  1. aParalogous gene pairs linked with different taxons are mapped to the human cancer signalling map (HCSM). The entire network, as well as the subnetworks consisting of only positive, negative or scaffolding edges, is considered. The overlap between pair sets of different ages and HCSM subnetworks is given in parentheses in the first column. In the second column, the number of shared edges versus the total is given (as the ratio and the resulting percentage value, calculated for the total set of paralogs). In the third column, the average difference in degree between such node pairs is given.
