objective(s): organic cation transporter 3 (oct3) as a high-capacity transporter contribute to the metabolism of metformin. the present study was conducted to determine the genotype frequencies of the variant oct3-1233g>a (rs2292334) in patients with newly diagnosed type 2 diabetes (t2d) and its relationship with response to metformin. materials and methods: this study included 150 patients wit...

The plasma membrane monoamine transporter (PMAT) belongs to the equilibrative nucleoside transporter family (solute carrier 29) and was alternatively named equilibrative nucleoside transporter 4. Previous studies from our laboratory characterized PMAT as a polyspecific organic cation transporter that minimally interacts with nucleosides. Recently, PMAT-mediated uptake of adenosine (a purine nuc...

Hepatic organic cation transport consists, in part, of carrier-mediated sinusoidal uptake stimulated by an inside-negative membrane potential and canalicular excretion driven by electroneutral organic cation/H+ exchange. Intracellular organic cation transport involves sequestration into acidified organelles, also mediated by organic cation/H+ exchange. A sinusoidal organic cation transporter ha...
