Knock down of CyP inhibits HPV16 infection.

<p>293TT (A,B) or HaCaT (C,D) cells were transfected with indicated siRNA and infected with HPV16 pseudovirus 48h after transfection. Infection was scored at 72 hpi. Representative graphs based on six replicates are shown (A,C). Knockdown of CyPA and CyPB was confirmed by Western blot prior to infection (B,D). Numbers indicate percent levels of protein after correcting for input (D). *: p<0.05; **: p<0.01.
