PXR(Nitrane X receptor,NR 1 I2)是核受体超家族的一员,参与哺乳动物对化学环境的反应,调节代谢酶和转运蛋白的表达。目的:总结PXR的功能及临床意义。在目前的审查中,PXR的临床意义进行了讨论,并强调使用基因工程PXR小鼠模型。小鼠模型的最新进展,包括PXR-空和PXR-人源化小鼠,提供了体内工具,用于评估PXR的生理功能及其在控制异生物质代谢和转运中的作用。通过使用PXR敲除和人源化小鼠模型,发现PXR影响药物-药物相互作用、肝脂肪变性以及维生素D、胆汁酸和类固醇激素的稳态。PXR也被证明会影响炎症性肠病。
The pregnane X receptor (PXR; NR1I2), a member of the nuclear receptor superfamily, regulates the expression of metabolic enzymes and transporters involved in the response of mammals to their chemical environment. To summarize the functions and clinical implications of PXR. In the current review, the clinical implications of PXR are discussed, and the use of genetically engineered PXR mouse models is highlighted. Recent advances in mouse models, including Pxr-null and PXR-humanized mice, provide in vivo tools for evaluating the physiological functions of PXR and its role in controlling xenobiotic metabolism and transport. By using the PXR knockout and humanized mouse models, PXR was found to influence drug-drug interactions, hepatic steatosis, and the homeostasis of vitamin D, bile acids and steroid hormones. PXR was also shown to influence inflammatory bowel diseases.
