As a complementary analysis based on genetic methods, we considered a public data set of RNA interference data from the Broad institute DepMap43, in which the tested neuroblastoma cell lines (n = 9) are more vulnerable to MAPK8 knockdown than non-neuroblastoma cell lines (n = 704), but not MAPK9 or MAPK10 (Supplementary Fig. 4G). This evidence concerns the gene MAPK9 and neuroblastoma.
