Article Title: 3-O-acetyl-11-keto-β-boswellic acid exerts anti-tumor effects in glioblastoma by arresting cell cycle at G2/M phase

doi: 10.1186/s13046-018-0805-4

Figure Lengend Snippet: 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
