Abstract

Significance: The lobules are the functional units of the liver. They consist of 15–25 layers of hepatocytes with specialized metabolic functions and gene expression patterns relative to their position along the lobule, a phenomenon referred to as metabolic zonation. The Wnt/β-catenin pathway regulates hepatocyte function but how the zonation is controlled to meet the metabolic demands of the liver is unclear. Glucagon regulates hepatic function. We now demonstrate that glucagon contributes to liver zonation by interacting and opposing the actions of the Wnt/β-catenin pathway.

  • Higher periportal availability of hormones, such as insulin and glucagon, play important opposing roles in spatial metabolic zonation and interact with the WNT/β-catenin pathway.

    “Higher periportal availability of hormones, such as insulin and glucagon, play important opposing roles in spatial metabolic zonation and interact with the WNT/β-catenin pathway.54”

    From Distinct hepatocyte identities in liver homeostasis and regeneration (2023) · cites this paper as [54]

    The Discussion (page not available in our copy) says glucagon acts more strongly in the periportal zone and counteracts WNT/β-catenin signaling in liver metabolic zonation. The Results call insulin a counterregulatory hormone of glucagon, but the paper does not establish higher periportal insulin availability or an insulin interaction with WNT/β-catenin.

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.
