Can P glycoprotein mediate resistance to nilotinib in human leukemia cells?

Original language description

The effect of P-glycoprotein (P-gp, ABCB1, MDR1) expression on cell resistance to nilotinib was studied in human leukaemia cells. We used K562/Dox cells overexpressing P-gp and their variants (subclones) with a gradually decreased P-gp expression. Thesesubclones were established by stable transfection of K562/Dox cells with a plasmid vector expressing shRNA targeting the ABCB1 gene. Functional analysis of P-gp using a specific fluorescent probe indicated gradually decreased dye efflux which was proportional to the P-gp expression. We observed that K562/Dox cells overexpressing P gp contained a significantly reduced intracellular level of nilotinib when compared to their counter partner K562 cells, which do not express P-gp. This effect was accompaniedby a decreased sensitivity of the K562/Dox cells to nilotinib. Importantly, cells with downregulated expression of P gp gradually lost their ability to decrease the intracellular level of nilotinib although they still significantly decre
