睾丸决定基因SRY在哺乳动物中,特别是在小鼠和其他哺乳动物之间,无论是在蛋白质结构还是表达调控方面都不是很保守。为了评估 SRY 系统发育保守性的功能,我们在 XX 转基因小鼠性腺中表达了山羊基因 (gSRY)。在这里,我们表明,尽管存在山羊表达谱,但 gSRY 仍能诱导睾丸形成。我们的结果表明,非小鼠 SRY 可以在 XX 小鼠中诱导性逆转,从而表明该睾丸决定基因在哺乳动物物种中具有保守的分子作用机制。 (c) 2006 年欧洲生化学会联合会。由 Elsevier B.V. 出版。保留所有权利。
The testis-determining gene SRY is not well-conserved among mammals, particularly between mouse and other mammals, both in terms of protein structure and of expression regulation. To evaluate SRY phylogenic conservation in regards to its function, we expressed the goat gene (gSRY) in XX transgenic mouse gonads. Here, we show that gSRY induces testis formation, despite a goat expression profile. Our results demonstrate that sex-reversal can be induced in XX-mice by a non-mouse SRY thus suggesting a conserved molecular mechanism of action of this testis-determining gene across mammalian species.
