Purpose: Transforming growth factor-??induced epithelial?mesenchymal transition (EMT) is one of the main causes of posterior capsular opacification (PCO) or secondary cataract; however, the signaling events involved in TGF-??induced PCO have not been fully characterized. Here, we focus on examining the role of ?-catenin/cyclic AMP response element?binding protein (CREB)-binding protein (CBP) and ?-catenin/T-cell factor (TCF)-dependent signaling in regulating cytoskeletal dynamics during TGF-??induced EMT in lens epithelial explants. Methods: Rat lens epithelial explants were cultured in medium M199 in the absence of serum. Explants were treated with TGF-?2 in the presence or absence of the ?-catenin/CBP interaction inhibitor, ICG-001, or the ?-catenin/TCF interaction inhibitor, PNU-74654. Western blot and immunofluorescence experiments were carried out and analyzed. Results: An increase in the expression of fascin, an actin-bundling protein, was observed in the lens explants upon stimulation with TGF-?, and colocalized with F-actin filaments. Inhibition of ?-catenin/CBP interactions, but not ?-catenin/TCF interactions, led to a decrease in TGF-??induced fascin and stress fiber formation, as well as a decrease in the expression of known markers of EMT, ?-smooth muscle actin (?-SMA) and matrix metalloproteinase 9 (MMP9). In addition, inhibition of ?-catenin/CBP?dependent signaling also prevented TGF-??induced downregulation of epithelial cadherin (E-cadherin) in lens explants. Conclusions: We show that ?-catenin/CBP?dependent signaling regulates fascin, MMP9, and ?-SMA expression during TGF-??induced EMT. We demonstrate that ?-catenin/CBP?dependent signaling is crucial for TGF-??induced EMT in the lens.
