| Despite the fact that the involvement of environmental factors in the physiology of the japanese oyster C. gigas is fully described, regulatory peptides are not known. In this study, we focused on peptidergic control of egg-laying. In order to characterize peptides involved in the regulation of egg-laying in C. gigas, the cuttlefish S. officinalis was used as a model. Firstly, regulatory peptides were investigated in the cuttlefish by peptidomic analysis. This approach led to the identification of eleven new ovarian regulatory peptides. Based on conserved tags, these peptides have been classified into two families: the SepCRPs (Sepia Capsule Releasing Peptides) and the OJPs (Ovarian Jelly Peptides). Released by oocytes into the genital coelom, they are... |
