Abstract

Duchenne Muscular Dystrophy (DMD) is an X-linked recessive genetic disease, caused by a frame-shift mutation in the dystrophin gene. Current gene therapies for DMD target dystrophin transcripts in existing skeletal and cardiac muscle, rather than adipose and fibrotic tissues. These approaches may be unable to repair muscle functionality in DMD patients who have already undergone extensive muscle damage and wasting. Thus, successful DMD therapies must consider the underlying genetic cause and pathology. Inhibition of the gene myostatin, a negative regulator of muscle growth, has been shown to ameliorate muscle loss. Here, the CRISPR-Cas9 gene-editing platform is proposed to restore dystrophin expression and inhibit myostatin as a novel gene therapy in DMD patient derived induced pluripotent stem cells. Successful CRISPR-Cas9 mediated gene editing would be determined using PCR amplification, western blot analysis, immunofluorescence staining, and off target sequence analysis in differentiated skeletal muscle cells.
