本研究的目的是检查补充紫苏油是否可以改善糖尿病 KKAy 小鼠的糖脂代谢并调节肠道微生物群。将成功建立的糖尿病KKAy小鼠随机分为四组:糖尿病模型(DM)、低剂量紫苏油(LPO)、中剂量紫苏油(MPO)和高剂量紫苏油(HPO)。 C57BL/6J 小鼠以饲料喂养作为正常对照 (NC)。 12 周结束时,对小鼠实施安乐死并分析糖脂指标。根据16S rRNA V4区的测序结果进行肠道微生物群分析。虽然血清葡萄糖、胰岛素、总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、基于丰度的覆盖估计量和香农没有变化,但与 DM 相比,LPO 中的血清甘油三酯显着降低。补充紫苏油可以改善肝细胞大泡脂肪变性和脂肪细胞肥大的组织病理学变化。与 DM 相比,Blautia 的 LPO、MPO 和 HPO 显着降低。非度量多维标度分析表明 NC 和 LPO 是相对一致的。这些发现表明,膳食补充紫苏油可以改善糖尿病 KKAy 小鼠的高甘油三酯血症和肠道菌群失调,这可能对人类健康有潜在益处。
The aim of this study is to examine whether perilla oil supplementation improves glucolipid metabolism and modulates gut microbiota in diabetic KKAy mice. The successfully established diabetic KKAy mice are randomized into four groups: diabetic model (DM), low‐dose perilla oil (LPO), middle‐dose perilla oil (MPO), and high‐dose perilla oil (HPO). C57BL/6J mice are fed a chow diet as normal control (NC). At the end of 12 weeks, mice are euthanized and glucolipid indications are analyzed. Gut microbiota analysis is carried out based on the sequencing results on V4 region of 16S rRNA. Although serum glucose, insulin, total cholesterol, low‐density lipoprotein cholesterol, high‐density lipoprotein cholesterol, abundance‐based coverage estimator, and shannon are unchanged, serum triglyceride significantly decreases in LPO compared with DM. The histopathological changes of hepatocellular macrovesicular steatosis and adipocyte hypertrophy are ameliorated by perilla oil supplementation. Blautia is significantly decreased in LPO, MPO, and HPO, compared with DM. Nonmetric multidimensional scaling analysis shows NC and LPO are relatively coherent. These findings indicate that dietary supplementation with perilla oil can improve hypertriglyceridemia and gut dysbiosis in diabetic KKAy mice, which can be associated with potential benefits to human health.
