Figure 2. Up-regulation of miR-452 in HCC.

(A) The percentage of CD44+ and CD133+ cells markedly increased upon miR-452 up-regulation both in LM3 and Huh7. (B) MiR-452 overexpressed HCC cells showed higher chemoresistance to doxorubicin and sorafenib. (C) The self-renewal capability of LM3 and Huh7 was significantly enhanced after miR-452 expression increased in tumor sphere assay. (D) miR-452 efficiently promoted HCC invasion in vitro. (E) The capability of tumorigenicity significantly enhanced both in the primary and secondary xenograft model of LM3/miR-452 cells in comparison with LM3/NC cells. (F) In vivo metastasis assay, miR-452 distinctly aggravated the metastasis of LM3 cells (n = 5).
