Abstract

Omega-3 fatty acids (omega-3 FAs), DHA and EPA, exert anti-inflammatory effects, but the mechanisms are poorly understood. Here, we show that the G protein-coupled receptor 120 (GPR120) functions as an omega-3 FA receptor/sensor. Stimulation of GPR120 with omega-3 FAs or a chemical agonist causes broad anti-inflammatory effects in monocytic RAW 264.7 cells and in primary intraperitoneal macrophages. All of these effects are abrogated by GPR120 knockdown. Since chronic macrophage-mediated tissue inflammation is a key mechanism for insulin resistance in obesity, we fed obese WT and GPR120 knockout mice a high-fat diet with or without omega-3 FA supplementation. The omega-3 FA treatment inhibited inflammation and enhanced systemic insulin sensitivity in WT mice, but was without effect in GPR120 knockout mice. In conclusion, GPR120 is a functional omega-3 FA receptor/sensor and mediates potent insulin sensitizing and antidiabetic effects in vivo by repressing macrophage-induced tissue inflammation.

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

  • The anti-inflammatory effects of omega-3 fatty acids seem to be mediated by binding to the G-protein-coupled receptor 120 and inhibition of NLRP3 inflammasome activity.

    “The anti-inflammatory effects of omega-3 fatty acids seems to be mediated by binding to the G-protein–coupled receptor 120 and inhibition of NLRP3 inflammasome activity (53,54).”
  • In macrophages and adipocytes, the G-protein coupled receptor GPR120 is an omega-3 sensitive receptor that exhibits anti-inflammatory properties through the suppression of TNF-activation.

    “in macrophages and adipocytes the G-protein coupled receptor GPR120 is an omega-3 sensitive receptor that exhibits anti-inflammatory properties through the suppression of TNF-activation [141]”

    From Omega-3 Fatty Acids and Skeletal Muscle Health (2015) · cites this paper as [141]

  • GPR120 expression is negligible in skeletal muscle and would therefore not explain the changes induced by omega-3 PUFAs in tissue culture models.

    From Omega-3 Fatty Acids and Skeletal Muscle Health (2015) · cites this paper as [141]

  • n-3 PUFAs EPA and DHA can reduce inflammation via incorporation into membrane phospholipids, inhibiting production of pro-inflammatory eicosanoids and reducing activation of immune cells and release of pro-inflammatory cytokines.

    “In summary, the n-3 PUFAs EPA and DHA can reduce inflammation via their incorporation into membrane phospholipids, where they inhibit the production of pro-inflammatory eicosanoids, reducing of activation of immune cells and the associated release of pro-inflammatory cytokines [71,97,98].”

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.
