Cisplatin induces renal expression of P-glycoprotein and canalicular multispecific organic anion transporter.
The expression of two members of the ATP-binding cassette family of transport proteins, P-glycoprotein (P-gp) and the canalicular multispecific organic anion transporter (cMOAT or Mrp2), was evaluated in renal brush-border membranes (BBM) and various rat tissues after cisplatin treatment. One administration of cisplatin (5 mg/kg) increased P-gp expression by >200-300% in renal BBM and in crude ...
متن کاملRat multispecific organic anion transporter 1 (rOAT1) transports zidovudine, acyclovir, and other antiviral nucleoside analogs.
Organic anion transporter 1 (OAT1) is a p-aminohippurate/dicarboxylate exchanger that plays a primary role in the tubular secretion of endogenous and exogenous organic anions. OAT1 is located in the basolateral membrane of the proximal tubular cells and mediates the uptake of various organic anions from the peritubular fluid. In this study, we investigated the transport of antiviral nucleoside ...
متن کاملCloning and functional characterization of a new multispecific organic anion transporter, OAT-K2, in rat kidney.
We have isolated a cDNA coding a new organic anion transporter, OAT-K2, expressed specifically in rat kidney. The OAT-K2 cDNA had an open reading frame encoding a 498-amino acid protein (calculated molecular mass of 55 kDa) that shows 91% identity with the rat kidney-specific organic anion transporter, OAT-K1. Reverse transcription-coupled polymerase chain reaction analyses revealed that the OA...
متن کاملTransport of ochratoxin A by renal multispecific organic anion transporter 1.
In the present study, we investigated the transport of ochratoxin A (OTA) by kidney-specific organic anion transporter 1 (OAT1). When expressed in Xenopus laevis oocytes, OAT1 mediated sodium-independent uptake of OTA (Km = 2.1 microM). Piroxicam, which has been shown to prevent the nephrotoxicity of OTA, inhibited OAT1-mediated uptake of OTA. By contrast, another protective compound, aspartame...
متن کاملIsolation, characterization and differential gene expression of multispecific organic anion transporter 2 in mice.
We isolated cDNA encoding a multispecific organic anion transporter 2 (OAT2) from the mouse kidney cDNA library. Isolated mouse OAT2 (mOAT2) consisted of 1623 base pairs that encoded a 540-amino acid residue protein with 12 putative membrane-spanning domains, and the amino acid sequence was 87% identical to that of rat OAT2 (rOAT2). The gene coding for mOAT2, Slc22a7, is found on chromosome 17C...
