What is a Cre transgenic mouse?
A Cre mouse contains a Cre recombinase transgene under the direction of a tissue-specific promoter; a loxP mouse contains two loxP sites that flank a genomic segment of interest, the “floxed” locus. Typically, Cre and loxP mice are produced by using transgenic technology (Nagy 2000).
How is Cre mouse generated?
The simplest Cre-lox system to generate a knockout (KO) mouse model has two components that need to be genetically engineered in the murine genome: a target sequence surrounded by loxP sites (often called a “floxed” allele) and a Cre recombinase gene controlled by a specific promoter.
What activates Cre?
Inducible Cre activation is achieved using CreER (estrogen receptor) variant, which is only activated after delivery of tamoxifen. This is done through the fusion of a mutated ligand binding domain of the estrogen receptor to the Cre recombinase, resulting in Cre becoming specifically activated by tamoxifen.
How does Cre mice work?
The Cre/lox system is one of the most powerful and versatile tools developed for mouse genetics. It gives mouse researchers sophisticated control over the location and timing of gene expression. Cre/lox is usually used to make knockout alleles, but it can also be used to activate gene expression.
How does mouse Cre work?
What are Cre mice used for?
What is Cre activity?
Cre recombinase-mediated DNA recombination is an established method for conditional control of gene expression in animal models. Regulation of its activity has been accomplished to impart spatial and/or temporal control over recombination of the target gene.
What is a Cre driver?
Cre-driver lines: A special type of transgenic mouse As different neurons have different cellular machinery to activate and express certain genes, Cre-recombinase was targeted to specific neuronal (or other brain cell types) with this in mind.
What is CRE technology?
CRE software simply refers to any web-based solution that can inform or direct commercial real estate decisions and activities. It’s a very broad tech category that’s set to grow even larger. CRE tech software is used for many purposes within the industry.
What is Cre dependent?
Cre-dependent gene expression – placing a stop codon with loxP sites on either side (often called a “lox-stop-lox” or “LSL” cassette) upstream of a gene of interest will prevent gene expression in the absence of Cre. In the presence of Cre, the stop codon is excised, and gene expression proceeds.
