The Sister of P-glycoprotein Represents the Canalicular Bile Salt Export Pump of Mammalian Liver*
Canalicular secretion of bile salts is a vital function of the vertebrate liver, yet the molecular identity of the involved ATP-dependent carrier protein has not been elucidated. We cloned the… Expand

Bile salts of vertebrates: structural variation and possible evolutionary significance[S]
Biliary bile salt composition of 677 vertebrate species (103 fish, 130 reptiles, 271 birds, 173 mammals) was determined. Bile salts were of three types: C27 bile alcohols, C27 bile acids, or C24 bile… Expand

Inhibition of Bile Acid Transport across Na+/Taurocholate Cotransporting Polypeptide (SLC10A1) and Bile Salt Export Pump (ABCB 11)-Coexpressing LLC-PK1 Cells by Cholestasis-Inducing Drugs
Vectorial transport of bile acids across hepatocytes is a major driving force for bile flow, and bile acid retention in the liver causes hepatotoxicity. The basolateral and apical transporters for… Expand

Uptake of ursodeoxycholate and its conjugates by human hepatocytes: role of Na(+)-taurocholate cotransporting polypeptide (NTCP), organic anion transporting polypeptide (OATP) 1B1 (OATP-C), and…
Ursodeoxycholate (UDCA) is widely used for the treatment of cholestatic liver disease. After oral administration, UDCA is absorbed, taken up efficiently by hepatocytes, and conjugated mainly with… Expand
