Stereospecific induction of starfish oocyte maturation by (8R)-hydroxyeicosatetraenoic acid.
Oocyte maturation (meiosis reinitiation) in starfish is induced by the natural hormone 1-methyladenine. This induction of meiotic divisions can be triggered also by four fatty acids: 5,8,11-20:3; 5,8,11,14-20:4 (arachidonic acid); 6,9,12,15-20:4; 5,8,11,14,17-20:5, all other fatty acids being completely inactive. This maturation triggered by eicosanoids occurs in the micromolar range and is fac...
متن کاملInduction and inhibition of oocyte maturation by EDCs in zebrafish
BACKGROUND Oocyte maturation in lower vertebrates is triggered by maturation-inducing hormone (MIH), which acts on unidentified receptors on the oocyte surface and induces the activation of maturation-promoting factor (MPF) in the oocyte cytoplasm. We previously described the induction of oocyte maturation in fish by an endocrine-disrupting chemical (EDC), diethylstilbestrol (DES), a nonsteroid...
متن کاملSpawning, in vitro Maturation, and Changes in Oocyte Electrophysiology Induced by Serotonin in Tivela stultorum.
Spawning was induced in both male and female Pismo clams by injecting 0.4 ml of 5 mM serotonin into the gonad. Spawned oocytes had already matured to metaphase I of meiosis or were undergoing germinal vesicle breakdown at the time of release. Prophase-arrested oocytes scraped from the ovaries of uninjected clams were induced to undergo germinal vesicle breakdown in vitro by incubating them with...
متن کاملOocyte maturation in starfish is mediated by the beta gamma-subunit complex of a G-protein
The stimulation of meiotic maturation of starfish oocytes by the hormone 1-methyladenine is mimicked by injection of beta gamma subunits of G-proteins from either retina or brain. Conversely, the hormone response is inhibited by injection of the GDP-bound forms of alpha i1 or alpha t subunits, or by injection of phosducin; all of these proteins should bind free beta gamma. alpha-subunit forms w...
متن کاملSynchronous gamete maturation and reliable spawning induction method in holothurians
Several years of research on the gametic development and spawning of different species of holothurians have produced results that find applications in aquaculture and fisheries management programs. The first set of data shows that sea cucumbers secrete a biologically active chemical which allows gamete synthesis synchrony among conspecifics. Laboratory experiments have revealed that the gametic...
