Fig. 5: LncRNA CERS6-AS1 upregulates MDM2 via sponging to miR-30b-3p.

A Venn analysis screened 14 potential target genes of miR-30b-3p. B The mRNA expression levels of these potential target genes was measured by PCR analysis. The correlation between CERS6-AS1 and MDM2 (C) or BCL9L (D) was evaluated based on TCGA database. E, F The relative mRNA and protein expression of MDM2 in miR-30b-3p mimics group and negative group. G The binding site between miR-30b-3p and MDM2. H Luciferase assay was performed to detect the direct interaction between MDM2 and miR-30b-3p. I-K The expression of MDM2 in HCC tumors and normal tissues based on individual cancer stage or grade from TCGA database, normal tissues regard as control group. L The expression of MDM2 in HCC tissues was measured by PCR analysis. M Pearson correlation analysis was performed to evaluate the correlation between miR-30b-3p and MDM2. N The correlation between MDM2 and CERS6-AS1 was evaluated via Pearson correlation analysis. All experiments included were repeated at least three times, *p < 0.05, **p < 0.01, ***p < 0.001.
