Metformin 124-133 solute carrier family 19 member 3 Homo sapiens 159-164 35090865-3 2022 Uptake studies with MDCKII cells expressing OCT3, PMAT, THTR2 or SERT confirmed that metformin is a substrate of these transporters. Metformin 85-94 solute carrier family 19 member 3 Homo sapiens 56-61 35090865-5 2022 7-Cyclopentyl inhibited OCT3- and THTR2-mediated uptake of metformin. Metformin 59-68 solute carrier family 19 member 3 Homo sapiens 34-39 35090865-6 2022 AG835, thiamine and paroxetine specifically inhibited PMAT-, THTR2- and SERT-mediated uptake of metformin, respectively. Metformin 96-105 solute carrier family 19 member 3 Homo sapiens 61-66 35090865-7 2022 Using these inhibitors, the relative contributions of OCT3, PMAT, THTR2, SERT, OCTN2 and others to the intestinal permeation of metformin across Caco-2 cells were estimated to be 9.77%, 9.68%, 22.2%, 1.52%, 0% and 0.66%, respectively. Metformin 128-137 solute carrier family 19 member 3 Homo sapiens 66-71 35090865-8 2022 Concentration-dependent analysis of metformin uptake by Caco-2 cells revealed nonlinear kinetics with the similar Km(app) value to the value for THTR2. Metformin 36-45 solute carrier family 19 member 3 Homo sapiens 145-150 35090865-10 2022 The present study indicated that THTR2 is the major determinant of the nonlinear absorption of metformin, although multiple transport mechanisms contribute to its intestinal absorption. Metformin 95-104 solute carrier family 19 member 3 Homo sapiens 33-38
