Description:
Tumor necrosis factor-alpha (TNF-alpha) has been shown to have certain catabolic effects on fat cells and whole animals. An induction of TNF-alpha messenger RNA expression was observed in adipose tissue from four different rodent models of obesity and diabetes. TNF-alpha protein was also elevated locally and systemically. Neutralization of TNF-alpha in obese fa/fa rats caused a significant increase in the peripheral uptake of glucose in response to insulin. These results indicate a role for TNF-alpha in obesity and particularly in the insulin resistance and diabetes that often accompany obesity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hotamisligil, G S -- Shargill, N S -- Spiegelman, B M -- DK 42539/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1993 Jan 1;259(5091):87-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7678183" target="_blank"〉PubMed〈/a〉
