1	8197147	Concurrently, TNF-alpha treatment causes a moderate decrease in the insulin-stimulated autophosphorylation of the insulin receptor (IR) and a dramatic decrease in the phosphorylation of IR substrate 1, the major substrate of the IR in vivo.
2	7523453	Since a defective insulin receptor (IR) tyrosine kinase activity has been observed in obesity and NIDDM, we measured the IR tyrosine kinase activity in the Zucker (fa/fa) rat model of obesity and insulin resistance after neutralizing TNF-alpha with a soluble TNF receptor (TNFR)-lgG fusion protein.
3	7926300	Neutralization of TNF-alpha in one of these models improves insulin sensitivity by increasing the activity of the insulin receptor tyrosine kinase, specifically in muscle and fat tissues.
4	7926300	On a cellular level, TNF-alpha is a potent inhibitor of the insulin-stimulated tyrosine phosphorylations on the beta-chain of the insulin receptor and insulin receptor substrate-1, suggesting a defect at or near the tyrosine kinase activity of the insulin receptor.
5	11126235	Analysis of these animals demonstrated that the genetic absence of TNF signaling in obesity: (i) significantly improves insulin receptor signaling capacity and consequently insulin sensitivity; (ii) prevents brown adipose tissue atrophy and beta3-adrenoreceptor deficiency and improves thermo-adaptive responses, (iii) decreases the elevated PAI-1 and TGFbeta production; and (iv) lowers hyperlipidemia and hyperleptinemia.
6	11912559	Because tumor necrosis factor-alpha (TNF-a ) is proinflammatory and may thus inhibit the action of insulin at the endothelial cell level, we have now investigated whether TNF-a affects (1) insulin receptor content; (2) insulin receptor (IR) autophosphorylation induced by insulin, and (3) e-NOS expression by the endothelial cells.
7	17962866	Tumor necrosis factor affects insulin receptor substrate phosphorylation, resulting in decreased glucose uptake and compensatory hyperinsulinemia.
8	21386087	Stress stimuli such as tumor necrosis factor (TNF) have been shown to induce insulin receptor substrate (IRS)-1 serine phosphorylation and insulin resistance by transactivation of ErbB receptors.
