Tissue-based Gene Expression as Potential Biomarkers for IBD Course

Area of Science:

• Gastroenterology
• Molecular Biology
• Genomics

Background:

• Inflammatory bowel diseases (IBD) exhibit significant heterogeneity in clinical presentation, disease behavior, and therapeutic response.
• Current diagnostic and therapeutic strategies rely on clinical, endoscopic, and histopathologic assessments, which often fail to predict durable remission.
• This limitation may stem from unaddressed disease pathogenicity heterogeneity not captured by existing classification systems.

Purpose of the Study:

• To review studies utilizing gut tissue-based gene expression profiles for predicting IBD disease outcomes.
• To highlight the potential of high-throughput sequencing to dissect disease heterogeneity and guide treatment selection.

Main Methods:

• Analysis of gut tissue-based gene expression profiles.
• Application of high-throughput sequencing approaches to mucosal biopsy samples.
• Review of existing literature on gene expression profiling in IBD.

Main Results:

• Gene expression profiling reveals a wide range of host gene expression in the gut lining.
• These molecular insights can better differentiate disease heterogeneity compared to traditional methods.
• Studies reviewed demonstrate the utility of gene expression data in predicting treatment response.

Conclusions:

• Gut tissue-based gene expression analysis represents a promising tool for personalized medicine in IBD.
• This approach can improve the prediction of disease outcomes and optimize therapeutic strategies.
• Leveraging existing biopsy samples with advanced sequencing offers a practical method to enhance IBD management.
