We prioritized HDAC2 because of its strong association with the p53 signaling pathway and cell cycle in analysis of TCGA GBM/LGG (IDH‐WT) and CGGA GBM (IDH‐WT) datasets (Figure S5D–G, Supporting Information), relative to HCFC1 (Figure S5H–K, Supporting Information). This evidence concerns the gene TP53 and glioblastoma.
