Background:
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) characterized by persistent inflammation and tissue remodeling. Matrix metalloproteinases (MMPs) play a key role in extracellular matrix degradation, and their dysregulation is implicated in IBD. However, the specific role of membrane-type MMPs (MT-MMPs) in UC remains underexplored. This study investigates the expression of MT-MMPs in UC patients, including new cases and treatment-resistant patients, and evaluates their expression patterns compared to healthy people.
Methods And Results:
Colon biopsy samples were collected from three groups: healthy controls (n = 20), newly diagnosed UC patients (n = 20), and UC patients resistant to standard treatments (n = 20). The mRNA expression levels of MT-MMPs were assessed using quantitative real-time PCR. Receiver operating characteristic (ROC) curve analysis was performed to determine the diagnostic utility of these MT-MMPs. Correlation analysis was also conducted to explore the relationship between MT-MMPs and inflammatory markers (CRP, ESR) and vitamin D levels. Out of 6 members of MT-MMPs, MT2-MMP, and MT5-MMP were significantly downregulated in new cases and resistant UC patients compared to controls (P < 0.0001). ROC analysis demonstrated high sensitivity and specificity for MT2-MMP and MT5-MMP in differentiating UC patients from healthy individuals. Additionally, MT2,5-MMP expression was negatively correlated with CRP, ESR, and vitamin D levels, indicating their possible modulation of systematic inflammation.
Conclusion:
MT2-MMP and MT5-MMP are downregulated in UC and may serve as diagnostic biomarkers for disease severity. The findings highlight the need for further investigation into their therapeutic potential in modulating inflammation and tissue remodeling in UC.
Insights
Matrix metalloproteinases (MMPs), specifically MT2-MMP and MT5-MMP, are significantly downregulated in ulcerative colitis (UC) patients. These MMPs show potential as diagnostic biomarkers for UC severity and inflammation.
Area of Science:
- Gastroenterology
- Molecular Biology
- Biomarker Discovery
Background:
- Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) involving persistent inflammation and tissue remodeling.
- Dysregulation of matrix metalloproteinases (MMPs) is implicated in IBD pathogenesis.
- The role of membrane-type MMPs (MT-MMPs) in UC requires further elucidation.
Purpose of the Study:
- To investigate the expression patterns of MT-MMPs in UC patients, including new and treatment-resistant cases.
- To evaluate MT-MMPs as potential diagnostic biomarkers for UC.
- To explore the correlation between MT-MMP expression and inflammatory markers and vitamin D levels.
Main Methods:
- Colon biopsy samples from healthy controls (n=20), new UC cases (n=20), and treatment-resistant UC patients (n=20) were analyzed.
- Quantitative real-time PCR was used to measure mRNA expression levels of MT-MMPs.
- Receiver operating characteristic (ROC) curve analysis and correlation analysis were performed.
Main Results:
- MT2-MMP and MT5-MMP mRNA levels were significantly downregulated in both new and resistant UC patients compared to healthy controls (P<0.0001).
- ROC analysis confirmed high diagnostic utility for MT2-MMP and MT5-MMP in distinguishing UC patients.
- Downregulated MT2,5-MMP expression correlated negatively with C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and vitamin D levels.
Conclusions:
- MT2-MMP and MT5-MMP are downregulated in UC, suggesting their potential as diagnostic biomarkers for disease severity.
- These findings underscore the need for further research into the therapeutic potential of MT2-MMP and MT5-MMP in managing UC inflammation and tissue remodeling.

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...
