KEGG pathways (Figure 5(d)) enriched by the DELs-correlated co-expressed coding genes included protein digestion and absorption, bile secretion, extracellular matrix (ECM)-receptor interaction, insulin secretion, ribosome, systemic lupus erythematosus, GABAergic synapse, retrograde endocannabinoid signaling, alcoholism, viral carcinogenesis, pancreatic secretion, and focal adhesion. This evidence concerns the gene INS and alcohol drinking.
