They are important animal models for studying the role of genes which have been sequenced but whose functions have not been determined. (wikipedia.org)
The elevation of the humble mouse to become many scientists' experimental animal of choice has been one of the scientific phenomena of the last two decades. (nobelprize.org)
Animal models, particularly the Fmr1 knockout mouse model, have become invaluable in exploring therapeutic approaches on an electrophysiological, behavioral, biochemical, and neuroanatomical level. (nih.gov)
Using these animal models a large body of evidence has implicated PARP-1 in the regulation of DNA repair and transcriptional activity of eukaryotic genes. (imim.es)

These CNVs were found to be significantly enriched in two classes of genes, those whose mouse orthologues, when disrupted, result in either abnormal axon or dopaminergic neuron morphologies. (ed.ac.uk)

Knockout mice also offer a biological and scientific context in which drugs and other therapies can be developed and tested. (wikipedia.org)

This produces offspring that are either white and heterozygous for the knocked out gene or grey and wildtype. (wikipedia.org)

By causing a specific gene to be inactive in the mouse, and observing any differences from normal behaviour or physiology, researchers can infer its probable function. (wikipedia.org)

TLR5-deficient mice develop spontaneous colitis and metabolic syndrome which are associated with altered gut microbiota. (wikipedia.org)
Mutations in this gene can cause mitochondrial complex I deficiencies such as Leigh syndrome. (nih.gov)
A variety of (tissue-specific) Ndufs4 knockout mouse models were developed to study the Leigh syndrome pathomechanism and intervention testing. (nih.gov)
