When comparing healthy individuals against CML patients, PTPRG protein expression levels were significantly higher on neutrophils (U = 30, p < 0.002) and monocytes (U = 24, p < 0.007) amongst healthy individuals in comparison to CML patients at diagnosis (Fig. 3d). This evidence concerns the gene PTPRG and chronic myelogenous leukemia, BCR-ABL1 positive.
