Researchers identified a new chromosomal abnormality in acute lymphoblastic leukemia (ALL) that appears to work in concert with another mutation to give rise to cancer. This latest anomaly is particularly common in children with Down syndrome. http://www.physorg.com/news175092371.html Medicine & Health Sun, 18 Oct 2009 13:46:46 EST news175092371 An international team of scientists has identified two more genetic risk factors for Alzheimer's disease. The findings are reported in the online edition of the journal Nature Genetics. http://www.physorg.com/news171461698.html Medicine & Health Sun, 06 Sep 2009 13:17:05 EST news171461698 Most cancers are rare in people with Down syndrome, whose overall cancer mortality is below 10 percent of that in the general population. Since they have an extra copy of chromosome 21, it's been proposed that people with Down syndrome may be getting an extra dose of one or more cancer-protective genes. The late cancer researcher Judah Folkman, MD, founder of the Vascular Biology Program at Children's Hospital Boston, popularized the notion that they might be benefiting from a gene that blocks angiogenesis, the development of blood vessels essential for cancer's growth, since their incidence of other angiogenesis-related diseases like macular degeneration is also lower. A study from Children's confirms this idea in mice and human cells and identifies specific new therapeutic targets for treating cancer. http://www.physorg.com/news162043998.html Medicine & Health Wed, 20 May 2009 13:14:02 EST news162043998 A newly identified molecular pathway that directs stem cells to produce glial cells yields insights into the neurobiology of Down's syndrome and a number of central nervous system disorders characterized by too many glial cells, according to a recent study by researchers at the Salk Institute for Biological Studies. http://www.physorg.com/news156174646.html Biology Fri, 13 Mar 2009 14:51:52 EST news156174646 Researchers at The University of Arizona are developing a set of standardized tests that could improve the lives of people with Down syndrome. http://www.physorg.com/news150991781.html Medicine & Health Mon, 12 Jan 2009 14:09:41 EST news150991781
