(Medical Xpress) -- Researchers at Imperial College London have discovered a molecule that plays an important role in driving prostate cancer growth, and could be a target for new therapies. http://medicalxpress.com/news/2012-07-prostate-cancer-therapy.html Cancer Tue, 03 Jul 2012 05:48:25 EST news260513294 Prostate cancer cells require androgens including testosterone to grow. A recent review in the British Journal of Urology International describes new classes of drugs that target androgens in novel ways, providing alternatives to the traditional methods that frequently carry high side effects. http://medicalxpress.com/news/2012-06-drugs-ways-androgens-prostate-cancer.html Cancer Wed, 20 Jun 2012 12:59:54 EST news259415977 Researchers have identified a potential new pathway in prostate cancer cells by which cancer-driving gene products can be generated, according to a study published in Cancer Discovery, a journal of the American Association for Cancer Research. http://medicalxpress.com/news/2012-06-abnormal-gene-product-prostate-cancer.html Cancer Tue, 19 Jun 2012 10:51:59 EST news259321786 (Medical Xpress) -- Scientists at the University have discovered a protein, only present in prostate cancer cells, that could be used as a marker to detect early signs of the disease.      http://medicalxpress.com/news/2012-05-prostate-cancer-early-protein.html Cancer Thu, 31 May 2012 09:02:23 EST news257673735 Up to half of all prostate cancer cells have a chromosomal rearrangement that results in a new "fusion" gene and formation of its unique protein -- but no one has known how that alteration promotes cancer growth. Now, Weill Cornell Medical College researchers have found that in these cancer cells, the 3-D architecture of DNA, wrapped up in a little ball known as a chromatin, is warped in such a way that a switch has been thrown on thousands of genes, turning them on or off to promote abnormal, unchecked growth. Researchers also found that new chromosomal translocations form, further destabilizing the genome. http://medicalxpress.com/news/2012-05-scientists-unravel-role-fusion-gene.html Cancer Tue, 22 May 2012 16:00:14 EST news256921065 Prostate cancer cells that defy treatment and display heightened tumor-generating capacity can be identified by levels of prostate specific antigen (PSA) expressed in the tumor cells, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in the May 3 edition of Cell Stem Cell. http://medicalxpress.com/news/2012-05-scientists-prostate-cancer-stem-cells.html Cancer Fri, 04 May 2012 13:40:01 EST news255357177 An over-the-counter natural remedy derived from honeybee hives arrests the growth of prostate cancer cells and tumors in mice, according to a new paper from researchers at the University of Chicago Medicine. http://medicalxpress.com/news/2012-05-beehive-potential-prostate-cancer-treatment.html Cancer Fri, 04 May 2012 01:20:02 EST news255313162 A new drug developed by Northwestern Medicine scientists prevented human prostate cancer cells from spreading to other tissues without any toxic effects to normal cells or tissues.

This largest randomized trial of its kind enrolled nearly 2,000 men at low and intermediate risk of prostate cancer progression and followed their health status for more than nine years (October 1994 to April 2001) at 212 centers in the United States and Canada. http://medicalxpress.com/news/2011-07-short-term-hormone-therapy-survival-men.html Cancer Wed, 13 Jul 2011 17:29:13 EST news229796939 A new targeted therapy for prostate cancer halts tumor growth in animals with advanced prostate cancer that is resistant to hormone therapy, a new study finds.
