The multidrug resistance protein (MRP) is an ATP-dependent transport protein for organic anions, as well as neutral or positively charged anticancer agents. In this study we report that dinitrophenyl-S-glutathione increases ATPase activity in plasma membrane vesicles prepared from the MRP-overexpressing cell line GLC4/ADR. This ATPase stimulation parallels the uptake of DNP-SG in these vesicles. We also show that the (iso)flavonoids genistein, kaempferol and flavopiridol stimulate the ATPase activity of GLC4/ADR membranes, whereas genistin has no effect. The present data are consistent with the hypothesis that certain (iso)flavonoids affect MRP-mediated transport of anticancer drugs by a direct interaction with MRP.

D009363 Neoplasm Proteins Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm. Proteins, Neoplasm
