Viral vectors based gene therapy is often compromised by adverse immunological reactions raising safety concerns. Hence, improved design and development of non-viral vectors with strong regulatory regions is desired. We describe the design of a non-viral mammalian expression vector with the primary transgene (a truncated dystrophin gene linked with Duchenne muscular dystrophy (DMD)) named microdystrophin delR4-R23/delCT (MD1) is under the transcriptional control of elements of desmin locus control region (DES-LCR). The designed vector, named as DES-LCR/MD1-EGFP, was constructed by cloning two fragments into the pBluescript backbone. Fragment 1 contains DES-LCR enhancer and DES-LCR promoter region while fragment 2 contains MD1 transgene and reporter EGFP (enhanced green fluorescent protein) gene separated by linker P2A (2A peptide). This vector design provides a framework for strong regulation with nonviral features. This design forms the foundation for application in conditions linked to multisystem diseases.
