Common human viruses as carcinogen vectors.
Summary
Viruses can help small amounts of carcinogens cause tumors in mice. Preventing the viral infection stopped tumor growth, showing a link between viruses and cancer development.
Area of Science:
- Oncology
- Virology
- Carcinogenesis
Background:
- Carcinogens are agents known to cause cancer.
- Viruses can play a role in disease development.
- The interaction between viruses and carcinogens requires further investigation.
Purpose of the Study:
- To investigate the synergistic effect of viruses and carcinogens on tumor formation.
- To determine if viral activity is necessary for carcinogen-induced tumors.
Main Methods:
- Male Swiss mice were administered single doses of carcinogens and viruses.
- Tumor development was monitored in mice exposed to carcinogen-virus pairs.
- Mice were pre-immunized against specific viruses to assess the role of viral immunity.
Main Results:
- Malignant tumors developed in mice exposed to five specific carcinogen-virus combinations.
- Tumor formation was prevented in mice immunized against the respective viruses.
- In vitro studies demonstrated poliovirus 2 binding to carcinogens.
Conclusions:
- Viruses can act as co-factors in carcinogen-induced tumor formation.
- Viral presence and activity are critical for the observed synergistic oncogenic effect.
- Targeting viral components may offer a strategy to prevent carcinogen-induced cancers.

Cancers Originate from Somatic Mutations in a Single Cell
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...
Mechanisms of Retrovirus-induced Cancers
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...
Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Rous Sarcoma Virus (RSV) and Cancer
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.
