Tissue IL-1β level relative expression, 1 and 2 h after irradiation, shows the effects of the mock irradiation (white—control), GPC-treated mock irradiation (white hatching), irradiation (gray), and GPC treatment with irradiation (gray cross-hatching). *p < 0.05 relative to GPC-treated and irradiated group. #p < 0.05 relative to the GPC-treated group. °p < 0.05 relative to control group. IL-1β, interleukin-1β.
