Figure 1. Identification of differentially expressed genes (DEGs) in GC. (A, B) DEG heatmaps of GC and normal tissues from the GSE65801 (A) and TCGA (B) datasets. (C, D) DEG volcano plots of GC and normal tissues from the GSE65801 (C) and TCGA (D) datasets. (E, F) Venn diagram showing the up- (E) and downregulated overlapping DEGs (F) between the GSE65801 and TCGA datasets. DEGs, differentially expressed genes; FC, fold change; GC, gastric cancer; and TCGA, The Cancer Genome Atlas.
