Recently, the role of gut microbiota in the development of obesity and type 2 diabetes mellitus (T2DM) has been highlighted. We performed an 8-week administration protocol on T2DM (C57BL/6J db-/db-) mice and fecal samples were collected. Comparisons of fecal bacterial communities were performed between db-/db- mice and normal mice (DB/DB) and between the db-/db mice treated and untreated with AOE using next-generation sequencing technology. Our results showed that the db-/db-AOE group had improved glycemic control and renal function compared with the db-/db-HO group. Compared with the db-/db-HO group, AOE administration resulted in significantly increased ratio of Bacteroidetes-to-Firmicutes in db-/db- mice. In addition, the abundance of was significantly increased, while was significantly suppressed in the db-/db-AOE group compared with the db-/db-HO group. Our data suggest that AOE treatment decreased blood glucose levels and significantly reduced damage of renal pathology in the T2DM mice by modulating gut microbiota composition.
最近,肠道微生物群在肥胖和 2 型糖尿病(T2DM)的发展中的作用受到了重视。我们对 T2DM(C57BL/6J db-/db-)小鼠进行了为期 8 周的给药方案,收集粪便样本。使用下一代测序技术,比较了 db-/db-小鼠和正常小鼠(DB/DB)之间以及用 AOE 处理和未处理的 db-/db-小鼠之间的粪便细菌群落。我们的结果表明,与 db-/db-HO 组相比,db-/db-AOE 组的血糖控制和肾功能得到改善。与 db-/db-HO 组相比,AOE 给药导致 db-/db-小鼠中厚壁菌门与拟杆菌门的比例显著增加。此外,与 db-/db-HO 组相比,db-/db-AOE 组中的 丰度显著增加,而 丰度显著受到抑制。我们的数据表明,AOE 治疗通过调节肠道微生物群落组成降低了 T2DM 小鼠的血糖水平,并显著减轻了肾脏病理损伤。
