Here, using RNA-Seq and chromatin immunoprecipitation-quantitative real-time PCR (ChIP-qRT-PCR) analyses of GBM cell lines, patient-derived glioma stem cells (GSCs) and clinical GBM specimens, we identify a novel signaling pathway whereby EGFR-upregulated H3K23ac binds with TRIM24, and TRIM24 functions as a co-activator to recruit STAT3, leading to stabilized STAT3-chromatin interactions and subsequent activation of STAT3 downstream signaling, thereby enhancing EGFR-driven tumorigenesis. Here, STAT3 is linked to glioma.
