Role of AMP-Activated Protein Kinase in the Control of Glucose Homeostasis

Barnes, B., Zierath, J.·2005·Current Molecular Medicine

Abstract

Skeletal muscle insulin resistance is a hallmark feature of Type 2 diabetes. Physical exercise/muscle contraction elicits an insulin-independent increase in glucose transport and perturbation of this pathway may bypass defective insulin signaling. To date, the exercise-responsive signaling molecules governing glucose metabolism in skeletal muscle are largely unknown. AMP-activated protein kinase (AMPK) has been suggested as one of the exercise-responsive signaling molecules involved in glucose homeostasis and consequently it has been heavily explored as a pharmacological target for the treatment of Type 2 diabetes. AMPK exists in heterotrimeric complexes composed of a catalytic alpha-subunit and regulatory beta- and gamma-subunits. The gamma3-isoform of AMPK is expressed specifically in skeletal muscle of humans and rodents and this tissue specific expression pattern offers selectivity in AMPK action. Furthermore, mutations in the AMPK gamma3-isoform may provide protection from diet-induced insulin resistance by increasing lipid oxidation in the presence of increased lipid supply. This review highlights the current understanding of the role of the regulatory AMPK gamma3-isoform in the control of skeletal muscle metabolism.

  • AMPK α2, β2 and γ3 null and α2KD and β1β2 M-KO mice have normal insulin-stimulated glucose uptake in muscle.

    “In support of this, insulin also does not increase AMPK T172 or ACC S79/212 phosphorylation [74] and AMPK α2, β2 and γ3 null and α2KD and β1β2 M-KO mice have normal insulin-stimulated glucose uptake in muscle [26,28,30,36,100] despite blunted TBC1D1 PAS and T590 phosphorylation in response to insulin [30,74].”

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.
