A- and B-utrophin Have Different Expression Patterns and Are Differentially Up-regulated in mdx Muscle

Abstract excerpt

Duchenne muscular dystrophy (DMD) is a fatal childhood disease caused by mutations that abolish the expression of dystrophin in muscle. Utrophin is a paralogue of dystrophin and can functionally replace it in skeletal muscle. A method to induce utrophin up-regulation in muscle should therefore be therapeutically useful in DMD. We have previously shown that there are two full-length utrophin mRNA species: A and B....
