NRG1 and medulloblastoma: Next, we moved our attention to genes already related to medulloblastoma based on the literature and validated some of them, such as POSTN [52], BOC [53], VCAM1 [54], and TP63 [55] among the downregulated genes and ANKRD1 [56], THBS1 [57], NRG1 [47], PTHLH [58], and HBEGF among the upregulated ones in DAOY and D283Med cells (Figure 6E,F and Figure S6A).
