Accordingly, E-cad expression were decreased in tumor issues of A549cisR cell-derived xenografts compared to tissues of A549P cell-derived xenografts (Fig. 6f), while the expressions of N-cad, Vimentin and Snail were higher in tissues of A549cisR cell-derived xenograft tumor than in A549P cell-derived xenografts tumor (Fig. 6f). Here, SNAI1 is linked to neoplasm.
