HCV recurrence after liver transplantation is one of the causal agents for graft rejection. This study aims to profile non-invasive biomarkers in patients with HCC who had liver transplants. One hundred participants were categorized into three groups (20 control, 32 recurrent HCV (RHCV), and 48 non-RHCV). The expression of six miRNAs (hsa-miR-124-3p, hsa-miR-155-5p, hsa-miR-205-5p, hsa-miR-499a-5p, hsa-miR-574-3p, and hsa-miR-103a-3p) and two mRNAs IL-1β, STAT1 were quantified. RHCV group has higher levels of hsa-miR-574-3p and hsa-miR-155-5p and lesser levels of hsa-miR-499a-5p than control groups (p = 0.024, 0.0001, 0.002; respectively). RHCV and non-RHCV groups revealed a significant reduction in levels of IL-1β and STAT1 mRNA compared to the control (p = 0.011, 0.014; respectively). According to ROC analysis, miR-155-5p can differentiate among the patients' groups, while miR-574-3p, IL-1β, and STAT1 mRNA can discriminate between RHCV and control groups. In conclusion, RHCV patients have dysregulated expression of five transcripts compared to non-RHCV and control groups.
