摘要: Duchenne muscular dystrophy (DMD) is a severe muscle-wasting disease generally caused by reading frame disrupting mutations in the DMD gene resulting loss of functional dystrophin protein. The can be restored antisense oligonucleotide (AON)-mediated exon skipping, allowing production internally deleted, but partially proteins as found less Becker dystrophy. Due to genetic variation between species, mouse models with murine genes are limited use test and further optimize human specific AONs vivo. To address this we have generated del52hDMD/mdx mouse. This model carries both genes. However, expression abolished due stop mutation 23, while deletion 52. model, like mdx, shows signs muscle on histological level phenotypically mild impairment. Local administration vivo morpholinos induces skipping restoration these mice. Depending number mismatches, occasional Dmd gene, albeit at low levels, could observed. Unlike previous models, enables analysis targeting 51 or 53 RNA protein quality function. Therefore, it will valuable tool for optimizing genome editing approaches DMD.
