Research Abstract |
It has been proposed that Duchenne muscular dystrophy can be treated with modification of out-of-frame mutation into in-frame mutation by inducing exon skipping. In this study the possibility to treat DMD was evaluated by seeing inducibility of exon skipping. In the previous study we showed exon 19 skipping can be induced by blocking the function of splicing enhancer sequence with antisense oligonucleotides. To apply this strategy we looked for splicing enhancer sequence in exons that are located in deletion hot spots. From exon sequence purine-rich sequence were extracted as candidate sequences for splicing enhancer sequence and splicing enhancer activity of those candidate sequences were analyzed by using Drosophilla dsx minigene. Thereby some antisense oligonucleotides were found to have an ability to induce exon skipping.
