Abstract

Adipokines play important roles in metabolic homeostasis and disease. We have recently identified a novel adipokine Metrnl, also known as Subfatin, for its high expression in subcutaneous fat. Here, we demonstrate a prodifferentiation action of Metrnl in white adipocytes. Adipocyte-specific knockout of Metrnl exacerbates insulin resistance induced by high-fat diet (HFD), whereas adipocyte-specific transgenic overexpression of Metrnl prevents insulin resistance induced by HFD or leptin deletion. Body weight and adipose content are not changed by adipocyte Metrnl. Consistently, no correlation is found between serum Metrnl level and BMI in humans. Metrnl promotes white adipocyte differentiation, expandability, and lipid metabolism and inhibits adipose inflammation to form functional fat, which contributes to its activity against insulin resistance. The insulin sensitization of Metrnl is blocked by PPARγ inhibitors or knockdown. However, Metrnl does not drive white adipose browning. Acute intravenous injection of recombinant Metrnl has no hypoglycemic effect, and 1-week intravenous administration of Metrnl is unable to rescue insulin resistance exacerbated by adipocyte Metrnl deficiency. Our results suggest adipocyte Metrnl controls insulin sensitivity at least via its local autocrine/paracrine action through the PPARγ pathway. Adipocyte Metrnl is an inherent insulin sensitizer and may become a therapeutic target for insulin resistance.

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.
