NFKB1 and colorectal carcinoma: Resveratrol chemosensitizes CRC cells to 5-FU through inhibition of EMT (epithelial–mesenchymal transition) factors (vimentin and SNAI2 proteins), up-regulation of intercellular junctions (desmosomes, gap and tight junctions, and adhesion molecules such as E-cadherin) and by down-regulation of NF-kB pathway (Table 1; Buhrmann et al., 2015).
