Telomere length and telomerase reverse transcriptase mRNA expression in patients with hepatitis C

Area of Science:

• Molecular Biology
• Hepatology
• Oncology

Background:

• Shortened telomeres are indicators of genetic instability, potentially leading to aneuploidy and cancer.
• Chronic Hepatitis C virus (HCV) infection is a pre-neoplastic condition associated with hepatocellular carcinoma development.

Purpose of the Study:

• To evaluate telomere length and elongation in patients with different stages of HCV infection.
• To investigate the correlation between telomere length and HCV progression.

Main Methods:

• Analysis of peripheral lymphocytes from 10 chronic active HCV patients, 10 HCV remission patients, and 10 healthy controls.
• Measurement of human telomerase reverse transcriptase (hTERT) mRNA expression using RT-PCR.
• Telomere length analysis via Quantitative Fluorescence In Situ Hybridization (Q-FISH) and a novel computerized technique.

Main Results:

• Significantly decreased hTERT mRNA expression in active HCV patients and slightly decreased levels in remission patients compared to controls.
• Shorter telomere length observed in both chronic active HCV and remission patients relative to healthy individuals.

Conclusions:

• A correlation exists between telomerase reverse transcriptase mRNA expression and telomere length in various stages of HCV infection.
• These findings may indicate an increased risk of malignant transformation in HCV-infected patients.
