Obesity and related metabolic disorders are associated with intestinal microbiota dysbiosis, disrupted intestinal barrier, and chronic inflammation. Neohesperidin (Neo), a natural polyphenol abundant in citrus fruits, is known for its preventative and therapeutic effects on numerous diseases. Here, we report that Neo administration attenuates weight gain, low‐grade inflammation, and insulin resistance in mice fed high‐fat diet (HFD). Also, Neo administration substantially restores gut barrier damage, metabolic endotoxemia, and systemic inflammation. Sequencing of 16S rRNA genes in fecal samples revealed that Neo administration reverses HFD‐induced intestinal microbiota dysbiosis: an increase in the diversity of gut microbiota and alteration in the composition of intestinal microbiota (particularly in the relative abundances of Bacteroidetes and Firmicutes). Furthermore, systemic antibiotic treatment abolishes the beneficial effects of Neo in body weight control, suggesting that the effect of Neo on obesity attenuation largely depends on the gut microbiota. More importantly, we demonstrate that the impact of Neo on the regulation of obesity could be transferred from Neo‐treated mice to HFD‐fed mice via fecal microbiota transplantation. Collectively, our data highlight the efficacy of Neo as a prebiotic agent for attenuating obesity, implying a potential mechanism for gut microbiota mediated the beneficial effect of Neo.

新橙皮苷通过改变高脂饮食喂养小鼠肠道微生物群的组成来减轻肥胖

肥胖和相关代谢紊乱与肠道微生物群失调、肠道屏障破坏和慢性炎症有关。新橙皮苷 (Neo) 是柑橘类水果中富含的一种天然多酚,以其对多种疾病的预防和治疗作用而闻名。在这里,我们报告了 Neo 给药可减轻喂食高脂肪饮食 (HFD) 的小鼠的体重增加、轻度炎症和胰岛素抵抗。此外,Neo 给药可显着恢复肠道屏障损伤、代谢性内毒素血症和全身炎症。粪便样本中 16S rRNA 基因的测序显示,Neo 给药可逆转 HFD 诱导的肠道微生物群失调:肠道微生物群多样性的增加和肠道微生物群组成的改变(特别是拟杆菌和厚壁菌的相对丰度)。此外,全身抗生素治疗消除了 Neo 在体重控制中的有益作用,这表明 Neo 对减轻肥胖的影响在很大程度上取决于肠道微生物群。更重要的是,我们证明了 Neo 对肥胖调节的影响可以通过粪便微生物群移植从 Neo 治疗的小鼠转移到 HFD 喂养的小鼠。总的来说,我们的数据突出了 Neo 作为减轻肥胖症的益生元药物的功效,暗示了肠道微生物群介导 Neo 有益作用的潜在机制。全身抗生素治疗消除了 Neo 在控制体重方面的有益作用,这表明 Neo 对减轻肥胖的影响在很大程度上取决于肠道微生物群。更重要的是,我们证明了 Neo 对肥胖调节的影响可以通过粪便微生物群移植从 Neo 治疗的小鼠转移到 HFD 喂养的小鼠。总的来说,我们的数据突出了 Neo 作为减轻肥胖症的益生元药物的功效,暗示了肠道微生物群介导 Neo 有益作用的潜在机制。全身抗生素治疗消除了 Neo 在控制体重方面的有益作用,这表明 Neo 对减轻肥胖的影响在很大程度上取决于肠道微生物群。更重要的是,我们证明了 Neo 对肥胖调节的影响可以通过粪便微生物群移植从 Neo 治疗的小鼠转移到 HFD 喂养的小鼠。总的来说,我们的数据突出了 Neo 作为减轻肥胖症的益生元药物的功效,暗示了肠道微生物群介导 Neo 有益作用的潜在机制。
