The involvement of the circFOXM1-miR-432-Gα12 axis in glioma cell proliferation and aggressiveness.

ABSTRACT: Accumulating evidence indicates that circFOXM1 (Hsa_circ_0025033) is highly expressed in several cancers; however, the function of circFOXM1 in glioma and the molecular mechanism have not been well explored. In the present study, we found that expression of circFOXM1 was upregulated in both glioma tissues and cell lines. In addition, circFOXM1 knockdown suppressed glioma-cell proliferation, activated apoptosis in vitro, and repressed tumour growth in vivo. Moreover, we clarified that circFOXM1 binds with miR-432, which was downregulated in glioma cells. Furthermore, we indicated that Gα12, a direct target of miR-432, was highly expressed in glioma cells, and Gα12 silencing might limit the progression of glioma. Rescue assays indicated that Gα12 reversed the inhibitory effect of circFOXM1 s
