Effects of lipoxin A₄ on protein expression of CFTR in primary ATII cells. The cells were treated with lipoxin A₄ (100 nM) in the presence of LPS (1 μg/mL) for 6 hours. (a) After incubation, the cells were harvested, sonicated and CFTR protein detected by western blotting. (b) The protein expression of CFTR also was detected by immunofluorescence assay. Data were expressed as mean ± SEM for each group. *P < 0.05 versus control group, ^# P < 0.05 versus LPS group, n = 4 for each group. LPS = lipopolysaccharide, LXA₄ = lipoxin A₄, CFTR = cystic fibrosis transmembrane conductance regulator.
