High impact information on OAT-2

  • Degenerate primers were designed based on the sequences conserved among OAT1, OAT2, and organic cation transporter 1 (OCT1), and reverse transcription-polymerase chain reaction was performed using rat brain poly(A)+ RNA [1].
  • Rat organic anion transporter 1 (Oat1), Oat2, and Oat3, members of the organic anion transporter family, transport some organic anions across cellular membranes [2].
  • RT-PCR analysis indicated gene expression of Oat2, Oatplal, Oatpla4, Oatplb2, Rfc-1/MTX-1, FOLR, Mrp1-6, mdr1, and Lrp [3].
  • OctN1 and N2, Oatp2, Oat2 and 3, and Cnt1 and 2 mRNAs expressions were detectable in choroid plexus, but the levels were lower compared with that in liver, kidney, or ileum [4].
  • There were no sex differences in the expression of rOAT1 mRNA. rOAT2 mRNA was abundant in the liver and weakly expressed in the kidney of male rats; however, the OAT2 gene was strongly expressed in both organs of females [5].

Anatomical context of OAT-2

  • Role of nitric oxide (NO) on the expression of organic anion transporter 2 (OAT2) located in sinusoidal domain of hepatocytes has been investigated [6].
