjects (17%).
  • Significant differences in antibody prevalence were observed between OS patients and those with breast cancer (44% vs. 15%) and undifferentiated nasopharyngeal carcinoma (44% vs. 25%).

Conclusions:

  • The study indicates a significant association between osteosarcoma and Simian virus 40.
  • Findings suggest potential for novel therapeutic strategies targeting SV40 in osteosarcoma treatment.
