摘要

20 世纪 80 年代标志着分子生物学时代的开始;利用复杂的基因构建物创建小鼠模型的新技术在各个科学领域的应用如日中天。特别是在内分泌学领域,出现了一系列新型转基因小鼠模型,包括基因敲除和基因敲入,从而能够阐明表型与特定基因和基因网络之间的联系。在此期间,利用转基因小鼠创建新细胞模型的研究也在兴起。在我看来,梅隆等人的研究是一项重要的开创性研究,它改变了促性腺激素释放激素(GnRH)研究乃至整个生殖生物学的格局。帕梅拉-梅隆(Pamela Mellon)刚刚结束在哈佛大学与汤姆-马尼亚蒂斯(Tom Maniatis,这位写下分子克隆之书的科学家是当时所有实验室的主力军)的博士后研究,当时她还是索尔克研究所(Salk Institute)的新教员,正在探索针对啮齿动物肿瘤发生的新技术。当时的想法是将特定基因(本例中为大鼠 Gnrh1)的 5′调控区克隆到强效癌基因 SV40 T 抗原上,目的是促进特定细胞类型的肿瘤发生。由于 GnRH 在下丘脑中高度表达和定位,转基因动物的大脑中出现了肿瘤,这些肿瘤可以切除并在培养皿中培养成细胞。这些细胞模型的出现彻底改变了对 GnRH 神经元的研究,并创造了在此之前无法实现的信息水平和类型。
