TP53 and neuroblastoma: Using NGP cells lentivirally transfected with a short hairpin RNA against human TP53 (NGP-LV-hp53) or murine TP53 (NGP-LV-mp53), we were able to confirm and validate the upregulation four miRNAs (miR-222-3p, miR-432-5p, miR-203a, and miR-182-5p) by p53 in neuroblastoma cells.
