Using a new type of drug that targets a specific genetic defect, researchers at the University of Pennsylvania School of Medicine, along with colleagues at PTC Therapeutics Inc. and the University of Massachusetts Medical School, have for the first time demonstrated restoration of muscle function in a mouse model of Duchenne's muscular dystrophy (DMD). The research appears ahead of print in an advanced online publication of Nature.
