摘　　要：孕烷X受体(PXR)是一类配体依赖性的核受体亚家族,可感受外源物质,被多种药物激活。PXR可转录调控多种与药物代谢相关的药物代谢酶和药物转运体的表达,参与药物代谢调控。PXR转录活性的变化可改变药物在体内的代谢过程,继而诱发潜在药物不良反应,与药物药代动力学研究和临床药物治疗密切相关,并有潜力成为防治药物介导的肝损伤和逆转化疗药物耐药的新型药物靶标。综述了目前已发现的PXR翻译后修饰及其对PXR功能调控机制的研究进展。Pregnane X receptor（PXR）, a member of the nuclear receptor superfamily, is a ligand-dependent transcription factor. As a xenobiotic receptor, PXR is activated by a wide spectrum of structurally different substrates including clinical drugs, and subsequently regulates the expression of numerous drug metabolism enzymes and drug transporters at transcriptional level. PXR is closely related to pharmacokinetic study and clinical drug effect since changes in PXR transcriptional activity will result in altered in vivo drug metabolism and cause adverse drug reactions. PXR also has the potential to be developed into a novel drug target to prevent and treat liver injury induced by clinical drugs and to reverse chemotherapy drug resistance. In this article, the progress in the regulation of PXR transcriptional activity by post-translational modifications was reviewed.
