Decreased macrophage colony-stimulating factor mRNA expression from activated cord versus adult mononuclear cells: altered posttranscriptional stability.
We have previously shown that protein production and mRNA expression of granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF), and interleukin-3 are decreased in stimulated mononuclear cells (MNCs) from human umbilical cord compared with adult peripheral blood. These deficiencies may contribute to the increased susceptibility of neonates to inf...
متن کاملIncreased Granulocyte-Macrophage Colony-Stimulating Factor mRNA Instability in Cord Versus Adult Mononuclear Cells Is Translation- Dependent and Associated With Increased Levels
The level of granulocyte-macrophage colony-stimulating factor (GM-CSF) mRNA is fourfold lower in phorbol myristate acetate (PMA) + phytohemagglutinin (PHA)-activated mononuclear cells (MNC) from newborns compared with adults. The GM-CSF transcription rate is similar in umbilical cord and adult MNC, but transcript half-life is threefold lower in cord activated MNC. Interaction of RNA binding pro...

متن کاملRegulation of interleukin-11 protein and mRNA expression in neonatal and adult fibroblasts and endothelial cells.
Interleukin-11 (IL-11), a newly-identified cytokine produced by stromal cells, elevates platelet counts in neonatal rats in vivo and synergizes in vitro with IL-3 in supporting murine megakaryocyte colony formation and stimulating hematopoietic stem cells. Megakaryocytopoiesis is also enhanced by other colony-stimulating factors (CSFs), including IL-3, IL-6, and Steel factor (SLF). Dysregulatio...
متن کاملShift from posttranscriptional to predominant transcriptional control of the expression of the GM-CSF gene during activation of human Jurkat cells.
The expression of the granulocyte-macrophage colony-stimulating factor (GM-CSF) gene is differentially regulated in various cell types. We investigated the mechanisms controlling its expression in 12-O-tetradecanoylphorbol-13-acetate plus phytohemagglutinin-stimulated Jurkat cells, a human T-cell line. In unstimulated cells, GM-CSF mRNA was undetectable by Northern blot. Upon activation, it was...
