Abstract

MicroRNAs (miRNAs) perform important roles in the development and progression of human malignancy. miR‑874, as a tumor suppressor, is decreased in malignant tumors, including osteosarcoma. However, the potential mechanism of miR‑874 in osteosarcoma remains largely unknown. In the present study, a dual‑luciferase reporter system supported cyclin‑dependent kinase 9 (CDK9) as a direct target gene of miR‑874. miR‑874 mimics evidently repressed CDK9 expression in osteosarcoma. Furthermore, osteosarcoma tissues and cell lines exhibited increased expression of CDK9, and CDK9 expression levels were inversely correlated (R=‑0.725) with that of miR‑874 in osteosarcoma tissues. Finally, CDK9 overexpression reversed the potential effect of miR‑874 on the proliferation and invasion of osteosarcoma cells. Overall, the results revealed that miR‑874, as a tumor suppressor, is involved in osteosarcoma progression and metastasis by targeting CDK9, indicating that the miR-874/CDK9 pathway may serve as a potential therapeutic target for the treatment of osteosarcoma.
