Overexpression of the multidrug resistance-associated protein (MRP) gene in vincristine but not doxorubicin-selected multidrug-resistant murine erythroleukemia cells.
Multidrug-resistant sublines of the murine erythroleukemia cell line PC4 were sequentially selected in increasing vincristine concentrations (5-160 ng/ml). The low- and intermediate-level resistant cell lines, selected in < or = 40 ng/ml of vincristine, demonstrated resistance to Vinca alkaloids and to an epipodophyllotoxin but little or none to an anthracycline. The expression of murine mdr ge...
متن کاملCharacterization of transport protein expression in multidrug resistance-associated protein (Mrp) 2-deficient rats.
Multidrug resistance-associated protein (Mrp) 2-deficient transport-deficient (TR(-)) rats, together with their transport-competent Wistar counterparts (wild type), have been used to examine the contribution of Mrp2 to drug disposition. However, little is known about potential variation in expression of other transport proteins between TR(-) and wild-type rats or whether these differences are t...
متن کاملTransport of methotrexate (MTX) and folates by multidrug resistance protein (MRP) 3 and MRP1: effect of polyglutamylation on MTX transport.
We have recently determined that human multidrug resistance protein (MRP) 3, which confers resistance to certain natural product agents and methotrexate (MTX), is competent in the MgATP-energized transport of MTX and the monoanionic bile constituent glycocholate as well as several glutathione and glucuronate conjugates. Of these capabilities, the facility of MRP3 in conferring resistance to and...

متن کاملModulation 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...
