Abstract

Prenatal testosterone (T) excess in sheep leads to peripheral insulin resistance (IR), reduced adipocyte size, and tissue-specific changes, with liver and muscle but not adipose tissue being insulin resistant. To determine the basis for the tissue-specific differences in insulin sensitivity, we assessed changes in negative (inflammation, oxidative stress, and lipotoxicity) and positive mediators (adiponectin and antioxidants) of insulin sensitivity in the liver, muscle, and adipose tissues of control and prenatal T–treated sheep. Because T excess leads to maternal hyperinsulinemia, fetal hyperandrogenism, and functional hyperandrogenism and IR in their female offspring, prenatal and postnatal interventions with antiandrogen, flutamide, and the insulin sensitizer rosiglitazone were used to parse out the contribution of androgenic and metabolic pathways in programming and maintaining these defects. Results showed that (1) peripheral IR in prenatal T–treated female sheep is related to increases in triglycerides and 3-nitrotyrosine, which appear to override the increase in high-molecular-weight adiponectin; (2) liver IR is a function of the increase in oxidative stress (3-nitrotyrosine) and lipotoxicity; (3) muscle IR is related to lipotoxicity; and (4) the insulin-sensitive status of visceral adipose tissue appears to be a function of the increase in antioxidants that likely overrides the increase in proinflammatory cytokines, macrophages, and oxidative stress. Prenatal and postnatal intervention with either antiandrogen or insulin sensitizer had partial effects in preventing or ameliorating the prenatal T–induced changes in mediators of insulin sensitivity, suggesting that both pathways are critical for the programming and maintenance of the prenatal T–induced changes and point to potential involvement of estrogenic pathways.

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?

  • In female offspring, excess androgen exposure changes the size of WAT adipocytes and increases chemokine and pro-inflammatory cytokine expression and dysregulated adiponectin expression, depending on the timing of exposure and WAT depot.

    “There is a change in the size of WAT adipocytes [132, 136] and an increase in chemokine and pro-inflammatory cytokine expression and dysregulated adiponectin expression, depending on the timing of the androgen exposure and WAT depot in female offspring [132, 137].”
  • In experimental animals, excess androgen exposure in utero or in early neonatal life programmes the female offspring to have changes in adipose tissue biology.

    “As shown in Table 7, work in experimental animals has shown that excess androgen exposure in utero or in early neonatal life programmes the female offspring to have changes in adipose tissue biology [132–135].”

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.
