Effect of ANXA1 on the proliferation of BEC. (A) Reverse transcription-quantitative polymerase chain reaction was used to test the mRNA expression of ANXA1. (B) The protein expression of ANXA1 was determined by (C) western blotting. (D) Cell Counting Kit-8 assay was performed to analyze the effect of ANXA1 on BEC. The cells were treated with 64 µM Bap for 6 h to establish the cell injury model. *P<0.05 and **P<0.01 vs. control group; ^#P<0.05 and ^##P<0.01 vs. E.V.+Bap group. ANXA1/Anx, Annexin A1; BEC, bronchial epithelial cells; Bap, benzo[a]pyrene; E.V., empty vector.
