Basal NQO1 activity, NQO1, HMOX1, SOD1 and TXNRD1 mRNA expression in alveolar macrophages from S and COPD patients. Alveolar macrophages were isolated from S and COPD patients. Basal levels of NQO1 activity were assessed by NQO1 activity enzyme assay (A) (n = 8 S and n = 8 COPD). Basal mRNA expression of NQO1 (n = 8 S and n = 8 COPD), HMOX1 (n = 8 S and n = 8 COPD), SOD1 (n = 6 S and n = 8 COPD) and TXNRD1 (n = 6 S and n = 8 COPD) was assessed by RT-qPCR relative to endogenous control (2−ΔCt) (B–E respectively). Data represent individual patients with mean. * = significant difference between groups (p < 0.05)
