Xenobiotic receptor knockout mice.
Administration 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 activation by the diverse group of peroxisome proliferators. These receptors may also have critical roles in development or physiological homeostasis in addition to their abilities to allow animals to interact with exogenous chemicals or xenobiotics. To explore the function of AHR and PPAR alpha and to determine whether they participate in the adverse effects of dioxins and peroxisome proliferators, gene knockout mice were developed.
