Finally, DNMT1 expression analysis in TCGA high-grade gliomas classified as mesenchymal and proneural showed a higher expression in proneural samples (mesenchymal 7.5±0.3; proneural 8.1±0.4, p=5.94E-11), consistent with previous findings indicating that G-CIMP glioma mostly belong to the proneural subtype (Figure 2E). The gene discussed is DNMT1; the disease is glioma.
