UNLABELLED Multidrug efflux systems are a major cause of resistance to antimicrobials in bacteria, including those pathogenic to humans, animals, and plants. These proteins are ubiquitous in these pathogens, and five families of bacterial multidrug efflux systems have been identified to date. By using transcriptomic and biochemical analyses, we recently identified the novel AceI (Acinetobacter ...
Tumor cells may display a multidrug resistant phenotype by overexpression of ATP-binding cassette transporters such as multidrug resistance (MDRI) P-glycoprotein, multidrug resistance protein 1 (MRP1), and breast cancer resistance protein (BCRP). The presence of BCRP has thus far been reported solely using mRNA data. In this study, we describe a BCRP-specific monoclonal antibody, BXP-34, obtain...
We have established four cell lines derived from the human KB carcinoma cell line which express high-level multiple drug resistance. One of these lines was selected for resistance to colchicine, one was selected for resistance to colchicine in the presence of the tumor promoter, mezerein, one for resistance to vinblastine, and one for resistance to adriamycin. All of these cell lines are cross-...
The calcium channel blocker verapamil has been shown to reverse multidrug resistance (T. Tsuruo et al.. Cancer Res. 41:1967-1972,1981), but the mechanism of action of this agent has not been fully elucidated. A radioactive photoactive analogue of verapamil, V-|Acncor/-.',5-'H(±)-5-|(3,4-dimethoxyphenetyl)methylamino|-2-(3,4-dimethoxyphenyl)2-isopropyl-/V-/>-azidobenzoylpentylamine, was used to...
The prognostic significance of multidrug resistance (MDR) gene expression is controversial. We investigated whether multidrug resistance gene 1 (MDR1), multidrug resistance-related protein (MRP) and lung resistance protein (LRP) mRNA expression are associated with outcomes in acute leukemia patients. At diagnosis we examined MDR1, MRP and LRP mRNA expression in bone marrow samples from 71 acute...
MdfA is an Escherichia coli multidrug-resistance transporter. Cells expressing MdfA from a multicopy plasmid exhibit multidrug resistance against a diverse group of toxic compounds. In this article, we show that, in addition to its role in multidrug resistance, MdfA confers extreme alkaline pH resistance and allows the growth of transformed cells under conditions that are close to those used no...
