Fig. 2From: Venn-diaNet : venn diagram based network propagation analysis framework for comparing multiple biological experimentsKey concept of Venn-diaNet. a Instantiate a PPI network with the DEGs from the multiple experiments. b When we are interested in C1 that has similar function as C2, we can define C2 as seeds. c Performing network propagation with Markov Random Walk. d Discard C3 genes (as well as seed genes) in order to focus on C1 genes. Remaining genes are ranked by the probability score calculated from the previous stepBack to article page
