Figure 5. Downstream effectors of canonical Wnt/β-catenin signaling in PC.

A, Random forest analysis intersecting genes most correlated with Wnt/β-catenin pathway activation in TCGA dataset and in VCaP cells with APC knockdown and RNF43i/WNT3a stimulation. B, qRT-PCR for downstream effectors of Wnt/β-catenin signaling in VCaP and RV1 cells with RNF43i/WNT3a stimulation (40 or 100 ng/ml) or APC knockdown. C, Immunoblotting of Wnt/β-catenin targets in VCaP (left panel) and RV1 (right panel) after RNF43i/WNT3a stimulation or APC knockdown (representative of at least 3 replicates).
