Abstract
Emerging studies have revealed the critical role of long non-coding RNAs (lncRNAs) in epithelial ovarian cancer (EOC) development and progression. Till now, the roles and potential mechanisms regarding FEZF1 antisense RNA 1 (FEZF1-AS1) within ovarian cancer (OC) remain unclear. The objective of this study was to uncover the biological function and the underlying mechanism of LncRNA FEZF1-AS1 in OC progression. FEZF1-AS1 expression levels were studied in cell lines and tissues of human ovarian cancer. In vitro studies were performed to evaluate the impact of FEZF1-AS1 knock-down on the proliferation, invasion, migration and apoptosis of OC cells. Interactions of FEZF1-AS1 and its target genes were identified by luciferase reporter assays. Our data showed overexpression of FEZF1-AS1 in OC cell lines and tissues. Cell migration, proliferation, invasion, wound healing and colony formation were suppressed by silencing of FEZF1-AS1. In contrast, cell apoptosis was promoted by FEZF1-AS1 knock-down in vitro. Furthermore, online bioinformatics analysis and tools suggested that FEZF1-AS1 directly bound to miR-130a-5p and suppressed its expression. Moreover, the inhibitory effects of miR-130a-5p on the OC cell growth were reversed by FEZF...Continue Reading
