Default Differentiation of the P-gp and MRP1 multidrug resistance systems by mobile lipid 1H-

Differentiation of the P-gp and MRP1 multidrug resistance systems by mobile lipid 1H-NMR spectroscopy and phosphatidylserine externalization.

Related Articles Differentiation of the P-gp and MRP1 multidrug resistance systems by mobile lipid 1H-NMR spectroscopy and phosphatidylserine externalization.

Anticancer Res. 2001 Nov-Dec;21(6A):3915-9

Authors: Mannechez A, Collet B, Payen L, Lecureur V, Fardel O, Le Moyec L, de Certaines JD, Leray G

We have previously demonstrated that proton NMR spectra of fatty acid chains in erythroleukemia K562 wild-type cells and their MDR1 counterparts show variations related to the phenotype over-expressing the P-glycoprotein (P-gp). Human lung cancer cells whose multidrug resistance (MDR) counterparts over-express the multidrug resistance-associated protein MRP1 have not yet been studied by NMR. Both P-gp and MRP1 belong to the same ATP-binding cassette transporter superfamily. A comparison of NMR spectra from both these multidrug-resistance phenotypes showed that the results previously obtained on the MDR1 family are not valid for MRP1. Furthermore, flow cytofluorimetry studies with external phosphatidylserine labelling showed that P-gp and MRP1 overexpressions have strong but differentiated effects on cell lipid pools.
