Figure Lengend Snippet: Cell migration and invasion assays following ectopic expression of miR-451a in LUSQ cells. ( A ) Cell migration was measured by wound healing assays (* p < 0.001). ( B ) Cell invasion was determined by Matrigel invasion assays (* p < 0.001). Phase-contrast micrographs of LUSQ cells in migration and micrographs of LUSQ cells in invasion assays are shown.

Figure Lengend Snippet: Compound 4a markedly diminished the invasiveness of cervical cancer cells (HeLa). The anti-invasive potential of the test compound is illustrated by representative images ( B ), and is quantified by the percentage of invading cells in the Boyden chamber containing different concentrations of 4a , using an EMEM medium supplemented with 10% FBS as a chemoattractant ( A ). Results are presented as mean values ± SEM of the data from three separate measurements with duplicates. ** and *** indicate p < 0.01 and p < 0.001, respectively, compared to untreated control samples.
