1 OATP1B3-1B7 a novel Organic Anion Transporting Polypeptide is modulated by FXR ligands and transports bile acids. Bile Acids and Salts solute carrier organic anion transporter family member 1B3 Homo sapiens
2 Applying a heterologous expression system we showed that several bile acids interact with OATP1B3-1B7 and that taurocholic acid and lithocholic acid are OATP1B3-1B7 substrates. Bile Acids and Salts solute carrier organic anion transporter family member 1B3 Homo sapiens
3 In accordance are our findings showing that the OATP1B3-1B7 inhibitor bromsulphthalein significantly reduced uptake of bile acids into human liver microsomes. Bile Acids and Salts solute carrier organic anion transporter family member 1B3 Homo sapiens
4 Taken together we report that OATP1B3-1B7 transcription can be modulated with FXR agonists and antagonists and that OATP1B3-1B7 transports bile acids. Bile Acids and Salts solute carrier organic anion transporter family member 1B3 Homo sapiens
