Figure 1. DEGs screened in GBM and adjacent tissues. (A) The distribution of genes in normal tissues and glioblastoma tissues screened by RNA sequencing using clustering analysis. (B) The distribution of genes whose change in expression of false discovery rate (FDR) < 0.01 was marked in red on the MA plot (log total counts versus log2 fold-change). The distribution of genes with a change in expression of log2 fold-change (FC) ≥ 4 was represented in red on the volcano plot (log2 fold-change versus log FDR).
