概括

基本代谢率 (BMR) 有因果影响于类风湿性关节炎 (RA). 这项研究发现BMR会增加RA风险,但RA不会影响BMR,突出显示BMR会增加RA风险.

科学领域:

代谢研究的研究.
类风湿病学类风湿病学
遗传流行病学遗传流行病学

背景情况:

基础代谢率 (BMR) 是代谢的关键指标,与整体健康有关.
以前的研究表明,类风湿性关节炎 (RA) 发展和BMR之间存在联系,但因果关系仍然未确立.

研究的目的:

调查基底代谢率 (BMR) 和类风湿性关节炎 (RA) 之间的潜在因果关系.
探索BMR对不同形式的RA的影响,包括血清阳性和血清阴性RA.
检查RA是否影响BMR或相关生物标志物.

主要方法:

孟德尔随机化 (MR) 分析利用全基因组关联研究数据.
使用五种不同的MR分析方法 (IVW,MR-Egger,加权中位数,加权模式,简单模式).
进行灵敏度分析 (MR-PRESSO,MR-Radial) 以检测和纠正水平形变异并验证发现.

主要成果:

基础代谢率 (BMR) 对整体类风湿性关节炎 (RA) 的显著因果作用被确定 (OR=1.25,P=0.006).
BMR还显示了对血清阳性RA (OR=1.20,P=0.035) 和血清阴性RA (OR=1.36,P=0.023) 的因果关系.
没有证据表明RA对BMR或其与关键炎症标志物的关系有因果关系.

结论:

门德尔随机分析支持基底代谢率 (BMR) 在类风湿性关节炎 (RA) 病变发生过程中的因果作用.
这些发现强调了在了解和潜在地管理RA时考虑BMR的重要性.
进一步的研究可能会探索针对RA治疗中的代谢因素的治疗策略.

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...

The JAK-STAT Signaling Pathway

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

Metabolic Rate

Metabolic Rate

The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
Several factors influence...
