Abstract
A set of vectors for Cre recombinase-dependent expression of the hybrid suicidal FCU1 transgene was constructed, including a two-plasmid system wherein the FCU1 and Cre transgenes reside in separate vectors, and single-plasmid variants in which a single plasmid bears both transgenes. To improve the safety profile and specificity in cancer gene therapy applications, as well as to ensure stable propagation of plasmids in bacterial cells, the Cre/LoxP system components were optimized. A bicistronic vector with the Cre expression cassette placed between the LoxP sites unidirectionally with FCU1 cDNA resulted in higher therapeutic efficiency compared with the double-plasmid system in an enzyme-prodrug suicide cancer gene therapy scheme. Therefore, the feasibility of a single-plasmid approach in the development of cancer gene therapy with hierarchical enhancement of therapeutic transgene expression has been demonstrated.
期刊介绍：
Human Gene Therapy is the premier, multidisciplinary journal covering all aspects of gene therapy. The Journal publishes in-depth coverage of DNA, RNA, and cell therapies by delivering the latest breakthroughs in research and technologies. Human Gene Therapy provides a central forum for scientific and clinical information, including ethical, legal, regulatory, social, and commercial issues, which enables the advancement and progress of therapeutic procedures leading to improved patient outcomes, and ultimately, to curing diseases.
The Journal is divided into three parts. Human Gene Therapy, the flagship, is published 12 times per year. HGT Methods, a bimonthly journal, focuses on the applications of gene therapy to product testing and development. HGT Clinical Development, a quarterly journal, serves as a venue for publishing data relevant to the regulatory review and commercial development of cell and gene therapy products.
