ARHGEF5 KD attenuates TGF-β-induced EMT and cell migration in MCF10A cells. (a) ARHGEF5 was knocked down with shRNAs (shGEF5 no. 1 and shGEF5 no. 2) in MCF10A cells. Mock and ARHGEF5 KD cells were treated with or without TGF-β1 for 24 h and the levels of the indicated proteins analyzed by western blotting. (b) Mock and ARHGEF5 KD cells were treated with or without TGF-β1 for 48 h and the cells stained with anti-N-cadherin or anti-E-cadherin. Scale bar: 20 μm. (c) Mock and ARHGEF5 KD cells were treated with or without TGF-β1 for 24 h and subjected to wound-healing assays. Scale bar: 200 μm. (d) The migration rates of the indicated cells are shown. Values represent the mean±s.d. (n=3, ***P<0.001).
