Furthermore, fascin actin-bundling protein 1 (FSCN1) was verified as a target of miR-145, and silencing FSCN1 with small RNA interfering RNA could suppress NPC cell migration and invasion.
In this study, the biological function, molecular mechanism, and direct target genes of miR-145 in nasopharyngeal carcinoma (NPC) cells were investigated.
Taken together, our findings indicate that miR-145 is a tumour suppressor that affects invasive and metastatic properties of NPC via the miR-145/Smad3 axis, leading us to propose that miR-145 overexpression might be a potential therapeutic strategy of NPC intervention.
