Yang et al. [48] selected multiple EMT-related genes from the molecular signature information database and analyzed the correlation with CRC prognosis, metastasis, drug efficacy, and immunity by bioinformatics, and finally found nine EMT-related genes, including FGF8, NOG, PHLDB2, SIX2, SNAI1, TBX5, TIAM1, TWIST1, and TCF15. This evidence concerns the gene SNAI1 and colorectal carcinoma.
