ALOX5 is implicated in chronic myeloid leukemia development in mouse leukemic stem cells, but its importance in human chronic myeloid leukemia is unknown. Functional ALOX5 was assessed using an LTB4 ELISA and ALOX5, and LTB4R1 mRNA expression was determined via a TaqMan gene expression assay. LTB4R1 and 5-LOX protein levels were assessed by cell surface flow cytometry analysis. At diagnosis ALO...

Myeloid sarcoma is an extramedullary tumor of malignant myeloid cells often associated with acute myeloid leukemia, chronic myeloproliferative disorders and myelodysplastic syndromes. The skin is one of the most commonly affected sites. We report a rare case of cutaneous myeloid sarcoma associated with chronic myeloid leukemia.

Myeloid/lymphoid neoplasms with FGFR1 rearrangement (MLN-FGFR1) comprise a heterogeneous group of that can present as myeloproliferative neoplasm, myelodysplastic/myeloproliferative acute myeloid leukemia, T or B lymphoblastic leukemia/lymphoma, mixed phenotype leukemia. The overall outcome these is poor, and patients often show cytogenetic evolution gain additional chromosomal abnormalities le...

IFN regulatory factor 8 (IRF8) is a key transcription factor for myeloid cell differentiation and its expression is frequently lost in hematopoietic cells of human myeloid leukemia patients. IRF8-deficient mice exhibit uncontrolled clonal expansion of undifferentiated myeloid cells that can progress to a fatal blast crisis, thereby resembling human chronic myelogeneous leukemia (CML). Therefore...

This study shows for the first time that 1,25-dihydroxyvitamin D3[1,25-(OH)2D3] and two fluorinated analogues of 1,25-(OH)2D3 [24,24-F2-1,25-(OH)2D3 and 26, 26, 26, 27, 27, 27-F6-1,25-(OH)2D3] induce macrophage differentiation of human normal and leukemic myeloid stem cells. The addition of either 1,25-(OH)2D3 or one of the two fluorinated analogues of 1,25-(OH)2D3 at concentrations as low as 1...

Chronic lymphocytic leukemia (CLL) is the most common leukemia of adults in the western world and constitutes about 33% of all leukemia's. The incidence of CLL increases with age and are more common in older population. Chronic myeloid leukemia (CML) on the contrary occurs in both young adults and elderly and is a chronic myeloproliferative disease that originates from abnormal pluripotent stem...

Induced pluripotent stem cells (iPSCs) can be generated from various differentiated cell types by the expression of a set of defined transcription factors. So far, iPSCs have been generated from primary cells, but it is unclear whether human cancer cell lines can be reprogrammed. Here we describe the generation and characterization of iPSCs derived from human chronic myeloid leukemia cells. We ...
