OBJECTIVE: Long non-coding RNAs (lncRNAs) have been found to exert specific functions in the progression of ovarian cancer (OC), except for lncRNA-OIP5-AS1. In this study, we aim at exploring the molecular mechanisms of OIP5-AS1 in OC.

PATIENTS AND METHODS: The expression levels of OIP5-AS1, miR-324-3p, and NFIB in OC tissues and OC cell lines were explored by qRT-PCR assay. The OC cell vitality was examined by CCK-8 and transwell assay. The protein expression level of NFIB was measured by Western blot analysis. The correlation between OIP5-AS1, miR-324-3p, and NFIB was appraised by Dual-Luciferase reporter assay.

RESULTS: OIP5-AS1 and NFIB were validated to be upregulated in both OC tissues and OC cell lines. Inversely, miR-324-3p downregulation was found in OC tissues and OC cell lines. Functionally, OIP5-AS1 knockdown and miR-324-3p overexpression restrained SKOV3 cell viability, invasion, and migration. Our results verified that OIP5-AS1 inhibited the expression of miR-324-3p in OC. Moreover, miR-324-3p directly targets NFIB. Besides that, NFIB silencing restrained the progression of SKOV3 cells.

CONCLUSIONS: The present study clarified that OIP5-AS1 accelerated OC progression by sponging miR-324-3p and upregulating NFIB. OIP5-AS1 can be a possible therapeutic target for the treatment of OC.
