Synergy network. The network can be seen as a first effort to depict the "prostate cancer interactome" based on the analyzed expression dataset that included 50 healthy and 52 cancerous samples. Each edge depicts inferred gene-gene interactions associated with prostate cancer. Each node of the graph represents a gene. Gene pairs whose synergy has P < 0.05 under permutation B (see text) are indicated by the edges of the graph.
