Inflammation and the IKKβ/IκB/NF-κB axis in obesity- and diet-induced insulin resistance

Shoelson, S E, Lee, J, Yuan, M·2003·International Journal of Obesity

Abstract

Antidiabetic effects associated with salicylates have been known for years, although the underlying mechanisms were not understood. We have been reinvestigating these effects in the light of recent discoveries in the areas of signal transduction and insulin resistance. Our findings showed that signaling pathways leading to I kappa B kinase beta (IKK beta) and NF-kappa B are activated in insulin-responsive tissues of obese and high-fat-fed animals. Since activation correlates with the development of insulin resistance, we asked whether signaling through this might be involved in the pathogenesis of insulin resistance. Heterozygous gene deletion (Ikk beta+/-) or salicylates, working as IKK beta inhibitors, improved insulin sensitivity in insulin-resistant rodent models. Furthermore, high doses of salicylates (aspirin or salicylate) improved insulin sensitivity in patients with type II diabetes. Our studies implicate an inflammatory process in the pathogenesis of insulin resistance in obesity and type II diabetes mellitus and identify the IKK beta/NF-kappa B pathway as a molecular mediator of insulin resistance and pharmacological target for insulin sensitization.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Inflammatory molecules are likely candidates linking adipose tissue to metabolic, cardiovascular, hepatic and thrombotic complications and certain cancers in obesity.

    “Inflammatory molecules are likely candidates exerting a molecular link between the adipose tissue and the metabolic, cardiovascular, hepatic and thrombotic complications, and certain cancer types occurring in conjunction with or as a consequence of human obesity.”

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.
