Cure8 research brief
Alternative splicing appears to be a major, distinct source of transcriptomic change in IBD, which could affect understanding of disease mechanisms and biomarker development. Knowing that splicing and expression implicate different pathways may guide future research toward new targets or diagnostics.
Researchers, translational scientists, and clinicians interested in IBD molecular biology and biomarker discovery.
This preprint reports a transcriptome-wide study comparing gene expression (DE) and alternative splicing (DS) in colonic mucosal biopsies from Crohn’s disease (CD), ulcerative colitis (UC), and non-IBD controls.
The authors find many genes with differential splicing that are largely distinct from genes with differential expression, and they report pathway differences linked to splicing (for example, signaling and lipid metabolism) versus expression (chromatin, transcription, metabolic pathways).
The work highlights alternative splicing as a separate layer of molecular change in IBD and points to disease-subtype differences (CD vs UC) in splicing-enriched pathways such as extracellular vesicles in CD and ER-to-Golgi trafficking and stress-granule pathways in UC.

Identifying genes and pathways involved in IBD can point to new biological mechanisms, potential biomarkers, and future targets for research that may eventually inform diagnosis or treatment.
If validated, blood-based AI predictors of organ-specific aging might help flag organs aging faster in people with Crohn’s disease or other conditions, potentially enabling earlier monitoring or research into causes....
The work searches for shared blood-based gene signatures and biomarkers across HLA-B27–linked diseases (including Crohn’s disease and ulcerative colitis), which could point to common mechanisms or cross-disease...
