Patient-Specific Regulatory Network Rewiring in Inflammatory Bowel Disease: How Genetic Polymorphisms Divert Incoming Signals and Contribute to Disease Pathogenesis.
Article in Inflammatory bowel diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIntestinal cells receive incoming signals from neighboring cells and microbial communities. Upstream signaling pathways transduce these signals to reach transcription factors (TFs) that regulate gene expression. In inflammatory bowel disease (IBD), most single nucleotide polymorphisms (SNPs) are in non-coding genomic regions containing TF binding sites. These SNPs can alter TF binding affinity, leading to regulatory shifts: TFs may lose or gain binding sites, causing a significant rewiring of the incoming signals regulating gene expression. Understanding this rewiring offers critical insights into the cellular mechanisms driving IBD pathogenesis.
methodsTo investigate this rewiring, we developed a systems genomics pipeline and analyzed individual genotype data from 2636 IBD patients to infer the incoming signals affecting patient-specific gene regulatory networks. Our in silico approach predicted changes in the repertoire of TFs binding to genomic loci due to IBD-associated non-coding SNPs in each patient compared to healthy controls. By functionally annotating the TFs in disease and healthy states, we highlighted the rewiring of upstream signaling pathways that may arise due to IBD-associated SNPs.
resultsWe revealed that diverse non-coding SNP combinations in IBD patients lead to functional switches from healthy signals to disease-associated signals, capturing patient heterogeneity while uncovering common upstream regulators driving disease pathogenesis. Notably, rewired incoming signals belonged to key functional processes such as pro-inflammatory immune responses, epithelial barrier dysfunction, stress responses, wound healing, and antimicrobial defense pathways.
conclusionsIn summary, this work highlights the importance of personalized investigation of signaling processes upstream of genetic polymorphisms to gain a more comprehensive understanding of IBD pathogenesis.
