Abstract

Aims/hypothesis The role of IL-6 in the development of obesity and hepatic insulin resistance is unclear and still the subject of controversy. We aimed to determine whether global deletion of Il6 in mice (Il6 (-/-)) results in standard chow-induced and high-fat diet (HFD)-induced obesity, hepatosteatosis, inflammation and insulin resistance.Methods Male, 8-week-old Il6 (-/-) and littermate control mice were fed a standard chow or HFD for 12 weeks and phenotyped accordingly.Results Il6 (-/-) mice displayed obesity, hepatosteatosis, liver inflammation and insulin resistance when compared with control mice on a standard chow diet. When fed a HFD, the Il6 (-/-) and control mice had marked, equivalent gains in body weight, fat mass and ectopic lipid deposition in the liver relative to chow-fed animals. Despite this normalisation, the greater liver inflammation, damage and insulin resistance observed in chow-fed Il6 (-/-) mice relative to control persisted when both were fed the HFD. Microarray analysis from livers of mice fed a HFD revealed that genes associated with oxidative phosphorylation, the electron transport chain and tricarboxylic acid cycle were uniformly decreased in Il6 (-/-) relative to control mice. This coincided with reduced maximal activity of the mitochondrial enzyme β-hydroxyacyl-CoA-dehydrogenase and decreased levels of mitochondrial respiratory chain proteins.Conclusions/interpretation Our data suggest that IL-6 deficiency exacerbates HFD-induced hepatic insulin resistance and inflammation, a process that appears to be related to defects in mitochondrial metabolism.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • IL-6−/− mice exhibit hepatosteatosis, insulin resistance, and liver inflammation.

    “The anti-inflammatory properties of IL-6 are illustrated by IL-6−/− mice, which exhibit hepatosteatosis, insulin resistance, and liver inflammation (44).”
  • In these same contexts, others have shown that IL6 induces insulin sensitivity, while IL6 has been shown to be insulin sensitizing in exercise.

    “On the other hand, in these same contexts, others have shown that IL6 induces insulin sensitivity (Carey et al., 2006; Findeisen et al., 2019; Matthews et al., 2010; Mauer et al., 2014; Steensberg et al., 2003; Timper et al., 2017), while IL6 has been shown to be insulin sensitizing in exercise (Benrick et al., 2012).”

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.
