Multiplexed transposon-mediated stable gene transfer in human cells.
Generation of cultured human cells stably expressing one or more recombinant gene sequences is a widely used approach in biomedical research, biotechnology, and drug development. Conventional methods are not efficient and have severe limitations especially when engineering cells to coexpress multiple transgenes or multiprotein complexes. In this report, we harnessed the highly efficient, nonvir...
متن کاملpiggyBac Transposon-mediated Long-term Gene Expression in Mice
Transposons are promising systems for somatic gene integration because they can not only integrate exogenous genes efficiently, but also be delivered to a variety of organs using a range of transfection methods. piggyBac (PB) transposon has a high transposability in mammalian cells in vitro, and has been used for genetic and preclinical studies. However, the transposability of PB in mammalian s...
متن کاملHyperactive piggyBac gene transfer in human cells and in vivo.
We characterized a recently developed hyperactive piggyBac (pB) transposase enzyme [containing seven mutations (7pB)] for gene transfer in human cells in vitro and to somatic cells in mice in vivo. Despite a protein level expression similar to that of native pB, 7pB significantly increased the gene transfer efficiency of a neomycin resistance cassette transposon in both HEK293 and HeLa cultured...
متن کاملThe piggyBac transposon holds promise for human gene therapy.
E ver since their molecular isolation in eukaryotic organisms, transposons have been precious implements of the geneticist’s toolkit. The properties that make transposons so useful are their ability to move from one chromosomal position to another and the relatively minimal requirements for transposition to occur in the test tube and in living cells (1). In particular, transposons can be harnes...
متن کاملpiggyBac transposon system modification of primary human T cells.
The piggyBac transposon system is naturally active, originally derived from the cabbage looper moth. This non-viral system is plasmid based, most commonly utilizing two plasmids with one expressing the piggyBac transposase enzyme and a transposon plasmid harboring the gene(s) of interest between inverted repeat elements which are required for gene transfer activity. PiggyBac mediates gene trans...
