Abstract

Obesity-related insulin resistance represents the core component of the metabolic syndrome, promoting glucose intolerance, pancreatic beta cell failure and type 2 diabetes. Efficient and safe insulin sensitization and glucose control remain critical therapeutic aims to prevent diabetic late complications Here, we identify transforming growth factor beta-like stimulated clone (TSC) 22 D4 as a molecular determinant of insulin signalling and glucose handling. Hepatic TSC22D4 inhibition both prevents and reverses hyperglycaemia, glucose intolerance and insulin resistance in diabetes mouse models. TSC22D4 exerts its effects on systemic glucose homeostasis-at least in part-through the direct transcriptional regulation of the small secretory protein lipocalin 13 (LCN13). Human diabetic patients display elevated hepatic TSC22D4 expression, which correlates with decreased insulin sensitivity, hyperglycaemia and LCN13 serum levels. Our results establish TSC22D4 as a checkpoint in systemic glucose metabolism in both mice and humans, and propose TSC22D4 inhibition as an insulin sensitizing option in diabetes therapy.

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

  • Both mRNA and plasma levels of LCN13 are low in mice with genetic or high-fat diet-induced obesity.

    “both mRNA and plasma levels of LCN13 are low in mice with genetic or high-fat diet-induced obesity [254,257].”
  • Plasma levels of LCN13 decrease in patients with obesity and type 2 diabetes.

    “Plasma levels of LCN13 decrease in patients with obesity and type 2 diabetes [257]”
  • Knockdown of LCN13 or administration of recombinant LCN13 protein in mice have no significant effects on body weight or adipose tissue mass compared with control animals.

    “Interestingly, knockdown of LCN13 or administration of recombinant LCN13 protein in mice have no significant effects on body weight or adipose tissue mass compared with control animals [257].”

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.
