Regulation of the Egr-1 gene by tumor necrosis factor and interferons in primary human fibroblasts.
Treatment of quiescent primary human fibroblasts with tumor necrosis factor (TNF) alpha, TNF-beta, interleukin-1, interferon (IFN) alpha, IFN beta, or IFN gamma induced Egr-1 mRNA. In primary human fibroblasts TNF-alpha and TNF-beta were mildly mitogenic and IFN alpha and IFN gamma were growth inhibitory. However, in HeLa cells TNF but not IFN induced the expression of Egr-1 mRNA, while both cy...
متن کاملThe tumor necrosis factor receptor and human neutrophil function. Deactivation and cross-deactivation of tumor necrosis factor-induced neutrophil responses by receptor down-regulation.
Despite numerous reports, the role of tumor necrosis factor (TNF) in polymorphonuclear leukocyte (PMN) function remains controversial. We found TNF to be a potent, pertussis toxin-independent stimulator of PMN adhesion (ED50 2.6 pM). TNF-stimulated PMN under adherent conditions released up to 65% of their transcobalamine content (ED50 3.9 pM) and increased their burst activity 10-fold (ED50 3.2...
متن کاملTumor necrosis factor receptor 1 functions as a tumor suppressor.
Tumor necrosis factor (TNF) is a key player in inflammatory bowel disease and has been variably associated with carcinogenesis, but details of the cross talk between inflammatory and tumorigenic pathways remain incompletely understood. It has been shown that, in C57BL/6 mice, signaling via TNF receptor 1 (TNFR1) is protective from injury and inflammation in experimental colitis. Therefore, we h...
متن کاملAbnormal insulin-receptor down regulation and dissociation of down regulation from insulin biological action in cultured human tumor cells.
The sensitivity of insulin receptors to down regulation by insulin has been measured in cultured human tumor cells (breast tumor cell lines MCF-7, T-47D, and colon tumor cell line HCT-8). Insulin receptors on breast tumor cells were resistant to down regulation (15-17% maximum loss of insulin binding after 4 h exposure to 170 nM insulin). HCT-8 cells were sensitive to down regulation after 4 h ...
متن کاملAssociation of VNTR polymorphism of tumor necrosis factor receptor 2 (TNFRSF1B) with pulmonary tuberculosis
This study was designed to find out the impact of the variable number of tandem repeats (VNTR) of the tumor necrosis factor receptor 2 (TNFRSF1B) on pulmonary tuberculosis (PTB) risk in an Iranian population. This case-control study was done on 159 PTB patients and 158 healthy subjects. Bi-allelic TNFRSF1B VNTR was genotyped by polymerase chain reaction. Logistic regression analysis revealed no...
