Old age (≤65 years), relapsed or refractory disease, and the presence of FMS-like receptor tyrosine kinase-3 (FLT3) internal tandem duplication (ITD) mutation are poor prognostic factors in acute myeloid leukemia (AML). FLT3 inhibitors such as sorafenib have been shown to have a potential role in treating relapsed or refractory AML with FLT3 mutations. In the present report, the use of sorafeni...
BACKGROUND The secondary genetic changes other than the promyelocytic leukemia-retinoic acid receptor (PML-RARA) fusion gene may contribute to the acute promyelocytic leukemogenesis. Chromosomal alterations and mutation of FLT3 (FMS-like tyrosine kinase 3) tyrosine kinase receptor are the frequent genetic alterations in acute myeloid leukemia. However, the prognostic significance of FLT3 mutati...
To generate T cells throughout adult life, the thymus must import hemopoietic progenitors from the bone marrow via the blood. In this study, we establish that thymus settling is selective. Using nonirradiated recipient mice, we found that hemopoietic stem cells were excluded from the thymus, whereas downstream multipotent progenitors (MPP) and common lymphoid progenitors rapidly generated T cel...
AML (Acute myeloid leukemia) is a form of blood cancer where growth of myeloid cells occurs in the bone marrow. The prognosis is poor in general for many reasons. One is the presence of leukaemia-specific recognition markers such as FLT3 (fms-like tyrosine kinase 3). Another name of FLT3 is stem cell tyrosine kinase-1 (STK1), which is known to take part in proliferation, differentiation and apo...
The lack of professional afferent APCs in naive brain parenchyma contributes to the systemic immune ignorance to Ags localized exclusively within the brain. Dendritic cells (DCs) appear within the brain as a consequence of inflammation, but no molecular mechanisms accounting for this influx have been described. In this study we demonstrate that Fms-like tyrosine kinase 3 ligand (Flt3L) recruits...
INTRODUCTION In recent years, Fms-like tyrosine kinase (FLT) 3 has been the subject of several studies as a prognostic marker. OBJECTIVE In this study, the presence of FLT3 mutations in childhood acute leukemias patients and their association with prognosis were investigated. MATERIALS AND METHODS A total of 120 patients, 80 with acute lymphoblastic leukemia (ALL) and 40 with acute myelobla...
Fms-like tyrosine kinase 3-ligand (FL) is a growth factor that may expand dendritic cell and regulatory T cell populations. We hypothesised that FL-induced regulatory T cells would protect mice from experimental rapidly progressive glomerulonephritis. To determine if FL was able to enhance regulatory T cell populations, C57BL/6 mice received 10 days of daily intraperitoneal injections of either...
the development and discovery of new anticancer agents is one of the main goals in medicinal chemistry. the conventional anticancer drugs are concomitant with high incidence of unpleasant side effects like severe gastrointestinal side effects and bone marrow suppression. in recent years, various selective anticancer agents have been emerged like dasatinib. the exact mechanism of dasatinib is th...
Activating mutations of FMS-like tyrosine kinase 3 (FLT3) are present in approximately one third of patients with acute myeloid leukemia (AML) and are associated with adverse prognosis. The important role played by FLT3 in the survival and proliferation of blasts, and its overexpression in most patients with AML, make FLT3 an attractive therapeutic target. We undertook a phase 2 trial of the FL...
