Bile flow is rapidly and markedly reduced in hepatic inflammation, correlating with
suppression of critical hepatic bile acid transporter gene expression, including the principal
hepatic bile acid importer, the Na+/taurocholate co-transporting polypeptide (Ntcp, Slc10a1).
Endotoxin treatment of rats and interleukin-1β (IL-1β) treatment of liver-derived HepG2 cells
leads to a marked decline in the nuclear binding activity of a main Ntcp gene regulator, the
nuclear receptor heterodimer retinoid X receptor: retinoic acid receptor (RXR: RAR). How IL …
