Results Analysis of the expression of proteins of JAK2 in leukemic blasts, there was no detectable constitutive expression of phosphorylated JAK2 in all the AML samples analyzed; Furthermore, we could detect a constitutive activation of STAT 3 by immunoprecipitation of the targeted protein in primary leukemic blasts from 3 of 11 AML patients without any cytokine treatment; Pretreatment clinical characteristics, and treatment regimens did not differ significantly between patients with and without constitutive STAT3 activity, there was not significant relation between the constitutive activation of STAT3 and the FAB subvariety and chromosome karyotype; However, the 3 patients with constitutive STAT3 activity seemed to have adverse treatment outcome, one did not show remission, the other two patients relapsed shortly after remission; Consistent with the above-mentioned result, leukemic blasts from the 3 samples with constitutive expression of STAT3 showed higher percentage of spontaneous apoptosis and S-phase cells.
