Abstract:
A common and important problem in patients with chronic hepatitis B is the progression of liver fibrosis. Matrix metalloproteinases (MMPs) play an important role in the progression of liver fibrosis. Our aim of this study was to examine the association of MMP-3 polymorphism with liver cirrhosis in Korean patients with chronic hepatitis B. Genomic DNA was extracted from 127 patients with chronic hepatitis B (CHB), 92 patients with hepatitis B virus (HBV)-related liver cirrhosis (HBV-LC), and 146 healthy subjects. MMP-3 polymorphism was determined by polymerase-chain reaction-based assays, and the association with the progression of liver cirrhosis was investigated. With regard to MMP-3 polymorphism, there was no statistical difference in genotype distributions among the three groups. However, the peripheral platelet count of the 5A carriers was significantly lower than that of the 6A homozygotes in the HBV-LV group (85.0 +/- 36.9 vs. 109.8 +/- 47.0 x 10(9)/l; P = 0.02). With MMP-3 promoter polymorphism (rs3025058), a lower peripheral blood platelet count, which was related to advanced liver cirrhosis, was observed in 5A carriers. Therefore, more studies of MMP-3 gene polymorphism with larger populations should be conducted to further understand its role in the progression of liver cirrhosis.
Insights
Matrix metalloproteinase-3 (MMP-3) gene polymorphism may influence liver fibrosis progression in chronic hepatitis B. Lower platelet counts were observed in MMP-3 5A allele carriers, suggesting a potential role in liver cirrhosis development.
Area of Science:
- Hepatology
- Genetics
- Immunology
Background:
- Liver fibrosis progression is a significant complication in chronic hepatitis B (CHB) patients.
- Matrix metalloproteinases (MMPs), particularly MMP-3, are implicated in the pathogenesis of liver fibrosis.
- Understanding genetic factors influencing fibrosis progression is crucial for patient management.
Purpose of the Study:
- To investigate the association between MMP-3 gene polymorphism and liver cirrhosis in Korean patients with CHB.
- To explore the relationship between MMP-3 genotypes and clinical parameters, such as platelet count, in CHB patients.
Main Methods:
- Genomic DNA was collected from 127 CHB patients, 92 with hepatitis B virus (HBV)-related liver cirrhosis (HBV-LC), and 146 healthy controls.
- MMP-3 polymorphism was analyzed using polymerase-chain reaction (PCR)-based assays.
- Statistical analyses were performed to compare genotype distributions and clinical parameters among the groups.
Main Results:
- No significant differences in MMP-3 genotype distributions were found among the CHB, HBV-LC, and healthy control groups.
- A statistically significant lower peripheral platelet count was observed in MMP-3 5A allele carriers compared to 6A homozygotes within the HBV-LC group (P = 0.02).
- MMP-3 promoter polymorphism (rs3025058) was associated with lower platelet counts in 5A carriers, correlating with advanced liver cirrhosis.
Conclusions:
- MMP-3 gene polymorphism, specifically the 5A allele, may be associated with reduced platelet counts in HBV-related liver cirrhosis patients.
- This finding suggests a potential role for MMP-3 polymorphism in the progression of liver cirrhosis.
- Further research with larger cohorts is warranted to elucidate the precise role of MMP-3 gene polymorphism in liver fibrosis progression in CHB.
