Scientists have shed light on why some people are more susceptible to gout than others. A study has identified 18 new genetic variations that increase levels of uric acid in the blood, which is the main cause of the disease. High levels of uric acid form small crystals in joints and tissues, causing pain and swelling – the main symptoms of the condition once known as the 'disease of kings'. http://medicalxpress.com/news/2012-12-gout-genetic-insight-disease-kings.html Genetics Sun, 23 Dec 2012 13:00:19 EST news275489221 University of Pittsburgh Cancer Institute (UPCI) researchers have identified over 125 genetic components in a chemotherapy-resistant, brain tumor-derived cell line, which could offer new hope for drug treatment to destroy the cancer cells. http://medicalxpress.com/news/2012-12-drugs-defeat-aggressive-brain-tumor.html Cancer Fri, 14 Dec 2012 10:26:52 EST news274702934 Two research studies, co-led by UC Davis neurologist Charles DeCarli and conducted by an international team that included more than 80 scientists at 71 institutions in eight countries, has advanced understanding of the genetic components of Alzheimer's disease and of brain development. Both studies appear in the April 15 edition of the journal Nature Genetics. http://medicalxpress.com/news/2012-04-major-memory-adults-impacted-versions.html Genetics Sun, 15 Apr 2012 13:00:08 EST news253619104 When the intestines are not able to properly process our diet, a variety of disorders can develop, with chronic diarrhea as a common symptom. Chronic diarrhea can also be inherited, most commonly through conditions with genetic components such as irritable bowel syndrome. Researchers in Norway, India, and at the HudsonAlpha Institute for Biotechnology have identified one heritable DNA mutation that leads to chronic diarrhea and bowel inflammation. http://medicalxpress.com/news/2012-03-genetic-mutation-familial-chronic-diarrhea.html Genetics Wed, 21 Mar 2012 17:00:12 EST news251566027
