CCR5 and glioblastoma: Of the 44 genes identified, 23 genes (e.g., IL6, IL8, TIMP1, CCR5, SREPINE1, and SREPING1) have been reported to be involved in GBM pathogenesis or significant in predicting overall survival, indicating that our big data-based analysis using TCGA and CGGA cohorts has prognostic values.
