Figure 2. Inflammatory Δage-related subnetwork derived from protein-protein interaction.

Each node represents one gene, whereas each edge represents the interaction between two genes. The nodes were colored to represent their association with inflammatory Δage by z-score: red represents genes that were positively associated with inflammatory Δage, whereas green represents genes that were negatively associated with inflammatory Δage. The node size is proportional to the number of edges that the node connects to.
