The KEGG ontology (KO) numbers were retrieved using the KAAS annotation server. Using the KO numbers, pathway maps were constructed using the KEGG pathway reconstruction tool. The pathways with the largest percentage of up-regulated KO functions are shown. Human disease-related pathways and overview maps are not shown.
