Proposed mechanistic scheme: AKBA suppresses glioblastoma by arresting cell cycle at G2/M phase. AKBA activates p21 which decreases expression of FOXM1 and its downstream target genes including Aurora A, Aurora B, PLK1, and cyclin B1. Inhibiting Aurora A suppresses the expression of PLK1 which leads to the inactivation of CDK1/cyclin B1 complex and arrests the cell cycle at the G2/M checkpoint. Inhibiting Aurora B decreases expression of TOP2A and inhibits mitosis
