In addition, gene expression from over 1100 cell lines in the cancer cell line encyclopaedia database showed that levels of DCAF15 in neuroblastoma cell lines was the highest among all solid tumour types (Supplementary Fig. 6b), further supporting the hypothesis that neuroblastoma patients could represent a target population for therapeutic intervention with aryl sulfonamides, such as indisulam. Here, DCAF15 is linked to neuroblastoma.
