Expression and pharmacological profile of the human organic cation transporters hOCT1, hOCT2 and hOCT3.
1. Organic cation transporters (OCTs) are involved in the elimination of monoamines and cationic xenobiotics. To examine whether some cell lines express several different OCTs, we investigated seven human cell lines for the mRNA expression pattern of the human (h) transporters hOCT1, hOCT2 and hOCT3. hOCT1 mRNA was found in all cell lines, six additionally expressed hOCT3 and only two cell line...
متن کاملMolecular determinants of substrate/inhibitor binding to the human and rabbit renal organic cation transporters hOCT2 and rbOCT2.
Organic cation transporters are important for the elimination of many drugs and toxins from the body. In the present study, substrate-transporter interactions were investigated in Chinese hamster ovary cells stably transfected with either the human or rabbit orthologs of the principal organic cation transporter in the kidney, OCT2. IC(50) values, ranging from 0.04 muM to >3 mM, for inhibition o...
متن کاملHuman organic anion transporters and human organic cation transporters mediate renal transport of prostaglandins.
Prostaglandin E(2) (PGE(2)) and prostaglandin F(2 alpha) (PGF(2 alpha)) have been used for the induction of labor and the termination of pregnancy. Renal excretion is shown to be an important pathway for the elimination of PGE(2) and PGF(2 alpha). The purpose of this study was to elucidate the molecular mechanism of renal PGE(2) and PGF(2 alpha) transport using cells stably expressing human org...
متن کاملHuman organic anion transporters and human organic cation transporters mediate renal antiviral transport.
Renal excretion is an important elimination pathway for antiviral agents, such as acyclovir (ACV), ganciclovir (GCV), and zidovudine (AZT). The purpose of this study was to elucidate the molecular mechanisms of renal ACV, GCV, and AZT transport using cells stably expressing human organic anion transporter 1 (hOAT1), hOAT2, hOAT3, and hOAT4, and human organic cation transporter 1 (hOCT1) and hOC...
متن کاملThe interaction of n-tetraalkylammonium compounds with a human organic cation transporter, hOCT1.
Polyspecific organic cation transporters in epithelia play an important role in the elimination of many endogenous bioactive amines and therapeutically important drugs. Recently, the first human organic cation transporter (hOCT1) was cloned from liver. The purpose of the current study was to determine the effect of molecular size and hydrophobicity on the transport of organic cations by hOCT1. ...
