The Effect of Aerobic Training on Tumor Necrosis Factor alpha, Hypoxia-Inducible Factor-1 alpha & Vascular Endothelial Growth Factor Gene Expression in Cardiac Tissue of Diabetic Rats
Objective: The goal of this research was to determine the influence of 4 weeks aerobic training on gene expression of tumor necrosis factor alpha (TNF-α), hypoxia-inducible factor-1 alpha (HIF-1α) and vascular endothelial growth factor (VEGF) in the cardiac tissue of diabetic rats. Materials and Methods: In an experimental study, 30 male wistar rats were partitioned into three groups (n=10), d...
متن کاملMechanisms of tumor necrosis factor-granulocyte-macrophage colony-stimulating factor-induced dendritic cell development.
In a previous report, we described that tumor necrosis factor (TNF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) synergistically enhanced the development of dendritic cell (DC) progeny from early stem cells and that there is a common monocyte-DC progenitor cell. Low levels of DC were obtained with GM-CSF alone, and TNF by itself failed to induce stem cell development. Here, we ...
متن کاملMetaxin is required for tumor necrosis factor-induced cell death.
We used retrovirus insertion-mediated random mutagenesis and tumor necrosis factor (TNF) selection to generate TNF-resistant lines from L929 cells. The metaxin gene, which encodes a protein located on the outer membrane of mitochondria, was identified to be the gene disrupted in one of the resistant lines. The requirement of metaxin in TNF-induced cell death of L929 was confirmed by the restora...
متن کاملModulation of colony-stimulating factor-1 receptors on macrophages by tumor necrosis factor.
The effect of murine rTNF-alpha on the binding of human 125I-rCSF-1 to murine thioglycolate-elicited peritoneal exudate macrophages (PEM) was investigated. At 4 degrees C, 125I-CSF-1 binding to PEM was inhibited by preincubation with human rCSF-1, but not by other cytokines. When PEM were incubated with various cytokines at 37 degrees C, murine rTNF-alpha caused greater than 90% decrease in 125...
متن کاملNF-kappaB1 (p50) is upregulated in lipopolysaccharide tolerance and can block tumor necrosis factor gene expression.
Monocytes respond to lipopolysaccharide (LPS) stimulation with a rapid expression of the tumor necrosis factor (TNF) gene. Upon repeated LPS stimulation there is, however, little production of TNF mRNA and protein; i.e., the cells are tolerant to LPS. Analysis of NF-kappaB proteins in gel shift assays demonstrated that the DNA binding activity that is induced by LPS stimulation in tolerant cell...
