Figure 7. YAP1 is essential for FGF8-mediated tumor growth and metastasis.

FGF8-treated RKO cells were transfected with siYAP1 or siNC. (A-B) Proliferative activity was measured by a colony formation assay (A) and BrdU labeling (B). (C) Cell migration and invasion was examined by transwell assay and matrigel invasion assays. (D) Representative phase-contrast images of RKO cell morphology. (E) Expression of Snail, E-cadherin and Vimentin was examined by immunoblot. All data were from at least three independent experiments. *, P<0.05; **, P<0.01; ***, P<0.001.
