Figure 4. Targeted knockdown of MRP leads to establishment of adherens junctions.
a) Bright field imaging of EpRas, C1, E13, and E14 at 10X. b) EpRas, C1, E13 or E14 cells were stained with primary antibodies specific to either E-cadherin (Becton Dickinson), APC (Calbiochem) or β-catenin (Becton Dickinson) and secondary antibodies Alexa fluor 488 anti-rabbit or anti-mouse (Invitrogen). Images at 100X c) Western blot analysis of EpRas, C1, E13, E14 whole cell lysates and immunoblotted with antibodies to Ras (Cell Signaling), E-cadherin and β-catenin (Becton Dickinson), and γ-tubulin (Sigma). NS = non-specific. d) Indicated cells transfected with the TCF luciferase reporter construct TOPFLASH and transfection control pRL-CMV were treated with 0, 50 ng/mL or 100 ng/mL of recombinant WNT3a for 18 hours. All data is mean of three independent experiments ± SD.
