Screening and expression analysis of PMTRGs. (A) Volcanic plot of proneural and mesenchymal GBM transcriptome differential genes from the TCGA, CGGA325, and CGGA301 platforms. (B) Venn diagram of differentially upregulated genes in the three platforms. (C) mRNA correlation analysis of 17 PMTRGs. (D) Protein–protein interaction network and functional annotation of PMTRGs. (E) Expression profiles of PMTRGs in four subtypes of GBM.
