| 摘 要： | Ca^2＋是动物受精过程中卵内重要的第二信使，它对于皮质颗粒的排放、减数分裂的恢复、原核形成等过程具有重要的作用，受精过程中Ca^2＋的释放机制研究是当今受精生物学研究的热点之一，已有的研究结果表明动物卵子在受精过程中有三种Ca^2＋释放机制：由1，4，5，三磷酸肌醇引发内质网中储存的Ca^2＋释放、由环腺苷酸二核苷酸磷核糖引发与其相关联的钙库Ca^2＋释放和烟酸腺嘌呤二核苷酸磷酸引发的与其相关联的钙库Ca^2＋释放．

| Abstract: | Eggs from different animal species were studied to date elicit single or repetitive Ca~(2+) transients in(response) to fertilizing sperm.As an important second messenger,Ca~(2+) triggers a broad range of cellular reactions,(including) cortical granule release,completion of meiosis and pronuclear formation in oocyte.There are three mechanisms for Ca~(2+) release:inositol 1,4,5-trisphosphate pathway,cyclic ADP-ribose pathway and nicotinic acid adenine(dinucleotide) phosphate pathway. |
