Pregnane X receptor and human malignancy.
Histology and histopathology, 2013 Pregnane X Receptor (PXR) is a member of the nuclear receptor superfamily, expressed in liver, intestine and other tissues. PXR exerts transcriptional regulation by binding to its DNA response elements as an heterodimer with Retinoid X Receptor (RXR).

Evolution of pharmacologic specificity in the pregnane X receptor
BMC Evolutionary Biology, 2008 Background The pregnane X receptor (PXR) shows the highest degree of cross-species sequence diversity of any of the vertebrate nuclear hormone receptors. In this study, we determined the pharmacophores for activation of human, mouse, rat, rabbit, chicken,

Pregnane X receptor and drug-induced liver injury [PDF]
Expert Opinion on Drug Metabolism & Toxicology, 2014 The liver plays a central role in transforming and clearing foreign substances. The continuous exposure of the liver to xenobiotics sometimes leads to impaired liver function, referred to as drug-induced liver injury (DILI). The pregnane X receptor (PXR) tightly regulates the expression of genes in the hepatic drug-clearance system and its undesired ...
