Pyroptosis-related genes play a significant role in the prognosis of gastric cancer

Figure 2 Interaction among 199 pyroptosis-related genes. A: Heatmap (blue: low expression level; red: high expression level) of the pyroptosis-related genes between the adjacent nontumor tissues (brilliant blue) and the tumor tissues (red). P values were showed as: ^aP < 0.05, ^bP < 0.01, and ^cP < 0.001; B: Protein–protein interaction network reflecting the interactions of the differentially expressed genes (DEGs); C: The correlation network of DEGs. The correlation coefficients are represented by different colors. Red line: Positive correlation; Blue line: Negative correlation. The depth of the colors indicates the strength of the relevance.
