Ye et al have reported that the overexpression of MUC1 could increase the superoxide dismutase (SOD) level and catalase (CAT) and glutathione catalase (GSH-Px) activities and decrease the myeloperoxidase (MPO) activity and malondialdehyde (MDA) content in lipopolysaccharide (LPS)-induced ALI cells [16]. The gene discussed is MPO; the disease is acute respiratory distress syndrome.
