title: Constitutive phosphorylation of FKHR transcription factor as a prognostic variable in acute myeloid leukemia.
abstract: The transcription factor FKHR, which is controlled by Akt-PKB signaling, is involved in regulating cell cycle progression and cell death. In this study, the phosphorylation of FKHR was observed in 45 (73.8%) of 61 patients with acute myeloid leukemia (AML). The phosphorylation of Akt-PKB was found to be significantly associated with phospho-FKHR (P<0.001). Patients with phospho-FKHR had a significantly shorter overall survival than those without (P<0.05). In conclusion, the constitutive phosphorylation of FKHR was observed in the majority of AML, and the detection of phospho-FKHR might provide a new tool for identifying AML patients with an unfavorable outcome.
