Figure 4. — Effect of UVB on XPD expression. Keratinocytes were harvested at the indicated time points after irradiation. (A) Total protein extracts were assessed for the presence of the XPD protein by western blot. β-actin was used as a loading control. (B) The protein bands corresponding to XPD were quantified densitometrically. (C) the relative levels of XPD mRNA were quantified by qRT-PCR. The results are expressed as the mean±SD of three independent experiments. *P < 0.05 for cells at the indicated time point versus non-transduced cells prior to irradiation. **P < 0.05 for transduced cells versus corresponding non-transduced cells.
