Abstract

Although obesity has become the most common metabolic disorder in the developed world and is highly associated with insulin resistance and noninsulin-dependent diabetes mellitus, the molecular mechanisms underlying these disorders are not clearly understood. Tumor necrosis factor-alpha (TNF-alpha) is overexpressed in obesity and is a candidate mediator of obesity-induced insulin resistance. Complete lack of TNF-alpha function through targeted mutations in TNF-alpha gene or both of its receptors results in significant improvement of insulin sensitivity in dietary, chemical, or genetic models of rodent obesity. In this study, we have analyzed the in vivo role of TNF signaling from p55 [TNF receptor (TNFR) 1] and p75 (TNFR 2) TNFR in the development of insulin resistance by generating genetically obese mice (ob/ob) lacking p55 or p75 TNFRs. In the ob/ob mice, the absence of p55 caused a significant improvement in insulin sensitivity. p75 deficiency alone did not affect insulin sensitivity but might potentiate the effects of p55 deficiency in animals lacking both TNFRs. These results indicate that TNF-alpha is a component of insulin resistance in the ob/ob model of murine obesity and p55 TNFR is the predominant receptor mediating its actions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
