MYCN and neuroblastoma: We tested the anticancer effects of disulfiram in four neuroblastoma cell lines with MYCN amplification (IMR-32, SK-N-DZ, SJ-N-TQ-24 and IGR-N91, hereafter named N91) and two without (SK-N-AS and SK-N-SH; note that these lines do express high levels of the oncogene MYC, according to depmap.org).
