Determination of the overlap of signature genes after RNAi-mediated silencing of POMP, NUPL1, KLF5, DIS3, and LNX2 with genes known to be either downregulated (A) or upregulated (B) by colorectal cancer-associated transcription factors TCF7L2, β-catenin, SMAD4, VDR, MYC, and κ (Color code at the bottom of the Figure). The red-dashed line indicates a significance threshold of P<0.01.
