Intestinal trefoil factor induces decay-accelerating factor expression and enhances the protective activities against complement activation in intestinal epithelial cells.
Mucosal damage induces a massive influx of serum complement components into the lumen. The epithelium produces a number of factors that can potentially ameliorate injury including intestinal trefoil factor (ITF), a small protease-resistant peptide produced and secreted onto the mucosal surface by goblet cells, and decay-accelerating factor (DAF), a protein produced by columnar epithelium which ...
متن کاملThe 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 کاملInterleukin-10 up-regulates tumour-necrosis-factor-alpha-related apoptosis-inducing ligand (TRAIL) gene expression in mammary epithelial cells at the involution stage.
Although interleukin-10 (IL-10) is known to contribute to inflammation and pathogenesis in mammalian organs, little is known about its precise role in the mammary gland. We found that IL-10 levels fluctuated during the mouse mammary cycle, showing little expression at the lactation stage and the highest expression at the involution stage. To reveal the effects of IL-10 on involution, expression...
متن کاملIrreversible but not reversible pulpitis is associated with up-regulation of tumour necrosis factor-alpha gene expression in human pulp.
AIM To analyse the gene expression of tumour necrosis factor-alpha (TNF-alpha) in human dental pulps, under normal and inflammatory conditions and to examine the association between any observed alterations in the expression of this cytokine with the severity of the clinical symptoms. METHODOLOGY Eighteen pulpal samples were obtained from single-rooted human teeth. Six of the teeth were norma...
متن کاملTumor necrosis factor alpha-converting enzyme mediates MUC5AC mucin expression in cultured human airway epithelial cells.
Ectodomain shedding of epidermal growth factor receptor (EGFR) ligands [e.g., transforming growth factor type alpha (TGF-alpha)] and EGFR phosphorylation are implicated in mucin production in airway epithelial cells. Tumor necrosis factor alpha-converting enzyme (TACE) is reported to cleave precursor of TGF-alpha, with release of soluble mature TGF-alpha in various epithelial tissues. We hypoth...
