Glioblastomas have limited treatment options and dire prognoses. A study now shows that GAP43-mediated transfer of functional mitochondria from astrocytes to glioblastoma cells leads to metabolism, signaling and epigenome remodeling that favor tumor growth, thus highlighting GAP43 inhibition as a promising therapeutic strategy for glioblastoma.
