“…CHH in many crustacean species is associated with multiple functions and tissue-specific structural isoforms (Yasuda et al, 1994;Aguilar et al, 1995;Chung and Webster, 1996;Chang et al, 1999;Ollivaux and Soyez, 2000;Chung and Webster, 2004). Eyestalk-CHH (ES-CHH), present in a moult stage-independent manner, is associated with hyperglycaemia, osmoregulation and the inhibition of ecdysteroid and methyl farnesoate synthesis (Webster and Keller, 1986;Liu et al, 1997;Khayat et al, 1998;Chung et al, 1999;Webster et al, 2000;Spanings-Pierrot et al, 2000;Tsutsui et al, 2005). The presence of CHH in the brain (eyestalk)-gut axis has also been reported in Carcinus maenas (Kegel et al, 1989;Weidmann et al, 1989;Chung et al, 1999).…”

SUMMARYCrustacean hyperglycaemic hormone from the pericardial organ (PO-CHH) is a CHH-related neuropeptide but its function and target tissues are not known in crustaceans. To investigate this issue, we employed radiolabelled ligand binding and cGMP assays, using eyestalk-CHH (ES-CHH) as a reference neuropeptide. The membranes were prepared from various tissues of Callinectes sapidus: hepatopancreas, hindgut, midgut, gills, heart, abdominal muscles and scaphognathites. Like ES-CHH, recombinant PO-CHH (rPO-CHH) specifically bound to the membranes of scaphognathites=abdominal muscles>midgut>gills> heart>hindgut and hepatopancreas (list order corresponds to the number of binding sites). The specific binding sites of 125 I-ES-CHH in hepatopancreas and gills were saturable and displaceable. The abdominal muscle membrane binding sites were specific and saturable to both CHHs. These binding sites were displaced by homologous neuropeptides, but poorly displaced by the heterologous counterpart. As for the second messenger, the expected increment (3-to >20-fold) in the amount of cGMP produced by ES-CHH was noted in most tissues tested except midgut. Recombinant PO-CHH increased cGMP production 1.5-to 4-fold in scaphognathites, heart, midgut, hindgut and abdominal muscles. The results obtained from the binding study suggest that PO-CHH also has multiple target tissues of which abdominal muscles and scaphognathites are the primary ones. The differences in the primary amino acid sequences of PO-CHH and ES-CHH, particularly in the C-terminal region and in the amidation at Cterminus, may contribute to the truncated responses of hyperglycaemia, cGMP stimulation and binding affinity.

“…However, it is now widely appreciated that these hormones are pleiotropic; related biological functions include secretagogue activity (Sedlmeier, 1988) and lipid mobilisation (Santos et al, 1997), and a plethora of functions unrelated to regulation of energy mobilisation have now been discovered. These include the repression of ecdysteroid synthesis by the Y-organ, and thus a possible involvement in moult control (Webster and Keller, 1986;Chang et al, 1990), the inhibition of reproductive processes via the inhibition of methyl farnesoate synthesis (Liu et al, 1997), and the inhibition of vitellogenin (Vg) mRNA, protein synthesis (Khayat et al, 1998) or Vg gene expression (Tsutsui et al, 2005). An involvement in iono-osmoregulatory processes is also documented (Charmantier-Daures et al, 1994;Chung et al, 1999;Serrano et al, 2003), and it appears that CHH is involved in stimulation of ion transport across respiratory epithelia (SpaningsPierrot et al, 2000) and in dipsogenesis during ecdysis (Chung et al, 1999).…”

SUMMARYThe Christmas Island red crab Gecarcoidea natalis undergoes extreme changes in metabolic status, ranging from inactivity during the dry season, to a spectacular annual breeding migration at the start of the wet season. The dramatic change in metabolic physiology that this polarisation entails should be reflected in changes in endocrine physiology, particularly that of the crustacean hyperglycaemic hormone (CHH), of which we know relatively little. CHH levels were measured using a novel ultrasensitive time-resolved fluoroimmunoassay (TR-FIA), together with metabolites (glucose, lactate), in the field at several scales of temporal resolution, during migratory activities (wet season) and during the inactive fossorial phase (dry season). Release patterns of CHH were measured during extreme (forced) exercise, showing for the first time an unexpectedly rapid pulsatile release of this hormone. A seasonally dependent glucose-sensitive negative-feedback loop was identified that might be important in energy mobilisation during migration. Haemolymph lactate levels were strongly correlated with CHH levels in both field and experimental animals. During migration, CHH levels were lower than during the dry season and, during migration, daytime CHH levels (when most locomotor activity occurred) increased. However, the intense dawn activity in both dry and wet seasons was not always associated with repeatable hyperglycaemia or CHH release. The results obtained are discussed in relation to the life history and behaviour of G. natalis.

“…Therefore, ovarian tissue incubation is often used to search for factors affecting vitellogenin gene expression, which could be VIH or vitellogenesisstimulating hormone (VSH). Vitellogenin mRNA lev- els in ovarian fragments spontaneously increased during the incubation period in this assay system (Tsutsui et al 2005a; Fig. 18A), and homologous sinus gland extract reduced expression to 20-45% of control levels at concentrations of 0.001 to 10 sinus gland equivalents/mL (Fig.…”

“…Pej-SGP-III significantly inhibited vitellogenin gene expression in a dose-dependent manner, whereas recombinant Pej-SGP-IV, as well as Pej-MIH-B for which transcript is much more abundant in the thoracic and abdominal ganglia than in the eyestalks, reduced vitellogenin expression at 100 nM. However, those effects were not significant (Tsutsui et al 2005a; Fig. 19).…”

“…Mode of action of VIH on the ovary: experiments using secondary messengers in ovarian incubation to examine vitellogenin gene expression Vitellogenin synthesis in the ovary is directly inhibited by vitellogenesis-inhibiting hormone (VIH) (Tsutsui et al 2005a). Because actions of peptide hormones are mediated by intracellular signaling pathways, the actions of VIH are expected to be mediated via secondary messengers in the ovary.…”

Shrimp culture is a significant world-wide industry, with current production levels reaching over 3 million tons per year. The expansion of the industry has given rise to the problems of environmental deterioration due to intensive-scale culture, and the outbreak of disease. While many of these issues are now being sufficiently addressed, the establishment of sustainable seed production technology is an area that should be given continued attention. In this regard, it remains difficult to control reproduction under hatchery conditions for a large number of commercially-important species. At present, an understanding of reproductive mechanisms in Crustacea is not complete, although in recent years, a great deal of knowledge has accumulated on vitellogenin structure, processing, and synthetic site in a number of economically-important species. This monograph will cover the current status of research on vitellogenin in decapod crustaceans, especially prawns and shrimp, and discuss mechanisms of vitellogenin synthetic control, both demonstrated and postulated. The monograph will also present current knowledge of crustacean vitellogenin receptors, and cover related facets of reproductive development, such as mechansisms of cortical rod formation and the utilization of vitellin during embryogenesis. Finally, future directions for this research and potential applications to aquaculture will be discussed.
