On Thursday 9 May 1991, the world awoke to front-page news of a breakthrough in biological research. From Washington to Wollongong, newspapers, radio and TV were abuzz with the story of a transgenic mouse in London called Randy. Why was this mouse so special? The mouse in question was a chromosomal female (XX) made male by the presence of a transgene containing the Y chromosome gene Sry This sex-reversal provided clear experimental proof that Sry was the elusive mammalian sex-determining gene. Twenty-five years on, we reflect on what this discovery meant for our understanding of how males and females arise and what remains to be understood.
1991年5月9日星期四,全世界醒来看到了生物研究取得突破的头版新闻。从华盛顿到卧龙岗,报纸、广播和电视都在热议一只名叫兰迪的伦敦转基因小鼠的故事。这只小鼠为何如此特别?这只小鼠是染色体雌性(XX),由于存在一个包含Y染色体基因Sry的转基因而变成了雄性。这种性别反转提供了明确的实验证据,证明Sry就是难以捉摸的哺乳动物性别决定基因。二十五年过去了,我们反思这一发现对我们理解雄性和雌性如何产生意味着什么,以及还有哪些有待理解的问题。
