Fig. 6From: Germline HLA-B evolutionary divergence influences the efficacy of immune checkpoint blockade therapy in gastrointestinal cancerCorrelation between HLA-B HED and the expression of immune-related genes. a Heatmap of differentially expressed genes (DEGs) between the low HLA-B HED and high HLA-B HED subgroups in the PUCH cohort. DEGs were obtained from a 395-plex RNA immune oncology (RNA IO) profiling platform. b Volcano plot of DEGs. c Pathway enrichment analysis of DEGs by using the enrichPathway function from the ReactomePA R packageBack to article page
