Expression patterns and behavioral effects of conopressin and APGWamide in the nudibranch Berghia stephanieae.

ABSTRACT: The highly conserved oxytocin/vasopressin family of nonapeptides plays many roles across the animal kingdom, from osmoregulation to reproductive physiology. We investigated the expression patterns and pharmacological effects of the gastropod ortholog of this peptide, conopressin, along with another peptide involved in gastropod reproduction, APGWamide, in the nudibranch Berghia stephanieae. A brain transcriptome was used to identify and annotate the gene sequences for the peptides and one conopressin receptor. In-situ hybridization chain reaction showed that many neurons in the brain expressed these peptides. However, the peptide genes were co-expressed by only three neurons, which were in the right cerebral ganglion, the same side on which the reproductive organs are located. A conopressi
