miR-200c/ZEB1/E-cadherin signal pathway regulates the epithelial-to-mesenchymal transition in breast cancer cells.

<p>Re-expression of miR-200c in breast cancer cells results in up-regulation of E-cadherin expression and the down-regulation of ZEB1 expressions as assessed by using Western Blot analysis (<b>A</b>) and RT-PCR (<b>B</b>). siRNA knockdown of the expressions of ZEB1 results in up-regulation of E-cadherin expression in breast cancer cells (<b>C</b>).
