Hyperoxia enhances inflammation in acute lung injury. Mice were randomly divided into two groups: sham and hyperoxia. Mice in hyperoxia group were exposed to over 90% oxygen for 24 h. a IL-6, TGF-β1, IL-17A and IL-17RA protein levels in lung tissues were measured by western blotting. Histogram shows densitometry quantification of IL-6, TGF-β1, IL-17A and IL-17RA normalized to β-actin. Data are shown as mean ± SEM. n = 3 per group. ^*P < 0.05, ^**P < 0.01, ^***P < 0.001. ^*Compared with the sham group
