Figure 2.
p45 NFE2 and p18 NFE2 tyrosine phosphorylation in human ATII cells and lung tissue obtained from control non-smokers (NS) and smokers (SM) and patients with emphysema (E). Immunoprecipitation was performed in freshly isolated ATII cells (A) and lung tissue (B) followed by Western blotting analysis. Densitometric quantification is also shown. *Statistically significant difference (p < 0.05). Data are shown as the mean (±s.e.m.).
