Nasopharyngeal carcinoma (NPC) is a common disease in Southern China with high prevalence. miR-944 has been reported to play a vital role in progression of a variety of cancers. The present study aimed to investigate the potential role of miR-944 in NPC cell migration and invasion through elucidating the interaction with its target genes, MACC1. Expression of miR-944 in NPC tissues and cell lines was examined with quantitative RT-PCR. Over-expressed miR-944 and suppressed miR-944 were established with miR-944 mimics and miR-944 inhibitor, respectively. The effect of miR-944 on cell migration and invasion was determined using Transwell cell migration and Matrigel invasion assay. Luciferase assay was used to determine the target of miR-944. Knocked down of MACC1 was done by MACC1 siRNA. Expression of MET related-markers was examined using Western blot analysis. The expression level of miR-944 was downregulated in NPC tissues and cell lines. Overexpression of miR-944 significantly inhibited the cell migration and invasion in NPC 6-10B cells. In contrast, suppression of miR-944 promoted cell migration and invasion in NPC C-6661 cells. MACC1 is a direct target of miR-944. MACC1 expression was repressed in miR-944 mimic transfected cells while it was enhanced in miR-944 inhibitor transfected cells. MACC1 knock down inhibited cell migration and invasion. Either miR-944 restoration or MACC1 knockdown caused enhanced E-cadherin, reduced N-cadherin, and vimentin expression. In conclusion, miR-944 could inhibit MET and metastasis of NPC by targeting MACC1. This study suggests that miR-944 has anti-tumor and anti-metastatic properties and could thus be a novel therapeutic agent for NPC treatment.
