Glycyrrhizin inhibits the phosphorylation of Jak2 and Stat3. The phosphorylation level of Jak2 was detected by western blot in the three experimental groups, respectively. ^∗∗p < 0.01, as compared to the model control (a). The phosphorylation level of Stat3 was detected by western blot in the three experimental groups, respectively. ^∗∗p < 0.01, as compared to the model control (b). β-Actin was used as an internal control. p value was calculated by t-test between glycyrrhizin treatment and DMSO treatment (model). “NC” represents lung tissue from normal mice. Stars are showing p values between model and glycyrrhizin.
