Chemo-resistance to anti-cancer drugs is a major obstacle in efforts to develop a successful treatment of cancer.Resveratrol(RSV)facilitates the cellular uptake of doxorubicin through an induced down-regulation of multidrug resistance -associated protein-1(MRP1)expression.We studied whether RSV enhances the cytotoxic effect of vinblastine,vincristine,irinotecan,and etoposide in MRP1-expressing Burkitt's lymphoma Raji cells.Treatment with RSV caused decrease of cell viability in a time-and dose-dependent manner,and down-regulation of MRP1 expression in Raji cells.The cytotoxic effects of vinblastine,vincristine,and etoposide increased in RSV-pretreated Raji cells,but the effect of irinotecan did not change in the cells.These results indicate that RSV enhances the cellular uptake of vinblastine,and etoposide in Raji cell.
