Summary: In this protocol, we describe how to utilize the unnatural amino acid (UAA) incorporation system to read through endogenous premature termination codons in a Duchenne muscular dystrophy mouse model. We detail how to screen and optimize tRNA-enzyme pairs for efficient UAA incorporation, deliver the system intraperitoneally or intramuscularly in pathogenic mice by an adeno-associated viral (AAV) vector, and evaluate the restoration of endogenous dystrophin and increase in muscle strength after AAV injection.For complete details on the use and execution of this protocol, please refer to Shi et al. (2021).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
