Abstract

Duchenne muscular dystrophy (DMD) is a progressive neuromuscular disorder. Here, we show that the CD63 antigen, which is located on the surface of extracellular vesicles (EVs), is associated with increased levels of muscle-abundant miRNAs, namely myomiRs miR-1, miR-133a, and miR-206, in the sera of DMD patients and mdx mice. Furthermore, the release of EVs from the murine myoblast C2C12 cell line was found to be modulated by intracellular ceramide levels in a Ca2+-dependent manner. Next, to investigate the effects of EVs on cell survival, C2C12 myoblasts and myotubes were cultured with EVs from the sera of mdx mice or C2C12 cells overexpressing myomiRs in presence of cellular stresses. Both the exposure of C2C12 myoblasts and myotubes to EVs from the serum of mdx mice, and the overexpression of miR-133a in C2C12 cells in presence of cellular stress resulted in a significant decrease in cell death. Finally, to assess whether miRNAs regulate skeletal muscle regeneration in vivo, we intraperitoneally injected GW4869 (an inhibitor of exosome secretion) into mdx mice for 5 and 10 days. Levels of miRNAs and creatine kinase in the serum of GW4869-treated mdx mice were significantly downregulated compared with those of controls. The tibialis anterior muscles of the GW4869-treated mdx mice showed a robust decrease in Evans blue dye uptake. Collectively, these results indicate that EVs and myomiRs might protect the skeletal muscle of mdx mice from degeneration.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
