Selection-free gene repair after adenoviral vector transduction of designer nucleases: rescue of dystrophin synthesis in DMD muscle cell populations.

ABSTRACT: Duchenne muscular dystrophy (DMD) is a fatal X-linked muscle-wasting disorder caused by mutations in the 2.4 Mb dystrophin-encoding DMD gene. The integration of gene delivery and gene editing technologies based on viral vectors and sequence-specific designer nucleases, respectively, constitutes a potential therapeutic modality for permanently repairing defective DMD alleles in patient-derived myogenic cells. Therefore, we sought to investigate the feasibility of combining adenoviral vectors (AdVs) with CRISPR/Cas9 RNA-guided nucleases (RGNs) alone or together with transcriptional activator-like effector nucleases (TALENs), for endogenous DMD repair through non-homologous end-joining (NHEJ). The strategies tested involved; incorporating small insertions or deletions at out-of-frame sequence
