Figure 1A549 cells expressing control shRNA, WDR63 shRNA#1, WDR63 shRNA#2, PCDH control, or PCDH-Flag-WDR63 were subjected to wound-healing (A) assays. The shown images are representative of three independent experiments. Data shown are mean ± SD (n=3). **, P ˂ 0.01; ***, P ˂ 0.001; One-way ANOVA. Scale bar in (A): 200 μm. A549 cells expressing control shRNA, WDR63 shRNA#1, WDR63 shRNA#2, PCDH control, or PCDH-Flag-WDR63 were subjected to transwell migration (B) assays. The shown images are representative of three independent experiments. Data shown are mean ± SD (n=3). **, P ˂ 0.01; ***, P ˂ 0.001; One-way ANOVA. Scale bar in (B): 100 μm. (C) Effect of WDR63 knockdown on the migration of A549 cells was analyzed by single cell tracking with time-lapse microscopy at 10 min intervals for 4 h. Scale bar: 200 μm. Cell migration speed, persistence, and mean squared displacement (MSD) were also analyzed using an Excel macro described by Gorelik and Gautreau. Data shown are mean ± SD. n = 3 independent experiments. *, P ˂ 0.05; **, P ˂ 0.01; ***, P ˂ 0.001; One-way ANOVA. (D) A549 cells expressing control shRNA, WDR63 shRNA#1, WDR63 shRNA#2, PCDH control, or PCDH-Flag-WDR63 were subjected to transwell invasion assay. The shown images are representative of three independent experiments. Data shown are mean ± SD (n=3). *, P ˂ 0.05; **, P ˂ 0.01; ***, P ˂ 0.001; One-way ANOVA. Scale bar: 100 μm. A549 cells expressing control shRNA, WDR63 shRNA#1, or WDR63 shRNA#1 plus shRNA-resistant Flag-WDR63 were subjected to transwell migration (E) assays. The shown images are representative of three independent experiments. Cell migration speed, persistence, and mean squared displacement (MSD) were also analyzed using an Excel macro described by Gorelik and Gautreau. Data shown are mean ± SD. n = 3 independent experiments. *, P ˂ 0.05; **, P ˂ 0.01; ***, P ˂ 0.001; One-way ANOVA. Scale bar : 100 μm. A549 cells expressing control shRNA, WDR63 shRNA#1, or WDR63 shRNA#1 plus shRNA-resistant Flag-WDR63 were subjected to single cell tracking (F) assays. The shown images are representative of three independent experiments. Cell migration speed, persistence, and mean squared displacement (MSD) were also analyzed using an Excel macro described by Gorelik and Gautreau. Data shown are mean ± SD. n = 3 independent experiments. *, P ˂ 0.05; **, P ˂ 0.01; ***, P ˂ 0.001; One-way ANOVA. Scale bar 200 μm. A549 cells expressing control shRNA, WDR63 shRNA#1, or WDR63 shRNA#1 plus shRNA-resistant Flag-WDR63 were subjected to transwell invasion (G) assays. The shown images are representative of three independent experiments. Cell migration speed, persistence, and mean squared displacement (MSD) were also analyzed using an Excel macro described by Gorelik and Gautreau. Data shown are mean ± SD. n = 3 independent experiments. *, P ˂ 0.05; **, P ˂ 0.01; ***, P ˂ 0.001; One-way ANOVA. Scale bar : 100 μm. (H) A549 cells expressing control shRNA, WDR63 shRNA#1, or WDR63 shRNA#2 (each also expressing luciferase) were injected via tail vein into nude mice (n=6 for each group). Three weeks after injection, tumor formation was monitored by bioluminescence imaging. Data shown are mean ± SD; *, P ˂ 0.05; One-way ANOVA.
