The expressions of JAK2, STAT3 and pSTAT3. a Representative western blots showed the expressions of JAK2 in the lungs of each group. b The intensity of JAK2 was normalized to GAPDH. c Representative western blots showed the expressions of STAT3 and pSTAT3 in the lungs of each group. d The intensities of STAT3 and pSTAT3 were normalized to GAPDH, and the ratio of pSTAT3/STAT3 was calculated. NS, not significant. *P < 0.05, **P < 0.01, ***P < 0.001 and ****P < 0.0001
