Western blot analysis of LCN2 (25 kDa) protein in the lung of control and irradiated animals at different time points. β-actin (42 kDa) was used as the loading control (a). Densitometric analysis of Western blots was performed to show the changes in protein expression of LCN2 (b). Results are shown as fold change ± SEM (* p ≤ 0.05, ** p ≤ 0.005, n = 3).
