A. Transfected Bic-1 cells were treated with 5μM of 2-ME2 for 24 h or left untreated. Equal amounts of cell lysates (100μg/lane) were analyzed by Western blotting with an antibody against E-cadherin. Quantification of each band was performed by densitometry analysis software. * p<0.005 vs mismatched controls. ** p<0.01vs shRNA alone transfected cells.
B. E-cadherin and β-catenin shRNA transfected Bic-1 cells were exposed to 5 μM of 2-ME2 for 24 h, and β-catenin (left panel) and E-cadherin (right panel) mRNA expressions were determined by northern blotting using nonradioactive DIG-labeled probe. GAPDH is used as loading control.
