Further analysis of several GBM public databases, including TCGA RNA-seq database, The Repository of Molecular Brain Neoplasia Data (REMBRANDT) database, and Chinese Glioma Genome Atlas (CGGA), found that the expression of ZNF117 is negatively correlated with patient survival (Supplementary Fig. 9b–d). The gene discussed is ZNF117; the disease is central nervous system cancer.
