Evaluation of Tumor Necrosis Factor Alpha Polymorphism Frequencies in Endometriosis
Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...
متن کاملThe paradoxical effect of tumor necrosis factor alpha (TNF-alpha) in endotoxin-induced uveitis.
PURPOSE To investigate the role of TNF-alpha in endotoxin-induced uveitis (EIU) in mice. METHODS To neutralize TNF-alpha activity, mice were pretreated with either repeated injections of this cytokine or a single injection of antibody against it. The mice were then injected intraperitoneally with 500 micrograms endotoxin, to induce lethal septic shock, or into the footpad with 200 micrograms ...
متن کاملSphingosine synergistically stimulates tumor necrosis factor alpha- induced prostaglandin E2 production in human fibroblasts
Sphingosine is a biologically active derivative of sphingomyelin. It affects diverse cellular functions and its mechanism(s) of action is poorly defined. Tumor necrosis factor alpha (TNF alpha) has recently been shown to rapidly induce sphingomyelin turnover, implicating this metabolic pathway in TNF alpha signal transduction. Because TNF alpha is known to induce prostaglandin E2 (PGE2) product...
متن کاملTumor Necrosis Factor- –Induced Apoptosis in Murine Cytomegalovirus Retinitis
METHODS. The left eyes of nonimmunosuppressed (non-IS) BALB/c mice, immunosuppressed (IS) BALB/c mice, TNFR1 / C57BL/6 mice, and wild-type C57BL/6 mice were inoculated with MCMV k181 by way of the supraciliary route. On postinoculation days 3, 7, and 10, injected eyes of non-IS control and IS experimental mice were removed for RT-PCR for TNFand TNFR1. Protein expression of TNF, caspase-8, and c...
متن کاملExpression of tumor necrosis factor-alpha--converting enzyme and tumor necrosis factor-alpha in human myocarditis.
OBJECTIVES We determined whether tumor necrosis factor-alpha-converting enzyme (TACE) is expressed with tumor necrosis factor-alpha (TNF-alpha) in myocarditis. BACKGROUND Tumor necrosis factor-alpha-converting enzyme, which has recently been identified as belonging to the family of metalloproteinase disintegrin proteins, is responsible for the conversion of TNF-alpha precursor to its mature f...
