Figure 2. Expression levels of miRNAs in serum of HCC patients, HBV patients without HCC and healthy subjects.

Figure 2

Levels of miR-122 (A), miR-222 (B), miR-223 (C) and miR-21 (D) were measured in serum of 48 HCC patients (n = 48), HBV patients without HCC (n = 48) and healthy subjects (n = 24) by RT-qPCR. Levels of miR-122 were significantly higher in HCC patients than disease controls (p<0.05) or healthy controls (p<0.001). Although levels of miR-222 and miR-223 were also significantly elevated in HCC patients than in healthy controls (p<0.05), no significant difference was observed for these two miRNAs between HBV subjects with and without HCC (p>0.05). Levels of miR-21 were reduced in HCC patients than in healthy controls (p<0.05), no significant difference was observed for miR-21 between HBV subjects with and without HCC (p>0.05).
