VASP phosphorylation, profilin1 and cofilin1 level in lung tissue homogenates from mouse pups exposed to hyperoxia until day 7. Western blot analysis was performed on whole lung tissue homogenates obtained from mice exposed to room air (RA, open circles) or 85% O₂ (O₂, closed triangles) from birth through day 7 or at day 56 after 14 days of hyperoxia exposure and 42 days of room air recovery. Band intensity was quantified by densitometry and statistical analysis was performed using two-way ANOVA with Tukey’s post hoc, n = 4 in each group. *, p < 0.05 and n.s. = non significant
