Figure 3

The mRNA expression of (A) TNF-α, (B) IL-6, (C) IL-1α, and (D) IL-1β according to radiation exposure. The mRNA expressions of pro-inflammatory cytokines were higher in the IR only groups compared to the controls with/without statistical significance, whereas it was significantly lower in the IR + GL groups than the IR only groups. Results are expressed as means ± SEM from duplicate experiments (n = 5) performed in each group. The asterisk (*) indicates significant differences between the control and IR groups (both IR only and IR + GL). The hash sign (#) indicates significant differences between the IR only groups and IR + GL groups. ***p < 0.001, ##p < 0.01, ###p < 0.001. IR irradiation, GL glycyrrhizin.
