ZEB1 and breast cancer: To further demonstrate that miR‐200 family‐induced ZEB1 in EMT is a common phenomenon of BC, we texted the expression of ZEB1, E‐cadherin, and miR‐200 family members in multiple BC cell lines and found that miR‐200 family showed a global influence on ZEB1‐mediated EMT of BC cells (Figure 5H).
