CBY1 and chronic myelogenous leukemia, BCR-ABL1 positive: Bone marrow MCF of the majority of CML-CP patients (30/40) included in our study exhibited a reduction of Cby1 protein below 50% of the reference value (corresponding to the WB signal intensity of equal amounts of proteins from HP peripheral blood pooled to avoid individual differences) with a median value of 0.278 (Figure 2A-left panel and Table S2).
