Although matrix metalloproteinase 14 (MMP-14) has been shown to play a substantial role in the carcinogenesis of some types of cancer, its involvement in the pathogenesis of nasopharyngeal carcinoma (NPC) has not been reported. Here, we analyzed MMP-14 levels in the NPC specimens from patients and compared with the paired normal nasopharynx (NNP) tissues. We found that NPC had significantly higher messenger RNA (mRNA) and protein levels of MMP-14. Moreover, higher levels of MMP-14 correlated with more advanced status of clinical stage and lymphatic metastasis. In vitro, MMP-14 levels determined the potential of invasiveness of NPC cells, possibly through induction of EMT-associated genes. Our data thus highlight MMP-14 as a novel therapeutic target for NPC.
