Several genes participate in more than one biological process.

Heat map of top scored signaling pathways enriched in heart failure microarray analysis. Every row represents a gene, and every column represents a pathway. Top significant signaling pathways for commonly enriched genes are presented on the heat map in black. Pathway enrichment analysis was done using Advaita iPathway Guide, and full list of pathways can be found in S1–S3 Tables. Only genes that have fold change above two were presented in the heat map.
