Exon skipping for DMD
Duchenne muscular dystrophy (DMD) is a severe, progressive muscle-wasting disorder, while Becker muscular dystrophy (BMD) is milder muscle disease [1]. Both are caused by mutations in dystrophin, a protein, which stabilizes muscle fibers during contraction by linking muscle actin to the extracellular matrix. In DMD patients mutations disrupt the open reading frame, generating prematurely trunca...
متن کاملDystrophin rescue by trans-splicing: a strategy for DMD genotypes not eligible for exon skipping approaches
RNA-based therapeutic approaches using splice-switching oligonucleotides have been successfully applied to rescue dystrophin in Duchenne muscular dystrophy (DMD) preclinical models and are currently being evaluated in DMD patients. Although the modular structure of dystrophin protein tolerates internal deletions, many mutations that affect nondispensable domains of the protein require further s...
متن کاملWhat Can We Learn From Clinical Trials of Exon Skipping for DMD?
On 20 September 2013, GlaxoSmithKline (GSK) and Prosensa announced that GSK’s Phase III clinical trial (NCT01254019) of Drisapersen, an exon skipping drug for Duchenne muscular dystrophy (DMD), failed to meet the primary endpoint of a statistically significant improvement in the 6 Minute Walking Distance Test (6MWT) compared to placebo.1 On 12 November 2013, Sarepta Therapeutics announced that ...
متن کاملEndogenous Multiple Exon Skipping and Back-Splicing at the DMD Mutation Hotspot
Duchenne muscular dystrophy (DMD) is a severe muscular disorder. It was reported that multiple exon skipping (MES), targeting exon 45-55 of the DMD gene, might improve patients' symptoms because patients who have a genomic deletion of all these exons showed very mild symptoms. Thus, exon 45-55 skipping treatments for DMD have been proposed as a potential clinical cure. Herein, we detected the e...
متن کاملTherapeutic antisense-induced exon skipping in cultured muscle cells from six different DMD patients.
The dystrophin deficiency leading to the severely progressing muscle degeneration in Duchenne muscular dystrophy (DMD) patients is caused by frame-shifting mutations in the DMD gene. We are developing a reading frame correction therapy aimed at the antisense-induced skipping of targeted exons from the pre-mRNA. Despite introducing a (larger) deletion, an in-frame transcript is generated that al...
