Additionally, the degree of phosphorylation expression of leukocyte-induced iNOS was significantly higher in cancer patients compared to non-cancer controls (1.48 ± 0.12 folds, p = 0.0235 by independent t-tests; Kolmogorov–Smirnov test, p > 0.1500) (Fig. 3 and supplementary Figure S2). The gene discussed is NOS2; the disease is cancer.
