Expression levels of miR-1, miR-133a, and miR-206 represented by box plot in (a) exosomes or (b) exosome-depleted supernatants extracted from the serum of DMD patients and controls, and analyzed by RT-qPCR. Relative expression of miR-1, miR-133a, and miR-206 is displayed as the difference in the threshold cycle number between miRNA from exosomes or the exosome-depleted supernatant extracted from the serum of DMD patients (c) in five times dilution. Each bar represents mean ± SD. *P < 0.05 versus control by Mann–Whitney U test
