Abstract
Glioma is a general neurological tumor and circular RNAs (circRNAs) have been implicated in glioma development. However, the underlying mechanisms and circRNA biological functions responsible for the regulation of glioma progression remain unknown. In this study, we employ next-generation sequencing (NGS) to investigate altered circRNA expression in glioma tissues. Regulatory mechanisms were studied using luciferase reporter analyses, transwell migration, CCK8, and EdU analysis. Tumorigenesis and metastasis assays were utilized to determine the function of hsa_circ_0010889 in glioma. Our results showed that hsa_circ_0010889 expression increased in glioma cell lines and tissues, indicating that hsa_circ_0010889 may be involved in glioma progression. Downregulation of hsa_circ_0010889 inhibited glioma invasion and proliferation in both in vitro and in vivo experiments and luciferase report assays found that miR-590-5p and SATB1 were downstream targets for hsa_circ_0010889. SATB1 overexpression or miR-590-5p inhibition reversed glioma cells proliferation and migration post-silencing of hsa_circ_0010889. Taken together, our study demonstrates that hsa_circ_0010889 downregulation inhibits glioma progression through the miR-590-5p/SATB1 axis.
