Outline of Final Research Achievements |
Jellyfish oocytes undergo meiotic maturation in the ovary following a dark-light or light-dark transition (light or dark stimulation) and are then released as mature eggs. The present study provides evidence that a C-terminal amidated tetrapeptide, RPRPa, exists in neural-type cells in the ovarian epithelium and acts as maturation-inducing hormone (MIH) downstream of dark stimulation in Cladonema pacificum. Our data also indicate that slightly different neuropeptides may function in other jellyfish species. Furthermore, we confirm here that these neuropeptides can induce the release of sperm as well as eggs. To our knowledge, this is the first identification of peptidic MIHs among all animals.
