In this study, we compared the metabolic effects of TCPOBOP using lipidomic, transcriptomic, and proteomic analyzes in wild-type and humanized CAR-PXR-CYP3A4/3A7 mice. In the humanized mouse model, human CAR retains its constitutive activity in metabolism regulation; however, it is not significantly activated by TCPOBOB.

WebPanaxytriol can upregulate CYP3A4 expression by promoting PXR dissociation from HSP90α and enhancing PXR binding to RXRα in HepG2 cells and Huh-7 cells. At high concentrations of panaxytriol, CAR also participates in the induction of CYP3A4 through a similar mechanism. However, in general, CAR antag … WebAug 1, 2016 · The constitutive androstane receptor (CAR) and pregnane X receptor (PXR) regulate various genes involved in xenobiotics and drug metabolism. In many cases, CAR/PXR share ligands termed dual ligands of CAR/PXR. It is difficult to investigate the effect of CAR/PXR dual ligands in cell lines because CAR and PXR expression is …
WebDec 4, 2024 · CYP3A4 is a key drug-metabolizing enzyme, as it metabolizes about 50% of drugs and xenobiotics.
