Readthrough mutation example
WebHere, we combined rAAV-based gene delivery and sup-tRNA-mediated PTC readthrough to develop AAV-NoSTOP, which overcame a pathogenic nonsense mutation when administered in vivo via synergistic PTC readthrough and NMD inhibition. Importantly, AAV-NoSTOP demonstrated a good safety profile and stable efficacy more than six months after …
