Research carried out at the University of Gothenburg may lead to more effective arsenic-containing drugs. The results may also lead to more resistant plants, and crops with a limited absorption and storage of arsenic. http://medicalxpress.com/news/2012-06-arsenic-drugs-cleaner-crops.html Medications Mon, 25 Jun 2012 12:40:02 EST news259844757 Proteins belonging to the large and important family of ABC transporters have been associated with metabolic diseases and can cause resistance to antibiotics. Biochemists from the University of Zurich and the NCCR Structural Biology have succeeded in determining the atomic structure of a new ABC transporter. The insights gained could give rise to new therapies to treat multi-resistant bacteria, cystic fibrosis or gout, for instance. http://medicalxpress.com/news/2012-03-hot-trail-metabolic-diseases-resistance.html Medical research Wed, 28 Mar 2012 10:06:56 EST news252148005 A recent study led by Gergely Lukacs, a professor at McGill University's Faculty of Medicine, Department of Physiology, and published in the January issue of Cell, has shown that restoring normal function to the mutant gene product responsible for cystic fibrosis (CF) requires correcting two distinct structural defects. This finding could point to more effective therapeutic strategies for CF in the future. http://medicalxpress.com/news/2012-03-roadmap-effective-drug-discovery-cystic.html Medical research Mon, 12 Mar 2012 11:14:23 EST news250769655 Researchers at the University of Iowa have worked out the exact function of an enzyme that is critical for normal muscle structure and is involved in several muscular dystrophies. The findings, which were published Jan. 6 in the journal Science, could be used to develop rapid, large-scale testing of potential muscular dystrophy therapies. http://medicalxpress.com/news/2012-01-reveals-enzyme-function-muscular-dystrophy.html Medical research Mon, 09 Jan 2012 13:17:48 EST news245337458 The human genome encodes 243 voltage-gated ion channels. Mutations in calcium channels can cause severe inherited diseases such as migraine, night blindness, autism spectrum disorders and Timothy syndrome, which leads to severe cardiovascular disorders. Katrin Depil and Anna Stary-Weinzinger together with colleagues from the Department of Pharmacology and Toxicology, University of Vienna analyzed changes in molecular organization of calcium channels caused by Timothy syndrome mutations. Recently, they published their current research results in the Journal of Biological Chemistry. http://medicalxpress.com/news/2011-07-timothy-syndrome-mutations-insights-l-calcium.html Medical research Thu, 14 Jul 2011 11:20:03 EST news229860333 A University of Wisconsin-Madison research team has solved a 25-year mystery that may lead to better treatments for people with learning deficits and mental retardation. http://medicalxpress.com/news/2011-06-membrane-protein-mystery.html Neuroscience Wed, 08 Jun 2011 12:00:06 EST news226752886
