概括

这项研究确定了四个关键的突生物标志物 (ZBTB16,TNFSF11,SCRG1,KDELR3) 用于骨关节炎 (OA) 诊断. 这些生物标志物与免疫细胞相关,形成用于预测OA的机器学习模型.

科学领域:

发现生物标志物的发现.
基因组学就是基因组学.
免疫学免疫学免疫学

背景情况:

骨关节炎 (OA) 是一种普遍的关节疾病,缺乏有效的诊断生物标志物.
同位体生物标志物对于了解骨关节炎的发病和进展至关重要.

研究的目的:

确定骨关节炎 (OA) 的关键突生物标志物 (枢纽基因).
分析这些生物标志物与OA中的免疫细胞透之间的相关性.
开发一种用于预测OA的诊断模型.

主要方法:

使用基因表达综合 (GEO) 数据用于OA和健康的突样本.
使用权重基因共同表达网络分析 (WGCNA),LASSO,SVM-RFE和随机森林 (RF) 来识别枢纽基因.
开发了一种诊断名录,并使用ROC曲线和qRT-PCR验证了枢纽基因表达.
使用单样样本基因组丰富分析 (ssGSEA) 分析了免疫细胞透.

主要成果:

确定了四个枢纽基因 (ZBTB16,TNFSF11,SCRG1,KDELR3) 作为潜在的OA生物标志物.
发现了这些枢纽基因与调节性T细胞和自然杀手细胞之间的显著相关性.
在实验和验证数据集中确认了枢纽基因的异常表达.

结论:

一个用于OA诊断的机器学习模型是使用来自突组织的ZBTB16,TNFSF11,SCRG1和KDELR3构建的.
这些发现为OA诊断和治疗目标提供了基础.

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...
