The loss of transgene expression has been a major obstacle to the development of nonviral vectors for the treatment of human diseases. We previously demonstrated that bacterial DNA linked to a mammalian expression cassette resulted in transcriptional silencing of the transgene in vivo. To confirm these studies and develop a means to produce a robust DNA vector that is not silenced in vivo, we d...

The domestic pig is an important "dual purpose" animal model for agricultural and biomedical applications. There is an emerging consensus in the biomedical community for the use of large animal models such as pigs to either serve as an alternative, or complement investigations from the mouse. However, the use of pig has not proven popular due to technical difficulties and time required in gener...

The activities of nine ubiquitous promoters (ROSA26, CAG, CMV, CMVd1, UbC, EF1α, PGK, chicken β-actin and MC1) have been quantified and compared in mouse embryonic stem cells. To avoid the high variation in transgene expression which results from uncontrolled copy number and chromosomal position effects when using random insertion based transgenic approaches, we have adopted a PhiC31 integrase ...

The pig is an ideal large animal model for genetic engineering applications. A relatively short gestation interval and large litter size makes the pig a conducive model for generating and propagating genetic modifications. The domestic pig also shares close similarity in anatomy, physiology, size, and life expectancy, making it an ideal animal for modeling human diseases. Often, however, the te...

Background: Improving the performance of HIV diagnosis assays is one of the most important ways to reduce HIV transmission. Because of the high mutation rate of HIV, it is critical to use the conserved proteins to develop diagnostic immunoassay methods. Because integrase is one of the most conserved proteins of HIV, it may be a good target for this purpose. In this paper cloning, purification a...

Protein-protein interaction (PPI) network maintains proper function of all organisms. Simple high-throughput technologies are desperately needed to delineate the landscape of PPI networks. While recent state-of-the-art yeast two-hybrid (Y2H) systems improved screening efficiency, either individual colony isolation, library preparation arrays, gene barcoding or massive sequencing are still requi...

Significant advances in genomics underscore the importance of targeted mutagenesis for gene function analysis. Here we have developed a scheme for long-range targeted manipulation of genes in the Drosophila genome. Utilizing an attP attachment site for the phiC31 integrase previously targeted to the nbs gene, we integrated an 80-kb genomic fragment at its endogenous locus to generate a tandem d...

The integrase from the Streptomyces phage (phi)C31 is a member of the serine recombinase family of site-specific recombinases and is fundamentally different from that of lambda or its relatives. Moreover, (phi)C31 int/attP is used widely as an essential component of integration vectors (such as pSET152) employed in the genetic analysis of Streptomyces species. phiC31 or integrating plasmids con...

We describe a transgenesis platform for Drosophila melanogaster that integrates three recently developed technologies: a conditionally amplifiable bacterial artificial chromosome (BAC), recombineering, and bacteriophage PhiC31-mediated transgenesis. The BAC is maintained at low copy number, facilitating plasmid maintenance and recombineering, but is induced to high copy number for plasmid isola...
