AIM To assess the expression level of fms-like tyrosine kinase 3 (FLT3), the incidence of FLT3/internal tandem duplications (ITD) mutation, and prognostic value of FLT3 changes in different types of adult leukemia. METHODS Bone marrow mononuclear cells were isolated from 147 adult patients with leukemia. Reverse transcriptase polymerase chain reaction (PCR) was used to screen FLT3/ITD mutatio...
In the present study, gene expression profiles of acute myeloid leukemia (AML) samples were analyzed to identify feature genes with the capacity to predict the mutation status of FLT3/ITD. Two machine learning models, namely the support vector machine (SVM) and random forest (RF) methods, were used for classification. Four datasets were downloaded from the European Bioinformatics Institute, two...
The FLT3-ITD mutation is one of the most prevalent oncogenic mutations in AML. Several FLT3 kinase inhibitors have shown impressive activity in clinical evaluation, however clinical responses are usually transient and clinical effects are rapidly lost due to drug resistance. One of the resistance mechanisms in the AML refractory patients involves FLT3-ligand induced reactivation of AKT and/or E...
Mutation of the fms-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD), which is one of the most frequent genetic alterations, strongly contributes to an increased risk of treatment failure and to poor prognosis. In this study, we established quantitative fragment analysis of FLT3-ITD simultaneously measuring mutant allele burden and length, verified the analytical performance and ev...
Flt3-internal tandem duplications (Flt3-ITD) is a prevalent mutation in acute myeloid leukemia (AML). We recently reported arsenic trioxide (ATO) and Flt3 inhibition synergize to induce apoptosis in Flt3-ITD cells. However, the signaling effect of ATO in these cells has not been elucidated. Here, we demonstrate that the treatment of ATO potently induces the activation of extracellular regulated...
Constitutive activation of FMS-like tyrosine kinase 3 (FLT3) by internal tandem duplication (ITD) mutations is one of the most common molecular alterations known in acute myeloid leukemia (AML). To investigate the role FLT3/ITD mutations play in the development of leukemia, we generated a FLT3/ITD knock-in mouse model by inserting an ITD mutation into the juxtamembrane domain of murine Flt3. FL...
سابقه و هدف: جهش ژن flt3 (گیرنده تیروزین کینازی شبه) fms باعث تکثیر بدون کنترل سلول های لوسمیک شده و پیش آگهی بدی را به همراه دارد. هدف ما از این مطالعه اجرایی کردن آزمایشات مولکولی برای تشخیص و غربالگری این جهش ها در مبتلایان لوسمی های حاد بود.روش بررسی: در این مطالعه بنیادی، 91 کودک مبتلا به لوسمی های حاد میلوئیدی (aml) و لنفوئیدی (all) از نظر جهش در ژن flt3 شامل وجود جهش itd (internal tandem...
PURPOSE To determine the clinical relevance of mutations in the CCAAT/enhancer binding protein alpha (CEBPA) gene in acute myeloid leukemia (AML) and to examine factors that might modify prognostic impact. PATIENTS AND METHODS The entire CEBPA coding sequence was screened in 1,427 young adult patients with AML, excluding acute promyelocytic leukemia, using denaturing high-performance liquid c...
Acute myeloid leukemia (AML) is a highly heterogeneous disease and internal tandem duplication mutation in FMS-like tyrosine-kinase-3 (FLT3-ITD) has a negative impact on outcome. Finding effective treatment regimens is desperately needed. In this study, we explored the inhibitory effect and mechanism of homoharringtonine (HHT) in combination with ibrutinib on FLT3-ITD mutant AML cells. Conseque...
The MLL-partial tandem duplication (PTD) associates with high-risk cytogenetically normal acute myeloid leukemia (AML). Concurrent presence of FLT3-internal tandem duplication (ITD) is observed in 25% of patients with MLL-PTD AML. However, mice expressing either Mll-PTD or Flt3-ITD do not develop AML, suggesting that 2 mutations are necessary for the AML phenotype. Thus, we generated a mouse ex...
