Circadian dynamics of tumor necrosis factor alpha (cachectin) lethality
Recombinant human tumor necrosis factor-alpha (TNF-alpha) has demonstrable antitumor activity in transplantable murine tumor models and patients with cancer but is highly toxic to both animals and human beings. The narrow therapeutic index of TNF-alpha has limited its anticancer utility. Toxicity associated with many standard anticancer drugs is highly dependent upon the circadian timing of the...
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 کاملTumor necrosis factor alpha/cachectin is a growth factor for thymocytes. Synergistic interactions with other cytokines
Recombinant murine (rm) TNF-alpha but not recombinant human (rh) TNF-alpha induces the proliferation of murine thymocytes in the presence of a comitogenic stimulus. This effect does not appear to be due to the production of significant levels of IL-1, IL-2, or IL-4. although not directly mitogenic (i.e., in the absence of PHA-P) for thymocytes, rmTNF-alpha amplifies the direct mitogenic signals...
متن کاملRaised serum levels of cachectin/tumor necrosis factor alpha in renal allograft rejection
A sensitive radioimmunoassay was used for monitoring serum levels of endogenous cachectin/tumor necrosis factor alpha (TNF) in 10 renal transplant recipients. Acute allograft rejections were associated with marked elevations of circulating TNF. The peak levels of TNF (median 140 pg/ml) were in the same concentration range as previously reported in parasitic infections. The results show that the...
متن کاملTumor necrosis factor/cachectin decreases catalase activity of rat liver.
Tumor bearing hosts and animals treated with endotoxin commonly show a decrease in the catalase activity of the liver and kidney. Since tumor necrosis factor (TNF)/cachectin may play a significant role in these conditions, we investigated its effects on the catalatic and peroxidatic activity of catalase in the liver and kidney of the rat. The activities of glucose-6-phosphate dehydrogenase and ...
