Abstract
Duchenne muscular dystrophy (DMD) is a severe X-linked genetic disease affecting 1 boy out of 3500. DMD is due to the lack of a submembranous cytoskeletal protein named dystrophin, leading to the progressive degeneration of skeletal, cardiac and smooth muscle tissue. A milder form of the disease, Becker muscular dystrophy (BMD), is characterised by the presence of a semi-functional truncated dystrophin, or the full-length dystrophin at reduced level. Three different therapeutic approaches are currently under study, gene therapy, cellular therapy and pharmacological therapy. One of the chosen strategies consists of the overexpression of utrophin, a protein 80% homologous with dystrophin, and able to perform similar functions. In this review, we shall consider studies of pharmacological therapy, the aims of which can be classified in three categories: reversal of dystrophic phenotype, dystrophin expression, utrophin overexpression.
