Summary
MicroRNAs (miRNAs) are key regulators of gene expression implicated in inflammatory bowel disease (IBD). Research reveals distinct miRNA patterns in IBD subtypes, offering potential for new diagnostics and therapeutics.
Area of Science:
- Molecular Biology
- Genetics
- Immunology
Background:
- MicroRNAs (miRNAs) are small noncoding RNA molecules regulating gene expression.
- Gene expression dysregulation is linked to various diseases.
- miRNAs are increasingly recognized for their roles in disease pathophysiology.
Purpose of the Study:
- To review the role of miRNAs in the pathophysiology of inflammatory bowel disease (IBD).
- To evaluate miRNAs as potential biomarkers and therapeutic targets for IBD.
Main Methods:
- Review of recent studies on miRNA expression in IBD tissues and body fluids.
- Analysis of identified miRNA expression patterns in Crohn's disease and ulcerative colitis.
- Examination of miRNA-gene target networks in IBD.
Main Results:
- Unique miRNA expression patterns have been identified in IBD subtypes.
- These patterns may help distinguish between Crohn's disease and ulcerative colitis.
- Significant progress in understanding miRNA-gene interactions in IBD.
Conclusions:
- miRNAs show promise as biomarkers and therapeutic targets for IBD.
- Further research is needed to overcome challenges for clinical utility of miRNA-based diagnostics and therapeutics.

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

1.4K
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
722
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

4.2K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
