Overexpression of FGFR1 in TSCC was related to poor differentiation and metastasis.
The expression of FGFR1 enhanced the metastatic capability of TSCC cells.
The expression of FGFR1 prevented the EMT phenotype in TSCC cells in vitro.
FGF1–FGFR1 axis promotes the TSCC metastasis through the EMT pathway.
