摘要

目的

探讨精浆蛋白在成年男性特发性弱精子症中的差异表达情况。

方法

纳入2017年1-5月我院泌尿外科门诊特发性弱精子症患者15例作为试验组

年龄24~47岁。同时

纳入精液正常成年男性15例作为对照组

年龄21~44岁。用等重同位素多标签相对定量蛋白质组学(isobaric tags for relative and absolute quantitation

iTRAQ)的方法研究成年男性正常精浆蛋白以及特发性弱精子症患者的精浆蛋白表达情况。

结果

共发现精浆中2 784个蛋白质。其中

与正常组相比

特发性弱精子症患者精浆中表达上调蛋白数为14个

精浆中表达下调蛋白数为79个(表达差异倍数＞1.2倍

且

0.05)。经斑点印迹技术验证蛋白INF2表达水平与

iTRAQ结果一致。经GO(gene ontology)蛋白功能注释及富集分析

特发性弱精子症精浆中差异蛋白功能主要包括调节钙离子跨膜转运、胞浆内转运以及螯合、蝶呤钼辅因子合成及代谢、调节铜离子跨膜转运等。经KEGG蛋白通路注释及富集分析

特发性弱精子症精浆中差异蛋白主要富集于叶酸生物合成、金黄色葡萄球菌感染等通路。

结论

特发性弱精子症患者精浆蛋白同正常成年男性精浆蛋白存在差异

其可能是引起特发性弱精子症的原因。

Abstract

Objective

To explore the differential expression profile of the seminal plasma proteome in idiopathic asthenospermia.

Methods

Fifteen patients (24~47 years old) with identified idiopathic asthenospermia admitted in our outpatient department from January to May 2017 were enrolled as the experimental group.Fifteen adult males (21~44 years old) with normal semen were enrolled as the control group.Isobaric tags for relative and absolute quantitation (iTRAQ) labeling was used to determine the expression of seminal plasma proteins in the 2 groups of males.

Results

There were 2 784 seminal plasma proteins found in this study.Compared with the normal group

there were 14 proteins up-regulated and 79 down-regulated in seminal plasma of idiopathic asthenospermia patients (the difference was more than 1.2 times

0.05).Dot blotting confirmed that INF2 expression level was consistent with the result of iTRAQ.According to the Gene Ontology (GO) annotation and enrichment analysis

the differential proteins were mainly involved in the regulation of calcium ion transmembrane transport

calcium ion intracellular transport and calcium ion sequestering

molybdopterin cofactor metabolic/biosynthetic process

and copper ion transmenbrane transport.According to the results of KEGG protein pathway annotation and enrichment analysis

the differential proteins were mainly involved in folate biosynthesis

Staphylococcus aureus

infection and other pathways.

Conclusion

There are proteomic differences in seminal plasma between idiopathic asthenospermia and normal semen

which may be the cause of idiopathic asthenospermia.
