Statistical analysis was performed by one-way ANOVA followed by Dunnett’s multiple comparisons test. B-E: Western blotting of E-cadherin and α-SMA expression. Statistical analysis was performed by paired Student t-test using the integrated density of the protein bands (* p<0.05, ** p<0.01). The data were shown as mean ± SEM with n=3.
