Figure 1. Induction of DNA repair genes at the exon level four hours after treatment with 10 Gy IR in LCLs.

The top five DNA repair genes: XPC (A), POLH (B), DDB2 (C), PCNA (D) and RRM2B (E) as identified using Partek Genomics Suite 6.6 statistical package. Relative fluorescence (y-axis; log₂) is plotted for each PSR (x-axis). Core PSRs are labelled numerically in a 5′ to 3′ direction (left to right). Samples were either sham irradiated (red) or irradiated (blue) with 10 Gy from a ¹³⁷Cs source. Arrow indicates the PSR region to which primers were designed for qRT-PCR used in figure 3A. Error bars = SEM (n = 12).
