Western blot analysis was performed to quantify basal levels of both c-MYC and PA2G4 proteins in a panel of cancer cell lines (Figure 2A), including neuroblastoma (SH-SY5Y, SK-N-AS), medulloblastoma (DAOY, UW-228), and Burkitt Lymphoma and B-Acute Lymphoblastic Leukemia (ALL) cell lines (Raji, KOPN-8, SEMK2, P493-6, WEHI-116, WEHI-47). This evidence concerns the gene MYC and acute lymphoblastic leukemia.
