MYCN and neoplasm: Our investigation of Myc family members in Fig. 4 revealed that MYCN amplification is enriched in high-NE-score neuroblastoma cell lines, MYCL amplification is enriched in high-NE-score SCLC cell lines, whereas increased MYC gene expression is observed in low-NE-score cell lines and tumor samples of both SCLC and neuroblastoma.
