概括

这项研究发现,肠道细菌Rikenellaceae家族和代谢物X-11538可以预防牛皮关节炎 (PsA). 这些发现为PsA预防和治疗提供了潜在的新生物标志物.

科学领域:

遗传学是一个遗传学.
微生物学微生物学
免疫学免疫学免疫学

背景情况:

牛皮关节炎 (PsA) 患者与健康个体相比,肠道微生物组 (GM) 和血清代谢物发生变化.
以前对肠道微生物群/PsA代谢物的研究已经产生了不一致的结果.
门德尔随机化 (MR) 用于研究转基因/代谢物与PSA之间的因果关系.

研究的目的:

确定肠道微生物组 (GM) 种群和血清代谢物对牛皮关节炎 (PsA) 的因果关系.
为了确定PsA预防和治疗的潜在生物标志物.
探索代谢和PsA之间的关系背后的分子机制.

主要方法:

两个样本的孟德尔随机化 (MR) 分析使用总结级GWAS数据对GM/代谢物和PsA.
主要分析采用了反变量加权 (IVW) 方法.
敏感性分析包括多变量MR (MVMR),LDSC回归,施泰格测试和反向MR,以确保稳定性和调查反向因果关系.

主要成果:

发现8种转基因种类和23种血清代谢物与PsA有因果关系 (P <0.05).
增加了Rikenellaceae家族的丰富度和血清X-11538的升高显示出对PsA的保护作用 (FDR<0.05).
功能丰富分析将eQTL与糖脂代谢,细菌感染 (Vibrio cholerae,Helicobacter pylori) 和mTOR信号通路联系起来.

结论:

瑞肯氏家族和血清代谢物X-11538与PsA有显著的负因果关系,这表明它们具有保护作用.
这些发现突出了PsA潜在的新生物标志物.
细菌感染和mTOR介导的代谢因子激活可能与PsA的发病有关.

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...

Irritable Bowel Syndrome I: Introduction

Irritable Bowel Syndrome I: Introduction

Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...
