Since we have shown that Zhangfei has a profound influence when ectopically expressed in ONS-76 human medulloblastoma cells [27,35], we compared RNA purified from ONS-76 cells infected with adenoviruses expressing either Zhangfei (AdZF) or the control protein β-galactosidase (AdLZ, Figure 1A). The gene discussed is CREBZF; the disease is medulloblastoma.
