Additionally, other findings showed that maternally expressed gene 3 (MEG3), a well-known lncRNA, was significantly downregulated in meningioma tissues and cells, acting as a tumor suppressor and decreasing the expression of A-kinase anchor protein 12 (AKAP12) by targeting miR-29c to suppress cell cycle, migration, invasion, and proliferation in vitro [71]. Here, AKAP12 is linked to meningioma.
