Metabolic disorders and intestinal flora imbalance usually accompany obesity. Due to its diverse biological activities, is widely used to alleviate various diseases as a probiotic. Here, we show that can reduce the body weight of mice fed high-fat diets, reduce fat accumulation, and enhance mice glucose tolerance. Our results show that can significantly reduce the expression of DGAT1 and DGAT2, increase the expression of Cpt1a, and promote the process of lipid metabolism. Further data show that can increase the SCFA content in the colon and reverse the intestinal flora disorder caused by HFD, increase the abundance of , and , and reduce the abundance of and . Finally, through Pearson correlation analysis, we found that and SCFAs are positively correlated, while are negatively correlated with SCFAs. Therefore, we believe that can regulate the structure of the intestinal microbial community, increase the production of SCFAs and thus regulate lipid metabolism.
代谢紊乱和肠道菌群失衡通常伴随着肥胖。由于其多样的生物活性,作为一种益生菌被广泛用于缓解各种疾病。在此,我们表明[具体物质未提及]可以降低高脂饮食喂养小鼠的体重,减少脂肪堆积,并增强小鼠的葡萄糖耐受性。我们的结果表明[具体物质未提及]可以显著降低二酰甘油酰基转移酶1(DGAT1)和二酰甘油酰基转移酶2(DGAT2)的表达,增加肉碱棕榈酰转移酶1a(Cpt1a)的表达,并促进脂质代谢过程。进一步的数据表明[具体物质未提及]可以增加结肠中短链脂肪酸(SCFA)的含量,并逆转高脂饮食(HFD)引起的肠道菌群紊乱,增加[具体菌属未提及1]和[具体菌属未提及2]的丰度,并降低[具体菌属未提及3]和[具体菌属未提及4]的丰度。最后,通过Pearson相关性分析,我们发现[具体物质未提及]与SCFAs呈正相关,而[具体物质未提及]与SCFAs呈负相关。因此,我们认为[具体物质未提及]可以调节肠道微生物群落结构,增加SCFAs的产生,从而调节脂质代谢。
