GSVA and analysis of immune cell infiltration, HAL genes and checkpoint genes expression in 3 immune subgroups. a, b The heatmap was used to visualize these biological processes, and yellow represented activated pathways and blue represented inhibited pathways. The colon cancer cohorts were used as sample annotations. A: Immunity-L vs Immunity-M, B: Immunity-M vs Immunity-H. c The tumor purity of samples from 3 immune subgroups (*P < 0.05, **P < 0.01, ***P < 0.001). d The fractions of 11 types of infiltrating immune cells in samples from 3 immune subgroups. e The RNA expression levels of HLA genes in samples from 3 immune subgroups. f, i The RNA expression levels of checkpoint-related genes (CTLA4, IDO1, LAG3 and PDCD1) in samples from 3 immune subgroups
