Costunolide regulates epithelial-to-mesenchymal transition-associated protein expression of H1299 lung cancer cells in vitro. (A) Following the treatment of H1299 cells with different concentrations of costunolide for 48 h, E-cadherin protein expression was increased, while N-cadherin was decreased. Representative blots are shown. (B) Data are presented as the mean ± standard deviation (n=3). Differences between concentrations were tested using one-way ANOVA and Tukey's post hoc tests. *P<0.05, **P<0.01; NS, not significant. Con, control.
