Constitutive expression of the granulocyte-macrophage colony-stimulating factor gene in acute myeloblastic leukemia.
Expression of the granulocyte-macrophage colony-stimulating factor (GM-CSF) gene was studied by Northern blot analysis in normal human hematopoietic cells and a series of leukemias. GM-CSF messenger (m)RNA was detected in activated T cells, but not in normal bone marrow cells, monocytes, or nonactivated T cells. In contrast, leukemic cells from 11 of 22 cases of acute myeloblastic leukemia expr...
متن کاملCharacterization of granulocyte-macrophage colony-stimulating factor receptor on the blast cells of acute myeloblastic leukemia.
Iodinated granulocyte-macrophage colony-stimulating factor (GM-CSF) was used to document the specific binding of GM-CSF to all acute myeloblastic leukemia (AML) samples examined in the present study. There was some heterogeneity in the number of GM-CSF binding sites per cell. To determine whether the low level of binding to some patient samples may be attributed to receptor occupancy by an endo...
متن کاملGranulocyte colony-stimulating factor receptors in human acute myelocytic leukemia.
The binding of granulocyte colony-stimulating factor (G-CSF) to normal and human acute myeloid leukemia (AML) cells was investigated with radiolabeled recombinant human G-CSF (rhG-CSF). In all 14 cases of primary AML specific receptors for G-CSF were demonstrated on purified blast cells. The average numbers of G-CSF receptors ranged from very low to 428 receptors per cell (mean). Normal granulo...
متن کاملGranulocyte colony-stimulating factor receptors on human acute leukemia: biphenotypic leukemic cells possess granulocyte colony-stimulating factor receptors.
Granulocyte colony-stimulating factor (G-CSF) receptors on the gated leukemic blast cells from newly diagnosed patients with acute leukemia or crisis of chronic myelogenous leukemia were investigated using flow cytometric detection. Surface marker analysis and cytochemical studies were conducted simultaneously to characterize the blast cells. Among 24 leukemia cases examined, G-CSF receptor-pos...
متن کاملProduction of Recombinant Human Granulocyte-Colony Stimulating Factor by Pichia pastoris
Human granulocyte-colony stimulating factor (hG-CSF) cDNA was expressed in the methylotrophic yeast Pichia pastoris under the control of the alcohol oxidase (AOX1) promoter. An expression vector for hG-CSF secretion was constructed using vector pPIC9. Higher levels of hG-CSF was obtained using a P. pastoris Mut+ (methanol utilization fast) phenotype. The effects of environmental factors such as...
