Xenobiotic receptor knockout mice
Toxicology Letters, 1995Administration of certain foreign chemicals to animals elicits responses that are due to receptor-mediated activation of gene expression. Among the most well studied receptors are the Ah receptor (AHR) that binds 2,3,7,8-tetrachlorodibenzo-p-dioxin and related compounds and the peroxisome proliferator-activated receptors, PPARs, that mediate gene ...

Rescue of Angiotensinogen-Knockout Mice
Biochemical and Biophysical Research Communications, 1998Angiotensinogen, the precursor of angiotensins I and II, is a critical component of the renin-angiotensin system that plays an important role in regulating blood pressure and electrolyte homeostasis. Genetically altered mice lacking angiotensinogen (Agt-KO) showed an expected phenotype, such as marked hypotension, but unexpected ones including abnormal

Generation of dynorphin knockout mice
Molecular Brain Research, 2001The opioid system has important roles in controlling pain, reward and addiction, and is implicated in numerous other processes within and outside the nervous system, such as mood states, immune responses, and prenatal developmental processes. The effects of the opioid system are mediated by at least three ligands, enkephalin, endorphin, and dynorphin ...

Insulin Receptor Knockout Mice
Annual Review of Physiology, 2003▪ Abstract To examine the role of the insulin receptor in fuel homeostasis, we and others have carried out genetic ablation studies in mice. Mice lacking insulin receptors are born with normal features, but develop early postnatal diabetes and die of ketoacidosis.

Generating Conditional Knockout Mice
2010Gene targeting in ES cells is extensively used to generate designed mouse mutants and to study gene function in vivo. Knockout mice that harbor a null allele in their germline provide appropriate genetic models of inherited diseases and often exhibit embryonic or early postnatal lethality. To study gene function in adult mice and in selected cell types,

Generation of Conditional Knockout Mice
2014Conditional knockout mouse models are powerful tools to examine the biological and molecular function(s) of genes in specific tissues. The general procedure to generate such genetically engineered mouse models consists of three main steps. The first step is to find the appropriate genomic clone of the gene of interest and to design the cloning and ...

Genetic knockouts in mice: An update
Experientia, 1995Gene disruption technology in mammals, by homologous recombination in embryonic stem cells, is a powerful method to manipulate the mouse germ line. In the past decade it has produced a wealth of knowledge concerning neuronal development, neurodegenerative disorders and the roles of oncogenes, Hox genes and growth factors during development.

Tissue-Specific Transgenic and Knockout Mice
2006Analysis of genetically engineered mice is crucial for our understanding of the in vivo function of genes and proteins in the whole organism. This includes inactivation of a gene or the generation of specific mutations. The development of knockout and transgenic technologies in the mouse, therefore, represents a powerful tool for elucidating gene ...

Molecular Medicine Today, 1999
Gene targeting has become an extremely popular method for generating mouse models of human disease. The targeting event is carried out in vitro in pluripotent embryonic stem (ES) cells, which are then used to generate chimeric founder animals by either fusion with early-stage embryos or direct injection into donor blastocysts.
