TP53 and neuroblastoma: Neuroblastoma xenograft models included NB-1 (ALK-amplified, MYCN amplified), NB-SD (moderate surface ALK-expression, ALK F1174L mutated, MYCN amplified, TP53 mutated), COG-N-424x (moderate surface ALK-expression, ALK WT, MYCN amplified), SK-N-AS (low surface ALK expression, ALK WT, MYCN non-amplified, TP53 mutated), NGP ALK WT (moderate surface ALK-expression, MYCN amplified, TP53 mutated) and NGP ALK KO (ALK null, MYCN amplified, TP53 mutated) (Supplemental Table 7).
