VIM and neoplasm: It was found that the expression of TGF-β, Vimentin, ZEB-1 and N-Cad was significantly decreased in tumor tissues from the B16F10/GPI-IL-21 vaccination of mice challenged by the B16F10/miR200c cells compared with other groups, whereas the expression of SMAD-7 and E-cadherin was significantly increased in tumor tissues, and the differences were statistically significant as are shown in Figures 4B-C.
