Objective
To investigate the role of serum microRNA (miR)-29s as biomarkers for disease progression in patients with chronic hepatitis B virus infection.
Methods
By using realtime quantitative polymerase chain reaction assay, we measured serum miR-29a/b/c levels in different groups of patients with chronic hepatitis B virus infection. We analyzed correlation of serum miR-29 levels with liver biochemistry, fibrosis and necroinflammation stage.
Results
Patients were divided by fibrosis stage into S0/1 (minimal fibrosis), S2/3 (progressing fibrosis) and S4 (cirrhosis). Serum miR-29a/c levels in S0/1 and S2/3 were significantly higher than those in S4 patients (P < 0.001), the difference between S0/1 and S2/3 patients was not significant. miR-29b levels were higher in S0/1 patients than other groups (P < 0.001), but not significantly different between S2/3 and S4. In fibrosis stage S0/1 and S2/3, patients with minimal liver inflammation (G0/1) tended to express higher miR-29 levels than advanced inflammation (G2-4), the difference was insignificant. All miR-29 members demonstrated significant correlation with ALT levels (P <0.05 for miR-29a, P <0.001 for miR-29b, P <0.01 for miR-29c) in S0-3 patients. Expression of miR-29s was highest in immune tolerant patients (P < 0.001).
Conclusions
Serum miR-29 levels negatively correlate with fibrosis and necroinflammation in patients with chronic hepatitis B virus infection. miR-29s appear to be novel biomarkers for predicting disease progression in these patients.
