科学领域:
- 遗传学 是一个遗传学.
- 免疫学 免疫学 免疫学
- 分子生物学分子生物学
背景情况:
- 类风湿性关节炎 (RA) 是一种具有复杂遗传基础的自身免疫性疾病.
- 血管内皮生长因子A (VEGFA) 基因变异在RA易感性中的作用尚未完全理解.
- 之前对VEGFA基因变异和RA风险的研究已经产生了相互矛盾的结果.
研究的目的:
- 综合评估特定VEGFA基因变异与类风湿性关节炎 (RA) 风险之间的关联.
- 通过元分析来澄清VEGFA多态度和RA易感性之间的有争议的关系.

Genome-wide Association Studies-GWAS
13.3K
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
8.8K
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...

Single Nucleotide Polymorphisms-SNPs
15.0K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
