Figure 2. Venn diagrams of differentially up-regulated genes in the RS (4060) and the RR (20037) cell line, grouped according to the pathway or the biological process affected, 4 and 24 h after 2 Gy irradiation.

(A) Differentially up-regulated genes related to the pathway “DNA damage response”. (B) Differentially up-regulated genes related to the pathway “direct 53 effectors”. (C) Differentially up-regulated genes related to biological processes of apoptosis.
