科学领域:

免疫学和分子生物学
基因组学和生物信息学

背景情况:

区分骨关节炎 (OA) 和类风湿性关节炎 (RA) 对于有效治疗至关重要.
导致OA和RA的炎症分子机制需要进一步调查,以确定可靠的诊断生物标志物.

研究的目的:

为了比较OA和RA之间的炎症分子机制.
确定新的分子生物标志物,以准确诊断RA与OA.

主要方法:

从基因表达总量 (GEO) 中获取和分析微阵列数据集 (GSE55235,GSE100786).
使用GEO2R进行差异基因表达分析,其次是基因本体学 (GO) 和途径分析 (PANTHER,Enrichr).
使用接收器操作特征 (ROC) 曲线分析验证潜在的生物标志物.

主要成果:

与对照组相比,在OA中鉴定了2129个差异表达基因 (DEG),在RA中鉴定了2494个DEG.
发现了在RA中独特丰富的Th1和Th2细胞分化的途径.
确定了HLA-DQA1的下调和MAPK8IP3的上调,作为区分RA和OA的可靠生物标志物.

结论:

基因表达的改变,特别是Th1/Th2细胞分化途径中的基因表达改变,为RA诊断提供了新型分子生物标志物的潜力.
已识别的生物标志物HLA-DQA1和MAPK8IP3可以帮助在临床环境中区分RA和OA.

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...

DNA Microarrays

DNA Microarrays

Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...
