Lung MMP and TIMP mRNA and protein expression. Changes in MMP2 (a), TIMP2 (b), MMP2/TIMP2 (c), MMP9 (d), TIMP1 (e), and MMP9/TIMP1 (f) in all groups treated with or without LPS. (g) Protein expression in each group as detected by western blotting. LPS 2h, 6h, 12h, and 24h indicate 2, 6, 12, and 24 hours after LPS injection in the acute lung injury group, respectively. Data are shown as mean ± standard deviation (n = 6 per group). *P < 0.05 vs. control, #P < 0.05 vs. LPS 2h. Control, normal control group; MMP, matrix metalloproteinase; TIMP, tissue inhibitor of metalloproteinase; LPS, lipopolysaccharide
