In Duchenne muscular dystrophy, muscle cells die as a result of suffering many tiny membrane ruptures. A compound that increases membrane resealing can protect heart muscle cells from these effects.

Degenerative muscle diseases are usually the result of defects in the cytoskeleton, the cell's internal scaffolding. This structure normally shields muscle cells from mechanical stress, protecting their membranes from tearing.
