中文摘要Generating transgenic fish with desirable traits (e.g., rapid growth, larger size, etc.) for commercial use has been hampered by concerns for biosafety and competition if these fish are released into the environment. These obstacles may be overcome by producing transgenic fish that are sterile, possibly by inhibiting hormones related to reproduction. In vertebrates, synthesis and release of gonadotropin (GtH) and other reproductive hormones is mediated by gonadotropin-releasing hormone (GnRH). Recently two cDNA sequences encoding salmon-type GnRH (sGnRH) decapeptides were cloned from common carp (Cyprinus carpio). This study analyzed the expression of these two genes using real-time polymerase chain reaction (RT-PCR) in different tissues carp at varying developmental stages. Transcripts of both genes were detected in ovary and testis in mature and regressed, but not in juvenile carp. To evaluate the effects of sGnRH inhibition, the recombinant gene CAsGnRHpc-antisense, expressing antisense sGnRH RNA driven by a carp beta-actin promoter, was constructed. Blocking sGnRH expression using antisense sGnRH significantly decreased GtH in the blood of male transgenic carp. Furthermore, some antisense transgenic fish had no gonadal development and were completely sterile. These data demonstrate that sGnRH is important for GtH synthesis and development of reproductive organs in carp. Also, the antisense sGnRH strategy may prove effective in generating sterile transgenic fish, eliminating environmental concerns these fish may raise. (c) 2007 Published by Elsevier B.V.
