Abstract:
OBJECTIVE: Our study is applying a community-based approach to examine the influence of exercise on gut microbiota (GM) and discover GM structures linked with NAFLD improvements during exercise. The majority of microbiome research has focused on finding specific species that may contribute to the development of human diseases. However, we believe that complex diseases, such as NAFLD, would be more efficiently treated using consortia of species, given that bacterial functionality is based not only on its own genetic information but also on the interaction with other microorganisms. Our results revealed that exercise significantly changes the GM interaction and that structural alterations can be linked with improvements in intrahepatic lipid content and metabolic functions. We believe that the identification of these characteristics in the GM enhances the development of exercise treatment for NAFLD and will attract general interest in this field.
摘要:
在非酒精性脂肪性肝病(NAFLD)中观察到肠道微生物菌群失调。锻炼的有益影响,建议改变NAFLD患者的生活方式,可能是由肠道微生物组(GM)介导的。然而,NAFLD患者运动过程中与宿主临床和生化改善相关的确切分类和功能特征尚未阐明.探讨运动对GM的影响,揭示运动过程中与NAFLD改善相关的GM结构。对NAFLD受试者(N=39)进行为期12周的随机对照运动研究,在基线和终点进行鸟枪宏基因组学。应用差异相关网络和富集分析来表征运动干预期间的GM分类和功能变化,并将GM变化与肝脏状态和代谢失调的生物标志物相关联。网络分析表明,运动引起细菌相互作用组的显著变化,与腰围有关;静息代谢率;血浆空腹甘油三酯浓度,葡萄糖,胰岛素,和糖化血红蛋白A1c;以及胰岛素抵抗的稳态模型评估。将运动组(N=20)中的患者分组为应答者(N=13)和非应答者(N=7),使用他们的肝内脂质含量(IHL)变化使我们能够鉴定有助于丙氨酸发酵水平的细菌聚生体,甲醇-,肌氨酸-,和原儿茶酸降解,并作为结果的肝损伤标志物丙氨酸转氨酶的血浆浓度,γ-谷氨酰转氨酶,和天冬氨酸转氨酶.我们表明,即使运动对NAFLD患者的α-和β-多样性没有显著影响,它导致了肠道细菌相互作用组的重大重组,并且特定的结构变化可能与IHL的改善有关。重要性我们的研究正在应用基于社区的方法来检查运动对肠道微生物群(GM)的影响,并发现与运动期间NAFLD改善相关的GM结构。大多数微生物组研究都集中在寻找可能导致人类疾病发展的特定物种。然而,我们相信复杂的疾病,比如NAFLD,使用物种联盟会更有效地处理,鉴于细菌的功能不仅基于其自身的遗传信息,还基于与其他微生物的相互作用。我们的结果表明,运动显着改变了GM相互作用,并且结构改变可以与肝内脂质含量和代谢功能的改善有关。我们认为,在GM中识别这些特征可以增强NAFLD运动治疗的发展,并将引起该领域的普遍兴趣。
