Figure 3From: ARACNE: An Algorithm for the Reconstruction of Gene Regulatory Networks in a Mammalian Cellular ContextTopology of the 100 gene regulatory networks proposed by Mendes. Blue/red edges correspond to activation/inhibition. For the Erdös-Rényi topology (a) each gene is equally likely to be connected to every other gene, while the scale-free topology (b) is characterized by large interaction hubs with many connections.Back to article page
