促性腺激素释放激素（GnRH）是脊椎动物（包括鱼类）中调节生殖的主要神经内分泌激素。近年来，GnRH在贝类、甲壳类和软体动物中的存在及其在生殖中的功能已被证实。有趣的是，贝类GnRH不聚集在有鳍鱼类GnRH，这表明gnrh基因的多样性和它们在动物界的进化。GnRH类似物已被化学合成并成功地用于鱼类的诱导繁殖。GnRH在贝类诱导成熟和产卵中的作用研究有限。本文报道了贝类GnRH cDNA的最新信息，已成功地分离出的一些软体动物物种，并将有助于在受控条件下的贝类养殖。此外，该文件强调了GnRH在鱼类研究中的几何作图，表明鱼类GnRH信息的快速积累及其在鱼类生殖生物学和内分泌学中的重要性。
Gonadotropin-releasing hormone (GnRH) is the major neuroendocrine hormone regulating reproduction in vertebrates, including finfish. In recent years, presence of GnRH and their function in reproduction has been confirmed in shellfish, crustaceans and molluscs. Interestingly, shellfish GnRH do not cluster within finfish GnRH, suggesting diversity in gnrh genes and their evolution in animal kingdom. GnRH analogues have been synthesized chemically and successfully used in induced reproduction of finfish. Studies on GnRH potency in induced maturation and spawning of shellfish are limited. The present paper report the recent information of shellfish GnRH cDNAs that have been successfully isolated in number of molluscan species, and would help in the farming of shellfish under controlled conditions. Also, the paper highlights the scintometric mapping of GnRH research in fish, suggesting rapid accumulation of information on fish GnRH and their importance in fish reproductive biology and endocrinology.
