Objective To observe the effect of ursodeoxycholic acid (UDCA)
and its derivative
tauroursdeoxycholic acid (TUDCA)
or rifampicin (Rif) on the expressions of membrane transporter
multidrug resistance-associate protein 3 (MRP3)
and its nuclear receptor
fetoprotein transcription factor (FTF) in HepG2 cells. Methods Both total RNA and total membrane or nuclear proteins were extracted from HepG2 cells after 48 h treatment with UDCA
TUDCA or Rif (100
100 or 10 μmol/L). The mRNA and protein expression levels of MRP3 and FTF were determined by quantitative real-time PCR and Western blot analysis. Results Both FTF and MRP3 expression was significantly induced either at mRNA or protein level by UDCA
TUDCA or Rif in HepG2 cells. Conclusion The up-regulation of hepatic MRP3 expression induced by UDCA
