List of Gene Ontology (GO) biological process terms that were significantly enriched (FDR ≤ 0.01) with differentially expressed genes (DEG) detected simultaneously in both pairwise comparisons involving the wild-type (WT) mammary glands on day 10 of lactation: WT <i>vs</i>. Knock-out (A) and WT <i>vs</i>. Rescue (B).

<p>The graph shows the term name, the total number of genes within each term, and the number of genes up-regulated (green) and down-regulated (yellow) in the knock-out or rescue compared to the WT. Knock-out = Tryptophan hydroxylase (<i>Tph1</i>) deficient mice; Rescue = <i>Tph1</i> knock-out + 100 mg/kg daily injections of 5-hydroxytryptophan.
