Figure 5. MIEN1 depletion inhibits the cell motility and associated signaling in breast cancer cells.
(A) MDA-MB-231 cells transfected with control or MIEN1 siRNA were collected at 72 h post-transfection. The cells were lysed and subjected to Western blot analysis with the indicated antibodies. (B) MDA-MB-231 cells were treated with control or MIEN1 siRNA for 72 h and subjected to wound healing upon sub-confluency. The wounded areas were photographed directly after the wounding and at the indicated time points. Representative images of the wound closure are shown. (C) Quantification of the wound-healing assays in MDA-MB-231 is depicted. (*p < 0.05) (D) Representative images of agarose bead assay in MDA-MB-231 cells treated with control or MIEN1 siRNAs. (E) Quantification of number of cells migrated out from at least 10 independent fields. (***p < 0.001 vs control).
