Target Background

Transcription factor which regulates the transcription of multiple genes expressed in the intestinal epithelium. Binds to the promoter of the intestinal sucrase-isomaltase SI and activates SI transcription. Binds to the DNA sequence 5'-ATAAAAACTTAT-3' in the promoter region of VDR and activates VDR transcription. Binds to and activates transcription of LPH. Activates transcription of CLDN2 and intestinal mucin MUC2. Binds to the 5'-AATTTTTTACAACACCT-3' DNA sequence in the promoter region of CA1 and activates CA1 transcription. Important in broad range of functions from early differentiation to maintenance of the intestinal epithelial lining of both the small and large intestine. Binds preferentially to methylated DNA.

  6. CDX2 is highly expressed along the atrophic gastritis-metaplasia-dysplasia-cancer sequential. Though CDX2 expression is quite dominant in IM ( intestinal metaplasia), but its expression is not associated with H. pylori (Helicobacter pylori) infection. PMID: 29132476
  7. of CDX2 using a hypoxia-inducible hTERT promoter-driven vector suppressed malignant progression of colon cancer cells in vitro and in vivo.These results suggest that pLVX-5HRE-hTERTp-CDX2-3FLAG gene therapy may be a promising novel approach to treat colon cancer PMID: 28627695
  8. The results of the present study show that a lack of CDX2 expression in metastatic colorectal cancer is an adverse prognostic feature and a potential negative predictor of the response to chemotherapy. PMID: 27726953
  9. We may conclude that hTERT promotes GIM by up-regulating CDX2 via NF-kappaB signaling pathway. PMID: 28460480

  11. AMPK enhances intestinal barrier function and epithelial differentiation via promoting CDX2 expression, which is partially mediated by altered histone modifications in the Cdx2 promoter. PMID: 28234358
  12. Findings suggest that H. pylori infectionis a driving force of gastric cardia carcinogenesis by upregulating caudal-related homeobox transcription factor 2 (CDX2) and inducing inflammation. PMID: 27384681
  13. Data show that a two-marker panel of p40 (DeltaNp63) and CDX2 is highly sensitive and specific. PMID: 29187465

  18. A small subset (5%) of hepatocellular carcinomas are CDX2 positive. PMID: 28089540
  19. A new organ culture system for adult murine oesophagus is described. Using this, Cdx2 and HNF4alpha were ectopically expressed by adenoviral infection. We demonstrate the expression of CDX2 and HNF4alpha in human biopsy samples. PMID: 27875772
  20. Colon cancer cells expressing CDX2 are less deformable, a feature that has been shown to correlate with poor metastatic potential. PMID: 27816490
  21. Results show that CDX2 and Fbw7 expression is inversely correlated during colon cell differentiation and that CDX2 expression is regulated by Fbw7 in a GSK3b-dependent manner. PMID: 27470268
  22. Aberrant DNA methylation of SOX2 and CDX2 genes contributes to the development of IM. Notably, SOX2 may play a role in establishing and maintaining the methylation status of the CDX2 gene in gastric tissues and cells. PMID: 27913994
  23. Strong expression of CDX2 was demonstrated only in the mature colonic epithelium of teratomas in both primary and metastatic germ cell tumors of the testis. PMID: 28322096
  24. Cdx members interact with the SWI-SNF complex and make direct contact with Brg1, a catalytic member of SWI-SNF. Both Cdx2 and Brg1 co-occupy a number of Cdx target genes, and both factors are necessary for transcriptional regulation of such targets. Finally, Cdx2 and Brg1 occupancy occurs coincident with chromatin remodeling at some of these loci. PMID: 28082674
  25. we found that the loss of CDX2 expression in colorectal cancer is inversely related with the methylation of CDX2 promoter. The methylation of the CDX2 promoter was associated with enhanced lymph node metastases and shorter survival time ( p = 0.0273), but was independent of tumor stage, tumor differentiation, gender, and age. PMID: 27754705
  26. PAX2, PAX8, CDX2 immunostains was preformed to the TMA slides. PMID: 26797858
