SMAD7 and melanoma: Regulation expression of miR200c and ZEB1 in B16F10 cells positively led to expression changes of TGF-β, Vimentin, ZEB-1, N-cadherin, SMAD-7 and E-cadherin in tumor tissues from the B16F10/GPI-IL-21 vaccination of mice, which are correlated with progression of EMT of B16F10 cells as well as influence of melanoma growth and metastasis in mice.
