- W4385653670 abstract "Background: Hepatitis C virus (HCV) has the ability to change cellular messenger RNA transcription and translation by stimulating the synthesis of cellular microRNAs (miRNAs) that impair immune response and facilitate viral reproduction. One of the most important members of the immune response against HCV is nuclear factor-kappa B (NF-κB), which is regulated by cellular miRNAs. Aims: we aimed to investigate the correlation of NF-κB serum level with circulatory miRNA-221 (miR-221) fold change in HCV-exposed individuals. Materials and Methods: Serum level of NF-κB in 88 samples (22 patients with persistent HCV infection, 22 individuals with spontaneous HCV virus clearance, 22 individuals treated with direct-acting antivirals (DAAs) drugs, and 22 uninfected apparently healthy blood donors as control) was measured by enzyme-linked immunosorbent assay. Reverse transcriptase–polymerase chain reaction was used to quantify the expression fold of circulatory miR-221. Results: The results showed that there was a significant decrease in the mean level of NF-κB at P < 0.000 among HCV-exposed patients (2.0058 ng/ml) as compared to the control group (2.9841 ng/ml). The mean fold change of miR-221 was significantly upregulated about six more times among HCV-exposed patients (mean = 6.3545) compared to the control group (mean = 1.1864). Furthermore, the mean ± standard deviation of miR-221 fold change in patients with persistent HCV infection was significantly higher compared to patients cured after DAA therapy (P = 0.048), there was a weak negative correlation (r = −0.246, P = 0.021) between NF-κB serum level and miR-221 folding level. Conclusion: HCV infection disrupts NF-κB activation, resulting in dysregulation of miR-221 that persists long after the virus has been cleared. Thus, quantification of serum NF-κB and miR-221in HCV-exposed patients could be used as noninvasive prognostic marker during long-term follow-up. Furthermore, a miRNAs profile analysis can help distinguish HCV-exposed from healthy individuals." @default.
