CSE promotes apoptosis of bronchial epithelial cells through LCN2. A Expression levels of LCN2 varied with different concentrations of CSE. B QPCR analysis of LCN2 levels in BEAS-2B cells transfected with NC, CSE, CSE + LCN2siRNA, and CSE + NCsiRNA. C Western blot analysis of LCN2. D Assessment of cell apoptosis in BEAS-2B cells transfected with NC, CSE, CSE + LCN2siRNA, and CSE + NCsiRNA. E The apoptosis rate was detected by Flow cytometry in different groups (*P < 0.05)
