Abstract |
Background |
Aberrant expression of miRNAs was involved in tumor initiation, progression and metastasis in multiple cancers. Many kinds of microRNAs in esophageal squamous cell carcinoma (ESCC) have been researched, whereas miR-30c has not been included.
Methods |
Firstly, we explored the expression of miR-30c in ESCC tissue and serum samples and its relations to the survival. To further investigate its effects on ESCC cells, we completed a series of experiments. We detected the effects of ectopic miR-30c expression on the proliferation, migration and invasion of ESCC cells in vitro. We identified the target role of SNAI1 in ESCC using Dual-luciferase reporter assay and western blot assay.
Results |
The results showed miR-30c was significant down-regulated in ESCC tissues and cell lines. Clinically, we found lower miR-30c expression was significantly correlated with worse ESCC progression and survival. Also we clarified that miR-30c suppressed cell proliferation, invasion and epithelial to mesenchymal transition (EMT) of ESCC cell lines. What's more, we figured out that miR-30c inhibits ESCC biological behaviors and EMT progress by directly binding to the 3′-UTR of SNAI1.
Conclusion |
This study provides new insight into the mechanism responsible for the development of human ESCC. Therefore, miR-30c could be a promising biomarker and a therapeutic target for ESCC in the future.
