LncRNA KCNQ1OT1 acting as a ceRNA for miR-4458 enhances osteosarcoma progression by regulating CCND2 expression
Osteosarcoma is prevalent worldwide and characterized as a challenging health burden. It has been increasingly indicated that long non-coding RNAs (lncRNAs) are significant in pathological processes of numerous cancers, exerting oncogenic or tumor-suppressive function. However, the participation of KCNQ1OT1 in osteosarcoma has not been elaborated. In this study, we focus on interrogating the function of KCNQ1OT1 and its underlying mechanism in osteosarcoma. Our work demonstrated the upregulation of KCNQ1OT1 in osteosarcoma through qRT-PCR. Besides, loss of function assay (CCK-8, transwell migration) indicated KCNQ1OT1 promoted cell proliferation, migration in osteosarcoma. Mechanically, KCNQ1OT1 acting as sponge for miR-4458 antagonized its tumor-suppressive impact on CCND2 expression. The anti-apoptotic nature of KCNQ1OT1 was also unveiled via caspase-3 activity assay. Overexpressed KCNQ1OT1 acted as competing endogenous RNA (ceRNA) for miR-4458 and subsequently reinforced target gene CCND2. Collectively, the results of rescue experiments suggested that the oncogenic role of KCNQ1OT1 was performed through sponging miR-4458 and upregulating CCND2 during osteosarcoma development, providing a novel perspective of intervention in osteosarcoma management.
