TP53 and medulloblastoma: We analyzed expression by qRT-PCR patient-derived lines Daoy, D283 and D425 for N/C-MYC and GABRA5. Daoy is reported as SHH subgroup derived [24], while D283 is a group 3 medulloblastoma line, TP53-wildtype [25], and D425 is a group 3 medulloblastoma line, TP53-mutated [26].
