Figure 6. MS4A6A expression was positively correlated with ICP-related genes. (A) Correlation of MS4A6A expression with ICP-related genes. (B) Comparison of MS4A6A expression with common immune checkpoint expression in TCGA-LUAD cohort. (C) Correlation of MS4A6A expression profile with ICP-related genes in the pan-cancer cohort. **P < 0.01, ***P < 0.001.
