Background and Aims: DNA methyltransferase3A (DNMT3A) is necessary for the adjustment of gene expression, and the mutations in the DNMT3A gene are reported in a variety of leukemia cases. DNMT3A mutations are during cancer progression and cause poor prognosis in many leukemias. Thus, this gene can be a target for new treatments. This study aimed to examine the distribution of DNMT3A mutations i...

introduction: acute myeloid leukemia (aml) is a clonal disease characterized by heterogeneous involvement of hematopoietic bone marrow cell populations. in aml patients, a variety of clinical and biologic parameters, including surface markers, have been examinedfor potential value in predicting treatment response and survival. by checking the myeloid, lymphoid and nonspecific markers on the bla...

BACKGROUND Acute lymphoblastic (ALL) and myeloid leukemia (AML) account for approximately 26% of pediatric cancers. Anthracyclines are widely used to treat these leukemias, but dosing is limited by cardiotoxicity. Data support the efficacy of dexrazoxane as a cardioprotectant in children; however, dexrazoxane use in children is not universally accepted due to concerns about toxicity, impact on ...

PURPOSE To determine the possibility of synergistic antileukemic activity and the underlying molecular mechanisms associated with cytarabine combined with valproic acid (VPA; a histone deacetylase inhibitor and a Food and Drug Administration-licensed drug for treating both children and adults with epilepsy) in pediatric acute myeloid leukemia (AML). EXPERIMENTAL DESIGN The type and extent of ...

UNLABELLED Loss of ephrin receptor (EphB1) expression may associate with aggressive cancer phenotypes; however, the mechanism of action remains unclear. To gain detailed insight into EphB1 function in acute myelogenous leukemia (AML), comprehensive analysis of EphB1 transcriptional regulation was conducted. In AML cells, EphB1 transcript was inversely correlated with EphB1 promoter methylation....

Although standard therapy for AML has been relatively constant over the past 2 decades, this may be changing with enhanced technologies allowing for the classification of acute myeloid leukemia (AML) into molecularly distinct subsets. Some specific subsets of AML have an excellent prognosis in response to standard therapy, whereas the poor prognosis of AML associated with specific sets of mutat...

Background: In the last decade, it has become clear that change of gene expression may alter the hematopoietic cell quiescent state and consequently play a major role in leukemogenesis. WT1 is known to be a player in acute myeloid leukemia (AML) and FOXP3 has a crucial role in regulating the immune response. Objectives: To evaluate the impact of overexpression of WT1and FOXP3 genes on clinical ...

Ratios of immunoproteasome over constitutive proteasome expression are an indicator for sensitivity to bortezomib-containing reinduction chemotherapy in pediatric relapsed acute lymphocytic leukemia and acute myeloid leukemia Manuscript in preparation 8 152 ABSTRACT Bortezomib, a proteasome inhibitor, is in Phase 3 clinical trials for the treatment of pediatric acute myeloid leukemia (AML) and ...

The prognosis of cytogenetically normal acute myeloid leukemia (CN-AML) varies greatly among patients. Achievement of complete remission (CR) after chemotherapy is indispensable for a better prognosis. To develop a gene signature predicting overall survival (OS) in CN-AML, we performed data mining procedure based on whole genome expression data of both blood cancer cell lines and AML patients f...

PURPOSE This study evaluated the prognostic impact of a novel, simple, and standardized assay for monitoring minimal residual disease (MRD) in pediatric acute myelogenous leukemia (AML). EXPERIMENTAL DESIGN The expression of seven leukemia-associated genes (WT1, PRAME, CCL23, GAGED2, MSLN, SPAG6, and ST18) was measured by TaqMan Low Density Arrays in 112 patients and 52 healthy controls.
