As can be seen in Figure 8A, as compared to the expression found in normal blood, CP-CML, and ALL, the expression of CD25 was found to be increased in BC-CML (percentage of CD25/ABL1 = 19.3 in CP-CML and 75 in BC-CML). This evidence concerns the gene IL2RA and chronic myelogenous leukemia, BCR-ABL1 positive.
