Protective effect of metformin on fibroblasts with GNE myopathy by restoring autophagic flux

A Chinese team has studied autophagic flow, which is involved in the formation of bordered vacuoles, in fibroblast cultures from people with GNE myopathy :

  • autophagic flow is impaired;
  • It is improved by metformin administration;
  • the cellular protection of fibroblasts with GNE myopathy by metformin is independent of the AMPK-mTOR signalling pathway.
