Signalling by insulin and IGF receptors: supporting acts and new players

Open access
Siddle, Kenneth·2011·Journal of Molecular Endocrinology

Abstract

The signalling pathways utilised by insulin receptor (IR) and IGF receptor to transduce their diverse effects on cellular metabolism, growth and survival are well established in broad outline, but many details remain to be elucidated. Tyrosine phosphorylation of IR substrates and Shc initiates signalling via canonical phosphoinositide 3-kinase/Akt and Ras/MAP kinase pathways, which together mediate many of the actions of insulin and IGFs. However, a variety of additional substrates and scaffolds have been described that may play roles in modulating the canonical pathways or in specific biological responses. This review will focus on recent studies that have extended our understanding of insulin/IGF signalling pathways, and the elements that may contribute to specificity.

  • IGF-1 has been shown to stimulate the β-catenin pathway through signaling cascades involving the activation of phosphatidylinositol 3-kinase (PI 3-K)/Akt and the inhibition of glycogen synthase kinase-3 (GSK-3).

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.
