**Figure 4. **Blocking ERK1/2 signaling prevented moderate H_{2}O_{2}-induced EMT in LECs. **A**: Western blotting of epithelial-mesenchymal transition (EMT) biomarkers, including E-cadherin, vimentin, α-SMA, and Snail.
**B**: Immunofluorescent image of vimentin. Statistical analysis was performed with the paired Student *t* test using the integrated density of the protein band (*p<0.05 and **p<0.01). The data are shown as mean ± standard error
of the mean (SEM) with n = 3.
