As seen in Figure 7 A–D, the expression of Mn superoxide dismutase [SOD; 79.0 a.u. (65.8–88.4) versus 85.7 a.u. (76.8–92.4); P = 0.383], Cu/Zn SOD [77.0 a.u. (63.0–94.6) versus 92.0 a.u. (75.4–116.0); P = 0.318] and catalase [149.0 a.u. (82.3–356.3) versus 102.0 a.u. (90.7–482.4); P = 0.902] was similar in myoblasts derived from healthy individuals and COPD patients. This evidence concerns the gene SOD1 and chronic obstructive pulmonary disease.
