Özet

We aimed to investigate whether resveratrol (RSV) could sensitize human triple-negative breast cancer (TNBC) cells to FL118-induced cell death, epithelial to mesenchymal transition (EMT), invasion, and migration. The effects of sequential administration of RSV and FL118 on MDA-MB-436 and MDA-MB-468 cells were evaluated in terms of cell viability, cytotoxicity, apoptosis, cell cycle distribution, active caspase-3/7 levels, migration and invasion. Furthermore, mRNA and protein levels of EMT associated genes and proteins were also evaluated. Sequential administration of RSV and FL118 inhibited the cell viability in both TNBC cell lines. Meanwhile sequential administration of RSV and FL118 also dramatically reduced the migratory and invasive capabilities, it also reversed the EMT process in both TNBC cells. Moreover, sequential administration of RSV and FL118 led to a significant increase of apoptotic cells, as well as active Caspase-3/7 levels. Sequential administration of RSV and FL118 caused TNBC cells accumulating in the G1 phase, and markedly suppressed the mRNA and protein levels of N-cadherin, beta-catenin, Vimentin, Snail, and Slug, and also significantly downregulated mRNA levels of Fibronectin, Twist1, Twist2, Zeb1, and Zeb2 genes, while enhanced the mRNA and protein levels of E-cadherin genes. RSV sensitized TNBC cells to FL118 via facilitating apoptosis, migration, invasion, and EMT and enhancing intracellular entrapment of FL118. Thus, our results suggest that since RSV enhanced the in vitro anticancer activity of FL118 in BC, it may be a potential therapeutic agent in advanced BC.
