Fig. 4From: let-7i inhibits proliferation and migration of bladder cancer cells by targeting HMGA1(a) and (b) The lateral migration of cell lines T24 and 5637 transfected with let-7i mimic and negative control was examined by the cell scratch assay. (c) and (d) The graph represents the mean of wound closure rates ± SEM in cell lines T24 and 5637 transfected with let-7i mimic and negative control. (***P < 0.001)Back to article page
