结合遗传和蛋白质基因风险得分可以改善炎症性肠病 (IBD) 的预测. 蛋白质组风险评分 (ProRS) 提供时间敏感的见解,而多基因风险评分 (PRS) 对IBD增加了长期价值.
科学领域:
- 遗传学和基因组学 遗传学和基因组学
- 蛋白质组学是指蛋白质组学.
- 生物标志物发现发现
背景情况:
- 炎症性肠病 (IBD),包括克罗恩病 (CD) 和性结肠炎 (UC),具有复杂的遗传和环境影响.
- 目前IBD多基因风险评分 (PRS) 的预测准确性有限,无法预测症状发病时间.
- 蛋白质组学分析提供了一种非侵入性方法来评估疾病状态并制定蛋白质组学风险评分 (ProRS).
研究的目的:
- 评估PRS和ProRS的预测能力,单独和组合,对IBD风险.
- 开发和评估CD和UC的ProRS模型,包括它们随着时间推移的表现.
- 研究将遗传和蛋白质组数据整合到IBD风险分层中的协同效益.
主要方法:
- 利用了来自51,772个人的英国生物库数据.
- 开发了用于CD和UC的ProRS模型.
- 评估了PRS,ProRS和它们的组合随时间推移的预测性能.
主要成果:
- 整合PRS和ProRS显著改善了IBD发病率预测.
- ProRS提供了时间敏感的风险预测,而PRS提供了长期预测价值.
- 在高PRS的个体中,ProRS表现出增强的预测性能.
结论:
- 将遗传和蛋白质组数据结合起来,代表了一种加强IBD风险预测的强大方法.
- 多原子数据集成对推进IBD精准医学具有重大潜力.
- ProRS为IBD风险评估提供了一种新的,时间敏感的生物标志物.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
