Knockout Mouse Catalog | Cyagen APAC

Conditional knockout (cKO) mice can be used to study specific gene functions and related human diseases. Compared with traditional knockout (KO) mice, conditional knockout mice are obtained with a gene that deleted only in specific tissues or on an inducible basis. Compared with constitutively expressed gene mutations, conditional models provide greater temporal and regional control of gene expression – often serving as a more accurate model for studying human diseases.

 

What are Conditional Knockout (cKO) Mice?

Conditional knockout (cKO) mice are genetically engineered animal models in which certain gene is inactivated in a specific tissue or on an inducible basis. Researchers can understand certain gene functions through time or tissue specific deletion to study the mechanisms of human disease.

 

What Applications are Conditional Knockout Mice Used For?

Conditional knockout (cKO) mice are crucial tools for revealing gene functions, gaining proper understanding of human disease mechanisms, and verifying compound specificity. Conditional knockout (cKO) mouse models also allow precise control of gene expression for a functional protein target, providing an in vivo system to evaluate potential off-target effects of a drug.

Take, for example, Raly conditional knockout mouse - the liver-specific deletion of hnRNP Raly presents lower serum cholesterol and hepatic lipid content in the described mouse model. Further in vivo genome-wide mapping of RALY-binding pattern and interrogation of chromatin architecture have provided insights into the cooperative interactions of RALY, as well as its preferential binding patterns at gene promoter regions. DNA binding results suggest that RALY may be influencing cholesterogenesis by modulating collaborative interactions with transcriptional coactivators at the Srebp2 promoter.

 

How Are Conditional Knockout Mice Generated?

Conditional knockout (cKO) models are often referred to as ‘floxed’ models due to the use of Cre/lox system in their development. The Cre-Lox recombination system enables the generation of tissue-specific or inducible knockouts with a high level of control over the spatial and temporal expression of genes, and greatly improves the efficiency and specificity in generating conditional mouse.

Here is the workflow of Cre-Lox system:
