On, the available regulatory motifs are bistable switches, oscillation motif and adaptation motif. In Figure 8, the motif designer interface shows one of bistable switch motifs selected in known regulatory motif list. After creating regulatory motif, users should save the regulatory motif in the motif designer interface. 1480666 When users click the save button, it automatically checks isomorphic relationship by comparing saved regulatory motifs with currently selected regulatory motif and saves it into saved regulatory motif list. These saved regulatory motifs are finally transferred into the network analysis pipeline as query regulatory motifs.motif member table. The individual regulatory information includes a list of motif member nodes and structural properties, such as path, sign, length between nodes, and the size of regulatory motif. To facilitate the visual exploration of the occurrence of a regulatory motif within the analyzed network, it allows users to highlight the matches by clicking the individual regulatory motif in motif member table. In Figure 9, the motif explorer interface shows the highlight of bistable switch motif in the network viewer and the motif member table.Example of Regulatory Motif AnalysisThe hallmark of apoptosis is the all-or-none activation of caspase-3 in response to various apoptotic signals [29]; BTZ043 chemical information Therefore, we used the apoptosis regulation network composed of 11 nodes and 15 edges. We used RMOD to examine the regulatory motifs FCCP obtained from the analysis of the apoptosis regulation network. As shown in Figure 9, our analysis result shows that the apoptosis regulation network contains 9 bistable switch motifs. Interestingly, these are all classified into 3 types of bistable switch motifs, including positive feedback loop. Their individual regulatory motifs show different sizes, even though individual regulatory motifs are included in the same compressed forms of regulatory motif class. Remarkably, it shows that caspase-3 is involved in all positive feedback loops in detected bistable switch motifs. Therefore, we investigated several computational modeling studies focusing on the bistable activity of caspase-3 in apoptosis. We found a positive feedback loop including caspase-3, which is necessary to cause bistable response of caspase-3 [28,30]. Our analysis result implies that the bistable behaviour of caspase-3 inAnalyzing a NetworkAfter creating the input network and query regulatory motifs, RMOD provides two options for analyzing input network: (i) analysis of the whole network or (ii) analysis of nodes along a userdefined path. To designate user-defined path, the users can query a network by selecting a source node and a target node and then RMOD finds the shortest paths that connect these 2 elements in network. After analyzing input network, RMOD shows the summarized result of regulatory motif analysis. As shown in Figure 9, it allows users to examine how often detected regulatory motif match the query regulatory motifs. When users select a regulatory motif, it shows the compressed forms of regulatory motifs in the motif structure viewer and provides the individual regulatory motif information from theRMOD: Regulatory Motif Detection ToolFigure 9.
