[The effect of finoptin on doxorubicin accumulation in leukemia P-388 cells with induced resistance to the combination of finoptin and doxorubicin]

Abstract

Using hybrid mice BDF1 doxorubicin (Dx) accumulation has been determined in leukemia P388 cells (P388/0), P388 cells with induced resistance to Dx (P388/Dx) and P388 cells with induced resistance to the finoptin (Fp) + Dx combination (P388/Fp + Dx). It has been shown that Fp doesn't affect Dx accumulation in or elimination from leukemia cells P388/0 or P388/Fp + Dx. The resistance of P388/Fp + Dx cells to the Fp + Dx combination develops during 6 passages. It can be concluded that Fp application doesn't abolish the problem of tumor cells' resistance to cytostatics.
