ABSTRACT
Osteosarcoma (OS) is a malignant disease with high morbidity and mortality rates in children and adolescents. Evidence has indicated that long noncoding RNAs (lncRNAs) may serve important roles in human cancer progression, including OS. In the present study, the role of lncdouble homeobox A pseudogene 8 (DUXAP8) in the development of OS was identified. The expression of lncRNADUXAP8 was determined by reverse transcriptionquantitative polymerase chain reaction in OS tissues. Cell proliferation was evaluated using Cell Counting kit8 and colony formation assays, and Transwell assays were conducted to measure cell invasion. Cell migration was evaluated using a wound healing assay. The binding site between lncDUXAP8 and miR635 RNAs was investigated using a luciferase reporter assay. The expression of lncDUXAP8 was significantly upregulated in OS samples and OS cell lines compared with normal tissues. High expression of lncRNA DUXAP8 was associated with shorter overall survival times. Knockdown of lncRNA DUXAP8 inhibited proliferation, migration and invasion in OS cells. Notably, mechanistic investigation revealed that lncRNA DUXAP8 predominantly acted as a competing endogenous RNA in OS by regulating the miR635/topoisomerase alpha 2 (TOP2A) axis. lncRNA DUXAP8 is upregulated in OS, and lncRNA DUXAP8knockdown serves a vital antitumor role in OS cell progression through the miR635/TOP2A axis. The results of the present study suggested that lncRNA DUXAP8 may be a novel, promising biomarker for the diagnosis and prognosis of OS.
