中文摘要
为了开发利用与生殖相关的脑神经内分泌因子诱导性成熟的新技术,我们从鳗鱼和蜂窝石斑鱼的大脑中分离出kisspeptin及其受体(GPR54)基因,并证明这些基因在鳗鱼的性成熟和石斑鱼的性别变化中起着关键作用。此外,性腺促性腺激素释放激素类似物或长光周期和高水温处理对性未成熟雌石斑鱼在非繁殖季节的性成熟有促进作用。
英文摘要
To develop new techniques for induction of sexual maturation using brain neuroendocrine factors related to reproduction, we newly isolated genes of kisspeptin and their receptors (GPR54) from brains of eels and honeycomb groupers and demonstrated that these genes play critical roles on the sexual maturation in the eel and the sex change in the grouper. Moreover, treatments of gonadotropin-releasing hormone analogue or of long photoperiod with high water temperature to sexually immature female grouper induced sexual maturation at period of non-breeding season.
