Background: LncRNA DLX6-AS1 has been uncovered to exert effects on various cancers. Nevertheless, the impacts of DLX6-AS1 on endometrial cancer (EC) development remained obscure. The study explored the influence of DLX6-AS1 on EC progression via the microRNA (miR)-374a-3p/zinc-finger protein (ZFX) axis.Methods: EC cell lines were collected and DLX6-AS1, miR-374a-3p, and ZFX levels in EC cell lines were detected. The EC cells were transfected with DLX6-AS1, miR-374a-3p, and ZFX constructs to examine the biological functions of EC cells. The xenograft model was established for detecting tumor growth. Rescue experiments were conducted to verify the interaction of DLX6-AS1, miR-374a-3p, and ZFX in EC cells.Results: DLX6-AS1 and ZFX levels were elevated, while miR-374a-3p exhibited a reduced level in EC cells. Silencing DLX6-AS1 and elevated miR-374a-3p expressions repressed the biological activities of EC cells. Reduced DLX6-AS1 repressed tumor development. MiR-374a-3p silencing reversed the impacts of DLX6-AS1 silencing, while ZFX overexpression abrogated the impacts of miR-374a-3p elevation on EC cell growth. Mechanically, DLX6-AS1 was found to bind to miR-374a-3p, and miR-374a-3p targeted ZFX.Conclusion: DLX6-AS1 depletion restricts the malignant phenotype of EC cells. The study might provide novel therapeutic biomarkers for EC treatment.
