Protein-protein interaction map is a key gateway into liver regeneration

Figure 5 A protein-protein interaction map of transcription factors associated with liver cell proliferation. Node stands for protein and the edge means the two proteins are interactive; the node size symbolizes the degree of this protein (the more highly connected with others, the bigger node); the edge target arrow shape and color: delta and blue, interactions are only validated by yeast two-hybrid (Y2H); diamond and green means validated by Y2H and α-glutathione S-transferase pull-down; T and black means validated by Y2H and co-immunoprecipitation.
