概括

这项研究使用了门德尔的随机化来研究肠道细菌和肺动脉高血压 (PAH) 之间的因果关系. 某些肠道微生物可能会增加PAH的风险,而其他微生物似乎具有保护性,为PAH研究提供了新的途径.

科学领域:

微生物组研究的研究.
遗传学遗传学是一个
心血管疾病是什么心血管疾病

背景情况:

肠道微生物组成越来越多地与肺动脉高血压 (PAH) 相关.
肠道失调症和PAH之间的因果关系尚不清楚.

研究的目的:

调查肠道微生物群和PAH之间的潜在因果关系,使用双样本门德尔随机化 (MR) 方法.
识别可能影响发展PAH的风险的特定肠道细菌.

主要方法:

使用了两个样本的门德尔随机化 (MR) 分析.
从MiBioGen联盟 (n=18,340) 中提取了196种细菌特征的遗传变异.
从NHGRI-EBI GWAS目录 (n=11,744) 获得了PAH总结统计数据,并采用了各种MR估计和灵敏度分析.

主要成果:

在Eubacterium fissicatena属的组中,与PAH有显著的因果关系 (OR 1.471).
拉克诺斯皮拉属UCG004和鲁米诺可可属UCG002表明PAH的风险增加.
欧细菌Eligens组,Phascolarctobacterium,Erysipelatoclostridium和T-yzzerella 3表现出对PAH的名义上的保护作用.

结论:

这项MR研究表明,肠道微生物群和PAH之间存在潜在的因果关系.
确定了对PAH具有保护性或有害影响的特定肠道细菌,指导未来的研究.

关键词:

在GWAS中,GWAS就是GWAS.我们的肠道微生物群.门德尔的随机化肺动脉高血压是肺动脉高血压.

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...

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...
