High impact information on Cdx1

  • METHODS: Cdx1 expression was induced in IEC-6 intestinal epithelial cells by stable transfection, and subsequent changes in cell growth, resistance to apoptosis, migration, and differentiation were monitored [1].
  • Cdx1 promotes differentiation in a rat intestinal epithelial cell line [1].
  • RESULTS: Compared with control, IEC-6/Cdx1 cells proliferated more rapidly, were more resistant to apoptosis, and migrated 3-4 times faster, as shown by an in vitro wound assay [1].
  • CONCLUSIONS: Cdx1 expression in IEC-6 cells induces phenotypic changes characteristic of differentiating enterocytes, suggesting an important role for Cdx1 in the transition from stem cells to proliferating/transit cells [1].
  • Cdx1 might carry out that function in the intestinal epithelium because its expression is specific to that tissue and increases during development [1].

Biological context of Cdx1

  • On the other hand, inhibition of the PAP I expression in the IEC-6 Cdxl-expressing cells using an antisense strategy confirmed the requirement of this protein for the effect of Cdx1 on cell growth [2].
  • Expression of the Cdx1 homeobox gene in epithelial intestinal cells promotes cellular growth and differentiation [2].
  • After stable transfection with a Cdx1 expression vector, they produce high levels of the PAP I transcript and protein indicating a functional link between the two genes [2].
  • These effects were accompanied by the increased formation of spermidine and spermine due to the enhancement of S-adenosylmethionine decarboxylase activity and by the upregulation of Cdx-1, a homeobox gene with oncogenic potentials [3].

Anatomical context of Cdx1


Associations of Cdx1 with chemical compounds

  • Cdx1 and Cdx2, known to be transcriptional factors related to intestinal proliferation and differentiation, were more highly expressed in STZ, OLETF and GK rats than in the respective controls [4].
