CDH2 and non-small cell lung carcinoma: One study found that the TGFβ‐activated SMAD3/4 complex upregulates N‐Cadherin expression in NSCLC cells and that SMAD3/4 expression was correlated with N‐Cadherin expression in a NSCLC cohort.51 Another in vitro assay showed that TGFβ could enhance VIMENTIN and SNAI2 expression in NSCLC cells.52 In the present study, we found correlations between the overexpression of TGB1 and EMT‐TFs SNAI1, SNAI2, ZEB1, TWIST1, and TWIST2, but with differences among N status.
