The aim of our study was to evaluate the anti-obesity effects of () ADM14 administration in a high-fat diet-induced obese mouse model and the resulting changes in the intestinal microbiota. Prior to in vivo testing, ADM14 was shown to inhibit adipogenesis through in vitro test and genetic analysis. Subsequently, mice were orally administered 0.85% saline supplemented or not with ADM14 to high-fat diet group and normal diet group daily. The results showed that administration of ADM14 reduced weight gain, epididymal fat expansion, and total blood cholesterol and glucose levels, and significantly decreased expression of lipid-related genes in the epididymal fat pad. Administration of ADM14 showed improvement in terms of energy harvesting while restoring the Firmicutes to Bacteroidetes ratio and also increased the relative abundance of specific microbial taxa such as and , which are abundant in non-obese people. ADM14 affected the modulation of gut microbiota, altered the strain profile of short-chain fatty acid production in the cecum and enhanced the stimulation of butyrate production. Overall, ADM14 showed potential as a therapeutic probiotic supplement for metabolic disorders, confirming the positive changes of in vivo indicators and controlling gut microbiota in a high-fat diet-induced obese mouse model.
我们的研究目的是评估 () ADM14 在高脂肪饮食诱导肥胖小鼠模型中的抗肥胖作用,以及肠道微生物群的变化。在体内试验之前,ADM14 通过体外试验和遗传分析显示出抑制脂肪生成的作用。随后,每日给高脂肪饮食组和正常饮食组的小鼠口服补充 0.85%盐水或不补充 ADM14。结果表明,ADM14 给药可减少体重增加、附睾脂肪扩张以及总血胆固醇和葡萄糖水平,并显著降低附睾脂肪垫中与脂质相关的基因表达。ADM14 给药在能量采集方面表现出改善,同时恢复厚壁菌门与拟杆菌门的比例,并增加特定微生物类群的相对丰度,如在非肥胖人群中丰富的 和 。ADM14 影响肠道微生物群的调节,改变盲肠中短链脂肪酸产生的菌株谱,并增强丁酸盐产生的刺激。总体而言,ADM14 作为代谢紊乱的治疗性益生菌补充剂具有潜力,证实了体内指标的积极变化,并控制了高脂肪饮食诱导肥胖小鼠模型中的肠道微生物群。
