In solid human astrocytomas (A) WHO grade II and III as well as in GBM samples EphA5, IGFBP5 and H2BK were expressed (with single exceptions) on well detectable levels without any widespread differences between individual tumor entities [Figure 1A; average ΔCT values for GBM samples: 8.47 (EphA5), 3.40 (IGFBP5), 6.29 (H2BK)]. Here, H2BC12 is linked to glioblastoma.
