Uptake of enalapril and expression of organic anion transporting polypeptide 1 in zonal, isolated rat hepatocytes.
Sinusoidal entry is the first obligatory process preceding intracellular drug removal in liver. Transport of the angiotensin converting enzyme inhibitor enalapril (1-750 microM with [(3)H]enalapril), a substrate of Oatp1, the sodium-independent organic anion transporting polypeptide 1 cloned from rat liver, was studied in rat hepatocytes isolated from all zones of the liver (homogeneous) and fr...
متن کاملContribution of organic anion transporting polypeptide to uptake of its possible substrates into rat hepatocytes.
Organic anion transporting polypeptide (oatp1) has been cloned from rat liver as one of the transporters responsible for the hepatic uptake of ligands, and its substrate specificity has been determined. However, the contribution of oatp1 to the Na+-independent uptake of ligands into rat hepatocytes remains to be investigated. In the present study, we determined the contribution of oatp1 and exa...
متن کاملOrganic anion transporting polypeptide 1B1: a genetically polymorphic transporter of major importance for hepatic drug uptake.
The importance of membrane transporters for drug pharmacokinetics has been increasingly recognized during the last decade. Organic anion transporting polypeptide 1B1 (OATP1B1) is a genetically polymorphic influx transporter expressed on the sinusoidal membrane of human hepatocytes, and it mediates the hepatic uptake of many endogenous compounds and xenobiotics. Recent studies have demonstrated ...

Hepatic nuclear factor 1alpha inhibitor ursodeoxycholic acid influences pharmacokinetics of the organic anion transporting polypeptide 1B1 substrate rosuvastatin and bilirubin.
Expression of the organic anion transporting polypeptide 1B1 (OATP1B1) is regulated by transcription factor hepatic nuclear factor (HNF) 1alpha. The aim of this study was to investigate the effect of ursodeoxycholic acid (UDCA), an inhibitor of transcription factor HNF1alpha, on rosuvastatin and bilirubin kinetics in human healthy volunteers. Both substances are substrates of OATP1B1. Twelve su...
