Severity of fibrosis was determined by both histologic staging using the METAVIR scoring system and noninvasive transient elastography. Following RNAisolation, expression levels of mi R-21, mi R-122, mi R-214, mi R-221, mi R-222, and mi R-224 were determined using Taq Man Micro RNA Assays applying mi R-140 as the reference. Selection of mi RNAs was based on their characteristic up- or downregulation observed in hepatocellular carcinoma. Relative expression of mi RNAs was correlated with fibrosis stage and liver stiffness(LS) value measured by transient elastography, as well as with serum alanine aminotransferase(ALT) level.RESULTS: The expression of individual mi RNAs showed deregulated patterns in stages F1-F4 as compared with stage F0, but only the reduced level of mi R-122 in stage F4 was statistically significant(P < 0.04). When analyzing mi RNA expression in relation to fibrosis, levels of mi R-122 and mi R-221 showed negative correlations with fibrosis stage, and mi R-122 was found to correlate negatively and mi R-224 positively with LS values(all P < 0.05). ALT levels displayed a positive correlation with mi R-21(P < 0.04). Negative correlations were observed in the fibrosis samples of mixed etiology between mi R-122 and fibrosis stage and LS values(P < 0.05), and in the samples of chronic viral hepatitis, between mi R-221 and fibrosis stage(P < 0.01), whereas mi R-21 showed positive correlation with ALT values in the samples of autoimmune liver diseases(P < 0.03). The results also revealed a strong correlation between fibrosis stage and LS values(P < 0.01) when etiology of fibrosis was not taken into account.CONCLUSION: Reduced expression of mi R-122 in advanced fibrosis and its correlation with fibrosis stage and LS values seem to be characteristic of hepatic fibrosis of various etiologies.展开更多
