Prostate Cancer May Be
Linked to Virus - RNASEL Gene Defends against Viruses
Comon Flu Viruses
Researchers at the Cleveland Clinic and the University of California San
Francisco have identified a new virus in human prostate tumors. They
are not sure whether this virus is linked to prostate cancer yet.
The virus was found more often in human prostate tumors with two copies
of the RNASEL gene mutation than in tumors with at least one normal copy
of the gene, Forbes reported. Dr. Eric Klein said "This is a virus that
has never been seen in humans before. This is consistent with previous
epidemiologic and genetic research that has suggested that prostate
cancer may result from chronic inflammation, perhaps as a response to
infection." Dr. Klein is head of urologic oncology at the Cleveland
Clinic's Glickman Urologic Institute.
The researchers say that RNASEL is a gene that serves as an important
defense against viruses. Scientists have suspected that this gene
mutation and virus may be responsible for some types of cancer.
The scientists used a new “virus chip” to identify the virus. This chip
was used three years ago to confirm the identity of the SARS virus.
Klein says this finding validates the use of the virus chip to discover
previously unknown viruses. This may help us learn more about viral
causes of disease.
There are other cancers that may be caused or related to viruses. Liver
and cervical cancer could be caused by a virus. Now scientists are
investigating whether diseases may play an important role alongside
genetics in causing breast, stomach and several other forms of cancer.
There are environmental concerns as well. Future treatments and
possible preventative measures may include enzymes that help kill
Prostate cancer is the most common form of cancer among American men,
according to a CBS News report. The finding was reported Friday at an
American Society of Clinical Oncology prostate symposium in San
Francisco. A full report will be published in the journal PloS
