Significant inferred TF activity differences between CTNNB1 mutant and WT patients (satisfying FDR-corrected P<0.01, t-test) associated CTNNB1 mutant status with altered activity of TFs involved in WNT signalling, epithelial–mesenchymal transition and cancer stem cell transition including TCF4 (transcriptional factor 4), NFATC4, JUN, TP53, MAX, MYC, STAT3 and KLF12 (Fig. 3f). This evidence concerns the gene TCF4 and cancer.
