Disease relevance of Slc22a8

  • In summary, CGNs accumulate MPP+ in manner that is consistent with uptake via OCT3 and the presence of this protein in CGNs explains their sensitivity to MPP+ toxicity [1].
 

High impact information on Slc22a8

  • In this study, we investigated the involvement of rat organic anion transporter 1 (rOat1; Slc22a6) and rOat3 (Slc22a8) in the uptake of PCG and p-aminohippurate (PAH) by the CP [2].
  • Corticosterone and 17beta-estradiol, known inhibitors of organic cation transporter 3 (OCT3), did not cause any significant inhibition [3].
  • RT-PCR demonstrated that astrocytes expressed low levels of OCT1, OCT2 and OCT3 mRNA, but the functional characteristics of choline uptake are very different from the known properties of these OCTs [3].
  • Organic anion transporter 3 (Slc22a8) is a dicarboxylate exchanger indirectly coupled to the Na+ gradient [4].
  • CGNs in primary culture express OCT3 but do not express mRNA for OCT1, OCT2 or the dopamine transporter [1].
 

Anatomical context of Slc22a8

  • The role of rat organic anion transporter 3 (rOat3; Slc22a8) in the efflux transport at the blood-brain barrier (BBB) was characterized [5].
  • The purpose of the present study is to examine whether organic anion transporter 3 (Oat3; Slc22a8) is solely responsible for the uptake of 2,4-D by the isolated rat choroid plexus (CP) [6].
  • Cerebellar astrocytes are negative for OCT3 protein by immunocytochemistry [1].
  • OCT3 was moderately expressed in kidney and was highest in blood vessel, skin, and thymus [7].
  • The Oct3-like band was detected only in epithelial cell extracts, the other two bands were also found in fibre cell extracts, whereby the intensity of the Oct2-like band decreased relative to that of the Oct7-like band during differentiation [8].
