Fig. 8From: Suppressor of variegation 3–9 homologue 1 impairment and neutrophil-skewed systemic inflammation are associated with comorbidities in COPDThe levels of SUV39H1 are significantly reduced in COPD patients with high comorbidities. The levels of SUV39H1 protein expression in PBMCs from normal control (n = 13) and COPD subjects (L-Com: ≤ 1 comorbidity, n = 15 vs. H-Com: ≥ 2 comorbidities, n = 15) were measured by immunoblotting. The protein intensity values for SUV39H1 were normalized to the actin value and are expressed as the fold change over the control value. **p < 0.01Back to article page
