Figure Lengend Snippet: Differential genes after overexpression and knockdown of TARBP2 in HepG2 cells. (A) Heatmaps represent the expression level of the whole genome (left) and showing the intersect of differentially expressed genes at 70% fold-change from two groups (right) respectively. (oe-Ctrl vs oe- TARBP2 , and sh-Ctrl vs sh- TARBP2 ). (B) A Venn Diagram of differentially expressed genes at the cut-off of 70% fold-change. Group-I, up-regulated genes from oe-Ctrl to oe- TARBP2 ; Group-II, down-regulated genes from oe-Ctrl to oe- TARBP2 ; Group-III, up-regulated genes from sh-Ctrl to sh- TARBP2 ; Group-IV, down-regulated genes from sh-Ctrl to sh- TARBP2 . (C) The KEGG pathways and GO biological processes enriched in the differentially expressed genes at 70% fold-change. (D) The mRNA expression levels of candidate genes from enriched pathway. (E) Relative expression levels of SERPINE1 in HCC tissues. (F) Correlation between the relative expression level of TARBP2 and SERPINE1 in HCC tissues. *p-value < 0.05.

Figure Lengend Snippet: SERPINE1 mRNA is a target of miRNA-145 linked to TARBP2 . (A) Flow chart of selection and analysis of potential miRNAs. (B) Levels of 4 potential miRNAs in the oe/sh- TARBP2 HepG2 cells. (C) Comparison of miR-145 expression between HCC tumors and tumor adjacent tissues (N = 20) (paired t-test p-value = 0.038). (D, E) miR-145 levels in HCC tumors are positively associated with TARBP2 (Pearson r = 0.47, p-value = 0.037) and negatively associated with SERPINE1 (Pearson r = -0.45, p-value = 0.049) (N=20). (F) The binding sites of miR-145 in the 3’-UTR of SERPINE1 mRNA. (G) The effects of miR-145 on reporters, pmirGLO- SERPINE1 -wild-type and pmirGLO- SERPINE1 -mutant, were measured by luciferase reporter assays in HepG2 cells. *p-value < 0.05; **p-value < 0.01; NS, no significance; NC, negative control.

Figure Lengend Snippet: A working model for the TARBP2-miR-145-SERPINE1 axis in HCC progression. The loss of TARBP2 induces the upregulation of SERPINE1 through reducing the processing of miR-145. This linear TARBP2-miR-145-SERPINE1 axis is involved in proliferation, migration, and invasion in HCC cells.
