Sumario:OBJECTIVE: Circular RNA is a newly discovered non-coding RNA. It plays an important role in regulating gene expression, and may take part in tumor progression. This study aimed to investigate the functions of hsa_circ_0008792 in osteosarcoma regulation. METHODS: We identified a circular RNA, hsa_circ_0008792, by using bioinformatics to analyze the GSE96962 dataset. The capacities of migration and invasion were assessed by wound-healing assay and transwell Matrigel assay. The ratios of G0/G1, S, and G2/M phases in cell cycle and apoptosis were measured using flow cytometry. RESULTS: Hsa_circ_0008792 is expressed at low levels in osteosarcoma cells, and up-regulation of hsa_circ_0008792 could suppress osteosarcoma cell migration and invasion and promote apoptosis. This regulation is mediated by hsa-miR-711/ZFP1. The expression level of hsa_circ_0008792 showed no influence on cell cycle of osteosarcoma cells. CONCLUSION: Osteosarcoma is suppressed by hsa_circ_0008792/hsa-miR-711/ZFP1 axis.
