Figure 1

Overall expression of DNA-damage signaling genes in (parental, HPV-negative) FaDu cells and (HPV-positive) 2A3 cells after exposure to cisplatin (CDDP), radiation (IR) or their combination (CDDP+IR). Symbols are mean gene expression for each of the 84 DNA-damage signaling genes included on the Human DNA Damage Signaling Pathway RT2 ProfilerTM PCR Array from 3 independent experiments. The lines indicate the median gene expression of all tested genes.* p < 0.05; *** p < 0.001; **** p < 0.0001

2-D clustergram analysis of the expression of DNA-damage signaling genes in (parental, HPV-negative) FaDu cells and (HPV-positive) 2A3 cells after exposure to cisplatin (CDDP), radiation (IR) or their combination (CDDP+IR). Clusters observed at ¼ dendrogram branch height are shown as blocks of different color.

Figure 3

Deregulated expression of DNA-damage signaling genes in (parental, HPV-negative) FaDu cells and (HPV-positive) 2A3 cells after exposure to cisplatin (CDDP), radiation (IR) or their combination (CDDP+IR). Only significantly deregulated genes are shown. Symbols are the mean and SEM from three independent experiments.* p < 0.05; ** p < 0.01; *** p < 0.001
