In CRC cell lines, the radiation triggers molecular changes consistent with EMT, such as low expression of the epithelial marker E-cadherin and high expression of mesenchymal markers, such as vimentin, fibronectin, and the Snail Family Transcriptional Repressor 2 (SNAI2), increasing invasion, migration, and survival of the radiated cells (105). This evidence concerns the gene SNAI2 and colorectal carcinoma.
