Modulation by acrolein and chloroacetaldehyde of multidrug resistance mediated by the multidrug resistance-associated protein (MRP).
Acrolein (AC) and chloroacetaldehyde (CHA) are metabolites of the non-multidrug resistance cytotoxic drugs cyclophosphamide and ifosfamide. It has previously been reported that both metabolites can induce extensive depletion of glutathione (GSH) in vitro and in vivo and that this depletion occurs at drug concentrations in the micromolar range. A link between the function of the multidrug resist...
متن کاملRapid, nongenomic stimulation of multidrug resistance protein 2 (Mrp2) activity by glucocorticoids in renal proximal tubule.
In renal proximal tubule, multidrug resistance protein 2 (Mrp2) actively transports many organic anions into urine, including drugs and metabolic wastes. Upon exposure to nephrotoxicants or during endotoxemia, both Mrp2 activity and expression are up-regulated. This may result from induced de novo synthesis of Mrp2 or post-transcriptional events involving specific signaling pathways. Here, we i...
متن کاملEnzymatic synthesis of nucleoside diphosphates and triphosphates.
It has been recognized from recent studies that nucleoside triphosphates, other than ATP,’ function in biologic systems as phosphorylating agents (1) and in coenzyme synthesis (2) in a manner analogous to that of ATP. The discovery of the natural occurrence of a variety of purine and pyrimidine nucleoside diand triphosphates (3-5) and the likelihood that new biologic functions for these nucleot...
متن کاملRegulation of expression and activity of rat intestinal multidrug resistance-associated protein 2 by cholestatic estrogens.
The effect of the cholestatic estrogens ethynylestradiol (EE) and estradiol 17beta-D-glucuronide (E2-17G) on expression and activity of intestinal multidrug resistant-associated protein 2 (Mrp2, Abcc2) was studied in rats. Expression and localization of Mrp2 were evaluated by Western blotting, real-time polymerase chain reaction, and confocal immunofluorescence microscopy. Mrp2 transport activi...
متن کاملMultidrug 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...
