Functional network associated with the differentially expressed genes. Schematic diagram of a gene network related to differential expression of sleep quality group (good sleep versus poor sleep). Coloring of genes is based on differential expression (fold changes are shown), down-regulation in green and, up-regulation in red. Genes with no coloring are added from Ingenuity knowledge database. Direct and indirect relationships are shown by solid and dashed lines, respectively. The arrow indicates specific directionality of interactions. Gene associations with some of the digestive system development functions are shown.
