CDH1 and lung carcinoma: We then investigated the impact of BC on EMT in lung cancer cells and found that the expression levels of Slug, N‐cadherin, Snai1 and ZEB1 were significantly elevated in BC‐overexpressing 95C, 95D, A549 or PC9 cells, whereas that of E‐cadherin was robustly reduced (Figures 2D and S4B).
