Figure 1. Differentially expressed immune-related genes (IRGs). (A, B) Heatmap and volcano plot of the upregulated (red) and downregulated (green) genes between the MSI-L/MSS and MSI-H samples of gastric cancer. (C, D) Profiling data of the IRGs are shown in heatmap and volcano plot, red dots represent upregulated and green dots represent downregulated. (MSI-H, microsatellite instability-high status; MSI-L, microsatellite instability-low status; MSS, microsatellite stable).
