CAE partially regulated COX2/PGE2 pathway. A The protein expression of COX2 was examined by western blots. B Quantitative analysis of COX2 expression (n = 3). C The content of PGE2 in media of A549 cells was examined by ELISA (n = 3). All data were presented as means ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001 vs. the TGF-β1 group, ^# P < 0.05, ^## P < 0.01,^### P < 0.001 vs. control group
