These associations have suggested the hy-pothesis that alterations in either specific bile salt re-ceptors or membranelipid composition are important determinants of maximum bile salt transport. How-ever, these correlations have 2017-04-20 2006-09-01 Functional Expression Cloning and Characterization of the Hepatocyte Na^+/Bile Acid Cotransport System The system operates by a sodium ion cotransport mechanism, and it functions in maintaining a normal enterohepatic circulation of bile salts. Analysis of structure-activity data allows us to depict our hypothesis for the interaction of the bile salt and Na with the membranal recognition site of this transport … 1991-12-01 2004-12-01 Figure 1. Bile salt transporters in human liver and intestine. At the basolateral hepatocyte membrane, the major uptake system for con-jugated bile salts is the Na -dependent bile salt transporter NTCP (SLC10A1).

The pre-S1 domain of the large HBsAg protein promotes attachment and entry of HBV into the hepatocyte via liver cell–specific receptor recently identified as Na (sodium) taurocholate cotransporting polypeptide (NTCP), which is an integral membrane protein used in bile acid transport. 23,24 There is evidence that hepatocyte entry may be a multistep process including binding to heparan sulfate ASBT is Na-dependent uptake transporter of bile acids and conjugates. It has an important physiological function as the first step in bile acid (BA) reabsorption from the intestine, playing a key role in the enterohepatic recirculation of BAs [1]. Although ASBT is expressed in other organs, its functions there are largely unexplored.

We characterized expression and activity of the bile salt transporters Na(+)/taurocholate (TC) cotransporting polypeptide (Ntcp), and bile salt export pump (Bsep), and the expression of organic anion transporting polypeptides 1 and 2 (Oatp1 and 2) and multidrug resistance associated protein-2 (Mrp2) in pregnancy and throughout lactation in rats.

In contrast, recent expression studies in mammalian cell lines have suggested that the cloned rat liver Na(+)-taurocholate cotransporting polypeptide (Ntcp) may transport only taurocholate. 1 ways to abbreviate Na(+)-bile Salt Co-transporter. How to abbreviate Na(+)-bile Salt Co-transporter? Get the most popular abbreviation for Na(+)-bile Salt Co-transporter updated in 2021 1992-08-01 The Na+/bile salt co-transporter of the pig ileal brush border membrane has been expressed in Xenopus laevis oocytes. Injection of pig ileal poly (A)+ RNA into oocytes resulted in the functional expression of an Na(+)-gradient-stimulated taurocholate uptake within 2-5 days. The expressed Na(+)-dependent taurocholate uptake exhibited saturation kinetics (apparent Km 2021-04-01 bile acid moieties (GI and G2) are tethered together via a spacer, X, and where one of the two bile acid moieties carries a photoactivatable group. These photoblockers specifically interact with the ileal Na '/ bile-salt-cotransport system as demonstrated by a concentration-dependent inhibition of … The bile salt pool undergoes an enterohepatic circulation that is regulated by distinct bile salt transport proteins, including the canalicular bile salt export pump BSEP (ABCB11), the ileal Na + -dependent bile salt transporter ISBT (SLC10A2), and the hepatic sinusoidal Na + - taurocholate cotransporting polypeptide NTCP (SLC10A1).

Hepatocellular bile salt uptake is mediated predominantly by the Na + -taurocholate cotransport proteins Ntcp (rodents) and NTCP (humans) and by the Na + -independent organic anion-transporting polypeptides Oatp1, Oatp2, and Oatp4 (rodents) and OATP-C (humans).
