BackgroundOysters impart significant socio-ecological benefits from primary production of food supply, to estuarine ecosystems via reduction of water column nutrients, plankton and seston biomass. Little though is known at the molecular level of what genes are responsible for how oysters reproduce, filter nutrients, survive stressful physiological events and form reef communities. Neuropeptides represent a diverse class of chemical messengers, instrumental in orchestrating these complex… 
Transcriptome Profiling of the Pacific Oyster Crassostrea gigas Visceral Ganglia over a Reproduction Cycle Identifies Novel Regulatory Peptides
The neuropeptides involved in the regulation of reproduction in the Pacific oyster (Crassostrea gigas) are quite diverse. To investigate this diversity, a transcriptomic survey of the visceral

TLDR
New insights are obtained into the neuropeptide signaling systems of holothurians, which will facilitate physiological studies that may enable advances in the aquaculture of sea cucumbers.
Identification and Characterization of Neuropeptides by Transcriptome and Proteome Analyses in a Bivalve Mollusc Patinopecten yessoensis
TLDR
This study sequenced and analyzed the transcriptome of nerve ganglia of Yesso scallop Patinopecten yessoensis, from which 63 neuropeptide genes were identified based on BLAST and de novo prediction approaches, and 31 were confirmed by proteomic analysis using the liquid chromatography-tandem mass spectrometry (LC-MS/MS).
Reproductive neuropeptides that stimulate spawning in the Sydney Rock Oyster (Saccostrea glomerata)
TLDR
This analysis of S. glomerata has identified neuropeptides that can influence the reproductive cycle of this species, specifically by accelerating gonadal maturation and triggering spawning.
Neuropeptides predicted from the transcriptome analysis of the gray garden slug Deroceras reticulatum
TLDR
The results provide comprehensive transcriptome data of the gray garden slug, with a more detailed focus on the rich repertoire of putative neuropeptide sequences, laying the foundation for molecular studies in this terrestrial slug pest.
Neuropeptidome of the Cephalopod Sepia officinalis: Identification, Tissue Mapping, and Expression Pattern of Neuropeptides and Neurohormones during Egg Laying.
TLDR
This work focuses on the neuropeptidome expressed during egg-laying through de novo construction of the CNS transcriptome using an RNAseq approach (Illumina sequencing) and in silico analysis of the transcriptome by characterizing and tissue-mapping neuropePTides by mass spectrometry.
In silico prediction of neuropeptides from the neural ganglia of Pacific abalone Haliotis discus hannai (Mollusca: Gastropoda)
TLDR
A novel insight is provided for further functional studies of abalone and other gastropod mollusks that shows that most of their biologically active residues were highly conserved with other invertebrate homologous neuropeptide residues.
Molecular insights into land snail neuropeptides through transcriptome and comparative gene analysis
TLDR
The results provide the most comprehensive picture of the molecular genes and proteins associated with land snail functioning, including the repertoire of neuropeptides that likely play significant roles in neuroendocrine signalling, and potentially stimulate advances in the biological control of land snail pest species.
Extensive conservation of the proneuropeptide and peptide prohormone complement in mollusks
TLDR
It is demonstrated that numerous peptides evolved much earlier than previously assumed and that key signalling elements are extensively conserved among extant mollusks.
Discovery of novel representatives of bilaterian neuropeptide families and reconstruction of neuropeptide precursor evolution in ophiuroid echinoderms
TLDR
An unprecedented investigation of the evolution of neuropeptide copy number over a period of approximately 270 Myr is performed by analysing sequence data from over 50 ophiuroid species, with reference to a robust phylogeny, and indicates that the composition of neuroPEptide ‘cocktails’ is functionally important, but with plasticity over long evolutionary time scales.

Functional characterization of a short neuropeptide F-related receptor in a lophotrochozoan, the mollusk Crassostrea gigas
TLDR
The results suggest that signaling of LFRFamide peptides through the Cg-sNPFR-like receptor might play a role in the coordination of nutrition, energy storage and metabolism in C. gigas, possibly by promoting storage at the expense of reproduction.

Some of the predicted hormones similar to Drosophila and vertebrate insulins, bursicon, the putative proctolin homolog PKYMDT and allatostatin C shows that despite significant differences the molluscan and arthropod neuropeptidomes are more similar than generally recognized.

Characterization of GnRH-related peptides from the Pacific oyster Crassostrea gigas
TLDR
This study characterized two GnRH-related peptides by mass spectrometry from extracts of the visceral ganglia of the Pacific oyster Crassostrea gigas, suggesting the involvement of Cg-GnRHs as synchronizers of nutritional status with energy requirements during reproduction in oyster and evidence for a role of Cgs as neuroregulators and as neuroendocrine factors in bivalve is discussed.
