Background  Based on our recent microarray analysis, we found that miR-145 was obviously downregulated in nasopharyngeal carcinoma (NPC) tissues. However, little is known about its function and mechanism involving in NPC development and progression.    Methods  Quantitative RT-PCR was used to detect miR-145 expression in NPC cell lines and clinical samples. Wound healing, Transwell migration and invasion, three-dimension spheroid invasion assays, and lung metastasis model were performed to test the migratory, invasive, and metastatic ability of NPC cells. Luciferase reporter assay, quantitative RT-PCR, and Western blotting were used to verify the target of miR-145.    Results  MiR-145 was obviously decreased in NPC cell lines and clinical samples ( P <0.01). Ectopic overexpression of miR-145 significantly inhibited the migratory and invasive ability of SUNE-1 and CNE-2 cells. In addition, stably overexpressing of miR-145 in SUNE-1 cells could remarkably restrain the formation of metastatic nodes in the lungs of mice. 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.    Conclusions  Our findings demonstrated that miR-145 function as a tumor suppressor in NPC development and progression via targeting  FSCN1 , which could sever as a potential novel therapeutic target for patients with NPC.
