Washington, November 3: Rockefeller University scientists say that an overlooked and undervalued protein, sarcospan, may ameliorate the most severe form of muscular dystrophy if added to muscle cells.

The researchers write in their study report that in Duchenne muscular dystrophy (DMD), the mutated dystrophin protein fails to anchor correctly to its membrane glycoprotein complex, causing muscle cells to experience severe contraction-induced damage.

The say that sarcospan is part of the anchoring complex, but because mice without sarcospan do not seem any worse for its absence, it has not received much attention to date.
