A new resource to define the roles of microRNAs is announced today in Nature Biotechnology. The resource, called mirKO, gives researchers access to tools to investigate the biological role and significance for human health of these enigmatic genes. http://medicalxpress.com/news/2011-08-resource-role-micrornas.html Medical research Sun, 07 Aug 2011 13:38:27 EST news231943084 Researchers from Harvard Medical School and MIT have developed a new approach for identifying the "self" proteins targeted in autoimmune diseases such as multiple sclerosis, diabetes and rheumatoid arthritis. http://medicalxpress.com/news/2011-06-approach-autoimmune-diseases.html Medical research Thu, 02 Jun 2011 11:20:04 EST news226230343 Researchers at The University of Western Ontario have discovered a strategy for stimulating the formation of highly functional new blood vessels in tissues that are starved of oxygen. Dr. Geoffrey Pickering and Matthew Frontini at the Schulich School of Medicine & Dentistry developed a strategy in which a biological factor, called fibroblast growth factor 9 (FGF9), is delivered at the same time that the body is making its own effort at forming new blood vessels in vulnerable or damaged tissue. The result is that an otherwise unsuccessful attempt at regenerating a blood supply becomes a successful one. Their findings are published online in Nature Biotechnology. http://medicalxpress.com/news/2011-04-successful-strategy-regenerate-blood-vessels.html Medical research Sun, 17 Apr 2011 13:04:04 EST news222264228
