Tumor necrosis factor alpha (TNF-alpha) has been shown to both stimulate and inhibit the proliferation of hematopoietic progenitor cells (HPCs) in vitro, but its mechanisms of action are not known. We demonstrate that the direct effects of TNF-alpha on murine bone marrow progenitors are only inhibitory and mediated at least in part through downmodulation of colony-stimulating factor receptor (C...

The protein glycosylation inhibitor tunicamycin protected male BALB/c mice from tumor necrosis factor alpha-induced liver failure. Tunicamycin also inhibited tumor necrosis factor-induced cell death in primary hepatocyte cultures with a median inhibitory concentration of 8 nM, but not in the tumor cell line WEHI 164 clone 13. Hepatocyte death in our culture system was characterized by DNA fragm...

Background: Tumor necrosis factor alpha is a proinflammatory cytokine and  as  polyvalent initial response of inflammatory cells which facilitated through the creation of coronary atherosclerosis . It also seems that the polymorphism and susceptibility to atherosclerosis is related to TNF-α gene promoter. The purpose of this study was to investigate single nucleotide polymorphis...

background: there is no convenient cheap pragmatic experimental model for nonalcoholic fatty liver disease (nafld)/nonalcoholic steatohepatitis (nash). we aimed to create a pragmatic model of nafld/nash. methods: sprague-dawley rats were fed a high-fat, high sugar homemade diet ad libitum for seven weeks. the high-fat, high sugar diet included 59% of energy derived from fat, 30% from carbohydra...

We report that tumor necrosis factor (TNF) alpha induced a strong antitumor immune reaction when it was produced in arteries leading to tumors by gene transfer in vivo. We used a mouse model carrying a sarcoma-180 tumor in the right footpad and injected the fusogenic liposomes encapsulating the human TNF-alpha gene into the right femoral artery. Under this condition, human TNF-alpha was detecte...

Tumor necrosis factor alpha (TNF-α) expression amplifies to excess amounts in several disorders such as rheumatoid arthritis and psoriasis. Although, Anti-TNF biologics have revolutionized the treatment of these autoimmune diseases, formation of anti-drug antibodies (ADA) has dramatically affected their use. The next generation antibodies (e.g. Fab, scFv) have not only reduced resulted immunoge...

Objective: This study aimed to monitor oxidative stress parameters including total antioxidant status (TAS) and oxidant (TOS), tumor necrosis factor-alpha (TNF-α) level during the healing process in hair goats with metritis. 
 Materials Methods: was carried out on a of 25 metritis (n=10; Group 1) healthy (n=15; 2). The beginning accepted as day 0. In both 1 2, blood samples were collected ...

The effects of fibroblast growth factor basic (bFGF), transforming growth factor alpha (TGF alpha), recombinant human epidermal growth factor (EGF), recombinant human tumor necrosis factor alpha (TNF alpha), and recombinant interleukin 1 alpha (IL-1 alpha) on lymphatic angiogenesis were assessed in cultured newborn bovine lymphatic endothelial cells (NBLEC). bFGF, TGF alpha, and EGF stimulated ...

objective(s): acquisition of tnf-α resistance plays role in the onset and growth of malignant tumors. previous studies have demonstrated that mcf-7 cell line and its doxorubicin resistant variant mcf-7/adr are resistant against the cytotoxic effects of tnf-α. in this study, we investigated the role of akt activation in resistance of mcf-7 and mcf-7/adr against tnf-α cytotoxicity. materials and ...

cytokines play a part in pathogenesis of periodontitis via inflammation phenomenon. aggressive periodontitis (agp) is a multifactorial disease resulting in rapid tooth loss due to severe destruction of tooth supporting apparatus. recently, researchers have focused on genetic susceptibility of periodontitis through investigating the gene variations of cytokines and other components of immune res...
