SYF2 is upregulated in human epithelial ovarian cancer and promotes cell proliferation

Abstract

SYF2 is reported to be as a cell cycle regulator at the G1/S transition and encodes a nuclear protein that interacts with cyclin-D-type binding protein 1. In our study, we investigated the role of SYF2 in human epithelial ovarian cancer (EOC) progression. Western blot and immunohistochemistry analysis displayed that SYF2 was overexpressed in EOC tissues and EOC cell lines. In addition, the immunoreactivity of SYF2 was positively correlated with tumor grade and Ki-67 expression. In vitro, serum starvation-refeeding experiment and SYF2-siRNA transfection assay demonstrated that the expression of SYF2 was promoted in the proliferative progression of EOC cells, while knockdown of SYF2 expression decreased and inhibited cell growth rate of EOC cells. With all the results, we support that SYF2 might contribute to EOC progression via modulation of proliferation in EOC cells and would provide a novel therapeutic target of human EOC.
