A cell initiating human acute myeloid leukaemia after transplantation into SCID mice. Lapidot T, Sirard C, Vormoor J, Murdoch B, Hoang T, Caceres-Cortes J et al. Human acute myeloid leukemia is organized as a hierarchy that originates from a primitive hematopoietic cell. Clin Lymph Myel Leuk 2015 15: S104вЂ“S108.Д«onnet D, Dick JE. Relapsed acute myeloid leukemia: need for innovative treatment strategies to improve outcome. This study suggests that CK2 blockade could be a rational approach to minimize the persistence of residual leukemia cells.Дohner H, Weisdorf DJ, Bloomfield CD. Notably, combined CK2 and either NF-ОєB or STAT3 inhibition resulted in a superior cytotoxic effect on leukemia stem cells.

From a molecular standpoint, CK2 blockade was associated with a downmodulation of the stem cell-regulating protein BMI-1 and a marked impairment of AKT, nuclear factor-ОєB (NF-ОєB) and signal transducer and activator of transcription 3 (STAT3) activation, whereas FOXO3a nuclear activity was induced. As a result, leukemia stem cells displayed an increased sensitivity to the chemotherapeutic agent doxorubicin. CK2 inactivation with the selective inhibitor CX-4945 or RNA interference induced an accumulation of leukemia stem cells in the late SвЂ“G2вЂ“M phases of the cell cycle and triggered late-onset apoptosis.

Here, we discovered that the CK2 catalytic О± and regulatory ОІ subunits are consistently expressed in leukemia stem cells isolated from acute myeloid leukemia patients and cell lines. Protein kinase CK2 sustains acute myeloid leukemia cell growth, but its role in leukemia stem cells is largely unknown.
