Additional file 1: of Planar cell polarity gene expression correlates with tumor cell viability and prognostic outcome in neuroblastoma

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).
