- 遗传流行病学遗传流行病学
- 类风湿病学 类风湿病学
背景情况:
- 改变能量代谢与纤维性疾病有关.
- 系统性硬化症 (SSc) 患者可能从能量管理中受益.
- 基础代谢率 (BMR) 和SSc之间的因果关系尚不清楚.
研究的目的:
- 使用遗传数据调查BMR和SSc之间的因果关系.
- 为了确定BMR是否因果关系地影响SSc.的发展.
主要方法:
- 两个样本的孟德尔随机化 (MR) 分析.
- 利用了全基因组关联研究 (GWAS) 的总结统计数据.
- 使用逆方差加权 (IVW),MR-Egger和加权中位数 (WM) 方法与灵敏度分析.
主要成果:

Genome-wide Association Studies-GWAS
13.2K
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.

The JAK-STAT Signaling Pathway
8.7K
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...
