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 کاملTumor necrosis factor mediates endotoxic effects in mice.
Endotoxic reactions induced in mice by recombinant human tumor necrosis factor (TNF) were examined. Mice showed a dose-dependent hypothermia after intravenous TNF injection which was similar to a reaction to lipopolysaccharide injection. Plasma glucose levels were decreased, and plasma lactate levels were increased. Blood hematocrit levels were increased after TNF injection. No interleukin-1 ac...
متن کاملTumor necrosis factor and anti-tumor necrosis factor therapies.
Tumor necrosis factor (TNF) plays a crucial role in the pathogenesis of immune-mediated inflammatory diseases (IMID). As a result, the inhibition of TNF is an important therapeutic avenue in the treatment of these pathophysiologically diverse disease states. This section discusses TNF, its receptors, and its role in immunoregulation and inflammation, as well as the currently available anti-TNF-...
متن کاملTumor Necrosis Factor α Regulatesα vβ5 Integrin Expression by Osteoclast Precursors in Vitro and in Vivo1.
Early osteoclast precursors, in the form of murine bone marrow macrophages (BMMs), while expressing no detectable avb3 integrin, contain abundant avb5 and attach to matrix in an av integrin-dependent manner. Furthermore, avb5 expression by osteoclast precursors progressively falls as they assume the resorptive phenotype. We find the osteoclastogenic agent, tumor necrosis factor-a, (TNF) down-re...
متن کاملTumor necrosis factor receptor-associated factor 2 mediates mitochondrial autophagy.
BACKGROUND Tumor necrosis factor (TNF) signaling protects against ischemia/reperfusion-induced cardiomyocyte death, in vitro, ex vivo, and in vivo. TNF-receptor-associated factor 2 (TRAF2), an E3 ubiquitin ligase, coordinates cytoprotective signaling downstream of both TNF receptors, via unclear mechanisms. Noting that TRAF2 is recruited to mitochondria, and that autophagic removal of ubiquitin...
