By analysing public datasets through the R2: genomic Analysis and Visualization platform (http://r2.amc.nl), we confirmed in an independent sample cohort of 6 adult non diseased brains, 26 GBMs and 21 oligodendrogliomas [25] that PATZ1 is significantly more expressed in gliomas (including GBMs and oligodendrogliomas) compared to non diseased brain samples (Figure 3A). The gene discussed is PATZ1; the disease is oligodendroglioma.
