Schematic representations of PPI networks related to HF. A. Core HF PPI network. B. Degree distribution of the core network. In A, nodes and edges represent proteins and interactions respectively. Nodes located near the center represent highly-connected nodes, or nodes at the intersection between different node-node pathways. In B, the relationship between node degree and the observed frequency is plotted on a logarithmic scale (ln) for this network.
