Research published in the February 11th issue of the Cell Press journal Cancer Cell uncovers the genetic origin of such early-onset prostate cancer. The findings could help in the development of new diagnostic, prognostic, therapeutic, and prevention strategies for the disease. http://medicalxpress.com/news/2013-02-genetic-root-early-onset-prostate-cancer.html Cancer Mon, 11 Feb 2013 12:00:05 EST news279803644 A small, naturally occurring nucleic acid sequence, called a microRNA, known to regulate a number of different cancers, appears to alter the activity of the androgen receptor, which plays a critical role in prostate cancer. Directly targeting microRNA-125b to block androgen receptor activity represents a novel approach for treating castrate-resistant prostate cancer. This promising new strategy for improving the effectiveness of anti-androgenic and other hormonal therapies is described in an article in BioResearch Open Access. http://medicalxpress.com/news/2012-07-therapeutic-prostate-cancer.html Cancer Tue, 17 Jul 2012 11:27:26 EST news261743239 A new study lead by the Neuroscience Institute of Alicante reveals how manipulating the endocannabinoid system can modulate high levels of impulsivity. This is the main problem in psychiatric illnesses such a schizophrenia, bipolar disorder and substance abuse. http://medicalxpress.com/news/2012-03-cannabinoid-receptors-impulsive-behavior.html Psychology & Psychiatry Thu, 08 Mar 2012 10:23:50 EST news250424624
