The tumor necrosis factor alpha (TNF-alpha) gene was introduced by retroviral gene transfer into the TNF-alpha-insensitive tumor cell line J558L. Production of 40 pg/ml TNF-alpha by clone J2T12 consistently did not change the growth rate in vitro, but drastically suppressed tumor growth when injected into syngeneic BALB/c mice. Within 2 wk, 90% of the mice inoculated with J558L cells developed ...
The cDNA for one of the receptors for human tumor necrosis factor (TNF) has been isolated. This cDNA encodes a protein of 455 amino acids that is divided into an extracellular domain of 171 residues and a cytoplasmic domain of 221 residues. The extracellular domain has been engineered for expression in mammalian cells, and this recombinant derivative binds TNF alpha with high affinity and inhib...
BACKGROUND Rats subjected to bile duct ligation (BDL) exhibit increased systemic oxidative stress and brain dysfunction characteristic of hepatic encephalopathy (HE), including fatigue, neurotransmitter alterations, cognitive and motor impairment, and brain inflammation. The levels of tumor necrosis factor-alpha (TNF-α) and asymmetric dimethylarginine (ADMA) are both increased in plasma and bra...
Proinflammatory cytokines and their receptors are increased in the peripheral blood of patients with heart failure. We measured cytokines and their receptors in systemic artery (SA), coronary sinus (CS) and infra-renal inferior vena cava (IVC), in order to investigate their origin and influential factors. Thirty patients with idiopathic dilated cardiomyopathy were performed echocardiography at ...
Recent studies have proposed that tumor necrosis factor alpha (TNF-alpha) and ionizing radiation induce apoptosis by activating hydrolysis of sphingomyelin to ceramide. Bcl-2 and a related gene, Bcl-X, inhibit several forms of apoptosis. Herein, we report that internucleosomal DNA fragmentation, characteristic of apoptosis and induced by ionizing radiation, is accompanied by concomitant decreas...
A replication-defective adenoviral vector, Ad.Egr-TNF.11D, was engineered by ligating the CArG (CC(A/T)6GG) elements of the Egr-1 gene promoter upstream to a cDNA encoding human tumor necrosis factor-alpha. We report here that Ad.Egr-TNF.11D is activated by the clinically important anticancer agents cisplatin, cyclophosphamide, doxorubicin, 5-fluorouracil, gemcitabine, and paclitaxel. N-acetylc...
Tumor necrosis factor alpha (TNF alpha) is thought to be a critical mediator of malaria fever, and mild malaria was previously reported to be linked to the MHC region containing the tumor necrosis factor alpha gene (TNF). Thirty-four families from Burkina Faso were analyzed to test for linkage between polymorphisms within the MHC region and mild malaria using the maximum-likelihood-binomial (ML...
