Generating Customized Transgene Landing Sites and Multi-Transgene Arrays in Drosophila Using phiC31 Integrase
Transgenesis in numerous eukaryotes has been facilitated by the use of site-specific integrases to stably insert transgenes at predefined genomic positions (landing sites). However, the utility of integrase-mediated transgenesis in any system is constrained by the limited number and variable expression properties of available landing sites. By exploiting the nonstandard recombination activity e...
متن کاملphiC31 integrase confers genomic integration and long-term transgene expression in rat retina.
PURPOSE Gene therapy has shown promise in animal models of retinal disease, with the most success achieved to date with viral vectors used for gene delivery. Viral vectors, however, have side effects and limitations and are difficult to manufacture. The present study was conducted in an attempt to develop a novel system for long-term gene transfer in rat retinal pigment epithelium (RPE), by usi...
متن کاملUsing translational enhancers to increase transgene expression in Drosophila.
The ability to specify the expression levels of exogenous genes inserted in the genomes of transgenic animals is critical for the success of a wide variety of experimental manipulations. Protein production can be regulated at the level of transcription, mRNA transport, mRNA half-life, or translation efficiency. In this report, we show that several well-characterized sequence elements derived fr...
متن کاملIdentification of a Specific Pseudo attP Site for Phage PhiC31 Integrase in Bovine Genome
Background: PhiC31 integrase system provides a new platform in various felid of research, mainly in gene therapy and creation of transgenic animals. This system enables integration of exogenous DNA into preferred locations in mammalian genomes, which results in robust, long-term expression of the integrated transgene. Objectives: Identification of a novel pseudo attP site. Materials and Methods...
متن کاملConstruction of transgenic Drosophila by using the site-specific integrase from phage phiC31.
The phiC31 integrase functions efficiently in vitro and in Escherichia coli, yeast, and mammalian cells, mediating unidirectional site-specific recombination between its attB and attP recognition sites. Here we show that this site-specific integration system also functions efficiently in Drosophila melanogaster in cultured cells and in embryos. Intramolecular recombination in S2 cells on transf...
