Researchers developing new 'DNA stitch' to treat muscular dystrophy

A new therapeutic being tested is showing early promise as a more effective treatment that could help nearly half of patients with Duchenne muscular dystrophy (DMD). The treatment -- a cocktail of DNA-like molecules -- results in dramatic regrowth of a protein called dystrophin, which acts as a support beam to keep muscles strong. The protein is virtually absent in those with DMD.
