RASA1 and neuroblastoma: Fig 4B shows that the RasGAP-derived peptide displays a slight sensitization effect toward this cell line. Unlike the NB1 derived-cell lines, TAT-RasGAP317-326 alone was not able to kill LAN-1 cells (Fig 4B), meaning that TAT-RasGAP317-326-induced cell death is not a specificity shared by all neuroblastomas.
