For reasons that are not yet fully understood, the rate of homologous recombination in mouse embryonic stem (ES) cells is substantially higher than that of most other cells. Once a clone of ES cells with the correct targeting event has been identified, these cells can be used to introduced into the mouse via the process of blastocyst injection, which allows the study of gene function in the bodies of living, intact animals. Widespread use of both targeted mutagenesis and gene targeting has become possible through the development of programmable nucleases which enable the induction of a precise DSB at a desired position in … (b) Illustration of vectors and cloning steps for generation of the gene targeting (GT) vector. Gene targeting is the process of disrupting or mutating a specific genetic locus in embryonic stem (ES) cells, usually with the intention of making knock-out or knock-in mice. Technologies also now exist that allow genes to be removed not just in a whole animal, as described above, but in a subset of cells or in a particular tissue. When the Cre enzyme is present in a mouse cell in which the target gene is surrounded by loxP sites, it will cut this gene out of the chromosome. Genetics. Precise DNA rearrangements and genetic alteration of endogenous genes (gene targeting… (Aand B) Testing I-SceI efficiency ().The reporter constructs were transformed via P elements (indicated by small arrowheads) and carried the I-SceI cut site (as indicated) either (A) adjacent to a shortened version of the wild-typew + gene (indicated by the large solid arrow), or (B) flanked by a complete copy and a nonfunctional partial copy of thatw + gene. Previous studies using mTOR inhibitors have shown that mTOR targeting suppresses gene expression and cell proliferation. However, the fairly low efficiency of traditional gene targeting has limited the utility of gene targeting in the study of gene function. This allows the selection of single cells that have incorporated the DNA construct into their own chromosomes. If two chromosomes break and come together again, some genes carried by these chromosomes are exchanged, a process called crossing over.
