To recognize the cancer cells with EMT phenotype, we have performed immunostaining for CDH1, CDH2, NAT1, SNAI2, TWIST1, VIM, and ZEB1. We were not able demonstrate the significant difference between EMT-activated and not-EMT-activated group regarding CDH1, CDH2, SNAI2, VIM, and ZEB1 expression, in the tumor bulk as well as at the invasive edges of the tumor tissue. This evidence concerns the gene SNAI2 and cancer.
