The lack of noninvasive methods for assessment of the degree of liver damage is the main limitation in the clinical management of liver diseases. Aim: This study was conducted to evaluate the expression level of plasma miR-500 in HCV-induced fibrosis, cirrhosis and HCC patients. Methods and results: This prospective study involved 120 subjects, who were divided into 4 groups (n=30/group): healthy control, liver fibrosis patients, liver cirrhosis patients and HCC patients; all patients encountered in the work were clinically diagnosed as chronic HCV patients. The expression of miR-500 in plasma was asessed using quantitative real-time PCR, whereas serum alpha-fetoprotein (AFP) was measured using electrochemi-luminescence immunoassay. Results: The fold change in expression of plasma miR-500 showed significant up-regulation in cirrhotic patients more than 8 fold change as compared to fibrosis group. No significant fold changes in plasma miR-500 expression were found between either (HCC versus cirrhosis group) or (HCC versus fibrosis group. The serum level of AFP was 28.09 higher in the HCC group than non-HCC group.  Receiver operating characteristic curve (ROC) analysis indicated that the ideal cut-off values of the plasma miR-500 in both fibrosis and cirrhosis groups were 1.52 and 1.15, respectively and 8.2 and 4.55, respectively for AFP. Conclusion: Plasma miR-500 can be used as a novel biomarker for the differentiation between liver fibrosis and cirrhosis.
