Circular RNAs (circRNAs) are key regulators of intestinal epithelial homeostasis and gut diseases. This review highlights their roles and potential as biomarkers and therapeutic targets.
Area of Science:
- Gastroenterology
- Molecular Biology
- RNA Biology
Background:
- The intestinal epithelium is a rapidly self-renewing tissue crucial for host-environment interaction.
- Maintaining intestinal homeostasis involves coordinated cellular processes like proliferation, migration, and differentiation.
- Circular RNAs (circRNAs) are emerging as vital regulators in intestinal epithelial biology and pathology.
Purpose of the Study:
- To review the pathobiological functions and regulatory mechanisms of intestinal epithelium-enriched circRNAs.
- To highlight specific circRNAs like circHIPK3, Cdr1as, and circPABPN1.
- To discuss the clinical potential of circRNAs in gut diseases.
Main Methods:
- Literature review of studies on circRNAs in intestinal epithelium.
- Analysis of circRNA mechanisms, including interactions with microRNAs and RNA-binding proteins.
- Focus on specific circRNAs implicated in gut homeostasis and disease.
Main Results:
- CircRNAs are stable regulatory molecules involved in intestinal mucosa growth, regeneration, and barrier function.
- Dysregulated circRNAs are linked to inflammatory bowel disease and malignancies.
- Specific circRNAs (circHIPK3, Cdr1as, circPABPN1) play significant roles in intestinal epithelium.
Conclusions:
- CircRNAs are critical players in intestinal epithelial homeostasis and disease pathogenesis.
- CircRNAs hold promise as diagnostic biomarkers and therapeutic targets for gastrointestinal disorders.
- Further research into circRNA mechanisms can advance clinical applications in gut health.
