STAT3 and alkaline phosphatase measurement: A previous study demonstrated that compared to CML patients in chronic phase (CML-CP), the expression of STAT3 in the bone marrow samples of CML patients in accelerated phase/blast phase (CML-AP/BP) was significantly elevated; additionally, the level of STAT3 expression in IM-R K562/G01 cells was significantly higher than that in K562 cells (33).
