Knockdown of Prickle1 or Vangl2 alters neuroblastoma cell viability. Transfection of neuroblastoma cells using alternative siRNA’s against Prickle1 and Vangl2 resulted in a significant increase of cell viability compared to control cells transfected with scrambled siRNA sequence (48 h) in SK-N-AS. Also in SK-N-BE (2) an increase were recorded after siRNA against Prickle1 (one-way ANOVA with Bonferroni post-test, SK-N-AS: P < 0.0001 control vs Prickle1 P < 0.0001, control vs Vangl2 P < 0.0001; SK-N-BE (2): P = 0.026: control vs Prickle1 P = 0.017). Figure S2: Correlation between expression of Prickle1 and Vangl2 and survival in neuroblastoma. a) Kaplan-Meier survival estimates of high vs low expression of Prickle1 and Vangl2 in neuroblastoma expression cohorts analyzed using the microarray analysis and visualization platform (http://r2.amc.nl). b Box-plot of Prickle1 and Vangl2 expression correlated to neuroblastoma disease stage (PPTX 486 kb)
