Fig. 7. Effect of hemin on the AMPK/SIRT1/PGC-1
α/HO-1/NF-κB signaling pathway in the lung tissue of mice with pulmonary fibrosis (PF). (A) Western blotting detection of the expression of proteins related to the AMPK/SIRT1/PGC-1α/HO-1/NF-κB pathway in the lung tissue of mice with PF. (B) p-AMPK/AMPK ratio. (C) SIRT1/GAPDH ratio. (D) PGC-1α/GAPDH ratio. (E) HO-1/GAPDH ratio. (F) p-NF-κB p65/NF-κB p65 ratio. The significance of difference was determined by one-way ANOVA followed by Tukey’s test. The data are presented as the means ± standard deviations. Three mice were in each group. AMPK, adenosine monophosphate-activated protein kinase; SIRT1, silent information regulator 1; PGC-1α, peroxisome proliferator-activated receptor-gamma coactivator-1α; HO-1, heme oxygenase-1; NF-κB, nuclear transcription factor-κB. **p < 0.01 compared with the control group. #p < 0.05 and ##p < 0.01 compared with the bleomycin group.
