MiR-520b/HBXIP modulates growth of LO2-X-S cells in vivo. (A-G) The effect of miR-520b or si-HBXIP on the growth of LO2-X-S cells was detected by xenograft assay. The expression levels of miR-520b and HBXIP in the tumor tissues from mice (n = 5, each group) were determined by qRT-PCR or western blot analysis, respectively. Data are shown as mean ± SD of three independent experiments (*P < 0.05, **P < 0.01, Student’s t test). (H) A model of HBx accelerating hepatocarcinogenesis with partner survivin.
