Ancient DNA helps unearth potential hemophilia therapy A cut could be life-threatening for those who have hemophilia, whose bodies don’t make enough of a proteins that prevents prolonged bleeding. Now University of Florida researchers may be one step closer to finding a safe way to spur production of the missing protein in individuals with the most common form of the hereditary bleeding disorder. Using a dormant strand of DNA which has existed in catch an incredible number of years quietly, the researchers changed the faulty gene in charge of the disease in neonatal mice, according to findings published online this month in the journal Molecular Therapy.Arteries: The pied piper for developing nerve cells Researchers in Johns Hopkins can see that arteries in the top can guide growing face nerve cells with blood circulation pressure controlling proteins. The results, which suggest that arteries throughout the body may have the same power of persuasion over many nerves, are released this week in Character.D., a professor of neuroscience at investigator and Hopkins of the Howard Hughes Medical Institute. The SCG sits in a Y-like branching stage of the bloodstream vessel in the throat that supplies the top with bloodstream, the carotid artery. In the developing embryo, nerve projections grow from the SCG and grow along among the two branches of the carotid artery; the nerves that develop along the inner carotid innervate the optical eye and mouth among various other head structures, and those that develop along the exterior carotid innervate the salivary glands.
