Expression of mini-dystrophin driven by the 1.35 kb MCK promoter ameliorates muscular dystrophy in fast, but not in slow muscles of transgenic mdx mice. Gentamicin fails to increase dystrophin expression in dystrophin-deficient muscle. (2003) U7 snRNAs induce correction of mutated dystrophin pre-mRNA by exon skipping. Antibody-mediated targeting of an adenovirus vector modified to contain a syn...

Duchenne muscular dystrophy (DMD)--which is caused by mutations in the dystrophin gene-is one of the most severe myopathies. Among therapeutic strategies, exon skipping allows the rescue of dystrophin synthesis through the production of a shorter but functional messenger RNA. Here, we report the identification of a microRNA--miR-31--that represses dystrophin expression by targeting its 3' untra...

Duchenne muscular dystrophy (DMD), caused by mutations at the dystrophin gene, is the most common form of muscular dystrophy. There is no cure for DMD and current therapeutic approaches to restore dystrophin expression are only partially effective. The absence of dystrophin in muscle results in dysregulation of signaling pathways, which could be targets for disease therapy and drug discovery. P...

In 1987, about 150 years after the discovery of Duchenne muscular dystrophy (DMD), its responsible gene, the dystrophin gene, was cloned by Kunkel. This was a new substance. During these 20 odd years after the cloning, our understanding on dystrophin as a component of the subsarcolemmal cytoskeleton networks and on the pathomechanisms of and experimental therapeutics for DMD has been greatly en...

We describe a partial TaqI map of the dystrophin gene, obtained mainly by analysis of 87 overlapping DMD/BMD deletions with small fragments of the dystrophin cDNA probes; exon 6 of the dystrophin gene was identified on the TaqI map using the polymerase chain reaction. The cDNA probes detect five polymorphisms with TaqI, more than with HindIII (one), BglII (four), or PstI (three). The five polym...

Dystrophin was purified from rabbit skeletal muscle by alkaline dissociation of dystrophin-glycoprotein complex which was first prepared by derivatized lectin chromatography. Dystrophin-glycoprotein complex was isolated from digitonin-solubilized rabbit skeletal muscle membranes by a novel two-step method involving succinylated wheat germ agglutinin (sWGA) chromatography and DEAE-cellulose ion ...

Background Dystrophin, an essential protein functional in the maintenance of muscle structural integrity is known to be responsible for muscle deterioration during white spot syndrome virus (WSSV) infection among prawn species. Previous studies have shown the upregulation of dystrophin protein in Macrobrachium rosenbergii (the giant freshwater prawn) upon white spot syndrome virus (WSSV) infect...

PURPOSE Duchenne muscular dystrophy is frequently associated with a reduced amplitude of b-wave under scotopic conditions in the electroretinogram. This suggests that the dystrophin gene-encoded proteins play a role in retinal neurotransmission. The abnormal neurotransmission has been attributed to altered expressions of C-terminal products of the dystrophin gene in the outer plexiform layer, w...

Defects in the dystrophin gene cause the severe degenerative muscle disorder, Duchenne muscular dystrophy (DMD). Among the gene therapy approaches to DMD under investigation, a gene editing approach using oligonucleotide vectors has yielded encouraging results. Here, we extend our studies of gene editing with self-pairing, chimeric RNA/DNA oligonucleotides (RDOs) to the use of oligodeoxynucleot...

Autologous stem cells that have been genetically modified to express dystrophin are a possible means of treating Duchenne Muscular Dystrophy (DMD). To maximize the therapeutic effect, dystrophin construct needs to contain as many functional motifs as possible, within the packaging capacity of the viral vector. Existing dystrophin constructs used for transduction of muscle stem cells do not cont...
