A. Paf15 expression at 0, 24 and 48 hours after radiation was measured using RT-PCR (A) and Western blot B. with GAPDH expression as a control. C. DNA damage at 48 hours after radiation was compared for different Paf15 expression levels by comet assay. D. DNA damage measured by comet tail length of each measured cell. Increased Paf15 expression resulted in a reduction of DNA damage after radiation (P<0.05).
