Self-inactivating Transposase Plasmids for Genetic Engineering and Gene Therapy

Platform transposase/transposon plasmid for genetic engineering applications

Download summary

Technology overview

Transposon-based gene delivery strategies offer multiple advantages over viral vector-based approaches, including reduced immunogenicity; reduced risk of insertional mutagenesis; the ability to deliver large transgenes and multiple genetic elements; and lower cost. The transposon and transposase are typically separately delivered to eliminate potential integrations of the transposase genes into the host genome. However, the two-component system leads to decreased efficiency and drives up cost and complexity. Dr. Michael Jensen and colleagues have designed a single plasmid that carries a self-inactivating transposase gene and a corresponding transposon. This system utilizes intrinsic cellular machinery to mediate self-inactivation of the transposase enzyme and improve safety. The plasmids have been validated in cell lines and primary human cells. This single component transposase system is a novel platform for non-viral gene therapy and genetic engineering.

Applications

  • Non-viral gene therapy
  • Genetic engineering

Advantages

  • Single component transposon-based, non-viral genetic engineering
  • Reduced manufacturing costs

Market overview

The global gene therapy market is expected to grow at a CAGR of 33.9% from 2018 to 2026. Though the market is dominated by viral vector-based delivery methods, unwanted immune responses associated with viral vectors constitute a major hurdle to market growth. Non-viral vector-based gene delivery has shown positive results in preclinical and clinical trials for various diseases. This segment is expected to be lucrative and projected to grow during the analysis period.
