炎症性肠病(IBD)的一个主要挑战是整合不同的IBD数据集来构建IBD的预测模型。我们提出了一个IBD免疫成分的预测模型,该模型使用与IBD的细胞、组织和病理生理学相关的功能和调节注释,通过全基因组关联研究(GWAS)来告知先前与IBD相关的基因座之间的因果关系。我们的模型由单个网络组成,该网络使用从三个不同疾病阶段的IBD患者群体分离的肠道样本产生的分子数据构建。我们进行了关键驱动因素分析,以确定被预测为调节与IBD相关的网络调节状态的基因,对12个最主要的关键驱动因素进行了优先排序和前瞻性实验验证。这一经过验证的关键驱动程序集不仅引入了IBD核心过程的新调节器,还提供了可直接查询以询问和完善定义IBD的监管框架的遗传、分子和临床特征的集成电路。
A major challenge in inflammatory bowel disease (IBD) is the integration of diverse IBD data sets to construct predictive models of IBD. We present a predictive model of the immune component of IBD that informs causal relationships among loci previously linked to IBD through genome-wide association studies (GWAS) using functional and regulatory annotations that relate to the cells, tissues, and pathophysiology of IBD. Our model consists of individual networks constructed using molecular data generated from intestinal samples isolated from three populations of patients with IBD at different stages of disease. We performed key driver analysis to identify genes predicted to modulate network regulatory states associated with IBD, prioritizing and prospectively validating 12 of the top key drivers experimentally. This validated key driver set not only introduces new regulators of processes central to IBD but also provides the integrated circuits of genetic, molecular, and clinical traits that can be directly queried to interrogate and refine the regulatory framework defining IBD.
