Epithelial-mesenchymal transition (EMT) is one of the decisive steps regulating
cancer invasion and metastasis. However, the molecular mechanisms underlying this
transition require further clarification. MDA-9/syntenin (SDCBP) expression is
elevated in breast cancer patient samples as well as cultured breast cancer
cells. Silencing expression of MDA-9 in mesenchymal metastatic breast cancer
cells triggered a change in cell morphology in both 2D- and 3D-cultures to a more
epithelial-like phenotype, along with changes in EMT markers, cytoskeletal
rearrangement and decreased invasion. Conversely, over expressing MDA-9 in
epithelial non-metastatic breast cancer cells instigated a change in morphology
to a more mesenchymal phenotype with corresponding changes in EMT markers,
cytoskeletal rearrangement and an increase in invasion. We also found that MDA-9
upregulated active levels of known modulators of EMT, the small GTPases RhoA and
Cdc42, via TGF?1. Reintroducing TGF?1 in MDA-9 silenced cells restored active
RhoA and cdc42 levels, modulated cytoskeletal rearrangement and increased
invasion. We further determined that MDA-9 interacts with TGF?1 via its PDZ1
domain. Finally, in vivo studies demonstrated that silencing the expression of
MDA-9 resulted in decreased lung metastasis and TGF?1 re-expression partially
restored lung metastases. Our findings provide evidence for the relevance of
MDA-9 in mediating EMT in breast cancer and support the potential of MDA-9 as a
therapeutic target against metastatic disease.
