Effect of YAP on HPV16 E6 stimulation of HT3 cell proliferation. siCtrl: non-targeting control siRNA; siYAP: YAP siRNA; E6: 400 nM recombinant HPV16 E6, 48 h. Each bar represents mean ± SEM (n = 4). Bars with the same letters are not significantly different from each other (siCtrl vs. siCtrl+E6, P = 0.0232; siCtrl+E6 vs. siYAP+E6, P = 0.0011).
