Correlation analysis revealed that CEBPD is positively correlated with the expression level of CEBPD target genes that are involved in the EGFR/PI3K/AKT pathway (Fig. 7A), even in each GBM subtype (Proneural, Neural, Classical, and Mesenchymal; Fig. 7A, right panel). The gene discussed is CEBPD; the disease is glioblastoma.
