Pituitary adenylate cyclase-activating peptide (PACAP) and PAC1 receptor in the testis of cartilaginous fish Torpedo marmorata: A molecular and phylogenetic study

Finally, we demonstrated that in T. marmorata PACAP and its PAC1 receptor are synthesized directly in the testis, where they show a wider localization than mammals, suggesting that this neuropeptide is involved in the control of Torpedo spermatogenesis.
