摘要: 试验旨在研究不同纤维直径的细毛羊皮肤组织中毛囊差异表达的蛋白质,探讨与羊毛细度相关的蛋白质功能。应用双向凝胶电泳技术建立细毛羊皮肤组织中毛囊差异表达蛋白质图谱;运用ImageMaster 2D Platinum软件检测细毛羊毛囊组织差异表达蛋白质;通过质谱鉴定技术和数据库比对等方法开展细毛羊皮肤组织毛囊特异性蛋白质分类和功能鉴定。结果成功鉴定出94个差异蛋白质,其中,相同年龄超细型细毛羊和细型细毛羊皮肤毛囊组织中有73个差异蛋白质;不同年龄的超细型细毛羊毛囊组织中有21个差异蛋白质。按功能属性划分得到了角蛋白、分子伴侣类蛋白、细胞骨架结构类蛋白、14-3-3蛋白、蛋白酶类、肌球蛋白、血清白蛋白和其他蛋白8类功能蛋白。结果提示,应用生物信息学技术分析这些差异蛋白与羊毛纤维直径的内在联系,为优质细毛羊的培育提供直接有效的基因资源信息,对提高羊毛品质具有重要的意义。

Abstract: The purpose of this paper was to study the differentially expressed proteins of hair follicles in skin tissue with different fiber diameter of Fine-wool sheep, and discussed the function of proteins related to wool fineness.The differentially expressed protein maps of Fine-wool sheep skin hair follicle were established by two-dimensional gel electrophoresis, and the differentially expressed protein spots were detected and analyzed by the ImageMaster 2D Platinum software, Fine-wool sheep skin hair follicle specific proteins were classified and functional identified by mass spectrum identification technology and database matching method.The results showed that 94 different proteins were successfully identified in Fine-wool sheep with different fiber diameter, including 73 different proteins between superfine wool sheep and Fine-wool sheep at the same age, and 21 different proteins of superfine wool sheep at the different age.According to the functional properties got eight kind of functional proteins, keratin, molecular chaperone protein, cytoskeleton protein, 14-3-3 protein, protease, myosin, serum albumin, other protein, respectively.These results indicated that the internal relation between the differentially expressed protein and the wool fiber diameter was analyzed by the bioinformatics knowledge, which would provide effective genetic resources information directly for high quality breeding of Fine-wool sheep, and had important practical significance for improving the quality of the wool.

Key words: Fine-wool sheep; two-dimensional gel electrophoresis; proteomics; differentially expressed proteins
