DEGs identification in different datasets of GBM. (a) Volcano diagrams of DEGs from the GBM vs. normal tissues in different datasets. |Log2FC| > 2.0, value < 0.05. (b) The common upregulated genes in GSE4290, GSE7696, GSE13276, and GSE29796 and GEPIA datasets were determined by using Venn diagram. (c) The common downregulated genes in GSE4290, GSE7696, GSE13276, and GSE29796 and GEPIA datasets were determined by using Venn diagram.
