The organic anion transporting polypeptides (human: OATP; other: Oatp) form a mammalian transporter superfamily that mediates the transport of structurally unrelated compounds across the cell membrane. Members in this superfamily participate in the absorption, distribution and excretion of many endogenous and exogenous substances including a number of medications and environmental toxicants. Po...

In Africa, Sutherlandia frutescens is a popular medicinal herb widely consumed by people living with human immunodeficiency virus/ AIDS. Concomitant use with antiretroviral drugs has generated concerns of herb-drug interaction (HDI). This study investigated the inhibitory effects of the crude extracts of S. frutescens on the major cytochrome P450 isozymes with the use of pooled human liver micr...

BACKGROUND & OBJECTIVES Organic anion transport protein 1B1 (OATP1B1) is a major transporter protein for bile salt uptake in the enterohepatic circulation of bile salts. As the role of SLCO1B1 gene (encodes OATP1B1 or liver specific transporter-1) 388 A>G polymorphism in susceptibility towards gallstone disease is unclear the prevalence of this polymorphism in healthy north Indian population wa...

Organic anion transporting polypeptides (rodents, Oatps; human, OATPs) are primarily involved in the transmembrane transportation of a wide range of endogenous and exogenous compounds. Multiple mouse Oatp1 isoforms are closely located on chromosome 6, where each isoform shows distinct tissue distribution; Oatp1b2, Oatp1a6, and Oatp1c1 are expressed exclusively in the liver, kidney, and cerebrum...

Organic anion-transporting polypeptides (OATP) 1B1 and 1B3 are widely acknowledged as important and rate-limiting to the hepatic uptake of many drugs in clinical use. Accordingly, to better understand the in vivo relevance of OATP1B transporters, targeted disruption of murine Slco1b2 gene was carried out. It is noteworthy that Slco1b2( / ) mice were fertile, developed normally, and exhibited no...
