purpose: in order to express human granulocyte-macrophage colony stimulating factor (hgm-csf) under heat shock. materials and methods: two expression plasmids were constructed based on pbc(sk) plasmid. the expression cassettes in the two plasmids are equipped with a 75 base pair fragment, derived from the pl promoter of the bacteriophage lambda (λ). the plasmids also contain a temperature muta...
The interferon-inducible (Ifi)204 gene was isolated as a macrophage-colony stimulating factor (M-CSF)-responsive gene using a gene trap approach in the myeloid interleukin-3 (IL-3)-dependent FD-Fms cell line, which differentiates in macrophages in response to M-CSF. Here, we show that Ifi204 was transcriptionally activated in response to M-CSF, and FD-Fms cells decreased their growth and commit...
Three cases of acute myeloblastic leukemia (AML) were identified in which clonogenic cells proliferated autonomously in vitro. Cells from two of these cases were found to secrete a colony-stimulating factor (CSF) that was immunologically and molecularly related to GM-CSF. Growth of AML-CFU could be blocked by the addition of a neutralizing antiserum to GM-CSF. Northern blot hybridization of leu...
To explore efficient of different gene transfer methods and to express human granulocyte-macrophage colony-stimulating factor (hGM-CSF) in silk glands of transgenic silkworm, a novel transgenic vector containing a hGM-CSF controlled by silkworm fibroin heavy chain gene promoter (Pfib-H) with a neomycin resistance gene (neo) driven by BmNPV (B. mori nucleopolyhedrovirus) immediate-early gene ie-...
PURPOSE Colorectal cancer infiltration by CD16(+) myeloid cells correlates with improved prognosis. We addressed mechanistic clues and gene and protein expression of cytokines potentially associated with macrophage polarization. EXPERIMENTAL DESIGN GM-CSF or M-CSF-stimulated peripheral blood CD14(+) cells from healthy donors were cocultured with colorectal cancer cells. Tumor cell proliferati...
Macrophage colony-stimulating factor (M-CSF) is a multifunctional cytokine attributed with key biological functions beyond the first discovered role in promoting proliferation of myeloid cell lineage. The human pancreatic cancer cell line MIA PaCa-2, from which the M-CSF gene was originally cloned, was used to study regulation of M-CSF expression. Expression of M-CSF was inducible by interleuki...
Background and purpose: Early and accurate diagnosis of bacterial meningitis is critical concern. Optimum and rapid laboratory facilities are not routinely available for detecting the etiologic agents of meningitis. The objective of this study was the comparison of polymerase chain reaction (PCR) assay with culture, for the detection of bacteria in CSF samples from patients suspected of menin...
We have investigated the T cell populations in the cerebrospinal fluid (CSF) of chronic progressive multiple sclerosis (MS) patients. Individual T cells from the CSF and blood were cloned before expansion and their clonotypes were defined by analysis of rearranged T cell receptor beta chain and gamma chain genes. 87 T cell clones from blood and CSF of two patients with chronic progressive MS we...
Expression of the granulocyte-macrophage colony-stimulating factor (GM-CSF) gene in acute myelocytic leukemia (AML) was assayed by Northern blot analysis. GM-CSF messenger RNA (mRNA) was detected in the freshly obtained mononuclear cells of only one of 48 cases of AML, in contrast with recent reports that GM-CSF mRNA might be detected in half of the cases of AML when RNA is prepared from T-cell...
