According to a study conducted recently, found the possibility of a correlation with the virus triggers prostate cancer disorders.
Ila R. Singh, MD, PhD, a researcher who is also a professor of pathology University of Utah suggests, "We found that there XMRV in 27% of prostate cancer tissues that we check and is associated with more aggressive tumors."
Viruses similar to xenotropic murine leukemia virus (xenotropic murine leukemia virus-related virus or XMRV) has been linked with leukemia and sarcomas (malignant tumors of connective tissue, bone or muscle) in animals, but researchers argue that in recent years, XMRV also been identified in human prostate cancer tissue samples.
If further research confirms that this virus may cause prostate cancer, it means that as discussed by researchers, will open new roads in diagnostic tests, vaccine development, and therapy of prostate cancer.
Causes of Prostate Cancer Hint
In research published in the Proceedings of the National Academy of Sciences, studied 200 prostate cancer tissue samples and 100 samples of healthy prostate tissue. They found that 27% of prostate cancer tissue contains DNA or protein XMRV, while only 6% of healthy prostate cells that contain virus particles. Viruses are also more likely to be found in aggressive prostate cancer.
These studies have been done showing that small men have certain genetic variations that make them more susceptible to infection XMRV, and the virus was found in 10% of cancer tissue samples examined.
XMRV also found in cells of malignant prostate cancer, a discovery that indicates that the virus is allowed to have direct influence in the formation of prostate cancer tumors or there kemunkinan that the virus has a preference for replication in prostate cancer cells.
The researchers mention XMRV infection is not affected by the presence or absence of genetic variation in men that causes them to be more susceptible to infection, so the population "at risk" extends from the men with the genetic predisposition to be all male.
Various viruses have been discovered as another cause of cancer, including cervical cancer (Human Pappiloma) virus and the immune system such as lymphoma (Epstein-Barr Virus). XMRV is a retrovirus that has been known to cause cancer in animals, but has not been shown to cause the same to the human. However, the researchers stated that these findings suggests that further research is needed on the possibility of this virus as the cause of prostate cancer.
