OBJECTIVE: We aimed to explore the expression of circRNA_009934 in osteoclast, as well as its potential roles in regulating osteoclastogenesis and bone resorption via regulating miR-5107.

MATERIALS AND METHODS: We performed qRT-PCR analysis to examine the expression of circRNA_009934 in osteoclast in distinctive stages. We used CCK-8 assay to detect the cell proliferation ability. Correlation analysis between the expression levels of circRNA_009934 and miR-5107 was performed using statistical analysis. Bioinformatics prediction was performed to predict the binding site of circRNA_009934 and miR-5107, subsequently followed by Luciferase assay for validation. The mice TRAF6 3′-UTR were cloned into the Luciferase reporter vector and miR-5107 binding mutants were constructed to validate the inhibited regulation of miR-5107 to the expression of TRAF6.

RESULTS: Our results showed that expression of circRNA_009934 was increased during osteoclast differentiation. CircRNA_009934 expression was closely correlated with osteoclastogenesis and bone resorption activity. Bioinformatics prediction and Luciferase assay demonstrated that circRNA_009934 served as a ceRNA of miR-5107 and regulated its downstream TRAF6 expression.

CONCLUSIONS: We first demonstrated that circRNA_009934 expression was increased in osteoclasts, which promoted osteoclastogenesis by serving as a ceRNA of miR-5107 and regulated the expression of TRAF6.
