概括

这项研究表明,肠道微生物群 (GM) 具有因果关系,影响着心房动 (AF) 风险. 一些细菌,如Actinobacteria具有保护作用,而其他细菌,如Oxalobacter,增加了AF风险.

科学领域:

遗传学遗传学是一种遗传学.
微生物学微生物学
心脏病学心脏病学

背景情况:

以前的研究已经在心房 (AF) 中描述了肠道微生物群 (GM),但因果关系仍然不清楚.
了解GM和AF之间的双向关系对于新的治疗策略至关重要.

研究的目的:

通过全基因组关联研究 (GWAS) 调查肠道微生物群和心房动之间的因果关系.
识别与增加或减少AF风险相关的特定细菌种群.

主要方法:

采用双轮门德尔随机化 (MR) 分析,使用单核酸多态 (SNP) 作为仪器变量.
适用于SNP选择的全基因组和全位点显著性值.
进行敏感性分析以评估异质性和性.

主要成果:

确定了特定的转基因种类,它们对AF风险具有显著的因果影响,无论是在全位点还是全基因组的显著水平上.
发现了Actinobacteria,Firmicutes,Bifidobacterium和其他人的保护性关联.
观察到与Pasteurellales,Oxalobacter和Erysipelatoclostridium相关的AF风险增加.
敏感性分析表明,某些种类的潜在异质性.

结论:

这项研究提供了强有力的证据,证明肠道微生物群在心房动中起因作用.
证明了特定的转基因对AF发展的有益和有害影响.

Anatomy of the Intestines

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
