Epigenetic regulation of tumor necrosis factor alpha.
Tumor necrosis factor alpha (TNF-alpha) is a potent cytokine which regulates inflammation via the induction of adhesion molecules and chemokine expression. Its expression is known to be regulated in a complex manner with transcription, message turnover, message splicing, translation, and protein cleavage from the cell surface all being independently regulated. This study examined both cell line...
متن کاملRole of tumor necrosis factor alpha in induction of murine CD14 gene expression by lipopolysaccharide.
We previously demonstrated CD14 gene expression in myeloid and epithelial cells of the mouse and showed that expression of the CD14 gene in both is modulated by lipopolysaccharide (LPS). Here we test the hypothesis that the induction of CD14 in these cells is an indirect effect of LPS, one mediated by tumor necrosis factor alpha (TNF-alpha). TNF-alpha induced a transient increase in levels of C...
متن کاملEvaluation 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 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...
متن کاملLipopolysaccharide-inducible and salicylate-sensitive nuclear factor(s) on human tumor necrosis factor alpha promoter.
Lipopolysaccharide (LPS) is one of the most potent trigger substances for monocytes and macrophages causing secretion of tumor necrosis factor alpha (TNF-alpha) and other inflammatory mediators. The nature of the nuclear factors involved in human TNF-alpha gene regulation is still unknown. Nuclear factor kappa B (NF-kappa B) proteins have been suggested to play an important role in gene transcr...
