EP300 expression predicts survival for patients with glioblastoma. The role of EP300 in glioblastoma was validated by examining gene expression profiling data from two independent datasets of glioblastoma, TCGA (A) and Erasmus (B). Kaplan-Meier curves for 260 patients (A) and 153 patients (B) are shown. Samples were separated into high (green) and low (red) expression groups by recursive partitioning analysis. Median survival times for each group are shown in parentheses.
