Endometrial cancer is a common gynecological malignancy, and the incidence of this disease has increased in recent years. Recently, some studies suggested that the expression of miR-379-5p suppressed the metastasis of breast cancer cells. However, whether the expression of miR-379-5p could affect the proliferation, migration and invasion of endometrial cancer is unclear. In this study, we established miR-379-5p overexpression and miR-379-5p inhibition in endometrial cancer cells. Next, EdU and colony formation assays were performed to measure proliferation of endometrial cancer cells. Wound healing and transwell assays were carried out to examine the migration and invasion of these cells. Then, luciferase reporter assay was performed to test the relationship between miR-379-5p and ROR1. Finally, we overexpressed ROR1 in miR-379-5p overexpressing endometrial cancer cells. Colony formation, wound healing and transwell assays were used to measure proliferation, migration and invasion of these cells. The results showed that overexpression of miR-379-5p repressed proliferation, migration and invasion of endometrial cancer cells. Higher levels of miR-379-5p repressed expression of N-cadherin, Vimentin and ZEB1. Overexpression of miR-379-5p also promoted expression of E-cadherin and ZO-1. In addition, miR-379-5p targeted and suppressed expression of ROR1. Overexpression of ROR1 abolished the inhibitory effect of miR-379-5p on proliferation, migration, invasion and EMT of endometrial cancer cells. All of these results indicated that miR-379-5p suppressed proliferation, migration and invasion of endometrial cancer cells by inhibiting the expression of ROR1 and the EMT process.
