Disruption of Cooperation Between Ras and MycN in Human Neuroblastoma Cells Promotes Growth Arrest

Abstract excerpt

PURPOSE: Our aim was to examine whether active Ras and MycN cooperation contributes to the malignant phenotype of human neuroblastoma with amplified MycN gene, an aggressive incurable tumor. EXPERIMENTAL DESIGN: Human neuroblastoma LAN-1 cells, in which the MycN gene is amplified, were used to examine the impact of the Ras inhibitor farnesylthiosalicylic acid on cell growth, on the levels Ras and MycN proteins,...
