Boxplots of the most differentially expressed ligand or receptor genes across 10 cancer-normal tissue comparisons. (a) The boxplots of top 10 down-regulated ligand/receptor genes in cancer tissues compared with normal tissues. Each small panel is the gene expression boxplot comparison between normal (left) and cancer (right) tissues in one cancer type (brca – breast cancer etc.). Different color represents different genes. (b) The boxplots of top 6 up-regulated ligand/receptor genes in cancer tissues compared with normal tissues.
