| Research Abstract |
Antisense oligonucleotides that induce exon skipping is now attracting much attention to express internally deleted-dystrophin in Duchenne muscular dystrophy(DMD). Previously, we identified antisense oligonucleotides(AO85) that could induce exon 45 skipping efficiently. We examined the ability of AO85 to induce exon 45 skipping and dystrophin expression in DMD patient-derived myocytes carrying different types of deletion mutations, as follows:exon 46-47, 46-48, 46-49, 46-51 or 46-53. The skipping efficiency was different from patients to patients. We identified the junction site of each patient with deletion mutation and examined the intronic splicing enhancers/silencers (ISEs/ISSs) in the junction site. In this study, we could not clarify the correlation between ISEs/ISSs in the junction site and exon 45 skipping efficiency.
