In the case of ATM, the expression increased only after low-dose irradiation (1.8-fold change; p = 0.025), while the GADD45A expression showed an almost significant decrease 24 h after 2-Gy irradiation (0.4-fold change; p = 0.070) ( Figure 6 ).
Effects of Direct Irradiation and EV-Transfer from Irradiated Mice on Lipid Peroxidation in the Spleen Lipid peroxidation in the spleen of mice irradiated with 2 Gy was moderately (1.6-fold) increased as compared to the nonirradiated mice ( p = 0.033), and there was also a small, marginally significant (1.2-fold) increase ( p = 0.085) in lipid peroxidation in the spleen of mice irradiated with 0.1 Gy ( Figure 1 ).
