DEG screening and network toxicological analysis. a Volcano plot of DEGs between MDD patients and control. The hub targets were marked with black arrows. b Heatmap of DEGs between MDD patients and control. c The Venn map of Gly-related targets and MDD-related targets. d The PPI network. The width of each edge is proportional to the combined score, whereas the color (from light to dark) and size of each node are proportional to interaction strength
