性腺功能低下(HPG)的小鼠缺乏完整的促性腺激素释放激素(GnRH)基因,因此无法繁殖。将完整的GnRH基因导入这些突变小鼠的基因组中,可以完全逆转性腺功能低下的表型。转基因HPG/HPG纯合子雌雄两性均能交配繁殖后代。垂体和血清中黄体生成素、卵泡刺激素和催乳素的浓度恢复到正常动物的水平。免疫细胞化学和原位杂交显示,在转基因HPG动物的相应下丘脑神经元中,GnRH的表达恢复,这表明导入的基因具有神经特异性表达。
The hypogonadal (hpg) mouse lacks a complete gonadotropin-releasing hormone (GnRH) gene and consequently cannot reproduce. Introduction of an intact GnRH gene into the genome of these mutant mice resulted in complete reversal of the hypogonadal phenotype. Transgenic hpg/hpg homozygotes of both sexes were capable of mating and producing offspring. Pituitary and serum concentrations of luteinizing hormone, follicle-stimulating hormone, and prolactin were restored to those of normal animals. Immunocytochemistry and in situ hybridization showed that GnRH expression was restored in the appropriate hypothalamic neurons of the transgenic hpg animals, an indication of neural-specific expression of the introduced gene.
