title: [Multidrug resistance (MDR)].
abstract: Multiple drug resistance (MDR) is a major problem of current chemotherapy. Establishment of multiple drug resistant cell lines in culture and isolation of P-glycoprotein-coding MDR genes have promoted understanding of the molecular mechanisms underlying drug resistance in tumors. Another gene, MRP, has been recently isolated from a multiple drug resistant cell line which did not express P-glycoprotein. Both genes have DNA sequence homology for each other and have been identified as members of ATP binding cassette (ABC) transporter superfamily. This review refers to recent progress in MDR and MRP study, and focuses on involvement of these two drug-resistance-related genes in acquiring drug resistance and their physiological functions.
