| New study redefines how plaques grow in heart disease Posted: 11 Aug 2013 12:08 PM PDT The growth of deadly plaque inside the walls of arteries may not happen as scientists believed, researchers have found. New research also suggests a new potential target in the treatment of atherosclerosis, a leading cause of cardiovascular disease and death globally.  |
| New patterns found in the genetic relationship of five major psychiatric disorders Posted: 11 Aug 2013 12:08 PM PDT An international consortium has shown for the first time evidence of substantial overlap of genetic risk factors shared between bipolar disorder, major depressive disorder and schizophrenia and less overlap between those conditions and autism and attention deficit-hyperactivity disorder, according to a new study.  |
| New data reveal extent of genetic overlap between major mental disorders Posted: 11 Aug 2013 12:08 PM PDT The largest genome-wide study of its kind has determined how much five major mental illnesses are traceable to the same common inherited genetic variations. Researchers found that the overlap was highest between schizophrenia and bipolar disorder; moderate for bipolar disorder and depression and for ADHD and depression; and low between schizophrenia and autism. Overall, common genetic variation accounted for 17-28 percent of risk for the illnesses.  |
| Neuroscientists identify protein linked to Alzheimer's-like afflictions Posted: 11 Aug 2013 12:05 PM PDT A team of neuroscientists has identified a modification to a protein in laboratory mice linked to conditions associated with Alzheimer's Disease. Their findings also point to a potential therapeutic intervention for alleviating memory-related disorders.  |
| Newly identified genetic factors drive severe childhood epilepsies Posted: 11 Aug 2013 12:05 PM PDT Researchers have identified two new genes and implicated 25 distinct mutations in serious forms of epilepsy, suggesting a new direction for developing tailored treatments of the neurological disorders.  |
| Posted: 11 Aug 2013 12:05 PM PDT A decade ago, gene expression seemed so straightforward: genes were either switched on or off. Not both. Then in 2006, a blockbuster finding reported that developmentally regulated genes in mouse embryonic stem cells can have marks associated with both active and repressed genes, and that such genes, which were referred to as "bivalently marked genes", can be committed to one way or another during development and differentiation.  |
