Functional identification of organic cation transporter 1 as an atenolol transporter sensitive to flavonoids
Atenolol, a β1-adrenergic receptor blocker, is administered orally and its intestinal absorption has recently been indicated to be mediated by carrier protein and reduced markedly by ingestion of some fruit juices, such as apple and orange juices. This could be postulated to be a problem arising from the interaction of some components of fruit juices with atenolol at a transporter involved in i...
متن کاملFunctional characteristics and tissue distribution pattern of organic cation transporter 2 (OCTN2), an organic cation/carnitine transporter.
We have demonstrated in the present study that novel organic cation transporter (OCTN) 2 is a transporter for organic cations as well as carnitine. OCTN2 transports organic cations without involving Na(+), but it transports carnitine only in the presence of Na(+). The ability to transport organic cations and carnitine is demonstrable with human, rat, and mouse OCTN2s. Na(+) does not influence t...
متن کاملA nucleoside-sensitive organic cation transporter in opossum kidney cells.
Renal secretion of organic cations and anions are pleiotropic, active processes in mammals. Some nucleosides such as deoxyadenosine (dAdo), 2-chlorodeoxyadenosine, and azidothymidine are secreted by human and rodent kidneys. Previous work (J. A. Nelson, J. F. Kuttesch, Jr., and B. H. Herbert. Biochemical Pharmacology 32: 2323-2327, 1983) indicated a role for the classic organic cation transport...
متن کاملFunctional characterization of an organic cation transporter (hOCT1) in a transiently transfected human cell line (HeLa).
Recently, a polyspecific organic cation transporter, hOCT1, was cloned from human liver. To date, limited studies examining the functional characteristics of the transporter have been performed. The purpose of the present study was to develop a mammalian expression system for hOCT1 and to characterize the interactions of various compounds with the cloned transporter. Lipofection was used to tra...
متن کاملOrganic cation transporter variation and response to smoking cessation therapies.
INTRODUCTION We evaluated chr6q25.3 organic cation transporter gene (SLC22A1, SLC22A2, SLC22A3) variation and response to smoking cessation therapies. The corresponding proteins are low-affinity transporters of choline, acetylcholine and monoamines, and smoking cessation pharmacotherapies expressed in multiple tissues. METHODS We selected 7 common polymorphisms for mega-regression analysis. W...
