Pathways - manually collected, often from reviews:

  • OpenBEL Selventa BEL large corpus: CTNNB1 → CDX2 (decreases)
    Evidence: The homeodomain transcription factors Cdx1 and Cdx2 induce E-cadherin adhesion activity by reducing beta- and p120-catenin tyrosine phosphorylation. We specifically investigated beta- and p120-catenin for tyrosine phosphorylation and found that it was significantly diminished by Cdx1 or Cdx2 expression.

Guo et al., J Biol Chem 2004 (Colonic Neoplasms) : We report that Cdx1 or Cdx2 expression does inhibit beta-catenin/TCF transcriptional activity in colon cancer cells ... Finally, we show that colon cancer cells effectively reduce Cdx2 mediated inhibition of Wnt/beta-catenin/TCF transcriptional activity when compared with other model systems ... This suggests that colon cancer and possibly crypt epithelial cells can modulate the effects of Cdx2 on beta-catenin signaling and proliferation
Saegusa et al., Carcinogenesis 2007 (Endometrial Neoplasms) : A functional role of Cdx2 in beta-catenin signaling during transdifferentiation in endometrial carcinomas ... In cell lines, over-expression of active form beta-catenin resulted in a significant increase in endogenous Cdx2 expression at both mRNA and protein levels ... Furthermore, the Cdx2 promoter was activated by T-cell factor 4 (TCF4) -independent activated beta-catenin , as well as Cdx2 itself, through the region from -39 to +9 bp relative to transcription start site ... These data suggest that over-expression of Cdx2 mediated by nuclear beta-catenin and Cdx2 itself can cause an inhibition of Em Ca cell proliferation through up-regulation of p21 ( Waf1 ) expression, modulating beta-catenin/TCF4 mediated transcription
Guo et al., Carcinogenesis 2010 (Colonic Neoplasms) : The intestine-specific transcription factor Cdx2 inhibits beta-catenin/TCF transcriptional activity by disrupting the beta-catenin-TCF protein complex ... Specifically, inhibition of beta-catenin/TCF activity by Cdx2 does not require Cdx2 transcriptional activity ... We identify a subdomain in the N-terminus that is highly conserved and when mutated significantly reduces Cdx2 inhibition of beta-catenin/TCF transcriptional activity ... Considering the pivotal role of beta-catenin/TCF activity in driving proliferation of normal intestinal epithelial and colon cancer cells, our findings suggest a novel mechanism for Cdx2 mediated regulation of Wnt/beta-catenin signaling and cell proliferation
