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.

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.
