Here, we investigated whether SGK1 influences structure, function and/or fibrosis of the muscles from the mdx mouse, an animal model for DMD.

Surprisingly, soleus and diaphragm muscles of mdx/sgk1 -/- mice displayed forces close to wild-type levels. Most muscle fibers of the double mutants contained central nuclei, but fibrosis was not observed in any of the tested limb and diaphragm muscles. We conclude that the sole lack of SGK1 in mouse muscle does not lead to pronounced changes in muscle structure and function.
