Researchers have proven that gene therapy can reverse the pathological features of muscular dystrophy in an animal model. Before, gene therapy had only been able to prevent further muscle-wasting in mice. "We expect to build on these results in the continuing search for a way to treat a horrible disease. Our results indicate that gene therapy could be used not only to halt or prevent this disease, but also to restore normal muscle function in older patients," says Dr. Jeffrey S. Chamberlain, professor of neurology at the University of Washington School of Medicine in Seattle.
Chamberlain is the senior author of the paper describing the results, which will be published in the Proceedings of the National Academy of Sciences online Early Edition the week of Sept. 16 to 20.
Duchenne muscular dystrophy is an X-linked genetic disorder that strikes one of every 3,500 newborn boys. The genetic disorder means the body does not produce the dystrophin protein, which is necessary for the structural support of muscle. Without this protein, muscles weaken to the point where the victim cannot survive. There is no specific treatment against any form of muscular dystrophy, except for supportive measures, such as physical therapy, assistive technology and corrective surgery. Boys and men with the disorder usually die from respiratory failure before they can turn 25.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
