Sestrin2 and MMP9 expression in airway tissue and serum in control and COPD group. Notes: a Expression of sestrin2 by IHC in control and patients with COPD. b Expression of MMP9 by IHC in control and patients with COPD. c Semiquantitative assessment of sestrin2 expression using Image-Pro Plus. d Semiquantitative assessment of MMP9 expression using Image-Pro Plus. e Serum sestrin2 concentrations in control and COPD groups. f Serum MMP9 concentrations in control and COPD groups; positive protein staining appears brown and nuclear staining appears blue.
