carboxylase/necrosis

Tumour necrosis factor (TNF) inhibits the accumulation of acetyl CoA carboxylase (ACC) mRNA by decreasing the rate of ACC gene transcription. The ACC mRNA species found in 30A5 cells are generated from promoter II and TNF inhibits the accumulation of class 2 type mRNAs. By using 5' deletion mutants

Acetyl coenzyme A (acetyl-CoA) carboxylase activity, amount, and mRNA levels increase during the differentiation of 30A-5 preadipocytes to adipocytes. Tumor necrosis factor (TNF) completely prevents this differentiation, with concomitant inhibition of acetyl-CoA carboxylase mRNA accumulation. To

Tumor necrosis factor (TNF) is secreted by macrophages in response to various stimuli and blocks lipid accumulation during the conversion of preadipocytes to adipocytes in culture. In the present report, we investigate the effect of recombinant TNF on the expression of acetyl-coenzyme-A (CoA)

To understand the effects of bcl-2 on glucose metabolism and tumor necrosis factor-alpha (TNF-alpha) mediated cytotoxicity, the activities of glycolytic enzymes (hexokinase, 6-phosphofructo-1-kinase, and pyruvate kinase), lactate dehydrogenase, pyruvate carboxylase, and phosphoenolpyruvate

Diabetic foot represents one of the most common complications in patients with a long standing disease. The etiology is neuropathy, infections and ischemia that together contribute to the sequence of tissue necrosis, ulceration and gangrene. Since treatment is very difficult, we must look for

Multiple cytokines stimulate hepatic lipogenesis in rodents. We have previously shown that lipogenic cytokines can be divided into 2 classes by their mechanism of action and their synergistic interactions. We now report the effects of interleukin 4, a cytokine known to inhibit the synthesis and

We have previously shown that bolus intravenous administration of tumor necrosis factor (TNF) to normal rats results in a rapid (within 90 min) stimulation of hepatic fatty acid synthesis, which is sustained for 17 hr. We now demonstrate that TNF stimulates fatty acid synthesis by several

Tumor necrosis factor-alpha (TNF-alpha) stimulates hepatic lipogenesis. Therefore, it could play a role in the control of ketogenesis. To test this hypothesis, we measured simultaneously free fatty acids (FFA; [1-13C]palmitate) and ketone body (KB; [3,4-13C2]acetoacetate) kinetics, before and after

Tumor necrosis factor/cachectin (TNF) inhibits differentiation of 30A5 preadipocytes into adipocytes. In this process, TNF inhibits the expression of the gene for acetyl-coenzyme-A carboxylase, the rate-limiting enzyme for biogenesis of long chain fatty acids. One of the early reactions caused by

Previous studies demonstrated that administration of tumor necrosis factor (TNF) to diabetic rats rapidly increases serum triglyceride levels and stimulates hepatic lipogenesis without affecting the activity of adipose tissue lipoprotein lipase or serum insulin levels. The purpose of this study was

Intravenous administration of a single dose (100 micrograms/kg bw) of recombinant tumour necrosis factor-alpha (TNF, cachectin) to rats increased the rate of in vitro fatty acid synthesis in interscapular brown adipose tissue (IBAT) from both glucose and alanine, without changes in the oxidation of

The acetyl-CoA carboxylase (ACC) gene contains two distinct promoters, denoted PI and PII. PI is responsible for the generation of class I ACC mRNAs which are induced in a tissue-specific manner under lipogenic conditions. PII generates class II ACC mRNAs which are expressed constitutively. During

Tumor necrosis factor α (TNFα) is a cytokine involved in many metabolic responses in both normal and pathological states. Considering that the effects of TNFα on hepatic gluconeogenesis are inconclusive, we investigated the influence of this cytokine in gluconeogenesis from various glucose

Tumour necrosis factor (TNF)-α induces cardiac metabolic disorder and mitochondrial dysfunction. Hydrogen sulphide (H₂ S) contains anti-inflammatory and biological effects in cardiomyocytes. This study investigated whether H₂ S modulates TNF-α-dysregulated mitochondrial

RNA virus infections are detected by the RIG-I family of receptors, which signal through the adaptor molecule mitochondrial antiviral signaling (MAVS). MAVS then recruits the adaptor's tumor necrosis factor receptor-associated factor (TRAF) 3 and TRAF6, which in turn activate IRF3 and NF-κB,
