OBJECTIVES Constitutive activation of the fms-like tyrosine kinase 3 (FLT3) receptor by internal tandem duplication (ITD) of the juxtamembrane region has been described in patients with acute myeloid leukemia. FLT3/ITDs are present in about 20-30% of all acute myeloid leukemia cases. It has been shown that the mutation is correlated with worse prognosis. However, none of the previous studies in...
Effects of concurrent inhibition of mTORC1/2 and Bcl-2/Bcl-xL in human acute myeloid leukemia cells were examined. Tetracycline-inducible Bcl-2/Bcl-xL dual knockdown markedly sensitized acute myeloid leukemia cells to the dual TORC1/2 inhibitor INK128 in vitro as well as in vivo. Moreover, INK128 co-administered with the Bcl-2/xL antagonist ABT-737 sharply induced cell death in multiple acute m...
Acute myeloid leukemia with t(6;9)(p22;q34) is listed as a distinct entity in the 2008 World Health Organization classification, but little is known about the clinical implications of t(6;9)-positive myeloid leukemia in children. This international multicenter study presents the clinical and genetic characteristics of 62 pediatric patients with t(6;9)/DEK-NUP214-rearranged myeloid leukemia; 54 ...
BACKGROUND Tyrosine kinase inhibitors, such as imatinib, are not considered curative for chronic myeloid leukemia--regardless of the significant reduction of disease burden during treatment--since they do not affect the leukemic stem cells. However, the stochastic nature of hematopoiesis and recent clinical observations suggest that this view must be revisited. DESIGN AND METHODS We studied t...
We examined the gene expression profiles of two independent cohorts of patients with acute myeloid leukemia [n=247 and n=214 (younger than or equal to 60 years)] to study the applicability of gene expression profiling as a single assay in prediction of acute myeloid leukemia-specific molecular subtypes. The favorable cytogenetic acute myeloid leukemia subtypes, i.e., acute myeloid leukemia with...
Adenosine deaminase (ADA) and ecto-5'-nucleotidase (5'-N) activities were examined in peripheral leukocytes from patients with leukemias, including nine patients with chronic myeloid leukemia (CML) in blast crisis. Four of none cases of CML in blast crisis were myeloid and the remaining lymphoid morphologically. The diagnosis of CML in lymphoid blast crisis was further contributed by the measur...
Nano Cell Cycle Checkpoint Inhibitors In article number 2300736, Daishun Ling, Fangyuan Li, and co-workers demonstrate that ultra-small iron oxide nanoparticles (IONPs) can serve as a selective nano cell cycle checkpoint inhibitor (NCCI) to catalyze the intracellular H2O2 into abundant ·OH, cleave heat shock protein 90 (Hsp90), thus induce degradation of client ATR/CHK1, leading dysfunction G2/...
Cathepsin G (CG) is a serine protease normally found within the azurophil granules of neutrophils. CG is expressed during the early stages of normal myeloid differentiation and-aberrantly-by myeloid leukemia cells. We have recently identified CG-derived HLA-A*0201-binding peptides that constitute promising targets for the immunotherapy of myeloid leukemia.
Cyclic adenosine monophosphate response-element binding protein (CREB) is a nuclear protein that regulates expression of genes that control cell proliferation, differentiation, and survival. To analyze CREB expression in leukemia cells, we conducted Western blot analysis of bone marrow cells obtained from patients with acute lymphoblastic leukemia, patients with acute myeloid leukemia, and pati...
To characterize the biology and optimal therapy of acute mixed-lineage leukemia in children, we reviewed the pathologic and clinical features, including response to therapy, of 35 patients with mixedlineage leukemia. The majority of cases (91%) had blasts cells that simultaneously expressed either T-lineage plus myeloid markers (T/myeloid, n 20) or B-lineage plus myeloid markers (B/myeloid, n 1...
