p53-mutant MB cell line was used to investigate the signaling pathway that regulates proliferation, migration, and drug resistance using inhibitors of HDAC (LBH-589) and PI3K/mTOR [Buparlisib (BKM-120)/rapamycin)]or CUDC-907 (dual inhibitor of HDACs and PI3K/AKT). Results demonstrated that...MB cells displayed strong resistance to BKM-120, whereas LBH-589 or CUDC-907 caused apoptosis...
