The results of correlation showed that total β-catenin protein and the MnSOD enzyme activity were significantly correlated in PBMCs of healthy subjects (Figure 5a; r = 0.446, p = 0.004), while they were not significantly correlated in CAD patients (Figure 5a; r = 0.019; p = 0.91). This evidence concerns the gene SOD2 and coronary artery disorder.
