The objective of this work was to determine the association between miRNAs and the differentiation process of satellite cells (SC) during Duchenne and Becker muscular dystrophy. Using expression microarrays, it was found that 15 miRNAs (miR-1-2, miR-184, miR-130a, miR-106b, miR-155, miR-153-1, let-7f-2, miR-130b, let -7e, miR-141, miR-20, miR-133a-1 miR-19a, miR-183,...
