- EOC demonstrates high expression of GMFG compared to normal, benign and borderline adenomas.
- Up-regulated GMFG expression is associated with a poor prognosis and is an independent prognostic factor for EOC.
- GMFG promotes ovarian cancer cell migration and invasion probably by remodeling actin cytoskeleton.
ObjectiveThe aim of this study was to characterize the clinical significance of GMFG, a novel ADF/cofilin superfamily protein, and investigate its role in cell migration and invasion in epithelial ovarian cancer (EOC).MethodsThe expression of GMFG in EOC tissues and ovarian cancer cell lines was evaluated by immunohistochemistry and immunoblotting respectively. The data were statistically analyzed for the associations of GMFG expression with clinicopathologic parameters and survival. In vitro cell migration and invasion assays were performed to determine the role of GMFG in cell migratory behaviors. The effect of GMFG on reorganization of actin cytoskeleton was investigated by immunostaining.ResultsGMFG was overexpressed in EOC. Up-regulated GMFG expression was closely correlated with advanced FIGO stage and chemoresistance of the disease. EOC patients with higher GMFG expression showed poorer progression-free survival (PFS) and overall survival (OS). In vitro cellular assays revealed that GMFG promoted cell migration and invasion. GMFG expression altered actin cytoskeleton organization probably by interacting with the Arp2/3 complex.ConclusionGMFG expression independently predicts poorer prognosis in patients with EOC. Ectopic overexpression of GMFG contributes to the malignant biological behavior of ovarian cancer cells.
