Gene Ontology analysis reveals biological programs activated during vertebrate tissue regeneration.

DAVID bioinformatics software was utilized to perform gene ontology (GO) term enrichment analysis for those annotated genes that exhibited ≥5-fold upregulation in at least one tissue type for at least one time point during the early regenerative response. Shown are the top 15 most significantly enriched, non-redundant GO_FAT terms associated with those genes. Terms are sorted by the EASE score, which represents a modified, more stringent Fisher Exact P-value. EASE scores ≤0.01 were considered significant.
