Fig 6. Enrichment map of Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways for the darkgreen consensus co-expression module.

Symbol explanation as in Fig 4. Several pathways dealing with nucleic acid metabolism, such as DNA replication and RNA degradation are significant in this pathway. The expression trend of this module increased linearly until age 10 months after which it stabilized, suggesting increasing activity of these pathways until a stable activity level is reach in old age.
