Figure 5. Univariate data analysis on metabolomic markers of γ-irradiated HepG2 cells.
Data are presented as means ± standard deviation (S.D.). Data were analyzed by one-way ANOVA for each metabolite with Bonferroni’s correction for multiple comparisons. ANOVA was significant at P < 0.0001. There were no statistically significant differences between the sham irradiated and 1 Gy γ-irradiated samples for any metabolite. * means P < 0.05; ** means P < 0.01; *** means P < 0.001; n.s. means not statistically significant. Relative concentrations were calculated as the peak area of each metabolite divided by the peak area of the internal standard and are based upon 4 × 106 cells.
