Autoimmune hepatitis (AIH) is a disease of unknown etiology, characterized by liver-related autoantibodies. Autoimmune hepatitis is subdivided into two major types: AIH type 1 is characterized by the detection of ANA, SMA, ANCA, anti-ASGP-R, and anti-SLA/LP. Autoimmune hepatitis type 2 is characterized to be mainly related with drug-metabolizing enzymes as(More)
The purpose of the present study was to examine simultaneously the absolute protein amounts of 152 membrane and membrane-associated proteins, including 30 metabolizing enzymes and 107 transporters, in pooled microsomal fractions of human liver, kidney, and intestine by means of SWATH-MS with stable isotope-labeled internal standard peptides, and to compare(More)
Autoimmune hepatitis type 1 (AIH-1) is characterized by the detection of smooth muscle autoantibodies, antinuclear antibodies and antineutrophil cytoplasmic autoantibodies, and AIH-2 is characterized by the presence of autoantibodies against LKM, which contain drug-metabolizing enzymes. In this study, we measured the levels of drug-metabolizing enzymes in(More)
Dysbiosis (alteration of intestinal flora) is associated with various host physiologies, including diseases. The purpose of this study was to clarify the effect of dysbiosis on protein expression levels in mouse liver and kidney by quantitative proteomic analysis, focusing in particular on drug-metabolizing enzymes and transporters in order to investigate(More)
UDP-glucuronosyltransferase 1A1 (UGT1A1) plays a key role to conjugate bilirubin and prevent jaundice. There are two major elements for the induction of UGT1A1, such as PBREM (−3483/−3194), far from the promoter site, and HNF1 (−75/−63), near to the promoter site. In a previous report, we showed that the proximal HNF1 site is essential for the induction of(More)
During the course of the study of UGT1A1 induction by bilirubin, we could not detect the induction of the reporter gene (−3174/+14) of human UGT1A1 in HepG2 by bilirubin (Mol. Biol. Rep. 31: 151–158 (2004)). In this report, we show the finding of the induction of the reporter gene of UGT1A1 by cortisol at 1 μM, a major natural cortico-steroid, with human(More)
Previous study showed noinduction of the reporter gene (-3174/+14) of UGT1A1 in HepG2 by bilirubin, but induction by dexamethasone (DEX). This induction was enhanced seven-fold by the co-expression of human glucocorticoid receptor (GR) and was inhibited by a GR antagonist, RU486, indicating stimulation by DEX-GR. Meanwhile, we could not detect stimulation(More)
