Transcription profiling of extraocular, hindlimb and cardiac muscles from dKO and MDX mice


ABSTRACT: Comparison by expression profiling of tissue from dKO (utrophin/dystrophin-deficient) and MDX mice at 8 weeks of age. Independent triplicate analyses/strain were done for extraocular, hindlimb, and cardiac muscle.

Dystrophin deficiency leads to the progressive muscle wasting disease Duchenne muscular dystrophy (DMD). Dystrophin-deficient mdx mice are characterized by skeletal muscle weakness and degeneration but they appear outwardly normal in contrast to DMD patients. Mice lacking both dystrophin and the dystrophin homolog utrophin [double knockout (dko)] have muscle degeneration similar to mdx mice, but they display clinical features similar to DMD patients. Dko limb muscles also lack postsynaptic membr  ...[more]
