Although several cytokines have been demonstrated to be critical regulators of development of multiple blood cell lineages, it remains disputed to what degree they act through instructive or permissive mechanisms. Signaling through the FMS-like tyrosine kinase 3 (FLT3) receptor and the hematopoietin IL-7 receptor alpha (IL-7Ralpha) has been demonstrated to be of critical importance for sustaine...
Objective(s): Cord blood (CB) is known as a valuable source of hematopoietic stem cells (HSC). Identifying strategies that enhance expansion and maintain engraftment and homing capacity of HSCs can improve transplant efficiency. In this study, we examined different culture conditions on ex vivo expansion and homing capacity of CB-HSCs. Materials and Methods: In this study, 4-5 different units o...
AKN-028 is a novel tyrosine kinase inhibitor with preclinical activity in acute myeloid leukemia (AML), presently undergoing investigation in a phase I/II study. It is a potent inhibitor of the FMS-like kinase 3 (FLT3) but shows in vitro activity in a wide range of AML samples. In the present study, we have characterized the effects of AKN-028 on AML cells in more detail. AKN-028 induced a dose...
Preeclampsia is a heterogeneous syndrome affecting 3% to 5% of all pregnancies. An imbalance of the antiangiogenic and proangiogenic factors, soluble receptor fms-like tyrosine kinase 1 and placental growth factor (PGF), is thought to contribute to the pathophysiology of preeclampsia. Maternal plasma PGF and soluble receptor fms-like tyrosine kinase 1 were quantified by specific immunoassays in...
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...
CD103(+) dendritic cells (DCs) in nonlymphoid tissues are specialized in the cross-presentation of cell-associated antigens. However, little is known about the mechanisms that regulate the development of these cells. We show that two populations of CD11c(+)MHCII(+) cells separated on the basis of CD103 and CD11b expression coexist in most nonlymphoid tissues with the exception of the lamina pro...
The c-fms gene encodes the receptor for the macrophage-colony stimulating factor (M-CSF) which promotes the proliferation and survival of cells of the monocytic lineage (1). A cDNA library was constructed from a murine myeloblastic leukemic cell line, BMC-4, in which the c-fms gene was overexpressed (2). Eleven independent full-length cDNAs were isolated after screening with a probe encompassin...
A phosphoinositide kinase specific for the D-3 position of the inositol ring, phosphatidylinositol (PI) 3-kinase, associates with activated receptors for platelet-derived growth factor, insulin, and colony-stimulating factor 1, with products of the oncogenes src, fms, yes, crk, and with polyomavirus middle T antigen. Efficient fibroblast transformation by proteins of the abl and src oncogene fa...
