Metformin enters and leaves cells mainly through organic cationic transporters and multidrug and toxin extrusion transporters.
“Being a hydrophilic compound charged positively at physiological pH, metformin enters and leaves the cells mainly via organic cationic transporters (OCTs) and multidrug and toxin extrusion transporters (MATEs)”
From Benefits of Metformin in Attenuating the Hallmarks of Aging (2020) · cites this paper as Gong et al. 2012
Three distinct classes of organic cation-selective transporters can be utilized by metformin: OCT1, 2 and 3; PMAT; and MATE1 and 2.
“There are three distinct classes of organic cation-selective transporters that can be utilized by metformin: Organic Cation Transporter (OCT) 1, 2 and 3 (SLC22A1, A2, A3); Plasma membrane Monoamine Transporter (PMAT; SLC29A4); and Multidrug And Toxin Extrusion protein (MATE) 1 and 2 (SLC47A1, A2), to enter and leave cells (Figure 1) (157).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
