Alterations of Histone Modifications Contribute to Pregnane X Receptor-Mediated Induction of CYP3A4 by Rifampicin.

abstract：:The aryl hydrocarbon receptor (AhR) is a transcriptional enhancer that is activated by the binding of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and related toxic xenobiotics, as well as some naturally occurring compounds. Ligand binding initiates 1) dissociation of the ligand-bound monomeric AhR from the ligand-unocc...
