Effects of miR-7-5p, TFF3 and LY294002 on the migration of LS174T cells. (A) The crystal violet staining results of LS174T cell migration through the Transwell chamber (magnification, ×200): (a) LS174T cells transfected with miR-7-5p mimic NC; (b) LS174T cells transfected with miR-7-5p mimics; (c) LS174T cells transfected with miR-7-5p mimics and TFF3 plasmid; (d) LS174T cells transfected with miR-7-5p mimic NC and LY294002; (e) LS174T cells transfected with miR-7-5p mimics and LY294002; (f) LS174T cells transfected with miR-7-5p mimics, TFF3 plasmid and LY294002. (B) Histogram of the number of LS174T cells migrating through the Transwell chamber. The assays were performed in triplicate. All values are presented as the means ± standard deviation of three replicates. miR. *P<0.05. miR, microRNA; TFF3, trefoil factor 3; NC, negative control.
