Mutations in the dystrophin gene can lead to muscular dystrophy. The dystrophin-associated complex of proteins that was first characterized at the muscle cell membrane is now also being found in other cell types.

this study determines the value of linkage analysis using six rflp markers for carrier detection and prenatal diagnosis in familial dmd/bmd cases and their family members for the first time in the iranian population. we studied the dystrophin gene in 33 unrelated patients with clinical diagnosis of dmd or bmd. subsequently, we determined the rate of heterozygosity for six intragenic rflp marker...

Dystrophin, the protein product of the Duchenne muscular dystrophy (DMD) gene, is a cytoskeletal protein tightly associated with a large oligomeric complex of sarcolemmal glycoproteins including dystroglycan, which provides a linkage to the extracellular matrix component, laminin. In DMD, the absence of dystrophin leads to a drastic reduction in all of the dystrophin-associated proteins, causin...

Dystrophin, the protein product of the Duchenne muscular dystrophy (DMD) gene locus, is expressed on the muscle fiber surface. One key to further understanding of the cellular function of dystrophin would be extended knowledge about its subcellular organization. We have shown that dystrophin molecules are not uniformly distributed over the humen, rat, and mouse skeletal muscle fiber surface usi...

Duchenne muscular dystrophy (DMD) is an incurable neuromuscular degenerative disease, caused by a mutation in the dystrophin gene. Mdx mice recapitulate DMD features. Here we show that injection of wild-type (WT) embryonic stem cells (ESCs) into mdx blastocysts produces mice with improved pathology and function. A small fraction of WT ESCs incorporates into the mdx mouse nonuniformly to upregul...

Dystrophin, the protein product of the human Duchenne muscular dystrophy gene, exists in skeletal muscle as a large oligomeric complex that contains four glycoproteins of 156, 50, 43, and 35 kD and a protein of 59 kD. Here, we investigated the relative abundance of each of the components of the dystrophin-glycoprotein complex in skeletal muscle from normal and mdx mice, which are missing dystro...

Duchenne muscular dystrophy (DMD) is the most common and severe inherited neuromuscular disorder. DMD is caused by mutations in the gene encoding the dystrophin protein in muscle fibers. Dystrophin was originally proposed to be a structural protein that protected the sarcolemma from stresses produced during contractions. However, more recently, experimental evidence has revealed a far more comp...

Duchenne muscular dystrophy (DMD) is caused mostly by internal deletions in the gene for dystrophin, a protein essential for maintaining muscle cell membrane integrity. These deletions abrogate the reading frame and the lack of dystrophin results in progressive muscle deterioration. DMD patients experience progressive loss of ambulation, followed by a need for assisted ventilation, and eventual...

Duchenne muscular dystrophy is a primary muscle disease that manifests itself in young boys as a result of a defect in a gene located on the X-chromosome. This gene codes for dystrophin, a normal muscle protein that is located beneath the sarcolemma of muscle fibres. Therapies to alleviate this disease have centred on implanting normal muscle precursor cells into dystrophic fibres to compensate...
