Interestingly, various mRNAs such as BAMBI, a marker of metastasis in colon cancer (Fritzmann et al., 2009), insulin-like growth factor 2 (IGF2), inducible nitric oxide synthase (iNOS), fibronectin 1 (FN1), MMP-2, Notch2, uPAR, and Snai1 (also known as Snail1), which are all direct targets of TCF/β -catenin1, were found to be increased in the EVT pools concomitant with the upregulation of TCF-4 (Figure 3). This evidence concerns the gene SNAI1 and colonic neoplasm.
