SYNOPSIS. The Y-organs of crustaceans secrete ecdysteroids (molting hormones) and are regulated (negatively) by a neurosecretory peptide, molt-inhibiting hormone (MIH). Signaling path(s) in Y-organs were explored that connect MIH receptors ultimately

The Y-organs of crustaceans secrete steroid hormones (ecdysteroids) which are responsible for molting and regeneration. The Y-organs in turn are controlled (negatively) by the eyestalk peptide, molt-inhibiting hormone (MIH). We are exploring the sign

The Y-organs of Cancer antennarius secrete the hormones ecdysone (E) and much greater amounts of 3-dehydroecdysone (3DE), but the dominant derivative in the circulation is 20-hydroxyecdysone (20E). The uptake and clearance of E, 3DE, and metabolites

Ecdysteroid hormones in crustaceans are synthesized from cholesterol in the Y-organs. Circulating cholesterol is bound to high-density lipoprotein (HDL). Experiments were conducted to find the mode of cholesterol uptake by Y-organ cells. The working

Y-organs are the ecdysial glands of crustaceans, responsible for synthesis and secretion of ecdysteroid hormones. For this purpose, the glands acquire cholesterol as obligate precursor entirely from circulating high-density lipoprotein (HDL). A prece

Cholesterol is the obligate precursor for ecdysteroid hormone synthesis by the ecdysial glands (Y-organs) in crustaceans, and all cholesterol in the hemolymph is bound to high-density lipoprotein (HDL). The mechanism was studied of how Y-organ cells

A pair of glands (Y-organs) in crustaceans synthesize and secrete ecdysteroid hormones; the obligate precursor for synthesis is circulating cholesterol. Ecdysteroid output by the Y-organs is regulated negatively by an eyestalk neurosecretory peptide,

Y-organs of the xanthid crab, Menippe mercenaria, secrete ecdysteroid hormones in vitro, apparently both 3-dehydroecdysone and 25-deoxyecdysone. Studies were initiated on the biosynthetic path(s), in which cholesterol is converted to these ecdysteroi

1. Neuronal mapping studies were conducted in brain and eyestalks of the crab, Cancer antennarius , directed to finding the unit(s) that control neurosecretion of molt-inhibiting hormone (MIH). Control is known to be serotonergic. 2. Nine clusters of
