Genetic variations in the micro-RNA (miRNA) processing pathway genes and miRNA binding sites predict a woman's risk for developing ovarian cancer and her prospects for survival, researchers from The University of Texas M. D. Anderson Cancer Center reported at the 100th annual meeting of the American Association for Cancer Research. http://www.physorg.com/news159374503.html Medicine & Health Sun, 19 Apr 2009 15:44:05 EST news159374503 Researchers from Boston University School of Medicine (BUSM) have demonstrated that a recently discovered class of molecule called microRNA (miRNAs), regulate the gene expression changes in airway cells that occur with smoking and lung cancer. These findings, which appear in the on-line early edition of journal Proceedings of the National Academy of Sciences, may lead to a new, relatively non-invasive biomarker for smoking-related lung diseases. http://www.physorg.com/news151076573.html Biology Tue, 13 Jan 2009 13:42:53 EST news151076573
