Conservative site-specific and single-copy transgenesis in human LINE-1 elements

Genome engineering of human cells plays an important role in biotechnology and molecular medicine. In particular, insertions of functional multi-transgene cassettes into suitable endogenous sequences will lead to novel applications. Although several tools have been exploited in this context, safety issues such as cytotoxicity, insertional mutagenesis and off-target cleavage together with limita...

A Site-Specific, Single-Copy Transgenesis Strategy to Identify 5′ Regulatory Sequences of the Mouse Testis-Determining Gene Sry

The Y-chromosomal gene SRY acts as the primary trigger for male sex determination in mammalian embryos. Correct regulation of SRY is critical: aberrant timing or level of Sry expression is known to disrupt testis development in mice and we hypothesize that mutations that affect regulation of human SRY may account for some of the many cases of XY gonadal dysgenesis that currently remain unexplai...

Site-specific integrase-mediated transgenesis in mice via pronuclear injection.

Microinjection of recombinant DNA into zygotic pronuclei has been widely used for producing transgenic mice. However, with this method, the insertion site, integrity, and copy number of the transgene cannot be controlled. Here, we present an integrase-based approach to produce transgenic mice via pronuclear injection, whereby an intact single-copy transgene can be inserted into predetermined ch...

Efficient site-specific transgenesis and enhancer activity tests in medaka using PhiC31 integrase

Established transgenesis methods for fish model systems allow efficient genomic integration of transgenes. However, thus far a way of controlling copy number and integration sites has not been available, leading to variable transgene expression caused by position effects. The integration of transgenes at predefined genomic positions enables the direct comparison of different transgenes, thereby...

Single-copy transgenic mice with chosen-site integration.

We describe a general way of introducing transgenes into the mouse germ line for comparing different sequences without the complications of variation in copy number and insertion site. The method uses homologous recombination in embryonic stem (ES) cells to generate mice having a single copy of a transgene integrated into a chosen location in the genome. To test the method, a single copy murine...
