Knockdown of integrin α6 but not of integrin α3 strongly inhibits PsV binding. Two days after siRNA transfection, cells were incubated for 1 h at 0 °C with HPV16 PsVs, scraped from the substrate, washed, lysed and analyzed by Western blot. Full Western blots are shown in Fig. S16 (L1) and S17 (actin). Binding of viral particles was assayed by quantification of the L1 ~55 kDa band. The control value was set to 100% and used for normalization. Values are given as means ± SD (n = 4 independent experiments). Unpaired Student’s t-test, comparing control to knockdown conditions (***p < 0.001; *p < 0.05).
