    Abstract:
    OBJECTIVE: To dissect the functioning mode of miR-582-5p on gastric cancer cell growth and provide therapeutic targets for gastric cancer. PATIENTS AND METHODS: Relative expression levels of miR-582-5p in human gastric cancer tissue samples and gastric cancer-derived cell lines were measured by using quantitative Real-time PCR. Cell proliferation and viability capacities were assessed by cell counting kit-8 (CCK8) assay and colony formation assay. Cell apoptosis and cell cycle distribution were identified by flow cytometry. Downstream target gene was confirmed by using luciferase and Western blotting assays. RESULTS: MiR-582-5p was downregulated in gastric cancer tissues when compared with para-carcinoma tissues (n=42). Overexpressed miR-582-5p could attenuate cell proliferation and viability capacities, as well as promoted cell apoptosis and cell cycle arrest at G0/G1 phase. AKT3 was chosen as the target gene of miR-582-5p by bioinformatics analysis and luciferase reporter assay. Moreover, restoration of AKT3 could impair tumor suppression role of miR-582-5p on gastric cancer growth. CONCLUSIONS: MiR-582-5p exerted tumor-suppressive effects on gastric cancer growth via targeting AKT3 in vitro, which provided an innovative and candidate target for diagnosis and treatment of gastric cancer.
