abstractText | The mdx mouse, an animal model used to study Duchenne muscular dystrophy, has a nonsense mutation in exon 23 of the dystrophin gene which should result in a truncated protein that cannot be correctly localized at the sarcolemma of the muscle fibers. Immunohistochemical staining with antidystrophin antibodies has shown that while most of the muscle tissue is dystrophin-negative, a small percentage of muscle fibers is clearly dystrophin- positive and has somehow bypassed the primary nonsense mutation. A sensitive nested polymerase chain reaction- based examination of dystrophin gene transcripts around the mdx mutation has revealed several alternatively processed transcripts, Four mRNA species skipped the mutation in exon 23, were in-frame, and could be translated into a shorter but still functional dystrophin protein, Specific tests for these transcripts demonstrated these were also present in normal mouse muscle tissue.
