Gut:遗传和宿主遗传学对肠道菌群和代谢综合征的影响

2017-05-17 zhangfan MedSci原创

特定的宿主基因型介导的微生物组成变化可以导致代谢综合征

代谢综合征(MetS)是由宿主遗传和环境因素之间复杂的相互作用产生。人们普遍认为肠道微生物在宿主代谢中起着至关重要的作用,但目前关于宿主遗传学对于特定肠道微生物影响的认识仍然有限。近日研究人员就宿主遗传因素,人类肠道微生物与代谢综合征三者的关系进行研究。

研究人员306名同卵双胞胎、74名异卵双胞胎以及其275名亲属的肠道微生物群落组成特征进行研究。研究对象中有121人(18%)患有代谢综合征。研究人员评估了胃肠道菌群状态和每个类群的遗传力的关系。研究人员进一步通过载脂蛋白(APOA5)基因单核苷酸多态性(SNP)研究遗传因素和代谢综合征之间的关系。

研究发现,代谢综合征患者肠道微生物多样性低于健康个体,类群的丰度与代谢综合征状态相关:代谢综合征组患者其萨特菌、短杆菌和乳酸菌含量高,健康人群中Akkermansia,odoribacter和双歧杆菌含量高。双歧杆菌属的他门放线菌具有最高的遗传力(45.7%)。放线菌和双歧杆菌含量降低与APOA5 SNP rs651821等位基因显著相关。

研究表明特定的宿主基因型介导的微生物组成变化可以导致代谢综合征。
