Figure 3. Levels of vimentin protein in rat lenses determined by western blot analysis. Vimentin protein levels in the whole lens were reduced in the group treated with dexamethasone (Dex; epithelium-D, fiber-D) compared with the control group (epithelium-C, fiber-C) and the group treated with Dex and RU486 (epithelium- R, fiber- R), which indicated RU486 prevented the reduced expression of vimentin protein induced by Dex . β-Actin was used as the control for protein loading. C: Control group; D: Dex group; R: RU486+Dex group.
