Targeted gene integration in skeletal muscle – Muscle represents a critical tissue for gene replacement. Over 70 neuromuscular diseases are cause by genetic mutations in muscle. Designing a versatile gene therapy to address these diseases requires new approaches. We are investigating hijacking of endogenous genes for sustained gene therapy. Moreover, this approach could be used to turn muscle into a protein “factory”.

Delivery of genome editing technologies – As therapeutics, genome editing technologies hold great promise. The challenge is safe and efficient delivery to diseased tissues in the patient. We are adapting viral and non-viral delivery vehicles and assessing safety and efficiency in preclinical models of disease.
