RAB3D and central nervous system cancer: Additionally, hsa_circ_0088732 further accelerated the glioma cell migration and invasion mediated by miR-661 mimics and RAB3D, suggesting that the combined effects of hsa_circ_0088732 and RAB3D could rescue the migration and invasion mediated by miR-661 mimics (P < 0.05, P < 0.01, Figures 9C–E).
