Fig. 5. The inhibition of motility of breast cancer cells by miR-488 can be attenuated by its target, FSCN1.
A The wound width was decreased under the treatment of miR-488 inhibitor, consistent with the level of FSCN1, and the wound healing abilities was resuppressed when knockdown the expression of FSCN1 in MCF-7-miR-488-inhibitor cells. B The migration and invasion abilities were consistent with the wound healing abilities, reflecting the motility of MCF-7 cells, which was suppressed in siFSCN1+miR-488 inhibitor-treated cell compared with miR-488 suppressing function. C The wound healing rate was decreased by miR-488 mimic, and the reverse effect was found in the re-overexpression of FSCN1 in MDA-MB-231 cells. D The migration and invasion abilities were consistent with the wound healing assays, predicting the motility of MDA-MB-231, which was promoted by re-overexpression of FSCN1 compared with the NC group.*p < 0.05, **p < 0.01, and ***p < 0.001.
