Cre (ERT2) Inducible Mouse Model. Besides the generation of the inducible knockout mice of interest (Section 3.1.2), it is highly recommended to validate the recombination properties of the Cre mouse, that is, the sites of recombinase expression and tamoxifen-dependent Cre activity, by crossing it … Christian Günschmann. Department of Pharmacology and Therapeutics, Porto, Portugal. Department of Dermatology, Cologne Excellence Cluster on Cellular Stress Responses in Aging-Associated Diseases (CECAD), Joseph-Stelzmann-Strasse 26, 50931 Cologne, Germany. The LoxP mouse line has two loxP elements flanking the entire or part of the gene of interest, giving the loxP mouse defined gene(s) to be edited. Besides the generation of the inducible knockout mice of interest (Section 3.1.2), it is highly recommended to validate the recombinationproperties of the Cre mouse, that is, the sites of recombinase expression and tamoxifen-dependent Cre activity, by crossing it … Nuno Pires. BIAL, Department of Research and Development, Porto, Portugal. The inducible analog of Cre is ERT2-Cre-ERT2, in which Cre activity will only be observed with the introduction of Tamoxifen. Transgenic Mouse Technology in Skin Biology: Inducible Gene Knockout in Mice. With the Tet-OFF system, you can administer doxycycline to the mice from birth until the time you want Cre activity to knockout your target gene. Correspondence. Salt‐inducible kinase 1 knockout mice show a salt‐retaining phenotype and salt‐sensitive hypertension (1136.5) Maria Pinho. Another serious limitation is a lack of evolutive adaptations in knockout model that might occur in wild type animals after they naturally mutate. By crossing PTEN conditional knockout mice with transgenic mice expressing a tamoxifen-inducible Cre-ER(T) under the control of a chicken actin promoter, we have generated a tamoxifen-inducible mouse model that allows temporal control of PTEN deletion. Wilcox AG, Vizor L, Parsons MJ(1), Banks G, Nolan PM. Christian Günschmann. Author information: (1)1 Vertex Pharmaceuticals, Boston, MA 02210. We designed multiple drug-inducible sgRNA expression vectors and measured their activities using an EGFP gene disruption assay in 11 human and mouse cell lines. mouse’’). Conditional/inducible mutation approaches are then required that first allow the mouse to develop and mature normally prior to ablation of the gene of interest. By crossing PTEN conditional knockout mice with transgenic mice expressing a tamoxifen-inducible Cre-ER T under the control of a chicken actin promoter, we have generated a tamoxifen-inducible mouse model that allows temporal control of PTEN deletion.
