The study, published this month in the journal Neuron, is the first evidence that exosomes can transfer membrane proteins that play an important role in cell-to-cell signaling in the nervous system. http://medicalxpress.com/news/2013-03-intercellular-potential-rnai-gene-based-therapeutics.html Neuroscience Wed, 27 Mar 2013 10:10:01 EST news283596137 The widely held belief that the UK supply of innovative new medicines has conspicuously dwindled in recent decades, is not borne out by the evidence, reveals research published in the online journal BMJ Open. http://medicalxpress.com/news/2013-02-myth-uk-pharma-drugs.html Medications Wed, 20 Feb 2013 18:30:02 EST news280604669 (Medical Xpress)—Doctors may one day treat some forms of blindness by altering the genetic program of the light-sensing cells of the eye, according to scientists at Washington University School of Medicine in St. Louis. http://medicalxpress.com/news/2013-01-eye-cells-day-vision.html Ophthalmology Fri, 25 Jan 2013 06:46:28 EST news278318773 (Medical Xpress)—A new Australian study led by Professor Susan Clark from Sydney's Garvan Institute of Medical Research shows that large regions of the genome – amounting to roughly 2% – are epigenetically activated in prostate cancer. http://medicalxpress.com/news/2012-12-cancer-overturns-current-gene.html Cancer Tue, 18 Dec 2012 16:06:03 EST news275069088 Investigators are looking into two main paths toward a cure for AIDS, based on the stunning stories of a small group of people around the world who have been able to overcome the disease. http://medicalxpress.com/news/2012-07-aids-main-pathways-experts.html HIV & AIDS Tue, 24 Jul 2012 11:10:51 EST news262347044
