Figure Lengend Snippet: FFPE lung tissue sections from control and COPD donors were stained using immunohistochemistry for ECM and ECM-associated proteins with specific signals being detected with Nova red (red) and counterstained with hematoxylin (blue). Sections were scanned at 40x magnification using a digital slide scanner. Scale bar = 400um. Images are representative of protein detection patterns seen in control donors (n=18), SEO-COPD (n=12), and moderate COPD (n=14). ECM: extracellular matrix; SEO-COPD: Severe early-onset COPD patients; FFPE: formalin fixed paraffin embedded; COL1A1: collagen type I α chain 1; COL6A1: collagen type VI α chain 1; COL6A2: collagen type VI α chain 2; COL14A1: collagen type XIV α chain 1; FBLN2: fibulin 2; FBLN5: fibulin 5; LTBP4: latent transforming growth factor binding protein 4; LUM: lumican; DCN: decorin; VCAN: versican; ELN: elastin.

Article Snippet: Following PBS washes, primary antibodies diluted in 1% BSA/PBS for FBLN5 (1:8000, Mouse Anti-Fibulin 5/DANCE Antibody 1G6A4, Novus Biologicals), DCN (1:1500, Mouse Anti-Dermatan Sulfate Proteoglycan Antibody 6B6, Seikagaku), VCAN (1:200, Mouse Anti-Versican Antibody 2B1, Seikagaku), and ELN (1:400, Rabbit Anti-Elastin Antibody CL55011AP, Cedarlane Labs) were added to the respective sections for 1 hour at room temperature.

Figure Lengend Snippet: ECM proteins in FFPE tissue sections from controls (n=18), SEO-COPD (n=12), and moderate COPD (n=14) were detected using immunohistochemistry. Parenchyma was isolated and analyzed for percentage positive tissue area and mean intensity of positive pixels of expression for each protein. All 44 donors were available for analysis of COL1A1, COL6A2, FBLN2, LTBP4, LUM, DCN, VCAN, AND ELN, while for COL6A1, COL14A1, and FBLN5 43 donors were available. For each protein, regression coefficients (± 95% CI) were obtained following linear regression and a p value of <0.05 was considered significant. Non-transformed variables are plotted first, followed by log transformed variables. The differences in ECM and ECM-associated proteins in COPD tissue were compared to control in terms of A-C) percentage area and D-F) mean intensity of positively stained pixels. Dark blue-colored bars in light blue colored boxes highlight significant differences.

Figure Lengend Snippet: ECM proteins present in FFPE tissue sections from controls (n=18), SEO-COPD (n=12), and moderate COPD (n=14) were detected using immunohistochemistry. Airway walls were isolated and analyzed for percentage area and mean intensity of expression for each protein. The number of airway walls available for the analysis for each protein were COL1A1 (n= 155), COL6A1 (n=150), COL6A2 (n=149), COL14A1 (n=152), FBLN2 (n=158), FBLN5 (n=173), LTBP4 (n=163), LUM (n=158), DCN (n=156), VCAN (n=165), and ELN (n=158).
