Background & Objective:  FLT3-ITD has been recently used as a molecular prognostic marker for risk classification in acute myeloid leukemia (AML) therapy. In this study we aimed to investigate the association of FLT3-ITD gene mutation with bone marrow blast cell count, CD34 ex...

objective(s): mutant forms fms-like tyrosine kinase-3 (flt3), are reported in 25% of childhood acute lymphoid leukemia (all) and 30% of acute myeloid leukemia (aml) patients. in this study, drug response, growth promoting, and protein trafficking of flt3 wild-type was compared with two active mutants (internal tandem duplication (itd)) and d835y. materials and methods:flt3 was expressed on fact...

Background: Sulfur mustard (SM) is a chemical blistering warfare that affects different organs especially hematopoietic system. Prevalence of acute myeloblastic and lymphoblastic leukemia is increased by sulfur mustard exposure. FLT3-ITD mutation can be effective on leukemogenesis. Therefore, the aim of this study was to verify the frequency of FLT3-ITD mutation in the patients who exposed to S...

Background and Objective: Identification of cytogenetic and molecular changes plays an important role in acute myeloid leukemia (AML) patients. Thus, they are used in classification, prognosis and treatment of the disease. The CD123 expression and FLT3 gene mutations are also the variations that may assist in prognosis and treatment of patients with AML.Methods:</...

BACKGROUND FLT3 is mutated in about 1/3 of acute myelogenous leukemia (AML) patients. The aim of the present study was to report the prevalence of FLT3 mutations and comparison with prognostic factors in AML patients in the Northeastern of Iran. MATERIALS AND METHODS This cross-sectional study concerned 100 AML cases diagnosed based on bone marrow aspiration and peripheral blood. DNA for ever...

Analysis of internal tandem duplications of FLT3 (FLT3/ITD) was performed on bone marrow samples obtained at diagnosis and relapse from 108 adult patients with de novo acute myeloid leukemia (AML) to determine the role of this mutation in leukemic relapse. Eighty-three patients had wild-type FLT3 at both diagnosis and relapse, 16 had FLT3/ITD at both stages, whereas 8 had acquired the mutation ...

introduction: about half of acute myeloid leukemia (aml) adult patients have no cytogenetic abnormalities as a main determinant of complete remission after treatment, so other markers are needed such as flt3-itd (fms-like tyrosine kinase3-internal tandem duplication) mutations in patients with normal karyotype. the objective of this study was assessing the frequency of flt3-itd mutations and it...

BACKGROUND Mutations in NPM1 and FLT3 genes represent the most frequent genetic alterations and important diagnostic and prognostic indicators in patients with acute myeloid leukemia (AML). OBJECTIVE We investigated the prevalence and clinical characteristics of NPM1 and FLT3 mutations in 161 patients of de novo AML including adults and children. RESULTS NPM1 mutation was found in 21% and F...

Fms-like tyrosine kinase 3 (FLT3) is one of the most frequently mutated genes in acute myelogenous leukemia (AML) and mutation associated with poor prognosis patients. Two distinct types activating mutations have been identified AML samples. One internal tandem duplications juxtamembrane domain (FLT3-ITD) other point (FLT3-TKD). Gilteritinib a FLT3 inhibitor that inhibits both FLT3-ITD FLT3-TKD...

• Structural aspects of the FLT3 receptor in signalling. Clonal evolution mutants. Recurrent mutations and its regulation signalling cascade drug therapy. Acute myelogenous leukaemia (AML) is an aggressive blood cancer characterized by rapid proliferation immature myeloid blast cells, resulting a high mortality rate. The 5-year overall survival rate for AML patients approximately 25%. Circa 35%...
