Expression Cloning of Recombinant Escherichia coli lacZ Genes Encoding Cytoplasmic and Nuclear P-galactosidase Variants
Objective(s) Nonviral vector can be an attractive alternative to gene delivery in experimental study. In spite of some advantages in comparison with the viral vectors, there are still some limitations for efficiency of gene delivery in nonviral vectors. To determine the effective expression, the recombinant Escherichia coli lacZ genes were cloned into the different variants of pcDNA3.1 and the...
متن کاملGene Expression and Pulmonary Toxicity of Chitosan-graft-Polyethylenimine as Aerosol Gene Carrier
Chitosan-graft-polyethylenimine (CHI-g-PEI) copolymer has been used for theimprovement of low transfection efficiency of chitosan. The present study aims to test thepulmonary toxicity and efficiency of CHI-g-PEI as an aerosol gene carrier. Mice were exposedto aerosol containing green-fluorescent protein (GFP)-polyethylenimine (PEI) or GFP-CHIg-PEI complexes for 30 min during the development of ...

متن کاملHyperactive PiggyBac Transposons for Sustained and Robust Liver-targeted Gene Therapy
The development of robust nonviral vectors could facilitate clinical gene therapy applications and may overcome some of the immune complications of viral vectors. Nevertheless, most nonviral gene deliver approaches typically yield only transient and/or low gene expression. To address these caveats, we have explored piggyBac transposons to correct hemophilia B by liver-directed factor IX (FIX) g...
متن کاملGene therapy based on interleukin-12 loaded chitosan nanoparticles in a mouse model of fibrosarcoma
Objective(s): Interleukin-12 (IL-12) as a cytokine has been proved to have a critical role in stimulating the immune system and has been used as immunotherapeutic agents in cancer gene therapy. Chitosan as a polymer, with high ability of binding to nucleic acids is a good candidate for gene delivery since it is biodegradable, biocompatible and non-allergenic polysaccharide. The objective of the...
