Sodium butyrate treatment attenuates radiation-induced lung injury. (A) Hematoxylin and eosin staining of lung tissues 1 week after radiation administration. Scale bar 100 μm. (B) The protein levels of p-PI3K, PI3K, p-AKT and AKT in lung tissue were detected by Western blot. (C, D) Quantitative analysis of (B). Results are representative of three independent experiments, and the differences between data were evaluated by one-way ANOVA, with p value less than 0.05 considered statistical significance. **p < 0.001 vs. Control; ^## p < 0.05 vs. IR.
