雄激素受体基因多态性与男性不育相关性研究进展

Androgen receptor gene polymorphisms and male infertility

雄激素受体(AR)是一种依赖配体的反式转录调节蛋白,参与雄激素的生理调节功能,其广泛存在于机体的各个组织,属于核受体超家族中的类固醇受体,在精子发生的过程中发挥重要的作用。雄激素通过与AR的结合,启动靶基因的表达,参与精子发生。AR基因多态性会改变自身结构,影响其与雄激素结合的亲和力,使雄激素下游靶基因不能够转录表达蛋白。随着DNA测序技术的发展,研究AR基因多态性与男性不育之间关系成为一大热点。本文主要综述AR基因多态性与男性不育之间的相关性。

The androgen receptor （AR） , as a ligand-dependent transcription protein and a member of the steroid receptor super- family widely present in the body, is involved in the adjustment of the function of androgens and plays an important role in spermatogen- esis. Androgens participate in spermatogenesis by binding AR and initiating the expression of the target gene. The polymorphisms of the AR gene may change the structure of AR and affect its avidity of binding androgens, making their downstream target genes unable to transcribe proteins. With the development of DNA sequencing techniques, studies on the association of the polymorphisms of the AR gene with male infertility have become a hot topic.
