The transcription factor sex determining region (Y SRY)-box 2 (SOX2) is known to
play a crucial role in the maintenance of self renewal or pluripotency of
undifferentiated embryonic and neuronal stem cells. An elevated expression of
SOX2 has been correlated with poor prognosis of esophageal squamous cell
carcinoma (ESCC). We sought to investigate the mechanism(s) by which SOX2
modulates the ESCC metastasis. The SOX2 coding DNA sequence was inserted into
pCMV vector and stably transfected in ESCC cells (Eca-109). The effect of SOX2
over expression was evaluated on cell migration, invasion and epithelial to
mesenchymal transition (EMT). We also measured the expression of Slug to explore
if this transcription factor is involved in SOX2-mediated regulation of cell
migration/invasion and EMT. In addition, we determined the role of STAT3/HIF-1?
to further probe the mechanism of SOX2-mediated metastasis via Slug. Our results
demonstrated that SOX2 over expressing Eca-109 cells showed an enhanced cell
migration/invasion. Moreover, these cells exhibited the EMT characteristics, that
is, a significantly suppressed expression of the epithelial cells marker with a
concomitant enhancement of those of the mesenchymal markers. An increased
expression of Slug in SOX2 over expressing cells suggested the involvement of
this transcription factor in SOX2-regulated metastasis. Whereas the expressions
of STAT3/HIF-1? were found to be up-regulated in SOX2 expressing cells, blockade
of these transcription factors resulted in the inhibition of Slug expression at
both protein and mRNA levels. CONCLUSION: These results suggest that SOX2
promoted the metastasis of ESCC, at least in part, by modulating Slug expression
through the activation of STAT3/HIF-1? signaling.
