Abstract
BACKGROUND
Hepatitis C virus (HCV) infection and its consequent complications are undeniably a public health burden worldwide, particularly in Egypt. Emerging evidence suggests that many lncRNAs have relevant roles in viral infections and antiviral responses.
AIM
To investigate the expression profiles of circulating lncRNAGAS5, lncRNAHEIH, lncRNABISPR and mRNABST2 in naïve, treated and relapsed HCV Egyptian patients, to elucidate relation to HCV infection and their efficacy as innovative biomarkers for the diagnosis and prognosis of HCV GT4.
METHODS
One hundred and thirty HCV-infected Egyptian patients and 20 healthy controls were included in this study. Serum lncRNAs and mRNABST2 were measured using quantitative real-time polymerase chain reaction (qRT-PCR).
RESULTS
Our results indicated that serum lncRNAGAS5 and LncRNABISPR were upregulated, whereas mRNA BST2 and LncRNA HEIH were downregulated in naïve patients. In contrast, HCV patients treated with sofosbuvir and simeprevir; with sofosbuvir and daclatasvir; or with sofosbuvir, daclatasvir and ribavirin exhibited lower levels of lncRNAGAS5 and lncRNABISPR with higher mRNABST2 compared to naïve patients. Notably, patients relapsed from sofosbuvir and simeprevir showed higher levels of these lncRNAs with lower mRNABST2 compared to treated patients. LncRNAGAS5 and lncRNABISPR were positively correlated with viral load and ALT at P < 0.001, whereas mRNABST2 was negatively correlated with viral load at P < 0.001 and ALT at P < 0.05. Interestingly, a significant positive correlation between lncRNA HEIH and AFP was observed at P < 0.001.
CONCLUSION
Differential expression of these RNAs suggests their involvement in HCV pathogenesis or antiviral response and highlights their promising roles in diagnosis and prognosis of HCV.
