The effects of GM-CSF and G-CSF in promoting growth of clonogenic cells in acute myeloblastic leukemia.
A small subset of leukemic cells from most patients with acute myeloblastic leukemia (AML) have properties of stem cells and can be assayed by colony formation in agar or methylcellulose. Colony formation generally requires the addition of exogenous growth factors, but the exact factors required are incompletely defined. The AML colony-promoting activities of two recombinant human colony-stimul...
متن کاملStructure and expression of genes of GM-CSF and G-CSF in blast cells from patients with acute myeloblastic leukemia.
The hematopoietic growth factors granulocyte/macrophage colony-stimulating factor (GM-CSF) and G-CSF, available as recombinant products, stimulate the growth in culture of blasts from patients with acute myeloblastic leukemia (AML). We used cDNA probes for each gene to study the genomic organization in blast cells of 22 patients and expression in the blast cells of 18 patients. Alteration in th...
متن کاملMyelodysplasia syndrome and acute myeloid leukemia in patients with congenital neutropenia receiving G-CSF therapy.
Granulocyte colony-stimulating factor (G-CSF) has had a major impact on management of "severe chronic neutropenia," a collective term referring to congenital, idiopathic, or cyclic neutropenia. Almost all patients respond to G-CSF with increased neutrophils, reduced infections, and improved survival. Some responders with congenital neutropenia have developed myelodysplastic syndrome and acute m...
متن کاملG-CSF receptor (CSF3R) mutations in X-linked neutropenia evolving to acute myeloid leukemia or myelodysplasia.
X-linked neutropenia (XLN) is a rare form of Congenital Neutropenia (CN) caused by inherited gain-of-function mutations of WAS. Here we report 2 cases of the original L270P X-linked neutropenia kindred that evolved to MDS or AML, with acquisition of G-CSFR (CSF3R) mutations and monosomy 7. Thus, leukemic transformation with acquisition of CSF3R mutations and monosomy 7 is not restricted to clas...
متن کاملActin filament reorganization in HL-60 leukemia cell line after treatment with G-CSF and GM-CSF.
Currently, information regarding the influence of growth factors on the cytoskeleton, including G-CSF and GMCSF, remains limited. In the present study we show alterations in F-actin distribution and cell cycle progression in HL-60 promyelocytic leukemia cells, resulting from treatment with these cytokines in vitro. We found that both agents caused F-actin reorganization. Although multiple poten...
