Expression of hepatic cytochrome<scp>P</scp>450 in a mouse model of ulcerative colitis changes with pathological conditions

Abstract

The capacity for metabolizing drugs that are substrates of CYP decreases during the active stage of ulcerative colitis but subsequently improves during the remission stage. This decrease in CYP expression was likely caused by the observed reduction in the levels of nuclearly localized pregnane X receptor and constitutive androstane receptor, and the increase in the production of inflammatory cytokines triggered by lipopolysaccharides.
