Background:
Liver transplantation and surgical resection are two major strategies for treatment of hepatocellular carcinoma (HCC) patients. One approach to treating HCC is the suppression of metastasis to other tissues. Herein, we aimed to study the effect of miR-4270 inhibitor on migration of HepG2 cells as well as activity of matrix metalloproteinase (MMP) these cells in order to find a strategy to suppress metastasis in future.
Methods:
HepG2 cells were treated with 0, 10, 20, 30, 40, 50, 60, 70, 80, and 90 nM of miR-4270 inhibitor, and then the cell viability was measured by trypan blue staining. Afterwards, cell migration and MMP activity of HepG2 cells were assessed by wound healing assay and zymography, respectively. The MMP gene expression was determined by real-time reverse transcription polymerase chain reaction.
Results:
Results showed that miR-4270 inhibitor decreased the cell viability of HepG2 cells in a concentration-dependent manner. Also, inhibition of the miR-4270 reduced invasion, MMP activity, and expression of MMP genes in HepG2 cells, respectively.
Conclusion:
Our findings suggest that miR-4270 inhibitor decreases in vitro migration, which could help find a new approach for HCC therapy patients.
Insights
Inhibiting miR-4270 in hepatocellular carcinoma (HCC) cells reduced their migration and matrix metalloproteinase (MMP) activity. This suggests miR-4270 inhibitors could be a novel strategy for suppressing HCC metastasis.

Main Methods:
- HepG2 cells were treated with varying concentrations of a miR-4270 inhibitor.
- Cell viability was determined using trypan blue staining.
- Cell migration, MMP activity, and MMP gene expression were analyzed via wound healing assay, zymography, and real-time RT-PCR, respectively.
Main Results:
- miR-4270 inhibitor decreased HepG2 cell viability in a dose-dependent manner.
- Inhibition of miR-4270 significantly reduced HepG2 cell invasion and MMP activity.
- Downregulation of MMP gene expression was observed following miR-4270 inhibition.
Conclusions:
