Abstract: Objective To investigate the expression of LncRNAs ABHD11-AS1 in ovarian cancer cell and oviductal epithelial cell and explore the effect of LncRNAs ABHD11-AS1 on ovarian cancer cell proliferation. Methods The level of LncRNAs ABHD11-AS1 and miR-133a was detected by Real-time PCR, and interaction between them was confirmed by Dual- Luciferase reporter assay (DR). Cells were transfected with NC siRNA, ABHD11-AS1 as well as siRNA NC mimic, miR-133a mimic and NC inhibitor and miR-133a inhibitor, respectively, and the proliferation was detected by Cell Counting Kit-8 (CCK-8) assay. Real-time PCR and western blotting were performed to detect the EGFR expression. Results Downregulation of lncRNAs ABHD11-AS1 could significantly inhibit the proliferation of ovarian cancer cells. Moreover, lncRNAs ABHD11-AS1 was negatively correlated with the expression of miR-133a. DR results showed that luciferase activity was significantly reduced in cells transfected with miR-133a mimic and wild-type ABHD11-AS1 fragments; and the level of miR-133a was lower in ovarian cancer cell compared to oviductal epithelial cells. Transfection of miR-133a mimic significantly upregulated miR-133a expression in both of these cells and inhibited their proliferation and EGFR expression. In addition, downregulating miR-133a significantly promoted the proliferation of ovarian cancer cells and increased the EGFR expression, while downregulating LncRNAs ABHD11-AS1 significantly decreased the EGFR expression. Conclusion LncRNAs ABHD11-AS1 promoted the malignant behaviors of ovarian cancer by targeting miR-133a to upregulate its downstream target gene EGFR.
