B6F2D1/J female mice received 8.5 Gy 60Co gamma (RI) or 8.5 Gy followed by 15% total body surface area skin wound trauma 1 h after radiation (CI). The skin wound was to remove panniculus carnosus muscle and overlying skin (23.5 ± 1.1 mm in length and 14.9 ± 0.7 mm in width; see ref. 31). Gene expression in bone marrow 24 h after RI or CI was measured using real-time PCR. Each group contained 6 mice.
P < 0.05 vs. Sham, RI, and CI;
P < 0.05 vs. Sham, Wound, and CI;
P < 0.05 vs. Sham, Wound, and RI; determined by Chi-square test.
DDB2: DNA damage-binding protein 2; Gadd45α: Growth arrest and DNA-inducible protein 45α; TERT: Telomerase reverse transcriptase
