The co-expression network between DEGs and DELs in HCC. a The co-expression network of metabolic pathway containing 626 connections between 119 DELs and 55 DEGs with absolute r value larger than 0.8. The orange boxes represent DEGs, and the blue hexagons represent the DELs. The edges between DEGs and DELs indicate the potential correlation, of which the color and the thickness standing for different correlation coefficient were marked within the frame. b The co-expression network of cell cycle pathway containing 52 connections between 28 DELs and 12 DEGs. c The co-expression network of chemical carcinogenesis pathway containing 113 connections between 59 DELs and 11 DEGs. d The co-expression network of complementary and coagulation cascades pathway containing 179 connections between 58 DELs and 10 DEGs
