Summary
A novel SV40-like virus was discovered in most Merkel cell carcinomas using a new non-human transcript detection method. Further research is needed to confirm if this virus plays a role in cancer development.
Area of Science:
- Virology
- Oncology
- Genomics
Background:
- Merkel cell carcinoma (MCC) is a rare but aggressive skin cancer.
- The etiology of MCC is not fully understood, but viral infections are implicated in some cases.
Purpose of the Study:
- To investigate the presence of novel viral agents in Merkel cell carcinomas.
- To explore the potential role of a newly identified SV40-like virus in MCC carcinogenesis.
Main Methods:
- Development and application of a novel technique for identifying non-human transcripts.
- Analysis of tumor samples from Merkel cell carcinoma patients.
Main Results:
- Identification of a novel SV40-like virus in the majority of analyzed MCC samples.
- The detected virus shares similarities with the Simian virus 40 (SV40).
Conclusions:
- A novel SV40-like virus is frequently associated with Merkel cell carcinomas.
- Further studies are required to establish a causal link between this virus and cancer development.

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.

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...

Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
