The proliferative and invasive nature of malignant cancers drives lethality. In glioblastoma, these two processes are presumed mutually exclusive and hence termed ?go or grow?. Here, we identified a molecular target that shuttles between these disparate cellular processes?the molecular motor KIF11. Inhibition of KIF11 with a highly specific small molecule inhibitor stopped the growth of both the more treatment resistant glioblastoma tumor initiating cells (TICs, or cancer stem cells) as well as non-TICs and impeded tumor initiation and self-renewal of the TIC population. Targeting KIF11 also hit the other arm of the ?go or grow? cell fate decision by reducing glioma cell invasion. Administration of a KIF11 inhibitor to mice bearing orthotopic glioblastoma prolonged their survival. In its role as a shared molecular regulator of cell growth and motility across intratumoral heterogeneity, KIF11 is a compelling target for glioblastoma.
