Human neuroblastoma cells were transfected with a pSG5.HA vector containing the DNA-binding and transactivation sequence of RORA (pSG5.HA-RORA), and qRT-PCR analyses were performed to determine the amount of RORA and aromatase transcripts in the transfected cells 24 hrs after transfection. This evidence concerns the gene CYP19A1 and neuroblastoma.
