Abstract

Obesity is an epidemic in Western society, and causes rapidly accelerating rates of type 2 diabetes and cardiovascular disease. The evolutionarily conserved serine/threonine kinase, AMP-activated protein kinase (AMPK), functions as a 'fuel gauge' to monitor cellular energy status. We investigated the potential role of AMPK in the hypothalamus in the regulation of food intake. Here we report that AMPK activity is inhibited in arcuate and paraventricular hypothalamus (PVH) by the anorexigenic hormone leptin, and in multiple hypothalamic regions by insulin, high glucose and refeeding. A melanocortin receptor agonist, a potent anorexigen, decreases AMPK activity in PVH, whereas agouti-related protein, an orexigen, increases AMPK activity. Melanocortin receptor signalling is required for leptin and refeeding effects on AMPK in PVH. Dominant negative AMPK expression in the hypothalamus is sufficient to reduce food intake and body weight, whereas constitutively active AMPK increases both. Alterations of hypothalamic AMPK activity augment changes in arcuate neuropeptide expression induced by fasting and feeding. Furthermore, inhibition of hypothalamic AMPK is necessary for leptin's effects on food intake and body weight, as constitutively active AMPK blocks these effects. Thus, hypothalamic AMPK plays a critical role in hormonal and nutrient-derived anorexigenic and orexigenic signals and in energy balance.

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?

  • During starvation, ACC phosphorylation is mainly controlled by AMPK.

    “During starvation, ACC phosphorylation is mainly controlled by the well-known energy sensor, AMPK ([115](#B115)), which acts also as an important hub, integrating in-cell energetic state sensing and its modulation due to different circulating hormones.”

    From Mitochondrial fatty acid oxidation in obesity (2013) · cites this paper as [115]

  • Inhibition of hypothalamic AMPK lowers food intake and hepatic glucose production, while increasing hypothalamic AMPK has the opposite effect.

    “inhibition of hypothalamic AMPK (using an adenovirus expressing the dominant negative form of AMPK) lowers food intake and HGP, while increasing hypothalamic AMPK has the opposite effect (113, 209)”

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.
