Figure 7. Ctr1 siRNA inhibits CoCl2-induced cytoskeleton remodeling and the expression of EMT marker genes.
(A) Representative images of fluorescently stained actin of MCF-7 cells under control, 200 μM CoCl2 or CoCl2 with Ctr1 siRNA treatment. Scale bars = 10 μm. (B) Expression of E-cadherin in MCF-7 cells maintained for 24 h under control, 200 μM CoCl2 or CoCl2 with Ctr1 siRNA treatment by indirect immunofluorescence staining. Scale bars = 50 μm. (C) Expression of vimentin in MCF-7 cells maintained for 24 h under control, 200 μM CoCl2 or CoCl2 with Ctr1 siRNA treatment. Scale bars = 50 μm. (D) The fluorescence density of E-cadherin and vimentin per cell were measured in each groups. Data was shown as mean ± SD of three independent experiments. p < 0.05 was considered statistically significant (*compared to the control group and #compared to the CoCl2 group).
