β-catenin expression after PD98059 drug treatment. Prostate cells (PNT1A) were plated in six well plates. They were then transfected with empty expression vector or expression plasmid pSG5/HA-dETV1 and pSG5/β-catenin as indicated. Cells were transfected with different concentrations of β-catenin and dETV1 (β-catenin: 0.2 μg, Low dETV1: 0.6 μg, High dETV1: 1.6 μg). After 24 hours of incubation, cells in lane 2, 4, and 6 were treated with PD98059, a kinase inhibitor and cell lysate was collected and subjected to Western blot analysis. Densitometry analysis was done with Image Gauge software.
