since n-myc amplification in neuroblastoma tumors is associated with rapid tumor progression ( 33 ) and n-myc decreases class i mhc antigen expression in rat neuroblastoma cells ( 21 ) , we quantitated levels of n-myc mrna and class i mhc cell surface antigens in a panel of 24 human neuroblastoma cell lines .
