The side population cells characterized by the ability to transport Hoechst 33342 out of cells have been identified as cancer stem-like cells. ABCG2 is found to confer the side population (SP) phenotype, multidrug resistance (MDR) and tumor recurrence. In this study, we found secalonic acid D (SAD), a metabolite of marine-derived mangrove endophytic fungus,(More)
Incomplete chemotherapeutic eradication of leukemic CD34⁺CD38⁻ stem cells is likely to result in disease relapse. The purpose of this study was to evaluate the effect of nilotinib on eradicating leukemia stem cells and enhancing the efficacy of chemotherapeutic agents. Our results showed that ABCB1 and ABCG2 were preferentially expressed in leukemic(More)
Lapatinib, a tyrosine kinase inhibitor, is used in the treatment of advanced or metastatic breast cancer overexpressing human epidermal receptor 2 (HER2). Lapatinib can modulate the function of ATP-binding cassette (ABC) transporters (ABCB1 and ABCG2), which are the major mechanism responsible for multidrug resistance (MDR) in cancer. In this study, we(More)
