摘要:

为了寻找不同品种马骨髓之间的差异表达基因,本研究构建了蒙古马-骨髓和纯血马-骨髓基因表达谱文库,经Illumina Miseq高通量测序,分别获得了7 219 956和7 116 170个有效reads;两个文库映射到11、8和1号染色体的reads最多,而映射到29、30和31号染色体的reads最少;两个文库共筛出318个差异表达基因,其中与免疫相关的基因有21个。GO功能富集分析结果表明差异表达基因与转运、细胞间信号传导、生物学过程和细胞质等有关;KEGG通路富集分析结果表明,差异最大的显著富集KEGG条目为神经系统。这些结果为研究马匹抗病力的遗传和免疫机理等提供基础数据。

Abstract:

To investigate the differential genes expression of bone marrow between different horse breeds,expression profiling libraries of Mongolian Horse-bone marrow and Thoroughbred-bone marrow were constructed.We obtained 7 219 956 and 7 116 170 useful reads by the Illumina Miseq sequencing,respectively.The most of reads in the 2 expression profiling libraries were maped on chromosome 11,chromosome 8 and chromosome 1,and the least of reads were maped on chromosome 29,chromosome 30 and chromosome 31.318 differentially expressed genes were found in 2 expression profiling libraries,including 21 immune-related genes.The Gene Ontology analysis showed that the differentially expressed genes were related to transport,cell-cell signaling,biological process and cytoplasm,etc.The Kyoto Encyclopedia of Genes and Genomes analysis indicated that nervous system was the most differentiated KEGG term.These results will provide data basis for further studies on the horses disease resistance and immune mechanism.
