While the role of eicosanoids in reproduction in vertebrate species has been well established, the role of these fatty acid derivatives in invertebrate species has not been as well characterized. The purpose of this study was to investigate changes in prostaglandins E2 and F2 alpha during vitellogenesis in the crayfish Procambarus paeninsulanus. In homogenates of crayfish ovaries taken at various stages of development, the rate of prostaglandin synthesis and the concentrations of prostaglandins E2 and F2 alpha increased during the final stages of yolk production just prior to ovulation. A gradual increase in prostaglandin E2 amounts was observed throughout the progression of vitellogenesis. The data suggests the possible involvement of prostaglandins in regulatory events associated with vitellogenesis and the induction of ovulation in Procambarus paeninsulanus.
虽然类二十烷酸在脊椎动物繁殖中的作用已得到充分证实，但这些脂肪酸衍生物在无脊椎动物中的作用尚未得到很好的表征。本研究的目的是调查半岛原螯虾卵黄发生过程中前列腺素E2和F2α的变化。在发育不同阶段采集的小龙虾卵巢匀浆中，排卵前卵黄生成的最后阶段前列腺素合成速率以及前列腺素E2和F2α的浓度增加。在整个卵黄发生过程中观察到前列腺素E2含量逐渐增加。数据表明前列腺素可能参与半岛原螯虾与卵黄发生和排卵诱导相关的调节事件。
