NF-κB activity in response to Wortmannin. HEC 1-A, RL 95-2 and Ishikawa cells were treated with Wortmannin for 24 hours and cells were recovered and lysed. Nuclear cell lysates were recovered and NF-κB activity was measured using the Chemiluminescent NF-κB Assay. Data represent the mean ± SEM of 4 independent experiments. * p < 0.05 compared to control.
