内分泌学在内分泌学.

背景情况:

观察性研究表明,胰岛素样生长因子-1 (IGF-1) 和帕金森病 (PD) 之间存在联系.
IGF-1水平与PD风险之间的因果关系尚不清楚.
影响IGF-1水平的遗传因素正在研究它们在PD中的作用.

研究的目的:

研究基因预测的IGF-1水平与帕金森病风险之间的潜在因果关系.
使用孟德尔随机化来评估IGF-1对PD的影响.

主要方法:

审查了全基因组关联研究 (GWAS),以确定与IGF-1和PD相关的单核酸多态 (SNP).
进行了两样本的门德尔随机化 (MR) 分析.
作为主要分析方法,采用了反变量加权 (IVW) 方法.

主要成果:

门德尔的随机化分析表明,较高的IGF-1水平与PD风险增加之间存在显著的关联 (OR,1.020;95% CI,1.003-1.038;p=0.0215).
统计测试 (MR-Egger截取) 表明,水平形不太可能偏向研究结果.

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...

EPS and iPS Cells in Disease Research

EPS and iPS Cells in Disease Research

Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
