A cryptic multidrug resistance (MDR) system in Stenotrophomonas maltophilia, the expression of which is selectable by tetracycline, is described. Tetracycline resistance was the consequence of active efflux of the antibiotic, and it was associated with resistance to quinolones and chloramphenicol, but not to aminoglycosides or beta-lactam antibiotics. MDR is linked to the expression of an outer...
The PmrA multidrug transporter protein gene was inactivated in Streptococcus pneumoniae strains CP1000 (wild-type) and EBR (mutant with enhanced active multidrug efflux). While the resistance to fluoroquinolones and ethidium bromide shown by EBR was reduced to the wild-type level, neither the susceptibility to reserpine in the presence of ethidium bromide and selected fluoroquinolones, nor the ...
The elucidation of the means by which tumor cells develop resistance to the toxic effects of potent chemotherapeutic agents has revealed a great deal about mechanisms of drug uptake, metabolism, and extrusion, as well as providing basic insights into cellular processes such as regulation of gene expression and gene amplification. One perplexing problem facing the cell biologist and oncologist h...
Elevated expression of the drug efflux transporter ABCG2 seems to correlate with multidrug resistance of cancer cells. Specific COX-2 inhibitor celecoxib has been shown to enhance the sensitivity of cancer cells to anticancer drugs. To clarify whether ABCG2 inhibition is involved in the sensitizing effect of celecoxib, we investigated whether the expression of ABCG2 in breast cancer cell lines ...
Metabolic energy preferentially produced by glycolysis was an advantageous metabolic phenotype of cancer cells. It is also an essential contributor to the progression of multidrug resistance in cancer cells. By developing human breast cancer MCF-7 cells resistant to doxorubicin (DOX) (MCF-7/MDR cells), the effects and mechanisms of 2-deoxy-D-glucose (2DG), a glucose analogue, on reversing multi...
Acinetobacter baumannii, a strictly aerobic, non-fermentative, Gram-negative coccobacillary rod-shaped bacterium, is an opportunistic pathogen in humans. We recently isolated a multidrug-resistant A. baumannii strain KBN10P02143 from the pus sample drawn from a surgical patient in South Korea. We report the complete genome of this strain, which consists of 4,139,396 bp (G + C content, 39.08%) w...
