项目摘要
Approximately 10% of couples who attempt to conceive over a period of two years are unable to become pregnant. Previously, we have isolated many cDNA clones specifically expressed in mouse haploid germ cells using a subtracted cDNA library which was prepared by subtracting 17-day-old testis mRNAs from 35-day-old testis cDNAs. We report here the isolation and characterization of a newly isolated human cDNA clone encoding a protein, specifically expressed in haploid spermatids of the mouse testis. And also we examined the relationship between these genes variations and human male infertility. We identified specific variability in the transition nuclear protein genes (Tnps), protamine-1, protamine-2, SCOT-t of sterile male patients. Transition nuclear proteins (TPs), protamines are major nuclear proteins that replace nuclear histones during human spermiogenesis. We hypothesize that these SNPs/gene mutations cause male infertility.
大约10%的夫妇试图在两年内怀孕,但无法怀孕。在此之前,我们已经分离出许多在小鼠单倍体生殖细胞中特异性表达的cDNA克隆,使用的消减cDNA文库是通过从35日龄睾丸cDNA中减去17日龄睾丸mRNA制备的。我们在这里报告的分离和鉴定的一个新分离的人cDNA克隆编码的蛋白质,特异性地表达在小鼠睾丸的单倍体精子细胞。并探讨了这些基因变异与人类男性不育的关系。我们确定了不育男性患者的过渡核蛋白基因(Tnps),鱼精蛋白-1,鱼精蛋白-2,SCOT-t的特异性变异。过渡核蛋白(transition nuclear proteins,TPs)是人类精子发生过程中取代核内组蛋白的主要核蛋白。我们假设这些SNPs/基因突变导致男性不育。
