MiR-128-3p inhibits the proliferation, migration and invasion of human nasopharyngeal carcinoma cells via EMT
Abstract
Purpose: To investigate the effect of overexpressing miR-128-3p on the migration, invasion, and proliferation of human nasopharyngeal cancer cells, and associated pathways.
Methods: Cell counting kit-8 (CCK-8) and clone creation tests were used to investigate the effect of miR-128-3p inhibitor on the growth of C666-1 cells. The inhibitor control and miR-128-3p inhibitor were transfected into human nasopharyngeal cancer cells (C666-1) and allowed to incubate for 48 h. Cell migration and invasion assays were conducted using Transwell and Scratch assays. Cell cycle was assessed using propidium iodide (PI) single-staining method, while expression of miR-128-3p was evaluated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Expression levels of vimentin, E-cadherin, and N-cadherin were determined by Western blot.
Results: MiR-128-3p inhibitor transfection in C666-1 cells significantly increased cell proliferation, cell viability, and clonal proliferation, and also significantly reduced miR-128-3p expression levels, and enhanced cell migration and invasion. In C666-1 cells, inhibition of miR-128-3p induced epithelial mesenchymal transition (EMT).
Conclusion: MiR-128-3p inhibits nasopharyngeal cancer cells from proliferating, migrating, and invading by regulating epithelial mesenchymal transition. MiR-128-3p may therefore be a viable therapeutic target for nasopharyngeal cancer. Future studies are required to yield pertinent data in support of this hypothesis.
