miR-106b promotes cancer progression in hepatitis B virus-associated hepatocellular carcinoma

Figure 2 The mRNA expression levels of the miR-106b-25 cluster and MCM7 in tumor and non-tumor regions of hepatitis B virus-associated hepatocellular carcinoma patients (n = 108). A: Schematic representation of the miR-106b-25 cluster of miRNA (miR-106b, miR-93 and miR-25) within the 13^th intron of the MCM7 gene. The yellow boxes represent pre-miRNAs. The blue boxes represent mature miRNAs; B-E: miR-106b (B), miR-93 (C), miR-25 (D), and MCM7 (E) expression levels in the tumor and non-tumor regions of hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) patients, determined using q-RT-PCR. ^bP < 0.001 NT vs T. a.u.: Arbitrary unit.
