Figure 3. Expression of genes in Gene Ontology category ‘peptide hormone processing’.

Expression of genes belonging to the Gene Ontology term ‘peptide hormone processing’ (GO:0016486). The four silver eel samples are grouped together to the left (silver eel 1–4 from left to right), while the gene expression for the yellow eel and the mature eel is placed to the right and displays an expression pattern similar to the silver eel samples. Genes involved in the processing of pro-opiomelanocortin are highly expressed (red), and include carboxypeptidase e, prohormone convertase 2 and neuroendocrine protein 7b2.
