Effect of EGF on the level of β-catenin expression. The concentration of β-catenin (CPM/105 cells). Although β-catenin concentrations tended to decrease initially (within the first hour) when exposed to EGF, no significant difference occurred between β-catenin levels within each cell line over the 24 hour time course of EGF treatment (F(7,205) = 1.72; p = 0.11). A significant difference however, was identified between the cell lines (F(4,208) = 8.13; p < 0.001), with WHCO3 differing from WHCO6 (p = 0.02) and SNO (p < 0.001), and WHCO5 from WHCO6 (p = 0.01) and SNO (p < 0.001).
