Dietary Lactate Supplementation Protects against Obesity by Promoting Adipose Browning in Mice

Abstract

Yogurt has been widely used in weight-loss foods to prevent obesity, but its molecular nature remains unclear. Lactate is a major ingredient of yogurt, while its cognate cell surface receptor GPR81 is highly expressed in adipose tissues in mammals. Here we hypothesized that dietary lactate supplementation might activate GPR81 to promote adipose browning. Studying mouse models, we observed that GPR81 was substantially lowered in adipose tissue of obese mice compared with that for lean ones, whereas its expression was markedly up-regulated by a β3-adrenergic receptor (β3-AR) agonist. The deficiency of GPR81 greatly attenuated experimental adipose browning and thermogenesis. Importantly, oral administration of lactate effectively induced adipose browning, enhanced thermogenesis, improved dyslipidemia, and protected mice against high-fat-diet-induced obesity. Mechanistically, p38 mitogen-activated protein kinase might serve as a key downstream effect or of GPR81. Collectively, our findings revealed a critical role of GPR81 in adipose browning and provided a new insight into obesity management by modulating lactate-GPR81 signaling axis.

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.
