Mutidrug resistance-associated protein gene MRP/MRP1, and its family genes, including MRP2/cMOAT, have been isolated and characterized. These ATP-binding cassette (ABC) super-family transporter genes are differentially expressed in various normal tissues and multidrug-resistant cell lines. Transfection of MRP/MRP1 and MRP2/cMOAT cDNA confers drug resistance on different spectra of anticancer agents from that of MDR1 coding P-glycoprotein. Although it remains unclear how MRP/MRP1 and related family genes are specifically involved in drug resistance in clinical cancers, current knowledge of the MRP subfamily suggests the importance of this class of transporters as a molecular target for drug sensitivity to anticancer agents.
