    TEAD1 and TEAD4 regulate HPV early gene expression. (A to F) W12 (A and D), CaSki (B and E), and HeLa (C and F) cells were transfected with the indicated siRNA. At 2 days after transfection, the levels of <t>HPV16</t> E6*I and E1̂E4 mRNAs (A and B) and HPV18 E6*I mRNA (C) were quantified by RT-qPCR and normalized to the level of GAPDH mRNA. The HPV16 E7 (D and E) and HPV18 E7 (F) proteins were detected by immunoblotting with anti-HPV16 and anti-HPV18 E7 antibodies, respectively. The effects of siRNA were verified by immunoblotting with anti-TEAD1 and anti-TEAD4 antibodies. β-Actin was used as the loading control. (G and H) CaSki (G) and HeLa (H) cells were transfected with the indicated siRNAs. Six hours later, the transfected CaSki and HeLa cells were further transfected with pGL3-P97 and pGL3-P105, respectively, together with the Renilla luciferase plasmid. At 2 days after transfection, firefly luciferase activity was measured and normalized to the Renilla luciferase activity after background subtraction. The quantitative data are the averages from three independent experiments, with the error bars representing the standard deviations. P values were determined by Student’s t test. NS, not significant (P > 0.05); *, P < 0.05; **, P < 0.01; ***, P < 0.005.

The quantitative data are averages from three independent experiments, with error bars representing standard deviations. P values were determined by Student's t test. *, P < 0.05; ***, P < 0.005. (E) HEK293 cells transfected with the indicated expression plasmids were analyzed for the expression of HA-VGLL1 (or HA-VGLL1/HFm) and TEAD1 by immunoblotting with anti-HA and anti-TEAD1 antibodies. β-Actin was used as the loading control. (F) HEK293 cells that had been transfected with the indicated expression plasmids were cultured in medium containing cycloheximide (CHX). The cells were collected at the indicated time points, and the levels of HA-VGLL1 and TEAD1 proteins were detected by immunoblotting with anti-HA and anti-TEAD1 antibodies, respectively. β-Actin was used as the loading control. Long- and short-exposure images of the same blot are shown for HA-VGLL1. (G) The levels of HA-VGLL1 in panel F were quantified with Image Lab software (Bio-Rad) and plotted on the graph. The data are presented as the relative level of HA-VGLL1 compared to that in cells without cycloheximide treatment (0 h).

    Article Snippet: To generate pGL3-P97, we used PCR to synthesize a DNA fragment spanning from nt 7451 to 101 of the HPV16 genome (forward primer, 5′-AAG CTT ACC GAA TTC GGT TGC ATG CT-3′; reverse primer, 5′-CCA TGG CAG TTC TCT TTT GGT GCA TA-3′) and cloned this PCR product between the HindIII and NcoI sites of pGL3-Basic (Promega, Madison, WI, USA). pGL3-P105, which contains the HPV18 LCR fragment (from nt 6982 to 102), was similarly constructed using the following primers: forward primer 5′-AAG CTT CTT TAG ACT TAG ATC AAT AT-3′ and reverse primer 5′-CCA TGG TAT TGT GGT GTG TTT CTC ACA-0.3′.
