EGFR and glioblastoma: Gene ontology (GO) analysis showed enrichment of “DNA replication-dependent nucleosome assembly”, “chromatin silencing at rDNA”, “regulation of gene silencing by miRNA”, “DNA packaging”, “posttranscriptional gene silencing”, “gene silencing by RNA”, “negative regulation of gene expression, epigenetic”, “regulation of gene silencing”, “protein-DNA complex subunit organization”, and “DNA replication-independent nucleosome organization” pathways being hypomethylated in EGFR amplified glioblastomas.
