概括
这项研究在全身性硬化症患者中发现了较低的阿迪波涅丁水平. 门德尔的随机化揭示了一个因果关系,即系统性硬化症的责任降低了皮质素,而不是相反.
科学领域:
- 内分泌学 在内分泌学.
- 类风湿病学 类风湿病学
- 遗传学 遗传学 是一个
背景情况:
- 之前对氨酸和全身性硬化症 (SSc) 的研究缺乏一致的发现和明确的因果关系.
- 作为一个关键的阿迪波金,阿迪波涅丁在炎症和新陈代谢中发挥作用,可能会影响SSc的发病性.
- 了解这种关系对于开发针对性治疗SSc.至关重要.
研究的目的:
- 进行更新的元分析,以评估循环中的阿迪波涅克丁和SSc.之间的关联.
- 通过使用孟德尔随机化来调查波涅丁水平和SSc风险之间的潜在因果关系.
主要方法:
- 在PubMed,Embase和Web of Science进行了系统的文献搜索,直到2024年9月.
- 超分析从观察性研究中汇集了数据,计算了标准化平均差异.
- 双向门德尔随机化利用全基因组关联研究总结统计数据推断因果关系.
主要成果:
- 对7项研究 (439例SSc病例) 的元分析显示,SSc患者的皮素减少 (SMD = -0.16,p=0.07),在扩散皮肤SSc (p=0.003) 中显著,但不限于皮肤SSc (p=0.81).
- 前进的门德尔随机化没有发现皮菌素对SSc风险的因果关系 (OR = 1.21,p=0.57).
- 反向门德尔随机化表明,对SSc的遗传责任对降低阿迪波内克丁水平 (β = -0.027,p=6.8E-06) 的因果关系.
结论:
- 观察数据证实系统性硬化症患者的阿迪波涅克水平较低.
- 门德尔的随机化确定了一种因果关系:对SSc的遗传倾向导致减少分.
- 需要对不同种群进行进一步的研究,以探索这些发现超越欧洲祖先.

The JAK-STAT Signaling Pathway
9.3K
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...

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.
