Gene therapy to muscle diseases: perspective and issues on basic research

Abstract

Gene therapy was considered in the treatment of life-threatening muscular dystrophy such as Duchenne muscular dystrophy (DMD). Introduction of 6.3 kb minidystrophin cDNA using adenovirus vector into skeletal muscle of mdx mice was successful, when the recombinant adenovirus was injected during the neonatal period. Recombinant adenovirus, however, evoked strong immunological reactions, when it was injected during the adult stage. The usage of mutant adenovirus, where a full length dystrophin cDNA was inserted instead of all of adenovirus protein genes, might resolve the problems that initial generations of adenovirus vector raised. Upregulation of endogenous utrophin might also give a relief in DMD patients, since introduction of truncated utrophin gene considerably improved phenotypic expression of mdx mice, when introduced as a transgene.

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.
