Expression and activity of MMP-9 in the lung and the pro-inflammatory cytokines in the BAL fluid. (A and B) Levels of MMP-9 mRNA and activity in the lung tissue from differently treated mice; (C and D) Concentration of IL-17 and IL-6 in BAL fluid from differently treated mice. Data are expressed as the mean + standard error (n=10 per group). *P<0.05 compared with the Ctr group mice; †P<0.05 compared with the sepsis group mice; ‡P<0.05 compared with the Sc group mice. IL, interleukin; MMP-9, matrix metalloproteinase 9; BAL, bronchoalveolar lavage; Ctr, control; Sc, scrambled control group; siRNA, small interfering RNA.
