Development and Verification of an Immune-Based Gene Signature for Risk Stratification and Immunotherapeutic Efficacy Assessment in Gastric Cancer

Figure 1

Differentially expressed immune-related genes and their immune functions in gastric cancer in TCGA dataset. (a) Volcano plot for visualizing the expression of immune-related genes in gastric cancer and normal samples. Red dots indicate upregulation, green dots indicate downregulation, and black dots indicate nonsignificance. (b) Hierarchical clustering analysis of differentially expressed immune-related genes in gastric cancer and normal tissues. (c) GO and (d) KEGG enrichment analysis of differentially expressed immune-related genes.
