Duchenne muscle dystrophy (DMD) is a progressive degenerative disease that affects skeletal and cardiac muscles, leading to death by the age of 25 due to cardiorespiratory failure. Although there is no cure for this disease, recent gene and drug therapies are being able to slow down the progression of the disease, improving life quality and duration. The need for new biomarkers to better follow the progression of the disease and to better evaluate the effects of these new therapies is one of the main points of investigation worldwide in DMD research. We previously demonstrated positive effects of omega-3 therapy in the mdx mice model of DMD, during the early stages of the disease. These promising results motivated us to go further on omega-3 mechanisms and effects. In the present study, by using modern techniques such as metabolomics, we will search for new potential biomarkers of dystrophy in omega-3 treated-mdx mice. We aim to offer data that can support omega-3 therapy in DMD clinical trials. (AU)
