M238P cells were transfected with two different sequences of siRNAs vs FSCN1 or with a control siRNA (72 h, 100 nM). (D) Migration assay performed in Boyden chambers. Representative images showing migration of M238P cells treated with the indicated siRNAs. The bar graph represents the quantitative determination of data obtained of mean ± SD from 5 independent fields representative of 3 independent experiments, using ImageJ software. Paired Student t-test was used for statistical analysis. *P≤0.05, ***P≤0.001
