Abstract

Intrauterine growth restriction (IUGR) increases the risk for metabolic disease and diabetes, although the developmental origins of this remain unclear. We measured glucose metabolism during basal and insulin clamp periods in a fetal sheep model of placental insufficiency and IUGR. Compared with control fetuses (CON), fetuses with IUGR had increased basal glucose production rates and hepatic PEPCK and glucose-6-phosphatase expression, which were not suppressed by insulin. In contrast, insulin significantly increased peripheral glucose utilization rates in CON and IUGR fetuses. Insulin robustly activated AKT, GSK3β, and forkhead box class O (FOXO)1 in CON and IUGR fetal livers. IUGR livers, however, had increased basal FOXO1 phosphorylation, nuclear FOXO1 expression, and Jun NH2-terminal kinase activation during hyperinsulinemia. Expression of peroxisome proliferator–activated receptor γ coactivator 1α and hepatocyte nuclear factor-4α were increased in IUGR livers during basal and insulin periods. Cortisol and norepinephrine concentrations were positively correlated with glucose production rates. Isolated IUGR hepatocytes maintained increased glucose production in culture. In summary, fetal sheep with IUGR have increased hepatic glucose production, which is not suppressed by insulin despite insulin sensitivity for peripheral glucose utilization. These data are consistent with a novel mechanism involving persistent transcriptional activation in the liver that seems to be unique in the fetus with IUGR.

  • Maternal undernutrition may lead to foetal growth restriction, characterised by reduced pancreatic growth, impaired insulin secretion, and hepatic insulin resistance.

    “Maternal undernutrition may lead to foetal growth restriction (FGR), characterised by reduced pancreatic growth, impaired insulin secretion, and hepatic insulin resistance [28,29,30].”

    From Medical Nutrition Therapy for Women with Gestational Diabetes: Current Practice and Future Perspectives (2025) · cites this paper as [30]

    The Discussion (page unavailable) reports that insulin did not suppress hepatic glucose production in growth-restricted fetal sheep, and the introductory text reports decreased pancreatic insulin secretion in animal models of growth restriction. But the Methods (page unavailable) describe growth restriction induced by maternal heat exposure, not maternal undernutrition; our copy also does not establish reduced pancreatic growth.

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.
