Therefore, here we investigated how the combined treatment of BGA002 and RA would affect MYCN expression in a broad panel of neuroblastoma cell lines (17 cell lines, which recapitulated the neuroblastoma landscape: MNA cell lines (n = 10), MNA p53-mutated (n = 3), non-MNA (n = 3), and non-MNA p53-mutated (n = 1)). The gene discussed is TP53; the disease is neuroblastoma.
