Fig. 5. ARO inhibits MAPK activation in experimental COPD mice. (A) The activation of JNK, p38, and ERK in lungs of mice was analyzed using western blotting. Quantitative analysis of (B) p-JNK, (C) p-p38, and (D) p-ERK was performed using ImageJ software. Data are expressed as the mean ± SD (^#p < 0.05 for comparison with normal control; *p < 0.05 for comparison with COPD group). NC: normal control mice; COPD: cigarette smoke exposed/LPS-administered mice; ROF: 5 mg/kg ROF-treated COPD mice; ARO 5: 5 mg/kg ARO-treated COPD mice; and ARO 10: 10 mg/kg ARO-treated COPD mice.
