Multidrug resistance proteins (MRPs) are members of the C family of a group of proteins named ATP-binding cassette (ABC) transporters. These ABC transporters together form the largest branch of proteins within the human body. The MRP family comprises of 13 members, of which MRP1 to MRP9 are the major transporters indicated to cause multidrug resistance in(More)
ABCC10, also known as multidrug-resistant protein 7 (MRP7), is the tenth member of the C subfamily of the ATP-binding cassette (ABC) superfamily. ABCC10 mediates multidrug resistance (MDR) in cancer cells by preventing the intracellular accumulation of certain antitumor drugs. The ABCC10 transporter is a 171-kDa protein that is localized on the basolateral(More)
It is well established that ATP-binding cassette (ABC) transporter-mediated multidrug resistance (MDR) is one of the major mechanisms that causes resistance to antineoplastic drugs in cancer cells. ABC transporters can significantly decrease the intracellular concentration of antineoplastic drugs by increasing their efflux, thereby lowering their cytotoxic(More)
Multidrug resistance (MDR) is a phenomenon where cancer cells become simultaneously resistant to anticancer drugs with different structures and mechanisms of action. MDR has been shown to be associated with overexpression of ATP-binding cassette (ABC) transporters. Here, we report that telatinib, a small molecule tyrosine kinase inhibitor, enhances the(More)
Paclitaxel displays clinical activity against a wide variety of solid tumors. However, resistance to paclitaxel significantly attenuates the response to chemotherapy. The ABC transporter subfamily C member 10 (ABCC10), also known as multidrug resistance protein 7 (MRP7) efflux transporter, is a major mediator of paclitaxel resistance. In this study, we show(More)
ATP-binding cassette (ABC) transporters are present in the majority of human tumors and are involved in multidrug resistance (MDR). Therefore, compounds that inhibit the function of ABC transporters may improve the efficacy of anticancer agents. Previous research has shown that zafirlukast is a reversal drug for multidrug resistance protein (MRP) 1-mediated(More)
AIM This study aimed to investigate the mechanism of reversal of multidrug resistance mediated by ABC transporters with tivozanib (AV-951 and KRN-951). Tivozanib is a potent inhibitor of VEGF-1, -2 and -3 receptors. MATERIALS & METHODS ABCB1- and ABCG2-overexpressing cell lines were treated with respective substrate antineoplastic agents in the presence(More)
Cancer cells often become resistant to chemotherapy through a phenomenon known as multidrug resistance (MDR). Several factors are responsible for the development of MDR, preeminent among them being the accelerated drug efflux mediated by overexpression of ATP binding cassette (ABC) transporters. Some small molecule tyrosine kinase inhibitors (TKIs) were(More)
ATP-binding cassette (ABC) transmembrane proteins evidently decrease the intracellular accumulation of substrate chemotherapeutic drugs by extruding them against a concentration gradient, thereby inducing drug resistance. Here we reported the effect of WHI-P154, an irreversible inhibitor of Janus kinase 3 and epidermal growth factor receptor tyrosine(More)
Multidrug resistance protein 7 (MRP7, ABCC10) is a recently identified member of the ATP-binding cassette (ABC) transporter family, which adequately confers resistance to a diverse group of antineoplastic agents, including taxanes, vinca alkaloids and nucleoside analogs among others. Clinical studies indicate an increased MRP7 expression in non-small cell(More)
