Abstract EN
MicroRNAs (miRNAs) regulate gene expression and at the same time mediate tumorigenesis.
miR-373-3p has diverse effects in tumors, but its role in tongue squamous cell carcinoma (TSCC) remains unknown.
The purpose of this study is to determine the function of miR-373-3p in the progression of TSCC.
Our results brought to light that miR-373-3p is markedly upregulated in clinical TSCC tissues compared with paired adjacent normal tissues and has significant correlation with a more aggressive TSCC phenotype in patients.
Gain-of-function and loss-of-function studies revealed that ectopic miR-373-3p overexpression promoted the metastasis of TSCC cells.
Notably, Wnt/β-catenin signaling was hyperactivated in TSCC cells overexpressing miR-373-3p, and this pathway was responsible for the epithelial-mesenchymal transition (EMT) induced by miR-373-3p.
Furthermore, miR-373-3p directly targeted and suppressed Dickkopf-1 (DKK1), a negative regulator of the Wnt/β-catenin signaling cascade.
These results demonstrate that, by directly targeting DKK1, miR-373-3p constitutively activated Wnt/β-catenin signaling, thus promoting the EMT-induced metastasis of TSCC.
Taken together, our findings reveal a new regulatory mechanism for miR-373-3p and suggest that miR-373-3p might be a potential target in TSCC therapy.
