HPV E6 increases thymine dimer persistence and DSB prevalence following UVB exposure.

<p>A. HFK cells were exposed to 10 mJ/cm² UVB and immunofluorescence was used to measure the percentage of cells positive for thymine dimers above background. B. HT1080 cells were exposed to 10 mJ/cm² UVB and immunofluorescence was used to measure the percentage of cells positive for thymine dimers above background. C. HFK cells were exposed to 10 mJ/cm² UVB and immunofluorescence was used to measure the percentage of cells positive for phospho H2AX above background. D. HT1080 cells were exposed to 10 mJ/cm² UVB and immunofluorescence was used to measure the percentage of cells positive for phospho H2AX above background. For all portions of this figure, n≥5, error bars represent standard errors of the mean.
