Recent studies have demonstrated the clinical significance of MTSS1 in certain type of cancers yet the clinical relevance of MTSS1 in oesophageal squamous cell carcinoma ESCC has not been reported. Methods In this study we assessed the expression levels of MTSS1 in tumours and its matched adjacent nontumour tissues obtained from 105 ESCC patients. We also used ESCC cells with differing MTSS1 expression and assessed the influence of MTSS1 on ESCC cells. Results Down-regulation of MTSS1 expression was observed both in oesophageal tumour tissues and ESCC cancer cell lines. We also reported that MTSS1 expression was associated with tumour grade p lymph node metastasis p and overall survival p . Patients with high levels of MTSS1 transcripts had a favorable prognosis in comparison with those who had reduced or absent expression levels. Using over-expression and knockdown approach we created sublines from ESCC cells and further demonstrated that MTSS1 expression in ESCC cells significantly influenced the aggressiveness of the oesophageal cancer cells by reducing their cellular migration and in vitro invasiveness. Conclusion MTSS1 serves as a potential prognostic indicator in human ESCC and may be an important target for cancer therapy.
