Moreover, in erythrocytes of non-smoking and smoking AP patients with the GC, CC, and GG genotypes, the total SOD activity was three-fold higher (for non-smokers p = 0.0027, p = 0.0112, and p < 0.0001 and smokers p = 0.0027, p = 0.0045, and p < 0.0001, respectively) than in healthy subjects with corresponding genotypes (Figure S2e,f). This evidence concerns the gene SOD1 and alkaline phosphatase measurement.
