Fig. 4.
Altered secretoglobulin family 1A member 1 (Scgb1a1) expression in lungs from Scgb1a1Cre/+;autophagy-related 5 (Atg5f/f) mice after naphthalene injury. A–D: representative images of lung sections from Atg5f/f and Scgb1a1Cre/+;Atg5f/f mice 14 days after naphthalene administration. Sections were stained with hematoxylin and eosin (A and B) or immunostained for Scgb1a1 (red) and acetylated-α-tubulin (AAT, green); nuclei were stained with bis-benzamide (blue) (C and D). Scale bars = 100 µm. E and F: percentage of Sgcb1a- and AAT-positive airway cells. Values are means ± SE; n = 5–8 mice/group performed in 2 separate experiments. **P < 0.01 (by one-way ANOVA and Tukey's multiple comparison test); ns, not significant.
