High levels of SCIN expression in GC tissue predict a poor outcome in patients.
SCIN enhances the invasive and metastatic capabilities of GC cells in vitro and in vivo.
Filopodium formation is involved in the SCIN- promoted invasion and metastasis of GC cells.
Suppression of SCIN in GC cells is accompanied by decreased expression of Cdc42, an important regulator of filopodia.
