The dystrophin-glycoprotein complex spans the sarcolemma to provide a linkage between the subsarcolemmal cytoskeleton and the extracellular matrix in skeletal muscle. In Duchenne muscular dystrophy (DMD), the absence of dystrophin leads to a drastic reduction in all of the dystrophin-associated proteins in the sarcolemma, thus causing the disruption of the dystrophin-glycoprotein complex and the loss of the linkage to the extracellular matrix. This is presumed to lead to sarcolemmal instability which could render muscle fibers susceptible to necrosis. In DMD, a very small percentage of muscle fibers show dystrophin staining along the sarcolemma, presumably due to a second in-frame deletion in the dystrophin gene. However, the functional significance of these rare dystrophin-positive muscle fibers (revertants) in DMD has been unclear. Here we report the co-expression of the dystrophin-associated proteins with dystrophin in revertants of DMD skeletal muscle. Our results suggest that the entire dystrophin-glycoprotein complex is restored in revertants and, thus, the linkage between the subsarcolemmal cytoskeleton and the extracellular matrix is restored in these muscle fibers.
