Relative gene expression of NER component genes uvrA, uvrB, and uvrD at 5 min (filled with dots), 20 min (filled with diagonal stripes), and 60 min (filled with lines) after UVC (A), UVB (B), and UVA (C) irradiation. Ratios for UVR-irradiated samples and unirradiated samples were taken at the same time points. Each datum is the mean (± the standard error of the mean) of 8 to 12 data points from three biological replicates and two technical replicates.
