  1. 39 well-characterized genes were significantly upregulated (FC > 2 and p < 0.001) in oligodendrogliomas with 1p19q codeletion in comparison to each of the 4 other sample groups. Underlined genes were studied and validated by real-time RT-PCR in the independent sample set. FD/EGFR = Fold difference of geometric means (FD) in gliomas with 1p19q codeletion in comparison to gliomas with EGFR amplification, FD/Cx = FD in gliomas with 1p19q codeletion in comparison to cortex samples, FD/CC = FD in gliomas with 1p19q codeletion in comparison to corpus callosum, FD/Stem cells = FD in gliomas with 1p19q codeletion in comparison to glioblastomas cancer stem cells [7].
