Using the Database for Annotation, Visualization and Integrated Discovery (DAVID, see URLs), gene lists were mapped onto curated biological processes gene categories using Gene Ontology (GO, The Gene Ontology Consortium). Gene lists were also mapped to pathways and biological processes using the PANTHER classification system (see URLs) and Ingenuity Pathway Analysis (IPA, version 9.0, Ingenuity Systems, see URLs). The most significantly enriched categories of molecules and pathways (smallest p-values, p<0.05) were identified using these tools.
