**Figure 4. **Inhibition of extracellular signal-related kinase 1/2 decreases lens epithelial cell proliferation. Lens epithelial cells
(LECs) were exposed to 10 μM U-0126 for 10 min followed by the addition of 1 μCi/ml [3H]thymidine for 24 h. Each histogram
bar represents the mean±SEM of at least six samples. *p=0, significantly different from control. Statistical tests for all
data included ANOVA and Tukey’s test.
