Conclusion
Oncogene miR-18a-5p accelerates malignant phenotype by suppressing CPEB3. MiR-18a-5p/CPEB3 axis in HCC identified in this study provides a new target for HCC treatment.
Methods
Differentially expressed miRNAs and mRNAs were acquired by bioinformatics analysis. qRT-PCR was used for miR-18a-5p and CPEB3 mRNA expression detection. Cell functional assays were implemented to examine the biological functions of HCC cells. The binding relationship between miR-18a-5p and CPEB3 was verified by a dual luciferase assay.
Objective
To explore the function of the miR-18a-5p/CPEB3 axis in regulating the occurrence of hepatocellular carcinoma (HCC).
Results
In HCC, miR-18a-5p was remarkably highly expressed, while CPEB3 was markedly lowly expressed. HCC cell progression was facilitated after cells transfecting miR-18a-5p mimic, whereas silencing miR-18a-5p caused the opposite result. Overexpressing CPEB3 could restore promoting effect of miR-18a-5p on the growth of HCC cells.
