Researchers at the Harvard Medical School investigated the effect of androgen deprivation in a preclinical mouse model of stable high grade prostatic intraepithelial neoplasia induced by the loss of the PTEN tumor suppressor. They found that androgen deprivation treatment of these mice accelerated the progression to invasive disease. Shidong Jia, M.D., Ph.D. And associates found [...]
The University of South Florida along with Moffitt Cancer Center has published a study in the October issue of Brain, Behavior, and Immunity which found that men with advanced prostate cancer who are on androgen deprivation therapy (ADT) are more likely to suffer from general fatigue if they also have single nucleotide polymorphisms in three [...]
Genomic Health, Inc. has announced they have had positive results from a large clinical validation study of a biopsy-based prostate cancer test designed to predict adverse pathology in men with early prostate cancer. The study, performed in collaboration with prostate cancer researchers at the University of California, San Francisco (UCSF), met its primary endpoint by [...]
According to a study published online May 9 in The American Journal of Pathology copy number variations (CNV) in both malignant and benign prostate tissue is predictive of prostate cancer relapse. The research performed at the University of Pittsburgh School of Medicine by Yan P. Yu, M.D. and colleagues evaluated whether CNV of the genomes [...]
Men who inherit a mutation in the HOXB13 gene have a 10 to 20 times increased risk of developing prostate cancer, according to the study in the January 12, 2012 issue of the New England Journal of Medicine. Finally, the first major gene mutation associated with an increased risk for prostate cancer has been identified. [...]
We know that both a positive family history and racial background are among the strongest epidemiological risk factors for prostate cancer. It is also recognized that the role of candidate genetic markers to prostate cancer is more difficult to identify than the identification of other cancer susceptibility genes. Despite the localization of several susceptibility loci, [...]
In today's issue of Cancer Discovery a group of international researchers report that an investigational drug had a dramatic response in animal models of neuroendocrine prostate cancer, a lethal form of the disease. The researchers pointed out that fewer than 2% of prostate tumors in men are initially diagnosed as neuroendocrine, but many of the [...]
A study at The Cleveland Clinic has discovered that a gene – known as an androgen receptor (AR) is present in both breast and prostate cancers, but the gene has opposite effects on these diseases. The AR gene promotes prostate cancer when the gene is “turned on,” but in breast cancer the AR gene promotes [...]
According to research published today in the British Journal of Cancer, routine testing for a faulty BRCA2 gene (Kote-Jarai Z et al, BRCA2 is a gene contributing to young onset prostate cancer: implications for genetic testing in prostate cancer patients British Journal of Cancer (2011) doi:10.1038/bjc.2011.383) in men under 65 years with prostate cancer could [...]
Finally, advanced prostate cancer makes it into the genomeic world of cancer. Researchers at the Fred Hutchinson Cancer Research Center and the University of Washington in Seattle published in this week's online edition of the Proceedings of the National Academy of Sciences an announcement that they have mapped the genomes of three different types of [...]
