TTN and glioblastoma: In glioblastomas, for example, decreasing the expression of TTN‐AS1 could remarkably prolong the survival of mice and reduce the volume of tumor through promoting apoptosis and inhibiting the migration, proliferation, and invasion of glioblastoma cells, which may be correlate with the reduction of binding between miR‐320b and transcriptional factor EGR3 mRNA.9
