The Neuropeptide APGWamide as a Penis Morphogenic Factor (PMF) in Gastropod Mollusks Eva Oberdörster, Jocelyn Romano, Patricia McClellan-Green Integrative and Comparative Biology, Volume 45 (1) - Jan 1, 2005 Read Article Download PDF Share Full Text for Free (beta) 5 pages Article Details Recommended References Bookmark Add to Folder Cite Social. APWGamide (APWGa) controls molluskan male reproductive behavior. Male mollusks possess this peptide more in the nerve cells, particularly in the reproductive accessory organ, in comparison with females. Discovery APWGa was originally isolated from the CNS of molluskan Fusinus ferrugineus by assaying inhibitory effects on the twitch contraction [1]. In addition, immunohistochemistry for APGWamide expression in abdominal areas was done on female, male and im-posex snails collected from the wild. The pattern of APGWamide in imposex snails was similar to male snails, showing large patches of immuno-reactive areas in the top portion of the visceral mass. The amidated tetrapeptide Ala-Pro-Gly-Trp-NH 2 (APGWamide) and related peptides are conserved neuropeptides playing a key role in the control of male copulation behavior in gastropods [9], which are also present in bivalves [16], [21] as well in cephalopods [20], where they inhibit contraction of mature oviduct.

Has-APGWamide is predicted to encode 10 copies of APGWamide, 6 connecting peptides (CPs), and a C-terminal peptide, and is most similar to the Aplysia californica APGWamide gene [ 30] (Figure 1 B); H. asinina CPs are numbered using the system for Aplysia [ 31 ]. FMRFamide-related peptides act synergistically with other mollusk-specific neuropeptides like APGWamide-related peptides. In H. aspersa, some cells contain both the APGWamide and FMRFamide; these cells may have dual projections in both the penial nerve and the nervus cutaneous pedalis primus dexter ( 71 ). class="algoSlug_icon" data-priority="2">Web.

Gastropod molluscs are among the most abundant species that inhabit coral reef ecosystems. Many are specialist predators, along with the giant triton snail Charonia tritonis (Linnaeus, 1758) whose diet consists of Acanthaster planci (crown-of-thorns starfish), a corallivore known to consume enormous quantities of reef-building coral. C. tritonis are considered vulnerable due to.

We investigated whether neuropeptides which control sexual differentiation in mollusks can induce imposex-a condition where female snails grow male accessory sex organs after exposure to tributyltin (TBT). Mud snails, Ilyanassa obsoleta, were dosed with one of four neuropeptides: APGWamide, conopressin, LSSFVRIamide, or FMRFamide for seven or fourteen days. TBT and testosterone (T) were used.

Molecular cloning of a cDNA encoding the neuropeptides APGWamide and cerebral peptide 1: Localization of APGWamide-like immunoreactivity in the central nervous system and male reproductive organs ofAplysia. Another neuropeptide, Ala-Pro-Gly-Trp-NH2 ( APGWamide ), can also control sexual maturation and reproduction of mollusks. APGWamide can function as a central and peripheral neuromediator in the control of male reproduction of Lymnaea stagnalis ( Van Golen et al., 1995; De Boer et al., 1997) and Ilyanassa obsolete ( Oberdorster et al., 2005 ). class="algoSlug_icon" data-priority="2">Web. class="algoSlug_icon" data-priority="2">Web. The agonistic effect of APGFamide was found to be weak. Minakata et al. [13] suggested that N-terminally extended APGWamide-related peptides were less potent than APGWamide. In the present study, it was shown that C-terminally extended APGWamide-related peptides were also less potent than APGWamide or had no agonistic effect. Conference Description. The 2022 GRC Chemistry and Biology of Peptides conference will highlight the diversity of peptide science. Attendees will engage in discussions regarding discoveries, challenges and advances in the design, synthesis, characterization and translation of peptides. Sessions focusing on chemical biology and organic synthesis.

FMRFamide-related peptides act synergistically with other mollusk-specific neuropeptides like APGWamide-related peptides. In H. aspersa, some cells contain both the APGWamide and FMRFamide; these cells may have dual projections in both the penial nerve and the nervus cutaneous pedalis primus dexter ( 71 ). Expression of the APGWamide gene is detected in the CNS of both adult animals and noncopulating juveniles. Peptides derived from the APGWamide prohormone are probably involved in the control of a part of the male mating behavior and have both central and peripheral targets.
