Of note, re-transplantation of cells from tumor #2 containing mycN and Survivin transgenes and from tumor #19 containing the mycN transgene alone showed dramatically shortened tumor latency when compared to tumors produced by freshly transduced U251-MGmycN/Survivin and U251-MGmycN/C cells (Fig. 7g). The gene discussed is BIRC5; the disease is neoplasm.
