Fig. 2. ADEs promote EMT of ovarian cancer cells in vitro.
A2780, CAOV3, ES2 and SKOV3 ovarian cancer cells were treated with 0 μg, 50 μg, and 100 μg of #7 ADEs. a Representative images of wound-healing assays of A2780 and SKOV3 and the area of wound closure was measured. Scale bar, 100 μm. b Representative images from migration and invasion assays of A2780 and SKOV3 cells. Scale bar, 100 μm. c Invaded and migrated cells were counted and are shown as histograms. d, e Changes in the morphology of A2780 and CAOV3 cells were evaluated by microscopic observation and F-actin staining. Scale bar, 100 μm (d), Scale bar, 20 μm (e). f Western blot analysis of E-cadherin, N-cadherin and Vimentin expressions in A2780, CAOV3, ES2 and SKOV3 cells. g Immunofluorescence analysis of E-cadherin, N-cadherin, and Vimentin in A2780 and CAOV3 cells. Experiments were performed in at least triplicate, and the results are shown as the mean ± s.d. values. Student’s t test was used to analyze the data (NS, not significant; *p < 0.05; **p < 0.01; ***p < 0.001). Scale bar, 20 μm.
