Figure 1. SOD3, AQP5, and pro-SPC proteins in control, moderate, and severe COPD lungs.

Figure 1

A. Two bands (32 and 30 kDa) are recognized by a specific polyclonal antibody against human SOD3 (Santa Cruz, sc-32219) via Western blot. The blots were stripped and reprobed with a monoclonal anti-β actin antibody. B. Quantitative densitometry of SOD3 relative to corresponding β actin. One-way ANOVA. *P<0.05 and ***P<0.001 vs control or moderate group. N = 17. C. Representative images of control, moderate, and severe groups. H & E stain. 10×. D. AQP5 proteins are detected by a specific antibody against human AQP5 (Santa Cruz, sc-28628) via Western blot. Pro-SPC is detected (21 kDa) using a specific antibody (Millipore, AB3786). E. Densitometric measurements of AQP5 over β actin. N = 17. *P<0.05 versus controls. F. Relative pro-SPC protein expression. One-way ANOVA. *P<0.05 versus controls and **P<0.01 versus moderate group.
