SNAI1 and neoplasm: Consistent with our findings regarding the association of expression levels of the five EMT-related biomarkers with “tumorigenesis”, the expression of Snail (p = 0.009, S6 Table) and Twist (p = 0.001; S6 Table) were significantly higher in tumor tissues than in normal tissues, indicating that the high expression levels of Snail and Twist were reliable biomarkers for tumorigenesis.
