This allows Salmonella to selectively change its levels of certain proteins to respond to inhospitable conditions. http://news.biocompare.com/newsstory.asp?id=335979 Biocompare.com Fri, 30 Jul 2010 14:13:00 GMT The apparently random self-assembly of molecular threads into the proteins that make the body work is far less frantic than previously thought, Michigan State University scientists say. That discovery could be a key to help unlock the nature of some diseases. http://news.biocompare.com/newsstory.asp?id=335977 Biocompare.com Fri, 30 Jul 2010 14:08:00 GMT Resveratrol, a popular plant extract shown to prolong life in yeast and lower animals due to its anti-inflammatory and antioxidant properties, appears also to suppress inflammation in humans, based on results from the first prospective human trial of the extract conducted by University at Buffalo endocrinologists. http://news.biocompare.com/newsstory.asp?id=335972 Biocompare.com Fri, 30 Jul 2010 13:48:00 GMT LA JOLLA, Calif., July 29, 2010 - Although their genetic underpinnings differ, Alzheimer's disease, Parkinson's disease and Huntington's disease are all characterized by the untimely death of brain cells. What triggers cell death in the brain? According to a new study published by researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) in the July 30 issue of Molecular Cell, the answer in some cases is the untimely transfer of a gaseous molecule (known as nitric oxide, or NO) from one protein to another. http://news.biocompare.com/newsstory.asp?id=335971 Biocompare.com Fri, 30 Jul 2010 13:47:00 GMT Louisville, Ky. -- People with a family history of male breast cancer perceive themselves to be at higher risk of developing the disease than do patients with a family history of female breast cancer; however those with male breast cancer in their families are less likely to know about or seek genetic testing than those with a family history of female breast cancer, according to a study led by researchers at the University of Louisville's James Graham Brown Cancer Center. http://news.biocompare.com/newsstory.asp?id=335969 Biocompare.com Fri, 30 Jul 2010 13:43:00 GMT PITTSBURGH-Researchers at Carnegie Mellon University have developed a new fluorescent biosensor that could aid in the development of an important class of drugs that target a crucial class of proteins called G protein-coupled receptors (GPCRs). http://news.biocompare.com/newsstory.asp?id=335968 Biocompare.com Fri, 30 Jul 2010 13:42:00 GMT HOUSTON - Researchers have discovered an enzyme crucial to a type of DNA repair that also causes resistance to a class of cancer drugs most commonly used against ovarian cancer. http://news.biocompare.com/newsstory.asp?id=335964 Biocompare.com Fri, 30 Jul 2010 13:25:00 GMT A type of prostate cell that has been largely ignored by cancer researchers can, in fact, trigger malignant prostate cancer, according to new studies by Howard Hughes Medical Institute (HHMI) scientists and their colleagues. http://news.biocompare.com/newsstory.asp?id=335963 Biocompare.com Fri, 30 Jul 2010 13:21:00 GMT BOSTON -- The recent discovery of more than a thousand genes known as large intergenic non-coding RNAs (or "lincRNAs") opened up a new approach to understanding the function and organization of the genome. That surprising breakthrough is now made even more compelling with the finding that dozens of these lincRNAs are induced by p53 (the most commonly mutated gene in cancer), suggesting that this class of genes plays a critical role in cell development and regulation. Furthermore, the researchers identify one lincRNA in particular (lincRNA-p21), and demonstrate its critical role in suppressing the reading of many genes across the genome following p53 activation. Led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and the Broad Institute, the results are published in the August 6 issue of the journal Cell, which appears on-line today. http://news.biocompare.com/newsstory.asp?id=335957 Biocompare.com Fri, 30 Jul 2010 13:03:00 GMT
