(A) Representative images from immunofluorescence experiments showing the cellular NICD1 distribution. NICD1 is stained in green and nuclei in blue, with DAPI in merged images (lower panels). Scale bar: 50 μm.
(B) NICD1 nuclear score (for calculation details, see Experimental Procedures section). One dot represents a measurement of one cell. Bars show means ± SEM of three independent experiments. Statistical analyses were performed by using one-way ANOVA.
(C-D) MDA-MB-231 were transfected with the indicated siRNAs (scramble, siBRD4: 50 nM; siJagged1: 20 nM) for 72h prior to conduct migration (C) and invasion (D) assays. Bars show means ± SEM of three independent experiments. Statistical analyses were performed by using one-way ANOVA.
(E-F) MDA-MB-231 were transfected with the indicated siRNAs (scramble, siBRD4: 50 nM; siJagged1: 20 nM) for 72h and plasmids for 24h prior to conduct migration (E) and invasion (F) assays. Bars show means ± SEM of three independent experiments. Statistical analyses were performed by using one-way ANOVA.
The following symbols were used to indicate significant differences: ns, p > 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001.
