The Great Multidrug-Resistance Paradox

Multidrug Recognition 151 The Ostensible Paradox of Multidrug Recognition

The ability of multidrug-efflux transporters to recognize scores of dissimilar organic compounds has always been considered paradoxical because of its apparent contradiction to some of the basic dogmas of biochemistry. In order to understand, at least in principle, how a protein can recognize multiple compounds, we analysed the transcriptional regulator of the Bacillus subtilis multidrug transp...

Multidrug resistance associated proteins in multidrug resistance

Multidrug resistance proteins (MRPs) are members of the C family of a group of proteins named ATP-binding cassette (ABC) transporters. These ABC transporters together form the largest branch of proteins within the human body. The MRP family comprises of 13 members, of which MRP1 to MRP9 are the major transporters indicated to cause multidrug resistance in tumor cells by extruding anticancer dru...

Multidrug Resistance in Infants and Children

Bacterial infections may cause disease and death. Infants and children are often subject to bacterial infections. Antimicrobials kill bacteria protecting the infected patients andreducing the risk of morbidity and mortality caused by bacteria. The antibiotics may lose their antibacterial activity when they become resistant to a bacteria. The resistance to different antibiotics in a bacteria is ...

The multidrug resistance phenotype confers immunological resistance

Multidrug resistance (MDR), which is due, in part, to the overexpression of P-glycoprotein, confers resistance to a variety of natural product chemotherapeutic agents such as daunorubicin, vincristine, and colchicine. RV+ cells are a P-glycoprotein overexpressing variant of the HL60 myeloid leukemia cell line. In addition to classic MDR, RV+ cells displayed relative resistance to complement-med...
