摘要:

为了解鸡法氏囊发育过程中转录组的变化,应用鸡基因表达谱芯片对从18胚龄、10和30日龄SPF鸡法氏囊组织抽提和纯化的mRNA进行芯片杂交,对差异表达基因进行了GO功能分类和KEGG信号通路分析,并利用荧光定量PCR验证了部分差异表达基因。结果表明,法氏囊总RNA的基因检出率在79%~85%,30日龄雏鸡与18胚龄鸡胚相比、10日龄雏鸡与18胚龄鸡胚相比和30与10日龄雏鸡相比分别筛选到5 043、2 368和1 874条差异表达基因,主要涉及到结合功能、细胞组成、代谢过程、细胞加工、生物学调节等功能,一些差异表达基因参与细胞因子及其受体相互作用通路、Toll样受体(TLR)信号通路、核苷酸寡聚化域样受体(NLR)信号通路、哺乳动物雷帕霉素靶蛋白(mTOR)信号通路等。结果表明在法氏囊发育过程中,基因表达谱发生了很大变化,表明法氏囊发育是多基因参与的复杂的生物学过程,但这些差异表达基因在法氏囊的发育过程中的作用及其对法氏囊的功能的影响还有待于深入研究。

Abstract:

To investigate the dynamic changes of gene expression in chicken bursa,the total mRNA extracted from SPF chicken bursa at 18 embryo-days,10 and 30 days-old were hybridized using Agilent Chicken Genome Array.The differentially expressed genes were analyzed with gene ontology (GO) and KEGG to screen the significant signaling pathway.Several differentially expressed genes were verified with real time quantitative PCR.The results showed that the gene detection rate were 79%-85%,and 5 043,2 368 and 1 874 differential expression genes were identified when comparing chicken of 30 days-old with embryo of 18 embryos-days,chicken of 10 days-old compared with embryo of 18 embryos-days,and chicken of 30 days-old compared with chicken of 10 days-old,respectively.Differentially expressed genes were involved in binding functions,cell component,metabolic progress,cell progress,biological regulation,etc.Additionally,cytokine signaling pathway,Toll-like receptor signaling pathway,NOD-like receptor signaling pathway,and mTOR signaling pathway were also included.Gene expression profile of chicken bursa of Fabricius was successfully analyzed,and the function of differentially expressed genes need further study to understand the molecular mechanism of the development in chicken bursa of Fabricius.
