Experimental LPS-induced cholestasis alters subcellular distribution and affects colocalization of Mrp2 and Bsep proteins: a quantitative colocalization study.
In humans with obstructive cholestasis, intestinal MRP2 protein expression was reduced to 27.3% +/- 20.3% of control patients; this reduction correlated with the duration of cholestasis and was reversible after reconstitution of bile flow by stenting of the common bile duct.
Neither cholestasis nor Bsep internalization occurred in TR- rats lacking Mrp2.DBcAMP (20 micromol/kg i.v.) partially prevented the decrease in bile flow and BS output and substantially prevented E217G-induced Bsep internalization.
Exploration of Hepatoprotective Effect of Gentiopicroside on Alpha-Naphthylisothiocyanate-Induced Cholestatic Liver Injury in Rats by Comprehensive Proteomic and Metabolomic Signatures.
Taken together, 18b-GA confers hepatoprotection against ANIT-induced cholestasis by activating FXR through Sirt1, which promotes gene expression of the efflux transporter, and consequently attenuates dysregulation of bile acid homeostasis in hepatocyte compartments.
The ileum-liver Farnesoid X Receptor signaling axis mediates the compensatory mechanism of 17α-ethynylestradiol-induced cholestasis via increasing hepatic biosynthesis of chenodeoxycholic acids in rats.
Our data suggest that the adenovirus-mediated hepatocyte hAQP1 expression improves LPS-induced cholestasis in rats by stimulating the BSEP/ABCB11-mediated biliary bile acid excretion; a finding that might contribute to the understanding and treatment of sepsis-associated cholestatic diseases.
We investigated IGF1 isoforms in rat hepatocytes and cholangiocytes and evaluated their involvement in cell proliferation or damage induced by experimental cholestasis (bile duct ligation, BDL) or hydrophobic bile salts.
These results indicate that early- and late-stage cholestasis affects CYP3A-mediated drug metabolism differently, probably as consequence of the different activation of PXR and CAR.
