Abstract

Excessive energy intake leads to dysbiosis of intestinal microbiota and puts surrounding tissues under oxidative stress and inflammation, contributing to the development of metabolic syndrome. Taiwanese green propolis (TGP) exhibits a broad spectrum of biological activities, including anti-bacterial, anti-inflammatory, and antioxidant properties. However, the benefits of TGP on metabolic syndrome have not been explained in detail. In this study, we examined the preventive effects of TGP on high-fat diet (HFD)-induced obesity. The results showed that TGP supplementation at 1000 ppm improved condition such as hyperlipidemia, fat accumulation, liver steatosis, and whitening of brown adipose tissue (BAT) in mice. In addition, we observed more cold-induced non-shivering thermogenesis by BAT in TGP treatment with 1000 ppm group. At lower dose of 500 ppm, TGP improved glucose intolerance and insulin insensitivity in HFD mice and restructured the composition of gut microbiota to reduce dysbiosis, which involved an increase in the abundance of metabolism-related bacteria such as Lachnospiraceae NK4A136 group and the decrease in Desulfovibrio. The change of dominant microbiota was associated with the homeostasis of blood glucose and lipid. Transcriptome and micro-western array analysis revealed that TGP supplementation at 500 ppm promoted the browning and adipogenesis in white adipose tissue (WAT), blocked inflammation signaling and attenuated reactive oxygen species, contributing to healthy WAT remodeling and offsetting negative metabolic effects of obesity. We concluded that TGP modulated the function of BAT, WAT, and gut microbiota, bringing a balance to the glucose and lipid homeostasis in the body.

Claims other papers make about this one

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

  • Omega-3 PUFAs from Nannochloropsis and Schizochytrium improve lipid profiles, enhance insulin sensitivity, and regulate inflammation via PPAR and AMPK signalling pathways.

    “Omega-3 PUFAs, mainly those from Nannochloropsis and Schizochytrium, have been shown to improve lipid profiles, enhance insulin sensitivity, and regulate inflammation via the peroxisome proliferator-activated receptor (PPAR) and AMP-activated protein kinase (AMPK) signalling pathways [22].”
  • Carotenoids such as fucoxanthin stimulate thermogenesis by upregulating UCP1 in white adipose tissue and activating AMPK pathways to enhance glucose uptake in skeletal muscles.

    “Carotenoids, such as fucoxanthin derived from Phaeodactylum tricornutum and Isochrysis galbana, stimulate thermogenesis by upregulating uncoupling protein 1 (UCP1) expression in white adipose tissue while simultaneously activating AMPK pathways to enhance glucose uptake in skeletal muscles [22].”
  • Fucoxanthin activates the AMPK pathway, enhancing glucose uptake in skeletal muscle tissue.

    “Fucoxanthin activates the AMPK pathway, enhancing glucose uptake in skeletal muscle tissue [22].”

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.
