A Substitute for Dystrophin: Why Utrophin Fails

Abstract

Each year 1 in 3500 males in the United States are born with Muscular Dystrophy (MD). In serious cases this disease is marked by heavily atrophied musculature, mental impairment, cardiomyopathy, and a shortened lifespan (~20 years). Currently, there is no cure for this debilitating disease and treatment options remain abysmal. Knowing how utrophin fails to replace dystrophin has potential for introducing factors that could fix this failure. That is part of the future of where this project is headed in terms of drug design and possible implications that could be had for disease treatment. This is one of the first projects that looks into the thermodynamics and molecular dynamics of these proteins to find how they function as little is still known about the way in which dystrophin transduces force and what role utrophin plays.
