(B) Western blot analysis of SIRT3 expression in the lung tissues from bleomycin (BLM)-treated mice. n = 3, ∗ P < 0.05. (C) Western blot analysis of the acetylation levels of FoxM1 in SIRT3 flox/flox mice intratracheally injected with AAV-Cre. n = 3, ∗ P < 0.05. (D) Western blot analysis was performed to assess the acetylation status of FoxM1 in pulmonary fibroblasts following transfection with Sirt3 siRNA (si-Sirt3). n = 3, ∗ P < 0.05. (E) Western blot analysis of FoxM1 expression in CHX-treated pulmonary fibroblasts transfected with or without si-Sirt3. n = 3, ∗ P < 0.05. (F) Western blot analysis of CTHRC1, α-SMA and Collagen I expression in pulmonary fibroblasts transfected with or without si-Sirt3. n = 3, ∗ P < 0.05. (G) EdU assay for the proliferation of pulmonary fibroblasts transfected with or without si-Sirt3. n = 3, ∗ P < 0.05. (H) Western blot analysis of FoxM1 acetylation, CTHRC1, α-SMA, and Collagen I expression in TGF-β1-treated pulmonary fibroblasts transfected with or without LV-Sirt3. n = 3, ∗ P < 0.05. All data were presented as the means ± SEM. Paired t -test (B-D, F, G) and one-way ANOVA with Tukey's post-hoc test (E, H) were used for statistical analysis.
