Allurin: Exploring the Activity of a Frog Sperm Chemoattractant in Mammalsay to the uterus and subsequent spawning. Hydration of the egg jelly layers at spawning releases allurin as a chemoattractant that binds to the midpiece of . sperm in a dose-dependent manner. Gradients of allurin elicit directed swimming across a porous membrane in two-chamber assays and preferentia

Equatorin-Related Subcellular and Molecular Events During Sperm Priming for Fertilization in Miceocytosis, remodeling of the acrosomal substructure, and biochemical modification of related molecules. However, the mechanism underlying sperm priming process has remains unclear because of the number of molecules involved in sperm capacitation and the ensuing acrosome reaction (acrosomal exocytosis

Acrosome Reaction-Mediated Motility Initiation That Is Critical for the Internal Fertilization of Urfertilization of most amphibians, fertilization begins from motility initiation of the sperm by the hyposmolality of freshwater at spawning, whereas in internal fertilization, the sperm initiate motility without any change in osmolality. Acrosome reaction (AR)-mediated motility initiation is an init

Effect of Relaxin-Like Gonad-Stimulating Substance on Gamete Shedding and 1-Methyladenine Productionmediator in inducing these maturation and ovulation. GSS secreted from the nervous system acts on the ovary to produce 1-methyladenine (1-MeAde) as a maturation-inducing hormone. 1-MeAde induces germinal vesicle breakdown (GVBD) and follicular envelope breakdown (FEBD), releasing the oocyte from the

Incapacity of 1-Methyladenine Production to Relaxin-Like Gonad-Stimulating Substance in Ca2+-Free Se cells of their capacity to respond to gonad-stimulating substance (GSS). To elucidate the failure of GSS, this study examined the hormonal action of GSS on CaFSW-treated follicle cells of ., particularly the mode of signal transduction. GSS failed to stimulate the production of 1-methyladenine (1-M
