a

Gene Ontology (GO) Biological process category annotations for the differentially expressed genes in each analysis.

b

Probe IDs, the number of Affymetrix Probe IDs that were differentially expressed in each analysis; Unique genes, the number of unique genes corresponding to the Probe IDs; Annotated Genes, the number of unique genes that have annotations associated with them in the GO database; GO IDs, the number of appearances of GO IDs associated with the annotated genes; Unique GO IDs, the number of unique GO IDs associated with the annotated genes. Numbers in paratheses indicate the percentage of unique genes that have associated GO annotations.
