We analyze protein–protein interaction networks for six different species under the framework of random matrix theory … quantifies long range correlations in eigenvalues, for all protein–protein interaction networks follow random matrix prediction …

Discovering motifs in protein–protein interaction networks is becoming a current major challenge in computational …

, this paper firstly takes essential genes as reference to analyze the topological properties of human genes with protein–protein … interaction network. Empirical results demonstrate that nonessential disease genes are topologically more important and closer to …

ρ in World Wide Web, while in protein–protein Interaction network, a scaling law can be observed in describing the …

We employ the random graph theory approach to analyze the protein–protein interaction database DIP. Several global … topological parameters are used to characterize the protein–protein interaction networks (PINs) for seven organisms. We find that … fruit fly protein–protein interaction dataset does not have convincing evidence in favor of the hierarchical network model …
