miR-30a Serves as a Tumor Suppressor for Hepatocellular Carcinoma by Downregulating ADAMTS14
Background:
Hepatocellular carcinoma (HCC) is a very common malignancy in the world, but the effect of therapies on advanced HCC has not improved for decades. The present study aimed to investigate the role of miR-30a in the tumorigenesis of HCC.
Methods:
The expression of miR-30a and ADAMTS14 in HCC tissues were determined. Luciferase reporter gene detection confirmed the correlation between miR-30a and ADAMTS14. Cell viability and apoptosis rate were examined using an MTT assay and flow cytometry. Cell migration and invasion ability were detected by a transwell assay. The protein expression of ADAMTS14, β-catenin, GSK-3β, and p-GSK-3β were determined using western blotting.
Results:
miR-30a was negatively correlated with the expression of ADAMTS14 in HCC tissues. Further research confirmed that ADAMTS14 is the direct target of miR-30a. In addition, the expression of ADAMTS14, cell viability and apoptosis were suppressed by miR-30a overexpression, while knockdown of miR-30a led to the opposite result. miR-30a also inhibits the phosphorylation of GSK-3β and β-catenin, without changing the total GSK-3β level.
Conclusions:
miR-30a acts as a tumor suppressor in the progression of HCC and can be used as a biomarker for early prediction and diagnosis.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
