Kidney-specific expression of human organic cation transporter 2 (OCT2/SLC22A2) is regulated by DNA methylation.
Human organic cation transporter 2 (OCT2/SLC22A2), which is specifically expressed in the kidney, plays critical roles in the renal secretion of cationic compounds. Tissue expression and membrane localization of OCT2 are closely related to the tissue distribution, pharmacological effects, and/or adverse effects of its substrate drugs. However, the molecular mechanisms underlying the kidney-spec...
متن کاملLocalization of organic cation transporters OCT1 and OCT2 in rat kidney.
Renal excretion and reabsorption of organic cations are mediated by electrogenic and electroneutral organic cation transporters, which belong to a recently discovered family of polyspecific transporters. These transporters are electrogenic and exhibit differences in substrate specificity. In rat, the renal expression of the polyspecific cation transporters rOCT1 and rOCT2 was investigated. By i...
متن کاملProximal tubular secretion of creatinine by organic cation transporter OCT2 in cancer patients.
PURPOSE Knowledge of transporters responsible for the renal secretion of creatinine is key to a proper interpretation of serum creatinine and/or creatinine clearance as markers of renal function in cancer patients receiving chemotherapeutic agents. EXPERIMENTAL DESIGN Creatinine transport was studied in transfected HEK293 cells in vitro and in wild-type mice and age-matched organic cation tra...
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 کاملSubstrate-dependent ligand inhibition of the human organic cation transporter OCT2.
Organic cation transporter 2 (OCT2) mediates the initial step in renal secretion of organic cations: uptake from the blood, across the basolateral membrane, and into the renal proximal tubule cells. Because of its potential as a target for unwanted drug-drug interactions (DDIs), considerable attention has been directed toward understanding the basis of OCT2 selectivity. These studies typically ...
