Fisetin reverses EMT in TNBC cells in vitro. TNBC cell lines MDA-MB-231 and BT549 were treated with vehicle or fisetin for 24 h. (A) The morphology of the cells treated with vehicle or 30 μM fisetin was observed by phase-contrast microscopy. (B) E-cadherin and (C) Vimentin and F-actin expression were evaluated by immunofluorescence in TNBC cells treated by vehicle or 30 μM fisetin. The cells pretreated with vehicle or various concentrations of fisetin (10, 30, and 100 μM, respectively) were subjected to western blot for the indicated proteins (D) and qRT-PCR for the indicated mRNA (E). The results are shown as the mean ± SD of three experiments, ∗P < 0.05, ∗∗P < 0.01 compared with control.
