A Novel Neuropeptide with Molt-inhibiting Activity from the Sinus Gland of the Crayfish, Procamharus clarkii
TLDR
An extremely high level of activity was found in one fraction in reverse-phase HPLC, suggesting that the novel neuropeptide in this fraction may be a P. clarkii MIH.
Purification of molt-inhibiting hormone-like peptides with hyperglycemic activity from the eyestalks of the crab Scylla serrata
TLDR
Results of double immunodiffusion demonstrated the cross-reactivity of Homarus americanus MIH antiserum with the S. serrata MIH-like peptides, indicating the existence of close immunological relationship between crab and lobster peptides.
Cyclic AMP mediates the negative regulation of Y-organ ecdysteroid production
Regulation of protein synthesis in Y-organs of the blue crab (Callinectes sapidus): involvement of cyclic AMP.
TLDR
The combined results suggest that cAMP is involved in regulation of protein synthesis in C. sapidus Y-organs and the possibility of cross-talk between cAMP and other cellular signaling pathways in Y-organ proteins is investigated.
Hormonal Control of Molting in Decapod Crustacea
TLDR
Experiments demonstrate the presence of a molt-inhibiting hormone (MIH) in the sinus glands of juvenile lobsters, and data indicate that there must be another factor that ultimately regulates the circulating levels of the molting hormone.
Amino acid sequence of putative moult-inhibiting hormone from the crab Carcinus maenas

  • 1991
Putative moult-inhibiting hormone (MIH) was isolated from sinus glands of the shore crab Carcinus maenas, and its primary structure determined by automated Edman degradation of endoproteinase derived
Dissociated cell suspensions ofCarcinus maenas Y-organs as a tool to study ecdysteroid production and its regulation
TLDR
In vitro ecdysteroid production by dissociated Y-organ cells of the shore crabCarcinus maenas was characterized during short-term incubations and 25-deoxyecdysone was mainly produced.
Ecdysteroid biosynthesis in the crustacean Y-organ and control by an eyestalk neuropeptide
TLDR
Y-organs are discussed as useful models for study of steroidogenesis generally in animals at the cellular and molecular levels and results of in vitro experiments with 125I-labeled HDL suggest that the HDL-cholesterol complex is taken into Y-organ cells mediated by receptors for the HDL apoprotein.

Attempted Extraction of Crustacean Moulting Hormone from Isolated Y-Organs
TLDR
The Y-organs of Crustacea are physiologically (and morphologically) homologous to the prothoracic glands of insects, and have the same action as ecdysone, the moulting hormone or prothornic gland hormone of insects.
Biosynthesis of α-Ecdysone by Prothoracic Glands in vitro
An in vitro study in which isolated prothoracic glands of the Bombyx silkworm were cultured has provided definite evidence that the prothoracic gland is the site where molting hormone is synthesized.
Some effects of eyestalk removal on the Y-organs of Cancer irroratus Say.
TLDR
The Y-organ cells of Cancer irroratus contain numerous osmophilic granules both in control and destalked animals and it is proposed that this may be evidence of holocrine activity.
