We tested the effect of recombinant human tumor necrosis factor (TNF) on the growth of the murine methylcholanthrene induced fibrosarcoma and the human ovarian carcinoma (NIH:OVCAR-3) in mice. The mice received multiple doses (25-250 micrograms/kg) of TNF starting 7-10 days after s.c. transplantation of tumors when they were easily palpable. TNF was administered i.v. every other day for a total...

Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is an autosomal dominant autoinflammatory disease linked to chromosome 12p13 and, more specifically, with mutations within the tumor necrosis factor receptor superfamily, member 1A gene (TNFRSF1A gene). It is characterized by the presence of fever, abdominal pain, myalgia, arthralgia or arthritis, and skin rash. In this report,...

Tumor necrosis factor alpha (TNF alpha) stimulates production of granulocyte colony-stimulating factor (G-CSF) protein and mRNA in fibroblast cells. In contrast, TNF beta is at least 1,000-fold less potent than TNF alpha in increasing levels of G-CSF and GM-CSF activity and mRNA. The fibroblasts produce G-CSF and GM-CSF mRNA in a coordinate fashion after exposure to TNF. The ability of TNF alph...

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...

With the aim to increase anti-tumor effectiveness of electrochemotherapy, adjuvant immunotherapy with tumor necrosis factor-alpha (TNF-alpha) was tested on tumors in mice. Increased anti-tumor effectiveness on SA-1 tumors was observed after combining TNF-alpha, injected either intratumorally or peritumorally, with electrochemotherapy using suboptimal dose of bleomycin (BLM). The increased anti-...

The infection of tumor necrosis factor (TNF)-deficient mice with low doses of the virulent Mycobacterium avium strain 25291 led to the appearance of necrotic granulomas at 93 days of infection, i.e., sooner than necrotic granulomas appeared in C57BL/6 animals. Additionally, TNF-deficient mice exhibited higher mycobacterial loads in the infected organs, had extremely exacerbated gamma interferon...
