Although these dormancy-associated molecules were found in individual and different amounts, GBM cultures were characterized by a clear mRNA (quantitative PCR) and protein (Western Blot, immunocytochemistry) expression of EphA5, IGFBP5 and H2BK (Figure 3A, black highlighted primary cultures numbers correspond to solid GBM samples depicted in Figure 1A; Figure 7A and 7B). The gene discussed is IGFBP5; the disease is glioblastoma.
