Nasopharyngeal carcinoma (NPC) is a highly invasive malignancy with cervical
lymphopathy as the initial presentation. Epithelial?mesenchymal transition (EMT),
a process by which epithelial cells lose cell?cell adhesion and gain migratory
and invasive properties, has a pivotal role in metastasis. Forkhead box C1
(FoxC1), a member of the forkhead family of transcription factors, induces EMT
and has a critical role in metastasis of multiple human cancers. However, the
role of FoxC1 in the progression of NPC has remained elusive. The present study
revealed that the expression of FoxC1 was markedly elevated in NPC tissues
compared with that in chronically inflamed nasopharyngeal tissues and was closely
correlated with vimentin, fibronectin and N?cadherin expression as indicated by
immunohistochemical assays. In addition, high FoxC1 expression was positively
associated with lymph node metastasis, distant metastasis and an advanced
clinical stage in patients with NPC. Furthermore, FoxC1 expression was high in
NPC cell lines while being low in an immortalized normal nasopharyngeal
epithelial cell line. In vitro, knockdown of FoxC1 in the CNE2 human NPC cell
line by small interfering RNA downregulated vimentin, fibronectin and N?cadherin
expression and reduced the migratory and invasive capacity of CNE2 cells. In
conclusion, the present study indicated that FoxC1 has a pivotal role in EMT
through the upregulation of vimentin, fibronectin and N?cadherin expression.
Thus, FoxC1 may be a potential therapeutic target in NPC.
