Abstract
Aim: To discuss F11-AS1’s effects and mechanisms in ovarian cancer development. Methods: Evaluating F11-AS1 expression by ISH assay and F11-AS1 mRNA level in difference cell lines by RT-qPCR assay. Using MTT, flow cytometry, transwell and wound healing assay to evaluate SKOV3 cell proliferation, cell apoptosis, invasion and migration. And using WB assay to measure PTEN, p-PI3K, AKT, P53 and MMP-9 proteins expressions. Results: F11-AS1 was significantly down-regulation with stage increasing in cancer tissues (P <0.01, respectively). With F11-AS1 transfection, the SKOV3 cell proliferation rate was significantly depressed with cell apoptosis and G1 phase rate significantly increasing (P <0.001, respectively). And then, invasion cell number and wound healing rate of lncRNA group which transfected with F11-AS1 significantly down-regulation (P <0.001). By WB assay, PTEN and P53 proteins expressions significantly up-regulation and p-PI3K, AKT and MMP-9 proteins expressions were significantly down-regulation (P <0.001). Conclusion: F11-AS1 depresses ovarian cancer biological activity by regulating PTEN by vitro study.
