Fig. 2 Correlations of serum miRNA-125b with liver necroinflammation and fibrosis. (a) Serum miRNA-125b levels in patients with hepatitis B virus (HBV) infection and healthy controls. (b) Distribution of serum miRNA-125b levels in patients at different phases of the course of chronic hepatitis B (CHB) infection. (c, d) Patients were divided into groups by grading of necroinflammation or staging of fibrosis or both. Abbreviations: miRNA, microRNA; HBV, hepatitis B virus; HC, healthy control; IT, immune-tolerant; IR, immune-reactive; IC, inactive carrier; ENH, hepatitis B e antigen negative chronic hepatitis B; G, grading of necroinflammation; S, staging of fibrosis; n, number.

Fig. 3 Differentiating power of serum alanine transaminase (ALT), miRNA-125b, miRNA-124 and combined miRNA-125b and miRNA-124 for liver necroinflammation severity in patients with chronic hepatitis B (CHB). (a) Receiver operating characteristic curves and area under the curves (AUC) are presented for ALT, miRNA-125b, miRNA-124 and the combination of miRNA-125b and miRNA-124 for differentiating the severity of liver necroinflammation in patients with CHB (n = 138) from healthy controls (HCs; n = 35). (b) Moderate-to-severe necroinflammation (≥G2) in patients with normal ALT (≤50 U/L; n = 59) and (c) in patients with ALT <100 U/L (n = 80).

Fig. 4 miRNA-125b enhanced hepatitis B virus (HBV) replication capacity in vitro. (a) HepG2.2.15 cells were transfected with step-increased levels of miRNA-125b mimic. Cells were harvested and intracellular, encapsulated HBV DNA was extracted and analysed by Southern blot analysis. (b) Supernatant hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) levels of HepG2.2.15 cells were determined by specific ELISAs after transfection with indicated doses of miRNA-125b mimic. (c) Functional effectiveness experiment of miRNA-125b on gene enhancer of zeste homologue 2. Abbreviations: miRNA, microRNA; HBV, hepatitis B virus; HBeAg, hepatitis B e antigen; HBsAg, hepatitis B surface antigen; EZH2, enhancer of zeste homologue 2.

FIG. S2 Serum miRNA-125b levels and liver histology of patients with chronic hepatitis B (CHB) before and after antiviral therapy (n = 29). (a) Changes in the proportion of necroinflammation (G0–4) and fibrosis (S0–4). (b) Serum miRNA-125 levels of patients with CHB before and after antiviral therapy.

FIG. S3 HepG2.2.15 cells were transfected with miRNA control (10 nM), miRNA-1 (5 nM) and miRNA-125b (5 nM). Cells were harvested and the levels of hepatitis B virus (HBV) replicative intermediates were determined by Southern blot as previous reported prevously [9].
