To investigate whether CITK could be a potential target for Group 3 and Group 4 (G3/G4) medulloblastoma (MB), we resorted to the established human medulloblastoma cell lines D283 (p53 wt, no myc amplification) and D341 (p53 wt, myc amplification) [32]. The gene discussed is TP53; the disease is medulloblastoma.
