概括

遗传研究将ADAM19与人类肺功能联系起来. 鼠标模型显示Adam19缺乏影响肺机械和炎症,支持其在呼吸系统健康中的因果作用.

科学领域:

遗传学和肺部医学
呼吸系统研究中的动物模型

背景情况:

全基因组关联研究 (GWAS) 已经确定了550多个与人类肺功能相关的位置,但因果基因往往不清楚.
解体素和金属蛋白酶域19 (ADAM19) 中的单核酸多态性始终与人类GWAS中的肺功能有关.

研究的目的:

用小鼠模型研究Adam19在肺功能中的因果作用.
确定Adam19缺陷在呼吸系统中的生理和分子后果.

主要方法:

生成并验证了一个Adam19淘汰赛 (KO) 鼠标模型.

评估呼吸道炎症和对刺激的反应 (甲荷林,LPS).

主要成果:

亚当19 KO小鼠表现出体重,骨矿物质含量和肺机械的改变,包括呼吸系统弹性降低和FEV0.1和FVC增加.
在暴露于LPS后,KO小鼠对甲胆的反应减弱,中性粒细胞扩散减少.
RNA-Seq在KO肺部中鉴定出差异表达的基因,对TNF通路进行负丰富.

结论:

鼠的研究结果支持ADAM19在调节肺功能中的因果作用.
ADAM19影响呼吸系统机制,呼吸道炎症和对炎症刺激的反应.

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...
