Abstract

Scope: Docosahexaenoic acid (DHA; C22: 6, n‐3), one of PUFAs, exerts beneficial effects on inflammatory diseases, obesity and diabetes. Angiogenesis in adipose tissue has a major role in the development of obesity and its related metabolic complications. Inhibition of angiogenesis is an emerging strategy for the novel treatment for obesity. Thus, we examined the effect of DHA on angiogenesis in adipose tissues and investigated the underlying mechanisms. Methods and results: In high‐fat diet (HFD) fed middle‐aged mice, DHA inhibited the macrophage‐derived inflammation and angiogenesis in adipose tissues, reduced adipocyte size and body fat composition and improved insulin sensitivity. Moreover, DHA reversed the HFD‐induced reduction of Sirt1 in adipose tissues. Interestingly, the effects of DHA were attenuated by lentivirus‐mediated Sirt1 knockdown with increasing expression of markers of macrophage‐derived inflammation and angiogenesis, associated with impaired insulin sensitivity. Conclusion: Overall, our findings demonstrated that DHA reduced angiogenesis of adipose tissues and attenuated insulin resistance in HFD‐induced obese mice via the activation of Sirt1.

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.
