Objective Our aim is to evaluate the expression of SATB 1 in human oral squamous cell carcinomas ( OSCC ) and its role in the invasiveness and metastasis of OSCC . Subjects and methods A human OSCC tissue microarray was used to evaluate the expression pattern of SATB 1. SATB 1 mRNA knockdown was performed in human OSCC cell lines SCC 25 and Cal27 to assess the function of SATB 1 in the invasiveness and metastasis of OSCC . Results SATB 1 is highly expressed in human OSCC determined by immunohistochemistry, and its nuclear/cytoplasmic ratio of histoscore is significantly correlated with patients’ prognosis. Reduced cell motility, invasiveness, expression of epithelial to mesenchymal transition ( EMT ) markers (N‐cadherin and β‐catenin), and elevated expression of epithelial markers were observed in SATB 1‐knockdown cells in in vitro studies. Depletion of SATB 1 also restored a cobblestone‐like morphology in TGF ‐β1‐treated cells. Conclusions These findings suggest SATB 1 may play an important role in OSCC invasiveness and metastasis.
