Tumor necrosis factor-alpha impairs intestinal phosphate absorption in colitis.

Phosphate homeostasis is critical for many physiological functions. Up to 85% of phosphate is stored in bone and teeth. The remaining 15% is distributed in cells. Phosphate absorption across the brush-border membrane (BBM) of enterocytes occurs mainly via a sodium-dependent pathway, which is mediated by type IIb sodium-phosphate cotransporters (NaPi-IIb). Patients of inflammatory bowel diseases...

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...

Expression 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...

tumor necrosis factor-alpha polymorphism at position -238 in preeclampsia

conclusion: in this study group, tnf-α -238 polymorphism was shown to be different in preeclamptic and non-preeclamptic pregnant women. the aa genotype and the a allele may carry an increased risk for developing of preeclampsia. results: there were significant differences between the two groups in tnf-α genotype at position -238 (p < 0.001). in the preeclamptic group, the frequency of the aa ge...
