OBJECTIVE
Genetic polymorphisms in tumor necrosis factor-alpha (TNF-alpha) modify the association between polyunsaturated fatty acids (PUFA) and plasma high-density lipoprotein (HDL) cholesterol in a population with type 2 diabetes. The objective of this study was to determine whether this gene x
BACKGROUND
Heterogeneity in circulating lipid concentrations in response to dietary polyunsaturated fatty acids (PUFAs) may be due, in part, to genetic variations. Tumor necrosis factor-alpha (TNF-alpha) is a proinflammatory cytokine that can induce hyperlipidemia and is known to be modulated by
1. Responses to cytokines and other inflammatory stimuli have been shown to be enhanced by fats rich in n-6 polyunsaturated fatty acids and suppressed by fats rich in n-3 polyunsaturated fatty acids and oleic acid or poor in n-6 polyunsaturated fatty acids. 2. Corn oil is rich and coconut oil, olive
In inflammatory reactions there are complex interactions of protein mediators (cytokines) and mediators derived from lipids. An important event in inflammation is superoxide production, in relation to microbicidal activity as well as tissue damage. We have studied interactions of lipid mediators
Cell-associated and secreted tumour necrosis factor (TNF), prostaglandin (PG) E2, and 6-keto PGF1 alpha were monitored at various times following in vitro stimulation of resident peritoneal macrophages with lipopolysaccharide (LPS). Macrophages were obtained from mice maintained on diets containing
OBJECTIVE
Neutrophils and tumor necrosis factor (TNF) play important roles in the pathogenesis of rheumatoid arthritis (RA). Modulation of TNF receptors (TNFRs) may contribute to the regulation of tissue damage, and n-6 polyunsaturated fatty acids (PUFAs) such as arachidonic acid (AA) can increase
The peritoneal macrophages from mice maintained for 16 days on a diet containing (10%) menhaden oil contained less arachidonic acid and more n-3 polyunsaturated fatty acids (n-3 PUFA) than those maintained on diets containing an equivalent amount of corn oil. Following stimulation with
BACKGROUND
Gastric cancer is the second most common cause of cancer-related mortality worldwide. 5-fluorouracil (5-FU) is a commonly used anti-cancer drug. Various polyunsaturated fatty acids (PUFAs) are known to have tumoricidal action both in vitro and in vivo. Though PUFAs are known to augment
Tumor necrosis factor (TNF) is a macrophage derived peptide that has an antitumor action and modulates immune and inflammatory reactions. Dietary fatty acids may modulate TNF production as dietary n-3 polyunsaturated fatty acids suppress human monocyte TNF production, but enhance its secretion by
Tumor necrosis factor (TNF), prostaglandin (PG) E2 and 6-keto-PGF1 alpha production by murine peritoneal macrophages was monitored following in vitro stimulation with lipopolysaccharide. Macrophages were obtained from mice fed diets containing increasing ratios of (n-3) to (n-6) fatty acids by
BACKGROUND
Previous studies did not draw a consistent conclusion about the effects of marine-derived n-3 polyunsaturated fatty acids (PUFAs) on fasting blood level of C-reactive protein (CRP), interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α).

Some neoplastic cell lines are readily killed when incubated in the presence of polyunsaturated fatty acids (PUFA). In an attempt to elucidate this phenomenon, we studied PUFA-driven superoxide (O2-) production by cultured NS-1 cells (murine lymphoid tumor cells). We find: (1) Even in the absence of
Development of exudative skin necrosis in female rats of Vistar line was caused by Selye method (with help of subcutaneons injections of sodium chlorate). The number of rats which got skin necrosis was bigger than when animals were fed on food containing butter or sardine fat, at that in the second
We examined whether the synthesis of interleukin-1 or tumor necrosis factor, two cytokines with potent inflammatory activities, is influenced by dietary supplementation with n-3 fatty acids. Nine healthy volunteers added 18 g of fish-oil concentrate per day to their normal Western diet for six
