摘要：本研究为了分析由重离子辐照引起的绵羊精子蛋白质组学变化,用二维凝胶电泳分离精子蛋白,凝胶用考马斯亮蓝染色。PDQuest8.0软件检测分析差异表达蛋白斑点并经高效液相色谱串联离子阱质谱鉴定。结果显示:辐照后的精子凝胶图谱上有4个蛋白质斑点表达上调,1个蛋白质斑点缺失,这5个蛋白质斑点经鉴定后,在国际生物信息学中心数据库搜索到相对应的2种蛋白质:烯醇酶和烯醇酶1,在辐照后的精子中这2种蛋白质表达上调。研究表明:重离子辐照会引起绵羊精子蛋白质组学变化,通过对差异蛋白质的研究探索重离子辐照对绵羊精子生理功能的影响,为重离子辐照绵羊育种提供理论依据。
The objective of this study was to investigate the proteome changes induced by heavy ion radiation using irradiated ram sperm by a two-dimensional electrophoresis （2 -DE） analysis. The 2D gels were stained with Coomassie Brilliant Blue. Differentially expressed proteins were detected by PDQuest 8.0 software and subjected to ion trap mass spectrometer equipped with a surveyor HPLC system, and differential protein spots were identified. Results showed there are five differential protein spots in irradiated sperm gels, four up-regulated protein spots and one spot missed. The differentially expressed protein spots were identified to be two up-regulated proteins including enolase, and enolase 1. It was concluded there was proteome changes induced by heavy ion radiation in ram sperm, which may be useful to clarify the physiology state of ram sperm in heavy ion radiation and provide a theoretical basis for radiation ram breeding.
