Fig.Figure 5a Differential gene expression analysis shows a set of 196 genes being regulated by CHIR in d4TCF cells; several of these changes only appear when TCF/LEF proteins are not present (dark green set). Of the 134 genes that are not regulated by CHIR in dBcat cells (putative β-catenin-dependent genes), 107 require the removal of TCF/LEF factors, in that their regulation only occurs in d4TCF cells. The other 27/134 β-catenin-dependent transcriptional changes match the TCF/LEF-independent target genes previously described in Figure 3a. Their regulation occurs both in the presence and in the absence of TCF/LEF factors. 90/107 of the putative β-catenin-dependent genes, stop being regulated by CHIR in pentaKO cells (β-catenin-GHOST, blue box) b RT-qPCR validation of the β-catenin-GHOST response. A selection of 7 genes (colour coded) that are activated upon CHIR treatment in d4TCF, or in wild-type (WT) in combination with ICAT overexpression, but not in pentaKO cells - indicating that their regulation is dependent on β-catenin but can only occur in the absence of TCF/LEF-β-catenin interaction. The genotype and the treatment for each condition is indicated in the x-axis. Error bars show that standard deviation obtained from 3 independent experiments c FOXO4 but not FOXO3 overexpression upregulates the β-catenin-GHOST target GADD45 both in CHIR-treated WT (black bars) or d4TCF (grey bars) cells. Samples were compared using Student"s t-test. Asterisks (*) indicate a p-value< d FOXO4 overexpression induced GADD45 transcription in WT (black bars) but not in dBcat (grey bars) cells. Samples were compared using Student"s t-test. Asterisks (*) indicate a p-value< e Endogenous FOXO4, when immunoprecipitated (IP) pulls down β-catenin. Overexpressed FOXO4 increases the amount of β-catenin detected in the immunoprecipitated, indicating physical association f GADD45 is upregulated by CHIR in d4TCF cell; this positive transcriptional regulation is blocked by FOXO4-specific siRNA but not control scrambled siRNA.
