<p>A, B. HPV16 E7 siRNA was used to inhibit E7 expression in CaSki cells and Western blot analysis performed to analyse HPV E7 (A) and Rb (B) levels after HPV E7 knock-down. C, D. Kpnβ1 (C) and Kpnα2 (D) promoter activities were measured after E7 siRNA transfection, and were found to be significantly inhibited after HPV E7 inhibition. E, F. Rb was overexpressed in CaSki cells and Kpnβ1 (E) and Kpnα2 (F) promoter activities were found to be significantly inhibited. Results shown are the mean ± SE of experiments in quadruplicate performed at least two times (* p<0.05).</p
