DOCK5 and glioblastoma: Our results indicated that PSAP released from eight cell types could potentially target the C0 DOCK5+ GBM subpopulation, the C1 SOX6+ Oligodendrocytes subpopulation, and the C2 CRYAB+ GBM subpopulation, while PSAP released from the other six cell types did not target any specific cells (Figure 5K).
